Configuration

Configuration

Every setting of Adventure Backpack is in one file, config/adventurebackpack.cfg. The game writes it the first time it starts, with every key and its comment. This page lists all 253 keys.

You can also edit the file from the game: in the Mods list, select Adventure Backpack and press Config. Changes made in the file need a restart of the game. Keys marked "Needs a restart" are read when items, blocks or keys are created, so they need one even with the config screen.

How the file is laid out

The file is a tree under adventurebackpack. First comes enabled, with one switch per system. Then each system has its own section with its own switches and numbers. The tables below drop the adventurebackpack prefix: enabled.hose is the hose key in the enabled section.

• A disabled system stays registered, so worlds and servers with different files still load. It is hidden, has no recipe and does nothing.
• Time is in ticks (20 per second) or seconds as each key says. Fluid is in millibuckets (mB): 1000 mB is one bucket. Speeds are in blocks per tick.
• Values outside the range are brought back into it. A value of the wrong type is replaced by the default.
• Use the same file on the server and on every client for the keys that say so. The render and keys sections only matter on the client.
• Keys from the older flat file (general section) move to the new places the first time the game starts, keeping their values. The table at the end lists them.

Contents

• Systems, Backpack, Abilities, Hose, Copter pack, Steam jetpack
• Scuba gear, Air compressor, Flamethrower, Fuels, Fuel station
• Inflatable boat, Boat motor
• Crossbow, Crossbow Magazine, Ammunition, Grappling hook, Sniper mode, Piston boots, Campfire, Sleeping bag
• Display, Keys, Tool swapping keys
• Backpacks in the world, Extra recipes, Small tweaks, Tool slots, Grave mods, Baubles
• Earlier flight values

Systems (enabled)

One switch per system. A disabled system stays registered, so worlds and servers still load, but it is hidden, has no recipe and does nothing.

Key	Type	Default	Range	What it does
enabled.abilities	boolean	true		Backpack abilities. When false every backpack is only cosmetic (the lightning transformation still works). Set it the same on server and clients.
enabled.hose	boolean	true		The Backpack Hose.
enabled.copterPack	boolean	true		The Copter Pack. It works when some loaded mod adds a fluid of fuels.list (BuildCraft, Forestry, Railcraft, GregTech...); with none of them it stays in the creative tab but cannot be crafted and does nothing.
enabled.steamJetpack	boolean	true		The Steam Jetpack.
enabled.scuba	boolean	true		The Scuba Gear, its Air Tanks and Diving Mask, and the Air Compressor.
enabled.inflatableBoat	boolean	true		The Inflatable Boat and the Motorized Inflatable Boat.
enabled.crossbow	boolean	true		The Clockwork Crossbow, its Crossbow Magazines and the Crossbow Bolts.
enabled.sleepingBag	boolean	true		The sleeping bag: deploying it from a placed backpack, and placing the Sleeping Bag item on its own (sleepingbag.placeable). Bags already on the ground still work and can be picked up.
enabled.pistonBoots	boolean	true		The Piston Boots: step assist, sprint speed and fall protection.
enabled.campfire	boolean	true		Cooking on the Campfire (see campfire.cooking). The campfire block, its recipe and the respawn point stay either way.
enabled.fuelStation	boolean	true		The Fuel Station block. When false it has no recipe, is hidden from the creative tab, and a placed one neither takes nor gives fuel (it can still be broken, and keeps its fuel).
enabled.flamethrower	boolean	true		The Flamethrower Pack, the Flamethrower nozzle and the Pyro Mask. When false they have no recipe, are hidden from the creative tab, and the nozzle does not fire. Set it the same on server and clients.

Spider backpack (abilities.spider)

Taming works with the Spider Backpack on. A tamed spider is kept for good, like a wolf: it does not despawn and it is not set free when its owner dies, logs out or changes dimension. The number of tame spiders of each player is saved with the world. See Backpacks.

Key	Type	Default	Range	What it does
abilities.spider.enabled	boolean	true		Spider Backpack: tame spiders and ride them. Wearing it, right click a spider with the tame item to try to tame it (like taming a wolf). A tamed spider is yours for good, like a wolf: it stays when you log out, die or change dimension, follows you (with or without the backpack) and climbs walls after you. Right click it to ride it while wearing the Spider Backpack; sneak and right click to make it sit or stand up; right click with the heal item to heal it; sneak and right click with the tame item to set it free. When false, no new spider can be tamed and nobody can ride one; tamed spiders keep following, sitting and healing.
abilities.spider.tameItem	string	minecraft:spider_eye		Item used to tame a spider, as modid:name. One is used up per try (not in creative). Sneaking and right clicking your tamed spider with it sets the spider free.
abilities.spider.tameChance	double	0.33	0.0 to 1.0	Chance that one try tames the spider (1 = always, the wolf is about 0.33).
abilities.spider.maxTamed	int	2	0 to 16	Tamed spiders a player may have at once. 0 turns taming off.
abilities.spider.tamedHealth	double	20.0	1.0 to 100.0	Max health of a tamed spider, in half hearts (a wild one has 16). Taming heals it to this. Applied again when a spider loads, so a change reaches existing spiders.
abilities.spider.healItem	string	minecraft:rotten_flesh		Item that heals your tamed spider on right click, as modid:name. One is used up per heal (not in creative); nothing happens at full health.
abilities.spider.healAmount	int	4	1 to 40	Health one heal item gives back, in half hearts.
abilities.spider.followStartDistance	double	6.0	2.0 to 32.0	A tamed spider starts walking to its owner when it is farther than this, in blocks.
abilities.spider.followStopDistance	double	3.0	1.0 to 32.0	It stops when it is this close to its owner, in blocks.
abilities.spider.teleportDistance	int	24	0 to 128	When it cannot walk to its owner and is farther than this, it jumps next to the owner like a wolf. 0 = never.
abilities.spider.teleportStuckDistance	int	8	0 to 64	When it gets no closer for twice stuckTicks and is at least this far from its owner, it jumps next to the owner. 0 = only when farther than teleportDistance.
abilities.spider.teleportCooldownTicks	int	100	20 to 1200	Ticks between two jumps next to the owner.
abilities.spider.verifyLoadsChunks	boolean	true		On login, and when the maxTamed limit blocks a tame, check that every spider counted for the player still exists, loading its chunk for a moment if needed. Counted spiders that are gone (removed by a world edit, for example) stop counting. When false, only spiders in loaded chunks are checked.
abilities.spider.smartClimb	boolean	true		A tamed spider plans its way up walls and towers to an owner above, and down cliffs to an owner below, and only climbs when it needs to (it does not hang on trees or walls while wandering). When false it climbs any wall it touches, like a wild spider, and only walks and teleports to follow.
abilities.spider.climbMaxHeight	int	32	2 to 128	Highest wall it climbs up or down to follow its owner, in blocks.
abilities.spider.safeDropHeight	int	3	0 to 8	It walks off a ledge this high or lower instead of climbing down it.
abilities.spider.repathTicks	int	10	5 to 40	Ticks between two path checks while it follows its owner.
abilities.spider.stuckTicks	int	60	20 to 400	Ticks without getting closer before it tries another way up; after twice this it jumps next to its owner (see teleportStuckDistance) or rests a while.

Key	Type	Default	Range	What it does
abilities.blaze.enabled	boolean	true		Blaze Backpack: fire immunity and burning punches.
abilities.blaze.fireImmunity	boolean	true		The wearer does not burn in fire or lava, like a magma cube (fire resistance, taken away when the backpack comes off).
abilities.blaze.fireResistanceTicks	int	5000	100 to 1000000	Length of the fire resistance effect it gives; it is renewed before it runs out (abilities.effectRefreshTicks).
abilities.blaze.punchFireSeconds	int	4	0 to 60	Seconds a punched mob or player burns. 0 turns the burning punch off.

Key	Type	Default	Range	What it does
hose.transferAmount	int	1000	1 to 64000	Millibuckets moved per click between the backpack and a tank block (suck or spill mode). Fluid blocks in the world are always one bucket.

Copter pack (copterpack)

It burns the fuels of fuels.list, so it works with any mod that adds one of them (BuildCraft, Forestry, Railcraft, GregTech...). Speeds are in blocks per tick. The defaults make flying expensive: a full tank gives roughly one to two and a half minutes of flight.

Key	Type	Default	Range	What it does

copterpack.airControl	double	0.03	0.0 to 0.5	Horizontal acceleration while flying. The top horizontal speed is about (0.02 + this value) / 0.09 blocks per tick: 0.03 gives about 11 blocks per second.
copterpack.maxAltitude	int	90	1 to 255	Height above which lift fades out. Climbing stops about liftSpeed x 100 blocks higher; hover mode keeps any height you already reached.
copterpack.itemPushRange	double	4.0	0.0 to 16.0	Distance in blocks at which the rotor blows dropped items away. 0 turns it off.
copterpack.itemPushIntervalTicks	int	2	1 to 20	The rotor looks for dropped items to blow away once every this many ticks.

Steam jetpack (steamjetpack)

The boiler needs a fluid called steam: another mod's, or the backpack's own (see ownSteamFluid). Speeds are in blocks per tick.

Key	Type	Default	Range	What it does
steamjetpack.sound	boolean	true		Play the boiler and thrust sounds (client only).
steamjetpack.ownSteamFluid	boolean	true		When no other mod (Railcraft, IC2...) registers a 'steam' fluid, register Adventure Backpack's own so the jetpack boils water without them. When another mod has steam, that one is used. Set it the same on server and clients. Needs a restart.
steamjetpack.waterCapacity	int	6000	1000 to 64000	Water tank capacity in millibuckets. Use the same value on server and clients. Needs a restart.
steamjetpack.steamCapacity	int	12000	1000 to 64000	Steam tank capacity in millibuckets. Use the same value on server and clients. Needs a restart.
steamjetpack.steamPerTick	int	20	0 to 1000	Steam spent per tick of thrust. With the defaults a full steam tank gives 30 seconds of thrust, and full water and steam tanks with a hot boiler about 90 seconds.
steamjetpack.ignitionSteam	int	150	0 to 64000	Steam spent at once each time the thrust starts, so taking off costs more than keeping it going. 0 turns it off.
steamjetpack.thrustFuelBurn	int	3	1 to 20	Ticks of firebox burn time used per tick of thrust (1 = as fast as idle). Coal burns 1600 ticks, so 3 makes one coal last about 27 seconds of thrust.
steamjetpack.thrustHeatLossTicks	int	10	0 to 1200	While thrusting the boiler loses one degree every this many ticks, down to the ambient temperature. With the fire lit it still heats up; without fuel a long flight cools it below boiling. 0 turns it off.
steamjetpack.heatingSpeed	double	1.0	0.1 to 10.0	How fast the firebox heats the boiler. 1 is the built-in curve (about 62 seconds from 25 to boiling at 100, then faster); 2 is twice as fast.
steamjetpack.coolingSpeed	double	1.5	0.1 to 10.0	How fast the boiler cools without fire. 1 is the old curve (from 200 to 100 in 5 minutes); 1.5 cools it in about 3 minutes and 20 seconds.
steamjetpack.waterIntake	int	2	0 to 1000	Millibuckets of water taken per tick while the wearer is in water.

steamjetpack.maxRiseSpeed	double	0.28	0.01 to 2.0	Top climbing speed.
steamjetpack.airControl	double	0.02	0.0 to 0.5	Horizontal acceleration while thrusting.
steamjetpack.maxAltitude	int	90	1 to 255	Height above which thrust fades out. Thrust holds you at about maxRiseSpeed x 100 blocks higher.

scuba.breathableFluids	string list	air, oxygen		Fluids the tanks and the compressor take, by registered name (air of GregTech or Adventure Backpack, oxygen of GregTech, Galacticraft or Mekanism...). When the 'air' fluid exists every one of them is stored as air. Set it the same on server and clients. Needs a restart.
scuba.ownAirFluid	boolean	true		When no other mod (GregTech) registers an 'air' fluid, register Adventure Backpack's own so the hand pump and the furnace of the compressor can make air. When another mod has air, that one is used. Set it the same on server and clients. Needs a restart.
scuba.airItems	string list	ic2:airCell=1000>ic2:cell		Items that hold air without being fluid containers (IC2's Compressed Air Cell), for the container slots of the Scuba Gear and the compressor. One per line: <item>=<millibuckets>, optionally followed by ><empty item> for the item it leaves and that the compressor fills again. Items as in recipes.boat.motors: ic2:<IC2 item name>, item:<modid>:<item name>[:<damage>], ore:<Ore Dictionary name>, stack:<modid>:<registered stack name>. GregTech's air cells are fluid containers and need no entry. Needs a restart.

scuba.compressor.airPerFuelTick	int	10	0 to 1000	Millibuckets of air the furnace makes per tick of burning fuel: one coal (1600 ticks) makes 16000 with the defaults. 0 turns the furnace off.
scuba.compressor.fillPerTick	int	50	1 to 64000	Millibuckets per tick moved into the Scuba Gear in the compressor's slot (an empty gear fills in 6 seconds with the defaults).
scuba.compressor.intervalTicks	int	10	1 to 200	The compressor works once every this many ticks, doing the work of all those ticks at once.
scuba.compressor.needsOpenAir	boolean	true		The hand pump and the furnace make air only when the block above the compressor is air, so it is not an air source buried or under water. Air from pipes is taken anyway.

flamethrower.coneDegrees	double	25.0	5.0 to 90.0	Opening of the cone of flame in degrees, around the direction the wearer looks.
flamethrower.damage	double	2.0	0.0 to 40.0	Fire damage of one burst to each target in the cone (2 is one heart). Vanilla's half second of invulnerability after a hit means not every burst lands. Fire-immune mobs take none.
flamethrower.fireSeconds	int	5	0 to 60	Seconds every target in the cone keeps burning after a burst. 0 does not set targets on fire.
flamethrower.pvp	boolean	false		Let the flame hurt and burn other players. Even when true, the server's pvp setting and scoreboard teams still apply. Animals the wearer owns are never hurt.
flamethrower.ignitesBlocks	boolean	false		Let each burst set fire to the side of the block it hits, like flint and steel. The fire is vanilla fire, so it spreads and burns as usual. It respects spawn protection, adventure mode and protection mods that cancel block placing.
flamethrower.pilotFuelPerMinute	int	0	0 to 6000	Millibuckets of fuel the lit pilot burns per minute while the pack is worn, times the fuel's multiplier. 0 (the default) makes the pilot free.
flamethrower.sound	boolean	true		Play the vanilla ignite sound when the pilot is lit (the server sends it) and the vanilla fire sound while the nozzle fires (each client plays it). Set it the same on server and clients.

Fuels (fuels)

One list of liquid fuels for everything that burns them: the Copter Pack, the Flamethrower Pack, the boat motor and the Fuel Station. See Fluids and Hose.

Key	Type	Default	Range	What it does
fuels.list	string list	fuel=1.0, oil=1.5, bioethanol=1.2, biofuel=1.0, creosote=1.8, coal=0.8, biomass=1.5		Liquid fuels as fluidName=multiplier. The fuel cost of each user (copterpack.fuelPerTick...) is multiplied by it: higher burns faster. Only these fluids go into fuel tanks. Use the fluid names the mods register (BuildCraft oil and fuel, Forestry bioethanol and biomass, Railcraft creosote, Thermal Foundation coal, GregTech fuel (diesel), bioethanol and creosote); add lava=4.0, for example, to burn lava. Moved here from copterpack.fuels, keeping its value. Set it the same on server and clients. Needs a restart.

Fuel station (fuelstation)

The Fuel Station. The block is switched by enabled.fuelStation.

Key	Type	Default	Range	What it does
fuelstation.tankCapacity	int	16000	1000 to 64000	Capacity of the station's tank in millibuckets. Use the same value on server and clients. Lowering it does not delete fuel already stored above the new limit. Needs a restart.

Inflatable boat (inflatableboat)

The plain boat. The motor of the motorized one has its own section below.

Key	Type	Default	Range	What it does
inflatableboat.maxSpeed	double	0.35	0.07 to 2.0	Top speed in blocks per tick (the vanilla boat uses 0.35). The motorized boat without fuel, or with its motor off, uses it too.

Boat motor (inflatableboat.motor)

The outboard motor of the Motorized Inflatable Boat. It burns the fuels of fuels.list. Speeds are in blocks per tick. See Gear.

Key	Type	Default	Range	What it does
inflatableboat.motor.enabled	boolean	true		The motor of the Motorized Inflatable Boat. False: the motor is only a look, and the boat moves like the plain one.
inflatableboat.motor.mode	string	toggle	toggle, hold	toggle: the motor key (keys.boatMotorToggle, set it in Options > Controls) turns the motor on and off, and the boat goes ahead on its own while the pilot steers; holding back still brakes. hold: the motor pushes while the pilot holds the forward key. Either way it stops without fuel, when the pilot gets off and out of the water. Read on the server.
inflatableboat.motor.maxSpeed	double	0.6	0.05 to 2.0	Top speed while the motor runs, in blocks per tick (0.6 = 12 blocks per second; the boat without motor uses inflatableboat.maxSpeed). Use the same value on server and clients.
inflatableboat.motor.acceleration	double	2.0	1.0 to 10.0	How much faster than the plain boat the boat speeds up while the motor runs: 1.0 = as fast as the plain boat, 2.0 = twice as fast. Use the same value on server and clients.
inflatableboat.motor.fuelPerTick	int	1	0 to 100	Millibuckets of fuel per tick while the motor runs, before the fuel's own multiplier (fuels.list). With the defaults a full tank of fuel lasts 5 minutes. 0 makes the motor free (it still needs some fuel in the tank).
inflatableboat.motor.fuelIntervalTicks	int	10	1 to 200	Fuel is taken once every this many ticks of running: the cost of all those ticks at once.
inflatableboat.motor.tankCapacity	int	6000	1000 to 64000	Capacity of the motor's fuel tank in millibuckets. Use the same value on server and clients. Lowering it drops the fuel above the new limit when a boat is loaded or placed. Needs a restart.
inflatableboat.motor.outOfWaterTicks	int	10	1 to 200	The motor stops after the boat has been out of the water for this many ticks in a row (on land, or in the air over a wave or a drop).
inflatableboat.motor.sound	boolean	true		Sound of the boat motor, on the client: a looping putt-putt while the motor runs, a cord pull when it starts and a cough when it stops. It replaces the chat messages as the motor's notice. False: the motor is silent.
inflatableboat.motor.soundVolume	double	0.6	0.0 to 1.0	Volume of the boat motor's sounds, from 0.0 (silent) to 1.0, on the client. The running loop is a little quieter at low speed and louder at full speed.
inflatableboat.motor.messages	boolean	false		Chat messages about the boat motor (on, off, out of fuel, not on water), read on the server. Off by default: the sound is the notice. Turn it on for players who cannot hear.

Clockwork crossbow (crossbow)

A repeating crossbow fed with reusable Crossbow Magazines. The key keys.crossbowMode changes its mode; the other two modes have their own sections below. In repetition mode, hold right click to fire the magazine one bolt after another; when it is empty the next click puts in the first loaded magazine of your inventory, hotbar first, and the empty one comes back to the inventory, or drops at your feet when it is full. Sneak + right click swaps a partly used magazine, which comes back with the charges it has left. Ticks are 20 per second.

Key	Type	Default	Range	What it does
crossbow.shotDelayTicks	int	4	1 to 40	Pause between two bolts. Minecraft repeats a held right click every 4 ticks, so the real pause while holding is this value rounded up to a multiple of 4 (4 = 5 bolts a second, 5 to 8 = 2.5 a second).
crossbow.reloadTicks	int	30	0 to 200	Time to put a magazine into the crossbow, during which the crossbow does not fire.
crossbow.boltVelocity	double	3.0	0.5 to 6.0	Bolt speed in blocks per tick when it leaves the crossbow (a fully drawn bow shoots at 3). Faster bolts fly flatter and further.
crossbow.boltDamage	double	4.0	0.0 to 100.0	Damage of a bolt fired from a magazine of arrows as it leaves the crossbow, in half hearts (a fully drawn bow does 6 to 10). Crossbow Bolts multiply it by crossbow.ammo.boltDamageMultiplier. It drops a little with distance as the bolt slows down.
crossbow.ignoreHurtCooldown	boolean	true		Bolts ignore the short invulnerability a mob gets after a hit, so every bolt of a burst lands. When false about half of a fast burst bounces off the same target.
crossbow.boltsRecoverable	boolean	false		Bolts stuck in a block can be picked up as arrows. Off by default: a charge of the magazine is spent ammunition.
crossbow.durability	int	0	0 to 100000	Bolts the crossbow fires before it breaks. 0 means it never breaks.

Crossbow Magazine (crossbow.magazine)

The Crossbow Magazine is reusable: you load it by hand with ammunition and the crossbow gives it back empty.

Key	Type	Default	Range	What it does
crossbow.magazine.capacity	int	6	1 to 24	Charges a full Crossbow Magazine holds, and bolts the crossbow fires from it.
crossbow.magazine.loadTicksPerCharge	int	4	0 to 100	Pause between two charges while loading a magazine with a held right click (a held click repeats every 4 ticks). 0 loads the whole magazine with one click.
crossbow.magazine.reloadRecipe	boolean	true		Shapeless recipe: a magazine and up to its free room of ammunition of one kind (the kind it already holds) make the magazine loaded with them. Needs a restart.
crossbow.magazine.legacyRecipe	boolean	true		Keep the quick recipe (6 arrows, an iron ingot, 2 sticks): it makes a magazine already loaded with 6 arrows. The empty magazine has its own recipe (an iron ingot, 2 sticks and a string). Needs a restart.

Ammunition (crossbow.ammo)

What the Crossbow Magazine is loaded with. Bolts fired from a magazine of Crossbow Bolts hit harder than those from a magazine of arrows.

Key	Type	Default	Range	What it does
crossbow.ammo.list	string list	adventurebackpack:bolt, minecraft:arrow		Items a magazine can be loaded with, as modid:itemName (any damage value). An empty magazine takes the first ammunition found in the inventory (hotbar first); a loaded one only its own kind. Unknown names are ignored. Same on server and clients.
crossbow.ammo.boltDamageMultiplier	double	1.5	0.1 to 10.0	Damage of bolts fired from a magazine of Crossbow Bolts, as a multiple of crossbow.boltDamage and crossbow.sniper.boltDamage. Other ammunition does the base damage.

Grappling hook (crossbow.grapple)

The second mode of the crossbow: right click shoots a hook that catches a block and pulls the player to it. Speeds are in blocks per tick (20 ticks a second).

Key	Type	Default	Range	What it does
crossbow.grapple.enabled	boolean	true		The grappling hook mode. When false the mode is skipped and a crossbow left in it shoots bolts.
crossbow.grapple.maxDistance	double	32.0	4.0 to 64.0	Range of the hook in blocks. A hook that reaches it without catching comes back.
crossbow.grapple.hookSpeed	double	2.5	0.5 to 5.0	Speed of the flying hook, in blocks per tick. It flies straight, without gravity.
crossbow.grapple.pullSpeed	double	0.8	0.1 to 3.0	Speed at which the hook pulls the player, in blocks per tick (sprinting is about 0.28).
crossbow.grapple.releaseDistance	double	1.5	0.5 to 4.0	The hook lets go when the player's body is this close to the anchor, in blocks.
crossbow.grapple.maxPullTicks	int	60	10 to 200	Longest pull; the hook lets go after it (for example when the player is stuck under a ledge). On a server with allow-flight=false keep it under 80, or a long upward pull can kick the player for flying.
crossbow.grapple.cooldownTicks	int	20	0 to 200	Wait after firing the hook before the crossbow can fire or reload again.
crossbow.grapple.chargesPerShot	int	1	0 to 24	Bolts from the magazine a hook shot takes. 0 makes it free; more than a full magazine counts as a full magazine.
crossbow.grapple.noFallDamage	boolean	true		The pull never causes fall damage: the fall distance is reset while pulling and when the hook lets go. A fall after letting go counts from there.

Sniper mode (crossbow.sniper)

The third mode: with the bipod down (sneaking, standing still on the ground) the crossbow fires one strong, straight bolt. With the bipod folded it fires normal bolts.

Key	Type	Default	Range	What it does
crossbow.sniper.enabled	boolean	true		The sniper mode. When false the mode is skipped and a crossbow left in it shoots normal bolts.
crossbow.sniper.boltDamage	double	12.0	0.0 to 100.0	Damage of a sniper bolt as it leaves the crossbow, in half hearts. It drops a little with distance as the bolt slows down.
crossbow.sniper.boltVelocity	double	5.0	0.5 to 8.0	Speed of a sniper bolt in blocks per tick. Faster bolts fly flatter and further.
crossbow.sniper.shotDelayTicks	int	30	4 to 200	Pause after a sniper shot. A held right click repeats every 4 ticks, so the real pause is this value rounded up to a multiple of 4.
crossbow.sniper.stillTolerance	double	0.02	0.001 to 0.2	Horizontal movement in blocks per tick under which the player counts as still (sneak walking is about 0.065).
crossbow.sniper.zoom	double	0.35	0.1 to 1.0	Client only: field of view multiplier while the bipod is down. 1 = no zoom, 0.35 = about three times closer.

Piston boots (pistonboots)

Key	Type	Default	Range	What it does
pistonboots.onlyWhileSprinting	boolean	true		Step up full blocks only while sprinting, so walking up to a block does not climb it. False steps up at any pace while the boots are on. The sprint speed is only given while sprinting either way.
pistonboots.stepHeight	double	1.001	0.5 to 3.0	Step height while the boots step up (vanilla is 0.5).
pistonboots.sprintSpeed	boolean	true		Give Speed I while sprinting.
pistonboots.safeFallDistance	int	8	0 to 256	Falls shorter than this many blocks do no damage. 0 turns it off.

Campfire cooking (campfire.cooking)

Right click the campfire with a raw item to cook it. The campfire block, its recipe and its use as a respawn point do not depend on these keys; enabled.campfire only turns the cooking on or off. Ticks are 20 per second.

Key	Type	Default	Range	What it does
campfire.cooking.enabled	boolean	true		Cook items by right clicking the campfire with them.
campfire.cooking.ticksPerItem	int	200	1 to 12000	Time to cook one item (the furnace takes 200).
campfire.cooking.onlyFood	boolean	true		Only cook items whose furnace result is food. False takes any furnace recipe (ores, sand, logs...).
campfire.cooking.maxPerUse	int	8	1 to 64	Most items the campfire holds at once; a right click puts on as many as fit, the rest stays in the hand.
campfire.cooking.returnRange	double	4.0	0.0 to 16.0	Distance in blocks within which the cooked items go straight into the inventory of the player who put them on the fire. Farther away, or with 0, they pop out on top of the campfire.

Sleeping bag (sleepingbag)

Key	Type	Default	Range	What it does
sleepingbag.placeable	boolean	true		Right click the top of a block with the Sleeping Bag item to lay it on the ground as a bed, without a backpack. Breaking it gives the item back; sneak + right click rolls it up into the inventory.
sleepingbag.setsSpawn	boolean	true		Sleeping in a sleeping bag (placed on its own or from a backpack) moves the player's spawn point there, like a bed. When false the player keeps the spawn point they had.

Display (render)

Client only: how the mod draws things. The server ignores this section.

Key	Type	Default	Range	What it does
render.backpackOnPlayer	boolean	true		Draw the worn backpack on the player. Turn it off with mods that already draw the player's back, like Smart Moving.
render.tankRenderType	int	3	1 to 3	How fluids are drawn in the tanks of the backpack window: style 1, 2 or 3.
render.tankHoverText	boolean	false		Show the tank contents as hovering text instead of under the tanks.
render.statusOverlay	boolean	true		Show the player's potion effects on screen.
render.scubaBubbleTicks	int	10	1 to 200	Ticks between two puffs of bubbles from the mask of a player breathing from the Scuba Gear.
render.flamethrowerParticles	int	6	0 to 30	Flame particles drawn along the cone for each burst of a Flamethrower (smoke comes with every second burst). 0 draws none.
render.wearableOverlay	boolean	true		Show the overlays of the worn backpack, copter pack or jetpack on screen, and the fuel tank of the motorized boat the player rides.
render.boatSmokeTicks	int	8	0 to 200	The running motor of the motorized boat puffs smoke once every this many ticks. 0 = no smoke.

Keys (keys)

Client only. Default keys, as LWJGL key codes (B is 48, N is 49; see the LWJGL Keyboard class). They are only defaults: once you change a key in Options > Controls, Minecraft keeps your choice.

Key	Type	Default	Range	What it does
keys.openBackpack	int	48	0 to 255	Default key that opens the worn backpack, copter pack or jetpack (48 = B). Needs a restart.
keys.toggle	int	49	0 to 255	Default key that switches the hose tank and drives the worn copter pack or jetpack (49 = N). With the copter pack, the key changes its mode (normal or hover) and Sneak + the key turns it on or off; with the jetpack, Sneak + the key turns it on or off; Sneak + N lights the Flamethrower Pack. Needs a restart.
keys.crossbowMode	int	47	0 to 255	Default key that changes the firing mode of the held Clockwork Crossbow (47 = V). Needs a restart.
keys.toggleAbilities	int	0	0 to 255	Default key that turns the abilities of the worn backpack off and on, for this player only (night vision, water breathing, fire resistance, milk...). 0 = not bound: pick one in Options > Controls. Needs a restart.
keys.boatMotorToggle	int	0	0 to 255	Default key that turns the motor of the Motorized Inflatable Boat on and off while riding it (inflatableboat.motor.mode toggle). 0 = not bound: pick one in Options > Controls. Needs a restart.

Tool swapping keys (keys.toolcycle)

Client only. Swapping the held tool with the backpack's tool slots, and changing the hose mode. The keys themselves are changed in Options > Controls.

Key	Type	Default	Range	What it does
keys.toolcycle.enabled	boolean	true		Swap the held tool with the backpack's tool slots, and change the hose mode, from the keyboard or mouse wheel. False turns both off, so the wheel always scrolls the hotbar.
keys.toolcycle.mode	string	both	wheel, keys, both	wheel: hold the modifier key and turn the mouse wheel. keys: only the next and previous tool keys. both: either one.
keys.toolcycle.invertWheel	boolean	false		Turn the mouse wheel the other way to cycle.
keys.toolcycle.modifierKey	int	0	0 to 255	Default key to hold while turning the mouse wheel. 0 means the sneak key (Left Shift by default), because a separate binding on the same key as sneak would stop one of the two from working in 1.7.10. Needs a restart.
keys.toolcycle.nextToolKey	int	0	0 to 255	Default key for the next tool. 0 means not bound. Needs a restart.
keys.toolcycle.previousToolKey	int	0	0 to 255	Default key for the previous tool. 0 means not bound. Needs a restart.

Backpacks in the world (worldgen)

Key	Type	Default	Range	What it does
worldgen.bonusChestBackpack	boolean	false		Put a Standard Adventure Backpack in the bonus chest.
worldgen.pigmanBackpacks	boolean	false		Let Pigman Backpacks appear in dungeon loot and villager trades.

Extra recipes (recipes)

The saddle recipe, and the recipes that change with the mods that are loaded: the Inflatable Boat, the Fuel Station, the Flamethrower Pack and the Flamethrower. The Diving Mask and the Pyro Mask follow the rubber setting of the boat, recipes.boat.mode and recipes.boat.rubber. The list entries are read once when the game starts, after every mod has registered its items. See Gear, Scuba Gear, Flamethrower and Fuel Station.

Key	Type	Default	Range	What it does
recipes.saddle	boolean	true		Add a crafting recipe for the saddle.
recipes.boat.mode	string	auto		vanilla: only the vanilla recipes. auto: the vanilla recipes, plus a rubber or motor variant when a loaded mod provides rubber or an electric motor. technical: the rubber or motor variant replaces the vanilla recipe of each part a loaded mod provides; a part no loaded mod provides keeps its vanilla recipe. Values: auto, vanilla, technical. Needs a restart.
recipes.boat.rubber	string list	itemRubber, plateRubber, ingotRubber		Ore Dictionary names of rubber (IC2 itemRubber, GregTech plateRubber and ingotRubber...). Each one some loaded mod provides gets its own chamber recipe (three rubber, two chambers). Needs a restart.
recipes.boat.motors	string list	ic2:elemotor, item:gregtech:gt.metaitem.01:32600, ore:craftingElectricMotor, stack:ThermalExpansion:powerCoilGold		Electric motors for the motorized boat, each one found gets its own recipe (boat + motor + Hydro Blades). Entries: ic2:<IC2 item name> (IC2 API), item:<modid>:<item name>[:<damage>], ore:<Ore Dictionary name>, stack:<modid>:<registered stack name>. Needs a restart.
recipes.fuelstation.mode	string	auto		vanilla: only the iron ingot recipe. auto: the iron ingot recipe, plus one with plates for each plate a loaded mod provides. technical: the plate recipes replace the iron ingot one when a loaded mod provides a plate; without plates the iron ingot recipe stays. Values: auto, vanilla, technical. Needs a restart.
recipes.fuelstation.plates	string list	plateSteel, plateIron		Ore Dictionary names of the metal plates for the technical recipe (GregTech, IC2, Thermal Foundation, Railcraft plateSteel and plateIron...). Each one some loaded mod provides gets its own recipe. Needs a restart.
recipes.flamethrower.mode	string	auto		vanilla: only the iron ingot recipes. auto: the iron ingot recipes, plus ones with plates for each plate a loaded mod provides. technical: the plate recipes replace the iron ingot ones when a loaded mod provides a plate; without plates the iron ingot recipes stay. Values: auto, vanilla, technical. Needs a restart.
recipes.flamethrower.plates	string list	plateSteel, plateIron		Ore Dictionary names of the metal plates for the technical recipes of the pack and the nozzle (GregTech, IC2, Thermal Foundation, Railcraft plateSteel and plateIron...). Each one some loaded mod provides gets its own recipe. Needs a restart.

Small tweaks (tweaks)

Fixes and behaviours that are not tied to one item.

Key	Type	Default	Range	What it does
tweaks.fixVanillaLead	boolean	true		Mobs on a lead held by a player take no fall damage unless they fall fast.
tweaks.namedHorsesFollowOwner	boolean	true		Tamed horses with a name tag follow their owner.

Tool slots (tweaks.toolcycle)

Which items may go into the two tool slots of the backpack, by hand or with the tool swap. Set it the same on the server and on every client.

Key	Type	Default	Range	What it does
tweaks.toolcycle.mode	string	none	none, whitelist, blacklist	Which items may go into the backpack's two tool slots, by hand or with the tool cycle. none: the built-in rules (vanilla tools, shears, hoes, fishing rods, flint and steel, and tools of Tinkers' Construct, BuildCraft, IndustrialCraft and Thermal Expansion). whitelist: only the items on the list. blacklist: the built-in rules minus the items on the list. Stackable items, hoses and backpacks never go in. Set it the same on server and clients.
tweaks.toolcycle.list	string list	empty		Items for the whitelist or blacklist mode, one per line, as registry names: modid:name (minecraft:shears, TConstruct:pickaxe; the names /give takes), or modid:* for every item of a mod. A name without a mod id means minecraft:. Case does not matter. A blacklisted bow also stops the Skeleton Backpack from cycling it.

Grave mods (compat.graves)

Acts only when OpenBlocks or GraveStone is loaded.

Key	Type	Default	Range	What it does
compat.graves.enabled	boolean	true		Send the worn wearable to the grave of OpenBlocks or GraveStone when one of them is loaded. When false, backpack.placeOnDeath decides as if no grave mod were there.

Baubles (compat.baubles)

Acts only when Baubles or Baubles Expanded is loaded.

Key	Type	Default	Range	What it does
compat.baubles.enabled	boolean	true		Let the Adventure Backpack go into a bauble slot and work from there. When false the backpack does not fit a bauble slot and one already there does nothing. The Baubles Expanded back slot exists anyway (so client and server always match); its layout can be changed in the Baubles Expanded config.

Checks the mod makes

Two combinations are fixed when the file is read: the Bat night vision length must be longer than its refresh threshold (if not, it is set to the threshold plus 100 ticks), and the steam spent per tick of thrust cannot be more than the steam tank holds.

Flight values before 1.0.0

Flying costs more in 1.0.0. These are the earlier values, for a pack that wants the old balance. With them the copter pack and the jetpack are still dearer than before in some modes: the climb is charged now, and the cost is paid for the whole interval.

Key	1.0.0 default	Earlier value
copterpack.fuelPerTick	2	1
copterpack.startFuel	100	0
copterpack.liftSpeed	0.15	0.18
copterpack.airControl	0.03	0.05
copterpack.maxAltitude	90	100
steamjetpack.steamPerTick	20	13

Not in the file

These are fixed on purpose: how much a backpack holds and how its slots are laid out (changing it would break saved backpacks), the boiler heat curve of the jetpack beyond its boiling point, the physics of the Inflatable Boat other than its top speed and its motor, the push strength of the copter rotor, the death placement search (12 blocks around, 6 up and down) and the reach of the sleeping bag button (8 blocks).
