Doors and Chests

Security Door and Blast Door

The Security Door is a powered door two blocks tall and one wide. The Blast Door is two by two, with heavier plating, and follows the same rules. Both open only for the access level you set.

Recipes:

Security Door         Blast Door
I R I                 B O B
I D I                 S O S
I I I                 B O B

I = iron ingot, R = redstone, D = iron door,
B = block of iron, O = obsidian, S = Security Door

Using a door

  • Use the door to open it, and use it again to close it. Anyone allowed to open it may close it.
  • An open door closes itself after 3 seconds by default (doorAutoCloseTicks, 0 keeps it open).
  • The door is only passable once it is fully open.
  • An unlinked door is public: anyone can open and close it.
  • When you are refused, the door flashes red, plays a short sound and the action bar says why.

Settings

Sneak and use the door to open "Who can open this door?" (OFFICER or higher).

  • Level ladder: the lowest level that opens the door. New doors start at MEMBER.
  • Keycard only: ignore membership; only a keycard at this level or higher opens it.
  • Opens while powered by redstone: shown only when the server allows door redstone. A powered door opens for anyone who can power it, so the screen warns you. Redstone never opens a door during a lockdown. Doors never emit redstone.
  • Power bar and status lines: linked or not, sealed by lockdown, unpowered.
  • Upgrades: two slots for Hardness and Open-Speed Modules.

Power

Doors store energy from Neroland Core's power system (or any compatible power mod). On NeoForge and Fabric every part of the door takes power; on Forge only the controller block does (the bottom block, or the bottom-left block of a blast door). A linked, closed door draws a little energy each tick, and each opening costs a bit more.

By default doors work without power (doorsRequirePower = false), which suits servers with no power mod. When the server requires power, an unpowered door opens only for its owners and operators.

Modules

  • Hardness Module: the door is harder to break and more blast resistant. Each module makes breaking slower. Blast resistance is capped by the server (doorMaxBlastResistance); nothing makes a door unbreakable.
  • Open-Speed Module: the door opens and closes faster.

Breaking

Anyone can break a door. That keeps bases raidable. If the person breaking it could not have opened it, the installation logs "Door forced", which alarms and the companion app can react to.

A wither or the ender dragon cannot destroy a door, chest, hub or any other NeroSecurity block. Raiding means mining or overloading, not summoning a boss.

During lockdown

A door of an installation in lockdown is sealed: only OWNER-level access opens it. See Lockdown.

Secure Chest

The Secure Chest has 27 slots and checks access when you open it.

I I I     I = iron ingot
I C I     C = chest
I I I
  • Use to open it. You need the chest's level (MEMBER by default), or a keycard when it is keycard-only. An unlinked secure chest behaves like a plain chest.
  • Access is checked again every tick while the chest is open, so a lockdown or a revoked card closes the screen straight away.
  • Sneak and use to open "Who can open this chest?" (OFFICER or higher): the level ladder, the keycard-only switch, and the automation line.
  • The chest has no comparator output, so its fill level stays private.
  • Anyone can break it. The contents always drop. A break by someone who could not open it is logged as "Chest forced".
  • Opening a chest and changing its contents are logged, without the items.

Automation

Hoppers, droppers and pipes count as automation. Each installation has one automation policy, set by an owner:

/nerosecurity automation <installation> off|member|officer

Automation acts as a player of that level. It can reach a chest only when:

  • the policy is not off,
  • the policy is at least the chest's level,
  • the chest is not keycard-only, and
  • the installation is not in lockdown.

New installations start with the server's default policy (chestAutomationDefault, off unless the server changed it). The chest screen shows whether automation is allowed and, if not, why.
