Overview

Contribute to Swamp Cinema here! How to:

'Fork' this repo. This creates a copy of it you have edit permissions of.
Clone your forked repo into garrysmod/addons (so it creates garrysmod/addons/contrib), edit it, and push it back. You'll need the GitHub desktop or commandline client. Look up GitHub tutorials for that.
For clientside work, check out the devtools which allow you to work on the actual server environment.
Make a pull request on this repo. Use the 'compare across forks' link to request to merge your changes on your forked repo to this repo. Accepted changes are installed automatically, although new files won't run until after a server reset.
Minor, single-file changes can just be done in the web browser by clicking the pencil icon.

All models/materials/sounds in this repository will be automatically uploaded to our workshop addons, so don't worry about that.

Code

Please submit code that is clean and concise. You may want to run it through glualint. Do a good job!
Make your code compatible with our loading system.
Try to put cinema-specific code in gamemodes/cinema/ and generic (cross-server) code in lua/. Both folders are loaded using our loading system.

Code Style

Name stuff like this. A lot of current code doesn't conform, but this is the style:

local my_var = 1
local function my_func()
tab.data_member = 1
GlobalVariable = 1
function GlobalFunc()
function tab:FunctionMember() -- use this naming for callable tables as well
panel.ChildPanel = ui.Label()
CONSTANT_VALUE = 1

Never use capital letters when naming local vars/functions

API

gm = engine.ActiveGamemode()

Shorthand for gamemode name
file: lua/autorun/swamp.lua

function FindLocation(ent_or_pos)

Global function to compute a location ID (avoid this, it doesn't cache)
file: lua/cinema/location/sh_location.lua

function Player:ExtEmitSound(sound, options)

Will probably be deprecated
possible options:
pitch
crouchpitch
level
volume
channel
ent: emit from this ent instead of player
shared: emit on client without networking, assuming called in shared function
speech: move player lips (time to move lips, or auto if < 0)
file: lua/cinema/sound/sh_extsound.lua (hidden)

function Entity:IsProtected(att)

If we are "protected" from this attacker by theater protection. att doesn't need to be passed, it's only used to let theater owners override protection and prevent killing out of a protected area.
file: lua/cinema/theater/sh_protection.lua (hidden)

function Player:GetRank()

Numeric player ranking (all players are zero, staff are 1+)
file: lua/swamp/admin/sh_init.lua (hidden)

function Player:IsStaff()

Boolean
file: lua/swamp/admin/sh_init.lua (hidden)

function Player:IsTyping()

Bool (typing a chat message)
file: lua/swamp/chat/sh_swampchat.lua (hidden)

Font = memo(function(setting_str)

Generates a font quickly. Caches so it can be used in paint hooks.
Example input: draw.DrawText("based", Font.Arial24)
file: lua/swamp/cl_font.lua

function GetTextSize(font, text)

surface.GetTextSize with cached result
file: lua/swamp/cl_font.lua

function Player:IsAFK()

Boolean
file: lua/swamp/clientcheck/sh_afk_detect.lua (hidden)

function Player:IsActive()

Boolean, NOT AFK and NOT BOT
file: lua/swamp/clientcheck/sh_afk_detect.lua (hidden)

function bench(func)

Prints how long it takes to run a function, averaging over a large number of samples with minimal overhead
file: lua/swamp/dev/sh_bench.lua

function Ply(name)

For hacking/debugging. FindSinglePlayer but just returns nil if matches multiple.
file: lua/swamp/dev/sh_util.lua

Me (global variable)

Use this global instead of LocalPlayer()
It will be either nil or a valid entity. Don't write if IsValid(Me)... , just write if Me...
file: lua/swamp/extensions/cl_me.lua

function MeOnValid(func)

Call the function when Me becomes valid
file: lua/swamp/extensions/cl_me.lua

function cam.Culled3D2D(pos, ang, scale, callback)

Runs cam.Start3D2D(pos, ang, scale) callback() cam.End3D2D() but only if the user is in front of the "screen" so they can see it.
file: lua/swamp/extensions/cl_render_extension.lua

function render.DrawingScreen()

Bool if we are currently drawing to the screen.
file: lua/swamp/extensions/cl_render_extension.lua

function render.WithColorModulation(r, g, b, callback)

file: lua/swamp/extensions/cl_render_extension.lua

function DFrame:CloseOnEscape()

Call this to make a DFrame dissapear if the user hits escape
file: lua/swamp/extensions/cl_vgui_function.lua

function vgui(classname, parent (optional), constructor)

This defines the function vgui(classname, parent (optional), constructor) which creates and returns a panel.

The parent should only be passed when creating a root element (eg. a DFrame) which need a parent.
Child elements should be constructed using vgui() from within the parent's constructor, and their parent will be set automatically.

This is helpful for creating complex guis as the hierarchy of the layout is clearly reflected in the code structure.

Example: (a better example is in the file)\

vgui("Panel", function(p)\
   -- p is the panel, set it up here\
   vgui("DLabel", function(p)\
       -- p is the label here\
   end)\
end)\

file: lua/swamp/extensions/cl_vgui_function.lua

function Anim(init, force, callback)

Makes an "anim" which smoothly interpolates a value
init = default value
force = acceleration towards target value
callback runs when value changes (return true to stop updating, but this happens automatically when target is reached)
returned table has functions __call() to get the current value, SetTarget(value) to set a target, SetInstant(value) to jump and set velocity to zero
file: lua/swamp/extensions/sh_anim.lua (hidden)

function AnimValue(subject, key, init_or_force, force)

Anim which will set a named property on a subject (entity or panel)
The value is placed at ent.Key and the anim is at ent.KeyAnim
file: lua/swamp/extensions/sh_anim.lua (hidden)

function Entity:TimerCreate(identifier, delay, repetitions, callback)

A timer which will only call the callback (with the entity passed as the argument) if the ent is still valid
file: lua/swamp/extensions/sh_ent_timer.lua

function Entity:TimerSimple(delay, callback)

A timer which will only call the callback (with the entity passed as the argument) if the ent is still valid
file: lua/swamp/extensions/sh_ent_timer.lua

Ents (global variable)

A global cache of all entities, in subtables divided by classname.
Works on client and server. Much, much faster than ents.FindByClass or even player.GetAll
Each subtable is ordered and will never be nil even if no entities were created.
To use it try something like this: for i,v in ipairs(Ents.prop_physics) do ...
file: lua/swamp/extensions/sh_ents_cache.lua

ply.NWP = {}

NWP="Networked Private"
A table on each player. Values written on server will automatically be replicated to that client. Won't be sent to other players. Read-only on client, read-write on server.
file: lua/swamp/extensions/sh_nwprivate.lua

function Entity:IsHuman()

IsPlayer and not IsBot
file: lua/swamp/extensions/sh_player_extension.lua

file: lua/swamp/extensions/sh_player_extension.lua

function FindSinglePlayer(name, exact_overrides_multiple)

Find a player whose name contains some text. If it finds exactly one matching player, returns that player. Otherwise, returns the number of found players (0 or >=2). To use this check isnumber() on the return.
file: lua/swamp/extensions/sh_playerbyname.lua

function string.FormatSeconds(sec)

Turns a number of seconds into a string like hh:mm:ss or mm:ss
file: lua/swamp/extensions/sh_string.lua

function ShowMotd(url)

Pop up the MOTD browser thing with this URL
file: lua/swamp/misc/cl_motd.lua

function Player:Notify(...)

Show a notification (bottow center screen popup). OK to call on invalid players (does nothing).
file: lua/swamp/misc/sh_notify.lua

function Player:TrueName()

Return player's actual Steam name without any filters (eg removing swamp.sv). All default name functions have filters.
file: lua/swamp/misc/sh_player_name_filter.lua

function player.GetBySteamID(id)

Unlike the built-in function, this (along with player.GetBySteamID64 and player.GetByAccountID) is fast.
file: lua/swamp/misc/sh_playerbysteamid.lua

function Player:GetTitle()

Get current title string or ""
file: lua/swamp/misc/sh_titles.lua

function Player:RateLimit(name, interval, burst)

Rate limiter for net recievers and commands and whatnot. Interval is how many seconds between each action. Burst is how many we can do fast (default 1).
The function returns TRUE if the action should be blocked, FALSE if it should be ALLOWED. So do like if ply:RateLimit("thing", 1, 1) then return end to rate limit everything after it.
Call it with no arguments to use a default reasonable value for clickable actions or whatever.
file: lua/swamp/misc/sv_swamp_misc.lua (hidden)

function Entity:IsPony()

Boolean, mostly for players
file: lua/swamp/pony/sh_init.lua

function basememo(func, params)

Returns a table such that when indexing the table, if the value doesn't exist, the constructor will be called with the key to initialize it.

print(a[2][3]) --prints 6
If the function returns nil, nothing will be stored, and the second return value will be returned by the indexing.
params are extra things to put in the metatable (eg __mode), or index 1 can be a default initialization for the table

file: lua/swamp/webmaterials/cl_webmaterials.lua (hidden)

function RenderTarget(args)

Like CreateRenderTargetEx, but the args are a table with good defaults, you don't need a name, and if the ITexture gets garbage collected it can reuse the rendertarget for another call (since you can't delete RTs)

function DFrame:CloseOnEscape()

Call this to make a DFrame dissapear if the user hits escape
file: repos/contrib/lua/swamp/extensions/cl_vgui_function.lua (hidden)

function vgui(classname, parent (optional), constructor)

This defines the function vgui(classname, parent (optional), constructor) which creates and returns a panel.

The parent should only be passed when creating a root element (eg. a DFrame) which need a parent.
Child elements should be constructed using vgui() from within the parent's constructor, and their parent will be set automatically.

This is helpful for creating complex guis as the hierarchy of the layout is clearly reflected in the code structure.

Example: (a better example is in the file)\

vgui("Panel", function(p)\
   -- p is the panel, set it up here\
   vgui("DLabel", function(p)\
       -- p is the label here\
   end)\
end)\

__index = function(tab, key)
local d = constructor(key)
tab[key] = d

print(a[2][3]) --prints 6
If the function returns nil, nothing will be stored, and the second return value will be returned by the indexing.
params are extra things to put in the metatable (eg __mode), or index 1 can be a default initialization for the table

function weakref(value)

weak reference, call it to get the thing or nil if its gone
file: repos/contrib/lua/swamp/sh_init.lua (hidden)
