Lua triggers

[BlackMadd]

I'm trying to make an entity that I can control with lua. I have reached a road block though because I've never done this before :( My concept is to have one entity that I can spawn under different names (variables) and then modify them based on my map and players. What I am trying to achieve is to have an entity where a player walks into it and music plays, only to stop playing when the player leaves. I'm trying to incorporate my entity with [url]http://wiki.garrysmod.com/page/ENTITY/StartTouch[/url], [url]http://wiki.garrysmod.com/page/ENTITY/EndTouch[/url], [url]http://wiki.garrysmod.com/page/Category:IGModAudioChannel[/url] and various other entity specific functions to set it's location in the world.

My code as follows so far.

[B]The Entity[/B]

AddCSLuaFile() -- Why? Because nothing was explained, tutorials just said do it...

ENT.Type = 'anim' -- I still dont understand what these do :/
ENT.Base = 'base_gmodentity' -- Had to move base_gmodentity.lua from sandbox for compatibility.

ENT.PrintName = 'Zoning Music Base'
ENT.Author = 'Renamon Toast Crunch'
ENT.Purpose = 'Base entity for dynamic zoned music'
ENT.Instructions = 'Spawn and modify with lua'

ENT.Spawnable = false -- Nope
ENT.AdminSpawnable = false -- We want to spawn aand modify within lua only and not be controlled outside of the files.

function ENT:Initialize()  
    self:SetSolid( 0 ) -- Not Solid
    self:SetCollisionBoundsWS(Vector(0,0,0),Vector(0,0,0)) -- This is in the void.
    self:SetTrigger(true) -- So self is editable with lua.
end

function ENT:StartTouch()
end

function ENT:StopTouch()
end

[B]Serverside File[/B]

-- This is a serverside file!

/*
3D H/W Reference
( Vector( -1122.997925, 2017.903564, -2951.961670 ), Vector( -864.203491, 1775.536865, -3198.830566 )) -- Zone: Secret Room
( Vector( -804.779541, 698.597168, -2244.161865 ), Vector( -1250.074219, 1865.446411, -2555.334717 ))  -- Zone: Spawn Room
( Vector( -2319.035645, 4598.020020, -5.790947 ), Vector( -5994.073242, -485.654572, -3550.934326 )) -- Zone: Tutorial Island
*/

timer.Simple( 3, function() --Create the map entitys 3 seconds after gamemode loads to prevent errors.

	MsgC( Color( 255, 0, 255 ), "Varsgroth: ",Color( 0, 255, 0 ),"Zoning Check!\n")

	local zcc = ents.Create('dyn_music')
		zcc:SetPos(Vector( 413.939758, 1272.408325, -1966.252075 )) -- Vector position in the center of the CCreation room.
		zcc:SetCollisionBoundsWS(Vector( -111.968750, 1647.968750, -1967.854248 ), Vector( 621.744141, 912.075867, -1562.446289 )) -- 3D W/H of ZCC.
		zcc:Spawn()
		zcc:EmitSound( 'HL1/fvox/activated.wav',100,100 ) -- Emitting sound just to make sure it's actually where it's supposed to be.
		print('Success!')

end)

The above code works... kinda but what I cant figure out is how to do StartTouch and EndTouch from the serverside file. I have only begun testing via one spawned entity (in this case named zcc) but will end up spawning 3 others under the names zsr, zti, and zspr.

You need to move StartTouch and EndTouch in to your init.lua, they are serverside, and you can then send a net message on StartTouch to the client telling them to play the music, then store the music channel in a variable clientside, then when EndTouch is called send a net message telling the music to stop, then call stop on the channel variable you made earlier.

use a brush ent, not an anim ent

Thanks, I was wondering what to put for ENT.Type, I can't seem to find anything about the types though like a list of the types and what they are each for :/

Thanks for the help, I'll try that soon.

	zcc = ents.Create('dyn_music')
		if (  !IsValid( dyn_music ) ) then return end
		zcc:SetPos(Vector( 256,1280,-1824 )) -- Vector position in the center of the CCreation room.
		zcc:SetCollisionBoundsWS(Vector( -128,1664,-2144 ), Vector( 640,896,-1536 )) -- 3D W/H of ZCC.
		zcc:Spawn()
		zcc:EmitSound( 'HL1/fvox/boop.wav',100,100 ) -- Emitting sound just to make sure it's actually where it's supposed to be.
		print('Success!')

	function zcc:StartTouch(hitent)
		if ( hitEnt:IsValid() and hitEnt:IsPlayer() ) then zcc:EmitSound( 'HL1/fvox/activated.wav',100,100 ) end
	end

	function zcc:StopTouch(hitent)
		if ( hitEnt:IsValid() and hitEnt:IsPlayer() ) then zcc:EmitSound( 'HL1/fvox/deactivated.wav',100,100 ) end
	end

end)

My SetPos function doesn't seem to work, the entity is just spawned to 0,0,0 :(

1. Use this to spawn them: (reference: [url]http://facepunch.com/showthread.php?t=1408703[/url] )
[LUA]
hook.Add("InitPostEntity", "Spawn <entity name> after everything initialized", function() -- Don't forget to add the entity's name!

local Spawns = {
{
pos = Vector( 256, 1280, -1824 ),
ang = Angle( 0, 0, 0 )
} -- I think you know how to add more items :P
}

for _, v in pairs(Spawns) do
local the_ent = ents.Create( 'dyn_music' )
the_ent:SetPos(v.pos)
the_ent:SetAngles(v.ang)
the_ent:SetModel( "<model>" ) -- Don't forget to change this!
the_ent:Spawn()
the_ent = nil
end
end)
[/LUA]

2. For the StartTouch/EndTouch hooks, you'd need to indentify whether the sound had stopped playing so you could re-start playing it(if you need some reference, you can use the WireMod's Sound Player entity)

3. So the StartTouch/EndTouch hooks work, you have to use them on the Entity's files, and define them as an Entiy's function, like:[LUA]ENT:StartTouch()[/LUA] or [LUA]ENT:EndTouch()[/LUA]
