How to combine a map trigger brush with a gamemode?

Garry's Mod coding
#1

I’m attempting to allow the map to interact with the gamemode by placing a trigger brush in the map that is tied to an entity as “trigger_playermovement” with the name “checkpoint_00”.
Visual Reference: http://gyazo.com/5dd7d4be7b9ce86629973d9830faf629
Now in the gamemode’s code I added this bit to interact with the trigger brush:

init.lua


function ENT:Touch("checkpoint_00") 
	LocalPlayer():ChatPrint("TRIGGER!")
end

However as soon as I launch the map I get this error:


[ERROR] gamemodes/skillrace/gamemode/init.lua:19: <name> or '...' expected near '"checkpoint_00"'
  1. unknown - gamemodes/skillrace/gamemode/init.lua:0

I see it asks for a name, but I thought “checkpoint_00” would be the correct name.
Could somebody explain to me what I’m doing wrong here?

Thanks in advance! <3

I hvae no idea what you were trying to do, but:
a) You should read wiki
b) Here’s working code


function ENT:Touch( ent )
    if ( ent:IsPlayer() ) then ent:ChatPrint("TRIGGER!") end
end

By the way, you should put this into your trigger_playermovement entity, not gamemode.
