How does CustomEntityName:IsBLAHing thing work?

[RonanZer0]

This is kinda hard to explain. Various mods have things like ent:isRolling (just an example). how do you define things like that? I just don't know what it is actually called or what it can do. Like I wanted to do CustomDoor:IsBreaching or something but I dunno how

Its just a function name so you can easily tell what it returns.

function IsTraitor(ply)
if ply:GetRole() == ROLE_TRAITOR then
return true
else
return false
end
end

No...

What you're looking for is something like this.

[LUA]

local theMeta = FindMetaTable("Player")

function theMeta:AddPoints( num )
self.points = self.points + num
end

[/LUA]

You refer to the entity types metatable and add a function to it.
'self' in the function is the entity you are calling the function on.

There's no need of go into Metatable for add custom methods to entities

[lua]
--[[
:Entity code:
--]]

//An entity function that already exists
function ENT:Use()
//When player uses the entity, this call our custom method and uses an argument
self:SetFire(math.random(50))
end

//Custom method with a random name, with an argument if we need it
function ENT:SetFire(arg)
self:Ignite(arg)
end

[/lua]

If you want to do it inside an entity you've made, it's as simple as defining a function inside it:
[lua]
function ENT:SetTargetOwner( plyr )
self.TargetOwner = plyr
end
function ENT:GetTargetOwner( plyr )
return self.TargetOwner
end
[/lua]
Just an excerpt from a decoy or something. If you want to call it it's as simple as sticking the entity instance in a variable (e.g. from findbyclass) and calling the function on it
[lua]
local myEntity = someMethodOfGettingTheEntity()
myEntity:SetTargetOwner( somePlayer )
myEntity:GetTargetOwner()
[/lua]
Would return the somePlayer if it was set.

Due to these several mixed posts it's clear you aren't very clear, so I may not be what you're looking for.

Exacatly what I'm talking about. Like what is GetRole, how do you make it? Something like that

[zerf]

Oh, if what you're asking for is an extension to an object (player, for :GetRole()) you do it from a metatable like Pablo said. If it's your entity use what gonz or I posted.
