Creating a metatable for a specific entity class

[c👌de_g🎷]

Is it possible to have a metatable that inherits from the base entity and has specific functions for a class? Or do I just have to have an Entity parameter in my metatable?

I think you can do this by overriding __index or something. I was thinking about doing this for some methods that only work for specific classes.

[Kogitsune]

t = setmetatable( definition, { __index = entity meta table } )

[QUOTE=Kogitsune;49613558]

t = setmetatable( definition, { __index = entity meta table } )

[/QUOTE]

And would writing new functions to that metatable write it to the BaseEntity table as well, or just that specific object? I don't want to add the functions for ALL entities

[Kogitsune]

It should default to definition - you'd have to set __newindex to the entity meta to cause that.

Thanks!

local SMOKE = {}
local ENTITY = debug.getregistry().Entity

-- Inherit base entity functions
function SMOKE.__index(t, k)
	local val = rawget(t, k) or rawget(SMOKE, k) or ENTITY[k]
	
	return isfunction(val) and function(_, ...) return val(t.m_pEntity, ...) end or val	
end

function Smoke()
	local pEntity = ents.Create("env_particlesmokegrenade")
	pEntity.m_flSpawnTime = CurTime()
	pEntity:Spawn()
	
	return setmetatable({m_pEntity = pEntity}, SMOKE)
end
