how can i use callback function?

[hyein6790]

i hope to make a function for creating models simply

function TestModel(pos,model,callback)
local ent = ents.CreateClientProp()
ent:SetPos(pos)
ent:SetAngles(Angle(0,0,0))
ent:SetModel(model)
ent.RenderOverride() = function()
---------- i hope to adding callback in this line --------
callback(ent)

end

usage

TestModel(self:GetPos(), "models/hunter/plates/plate1x1.mdl", function(ent)
ent:DrawModel()
print("ent test!")
end)

i already asked about this question but answers did not help.

I already told you what to do in your last thread: you just set ent.RenderOverride to callback, you don't wrap it in another function. I also don't get why you're adding parentheses next to RenderOverride.

You got pretty accurate answers in the previous thread.
If you want ent.RenderOverride to do something, simply add the code inside of the function, it's pretty simple.

then i can't never ever adding callback into ent.RenderOverride?

you mean
ent.RenderOverride() = callback
but my hope is
ent.RenderOverride() = function()
callback()
with E.T.C
end
so i hope to add some code inside of ent.RenderOverride() with callback()

So how about you put the rest of the code into callback? :/

the reason why i want to do this is because it's more simple..

[lua]function ent:RenderOverride()
self:DrawModel() -- default behavior
-- any code you want
end[/lua]

or, if you want to use the same function for many different entities:
[lua]local function YourRenderFunction(self)
self:DrawModel() -- default behavior
-- any code you want
end

-- ... later, probably in some hook where you have an ent
ent.RenderOverride = YourRenderFunction -- notice, no parentheses in this line![/lua]
