how can i use callback function?

[hyein6790]

function TestModel(pos,callback,model)
local ent = ents.CreateClientProp()
ent.RenderOverride = function()
callback(ent)
end
ent:SetPos(pos)
ent:SetModel(model)
ent:SetAngles(Angle(0,0,0))
end

TestModel(self:GetPos(),function(ent)
print("test !!")
ent:DrawModel()
end,"models/hunter/tubes/tube4x4x1to2x2.mdl")

how can i use callback? this code not working X(
someone help me for using callback :)

RenderOverride only works for Lua entities -- clientside props are engine ents.

then why this code works fine?

			local rocks = {
				"models/props_wasteland/rockcliff01b.mdl",
				"models/props_wasteland/rockcliff01c.mdl",
				"models/props_wasteland/rockcliff01e.mdl",
				"models/props_wasteland/rockcliff01f.mdl",
				"models/props_wasteland/rockcliff01g.mdl",
				"models/props_wasteland/rockcliff01j.mdl",
				"models/props_wasteland/rockcliff01k.mdl",
			}
				for i = 1, 2 do
					local offset = VectorRand() * scale * 50
					local trace = util.TraceLine({start = self:GetPos() + offset * scale, endpos = (self:GetPos() + offset) + normal * -100, mask =  MASK_SOLID_BRUSHONLY })
					if trace.Hit then

						local life_time = 0.6

						local ent = ents.CreateClientProp()
						SafeRemoveEntityDelayed(ent, life_time)

						local time = RealTime()
						local s
						local rand = math.random() * 500
						ent.RenderOverride = function()
							s = s or ent:GetModelScale()
							local fade = RealTime() - time
							fade = math.Clamp((-fade + life_time) / life_time, 0, 1)

							local scale = (math.min((fade ^ 0.5) + 0.5, 1) - 0.5)

							ent:SetModelScale(scale * s)
							ent:DrawModel()
						end

						ent:SetModel(table.Random(rocks))

						ent:SetPos(trace.HitPos)
						ent:SetAngles(trace.HitNormal:Angle() )

						ent:SetModelScale(scale * math.Rand(0.3, 0.5)/2)
						ent:SetCollisionGroup(COLLISION_GROUP_PROJECTILE)
						ent:PhysicsInitBox(Vector(1,1,1) * -5*scale, Vector(1,1,1) * 5*scale)

						local phys = ent:GetPhysicsObject()
						phys:Wake()
						phys:AddVelocity((normal*2 + VectorRand()) * 100 * scale)
						phys:AddAngleVelocity(VectorRand()*200)
						phys:SetMaterial("default_silent")

						local trace_check = trace.Hit and trace.HitTexture ~= "**empty**" -- Check if we're actually hitting a texture that exists.
						local color = Vector(0,0,0)

						if trace_check then 
							color = render.GetSurfaceColor(trace.HitPos + normal, trace.HitPos + (normal * -100))
						end
						
						ent:SetColor(Color(color.x*255, color.y*255, color.z*255))
					end

This hook works on any entity (scripted or not) it is applied on.

thanks, can you help me for adding callback into renderoverride()?

Ah, didn't see that note.

Do ent.RenderOverride = callback instead. No need to wrap the function.

thanks , but i can't call it inside of renderoverride?

It will be called automatically by the callback.

no, i mean this case how to get ent parameter?

TestModel(self:GetPos(),function(ent)
print("test !!")
ent:DrawModel()
end,"models/hunter/tubes/tube4x4x1to2x2.mdl")

[c👌de_g🎷]

It will provide the ent parameter automatically if you do what I said above.
