How would I attach a light to a model?

[L B]

I think the title is self-descriptive. What's the simplest script to attach a point light to my model? Thanks.

One way to do that is to use

 

light:SetParent(model)

 

light = your light entity and model = your model

How would I access these objects? I just want to place my streetlamp entity and it already has the light on it. I copied the code from the point light script into the streetlamp script, and it works fine. I have a point light, but at the origin of the model, which is way too low.

 

How would I go making "entity.light" move up?

I tried "entity.light:Move(0, -2, 0)" but this doesn't work.

group:AddProperty("multoffset",PROPERTY_FLOAT,"0,1,2","Multiplicative offset")
group:AddProperty("Range",PROPERTY_FLOAT,"1,100,0")
group:Expand(1)
end

function Spawn(model)
local entity=base_Spawn(model)
entity.model=model
entity.light=CreatePointLight(10,model)
return entity
end

function GetKey( model, key, value )
local entity=entitytable[model]
if entity==nil then return value end
if entity.model==nil then return end
if entity.light==nil then
	return base_GetKey(model,key,value)

Either:

light:Move(Vec3(1,2,3))

light:Movef(1,2,3)

 

I will try to add the "f" version for every command.

What does the "F" do?

What does the "F" do?

Most likely "Fast".
