Set color to the light ?

[wh1sp3r]

I have problem to set a color to my directional light

 

local light = class:GetLight() -- this function returns first direction light handle

light:SetColor( Vec4(1.0/255.0, 0.0/255.0, 0.0/255.0 ,1.0) )

 

 

light handle is OK, because i can rotate light but i can'T set color.

 

thank you

That code sets it to almost black. Is that what you wanted?

[wh1sp3r]

... ok, wrong math, lol

 

but still .. color of light is not changing

 

for example : light:SetColor( Vec4(0, 1, 0 ,1.0) )

for green light and nothing

looks like you are trying to set the color for the light class and not the light model. Need to see your complete code to be able to tell for sure whats going on...

[wh1sp3r]

function class:GetLight()

class = classnametable[ "light_directional" ]

if class~=nil then

for model,object in pairs(class.instances) do

return model

end

end

end

hmmm this seems to work fine for me...

 

require("scripts/class")

local class=CreateClass(...)

function class:GetLight()
class = classnametable[ "light_directional" ]
if class~=nil then
	for model,object in pairs(class.instances) do
		return model
	end
end
end 

function class:CreateObject(model)
local object=self.super:CreateObject(model)

local light=class:GetLight()
light:SetColor(Vec4(0,1,0,1), 1)
end

 

when I place the entity that has this script into the scene it instantly changes the directional light's color...

[wh1sp3r]

yes, me too ... reason ?

 

your code light:SetColor(Vec4(0,1,0,1), 1)

my code light:SetColor(Vec4(0, 1, 0 ,1.0) )

 

what is a second parameter ?

[macklebee]

its the recursive parameter to EntityColor
