Getting sun position

[Gandi]

How can i get the direction of the first directional light in the editor??

[Canardia]

PointEntity(pivot,sun);
TVec3 direction=EntityRotation(pivot);

[Gandi]

the problem is, how do i get the sun in the editor??

[Canardia]

I use GetFirstEntityByKey("name","sun"); after I have set the name of the directional light to "sun". This is a function in gamelib, which you can copy into your own library, or use gamelib as it is.

another question...

how can i pass a Vec3 to my shader from lua?

SetShaderVec3 doesn't work, but SetShaderFloat does.. that's a bit strange..

Why don't you pass 3 floats and make the shader create a Vec3 from it?

GLSL:

 

gl_LightSource[0].position

 

lightDirection = normalize(vec3(gl_LightSource[0].position));

 

Honestly never tried it with LE but I wouldn't see why it wouldn't work.
