Shaders

[.:HyPeX:.]

Hey guys I've done so far an implementantion of the UV_Scripted shader from the wiki on a map with an image, but, i want to know if it is possible to make it for ALL the objects under that category (billboard) to have that effect. Else i could just add various object under the line of creating...

Eg:

  
-- Create object with model 4729 (billboard) 
createObject ( 4729, 1850, -4370, 10, 0, 0, 22 ) 
createObject ( 4729, 1850, -4380, 10, 0, 0, 22 ) 
createObject ( 4729, 1850, -4390, 10, 0, 0, 22 )

Well, you can just replace the texture, since specifing a element is optional.

Yes, but i'm not sure how to do it with the DxDraw the UV scripted shader has.

Post your shader script ( not the .FX file, the lua file )

Bump, any idea?

Make the object before engineApplyShaderToWorldTexture

objectShader = createObject

engineApplyShaderToWorldTexture ( myShader, "bobo_2",objectShader )

Thanks!
