Shader: setNumberOfPasses

setNumberOfPasses(num)
  • Sets the number of times the shader is applied to the material.

num:

  • number of passes
     
  • Type: integer
Note:
  • Shaders work with Viewport Shading GLSL and Viewport Shading Multitexture.
     
  • Shaders don't work with Viewport Shading Singletexture.
Sample Code

############################# set the number of passes


############## main program

def main():

# import bge
import bge

# get the current controller
cont = bge.logic.getCurrentController()

# get object that owns this controller
obj = cont.owner
 
# Get a list of the mesh
meshList = obj.meshes

# Get the first mesh on the object
mesh = meshList[0]
 
# only one material on mesh
mat = mesh.materials[0]

# Using Blender GLSL Materials or Blender Multitexture Materials?
if hasattr( mat, 'getMaterialIndex') == True:
 
# get shader envelope
shader = mat.getShader()

# did it get the shader envelope?
if shader != None:
 
# set the source and use it
shader.setSource(VertexProgram,FragmentProgram, True)

# set number of passes to 3
shader.setNumberOfPasses(3)
