setBlending
setBlending( source, destination)
Textures are drawn by blending
the incoming (source) RGBA color values with the RGBA color values
already in the frame buffer (destination)
source:
GameLogic.BL_ZERO
GameLogic.BL_ONE
GameLogic.BL_SRC_COLOR
GameLogic.BL_ONE_MINUS_SRC_COLOR
GameLogic.BL_DST_COLOR
GameLogic.BL_ONE_MINUS_DST_COLOR
GameLogic.BL_SRC_ALPHA
GameLogic.BL_ONE_MINUS_SRC_ALPHA
GameLogic.BL_DST_ALPHA,
GameLogic.BL_ONE_MINUS_DST_ALPHA
GameLogic.BL_SRC_ALPHA_SATURATE
destination:
GameLogic.BL_ZERO
GameLogic.BL_ONE
GameLogic.BL_SRC_COLOR
GameLogic.BL_ONE_MINUS_SRC_COLOR
GameLogic.BL_DST_COLOR
GameLogic.BL_ONE_MINUS_DST_COLOR
GameLogic.BL_SRC_ALPHA
GameLogic.BL_ONE_MINUS_SRC_ALPHA
GameLogic.BL_DST_ALPHA,
GameLogic.BL_ONE_MINUS_DST_ALPHA
GameLogic.BL_SRC_ALPHA_SATURATE
Note:
The code below uses a texture's alpha
channel. The Alpha button on the Texture Face tab doesn't
have to be enabled.
Sample
Code
# get the currrent controller
controller = GameLogic.getCurrentController()
# get object that owns this controller
obj = controller.owner
# There's only one mesh
mesh = obj.meshes[0]
# And only one material
mat = mesh.materials[0]
# Using Blender GLSL Materials or Blender Multitexture
Materials?
if hasattr(mat, "getMaterialIndex") == True:
# set blending of pixels to use texture's alpha channel
mat.setBlending(GameLogic.BL_SRC_ALPHA ,
GameLogic.BL_ONE_MINUS_SRC_ALPHA
)

Game developers
can use the game engine to create casual video games,
first and third person shooters, role playing games, racing simulations
and more. The game engine can be used to make both 2D games and 3D
games. Beginning game developers will only need basic knowledge
of
game design and programming to create rich and complex game models with
photo realistic textures to add detail to the graphics of the video
game. Today's games need more than good looking low polygon game
models. Use normal maps and photo realistic textures to create
high
quality game models.
