| #define CC_BLEND_DST GL_ONE_MINUS_SRC_ALPHA |
default gl blend dst function. Compatible with premultiplied alpha images.
Definition at line 100 of file ccMacros.h.
| #define CC_BLEND_SRC GL_ONE |
default gl blend src function. Compatible with premultiplied alpha images.
Definition at line 95 of file ccMacros.h.
| #define CC_DEGREES_TO_RADIANS | ( | __ANGLE__ | ) | ((__ANGLE__) * 0.01745329252f) |
converts degrees to radians
Definition at line 85 of file ccMacros.h.
| #define CC_DIRECTOR_END | ( | ) |
do { \ CCDirector *__director = [CCDirector sharedDirector]; \ EAGLView *__view = [__director openGLView]; \ [__view removeFromSuperview]; \ [__director end]; \ } while(0)
Stops and removes the director from memory. Removes the EAGLView from its parent

| #define CC_DIRECTOR_INIT | ( | ) |
do { \ window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; \ if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] ) \ [CCDirector setDirectorType:kCCDirectorTypeNSTimer]; \ CCDirector *__director = [CCDirector sharedDirector]; \ [__director setDeviceOrientation:kCCDeviceOrientationPortrait]; \ [__director setDisplayFPS:NO]; \ [__director setAnimationInterval:1.0/60]; \ EAGLView *__glView = [EAGLView viewWithFrame:[window bounds] \ pixelFormat:kEAGLColorFormatRGB565 \ depthFormat:0 /* GL_DEPTH_COMPONENT24_OES */ \ preserveBackbuffer:NO]; \ [__director setOpenGLView:__glView]; \ [window addSubview:__glView]; \ [window makeKeyAndVisible]; \ } while(0)
IMPORTANT: If you want to use another type of render buffer (eg: RGBA8) or if you want to use a 16-bit or 24-bit depth buffer, you should NOT use this macro. Instead, you should create the EAGLView manually.
