Wired Movies and Sprites

Hit Testing Flags

The following hit testing flags are included in QuickTime 3. These flags are used with both the sprite toolbox and the movie sprite track hit testing routines:

spriteHitTestInvisibleSprites , which you set if you want invisible sprites to be hit tested along with visible ones.
spriteHitTestLocInDisplayCoordinates , which you set if the hit testing point is in display coordinates instead of local sprite track coordinates.
spriteHitTestIsClick , which you set if you want the hit testing operation to pass a click on to the codec currently rendering the sprites image. For example, this can be used to make the Ripple Codec ripple.
