Game Cutter Guidelines

The cutter, or mask, operation in Harmony is used for cutting off drawings with custom shapes. The game engine SDK implements both cutters and inverted cutters with the following limitations:

  • For a sprite, only a single cutter drawing can be applied when it is rendered. This also applies to a composite of multiple matte drawings. The game engine SDK will only use the first matte drawing during rendering and discard the others.
  • A deformed drawing cannot be cut, but a cut drawing can be deformed.
NOTE: * Not currently available in the Cocos2d-x implementation of the game engine SDK.
