public int createAnimatedTile(int staticTileIdx)

throws

IndexOutOfBoundsException

– Creates a new animated tile and

initializes it with a static tile index. Returns the index to use when referring to this

animated tile. The indices for animated tiles will be negative (<0) and the indices for
the static tile set will be positive (>=0). The index sets do not overlap and therefore
indices for static and animated tiles can be used interchangeably in the methods that

set or move the contents of the PlayField cells. The first animated tile shall have the
index -1, the second, -2, etc.

•

public void setAnimatedTileImage(int animTileIdx,

int staticTileIdx)

throws

IndexOutOfBoundsException

The method parameters are

animTileIdx

public int getAnimatedTileImage(int animTileIdx)

throws

cell. The tile can be either a static or an animated tile. The method parameters are

celCol

- column of cell to set,
