Coding the object cleanup functions
The
object cleanup functions
are
dispose
and
disposeAll
.
The
dispose
function takes in a single
BlitSprite
(or its child,
TileByTileBlitSprite
) and
removes it from the screen and readies it for garbage collection. It calls the internal
dispose
function of the
BlitSprite
class and removes the object from the display list.
The
disposeAll
function calls
dispose
on all of the objects in the game. It is called at the end of
each level and at the end of the game.
private function dispose(object:BlitSprite):void {
object.dispose();
removeChild(object);
}
private function disposeAll():void {
dispose(player);
for each(tempEnemy in enemyList) {
dispose(tempEnemy)
}
enemyList = null;
for each(tempMissile in playerMissileList) {
dispose(tempMissile)
}
playerMissileList = null;
for each(tempMissile in enemyMissileList) {
dispose(tempMissile)
}
enemyMissileList = null;
for each(tempExplode in explosionList) {
dispose(tempExplode)
}
explosionList = null;
