gamelogic scheduleUpdate

@interface GameplayLayer : CCLayer <GameplayLayerDelegate> { CCSprite *vikingSprite;SneakyJoystick *leftJoystick;SneakyButton *jumpButton;SneakyButton *attackButton;     CCSpriteBatchNode *sceneSpriteBatchNode;}@end

#pragma mark –#pragma mark Update Method-(void) update:(ccTime)deltaTime {CCArray *listOfGameObjects =            [sceneSpriteBatchNode children]; // 1for (GameCharacter *tempChar in listOfGameObjects) { // 2        [tempChar updateStateWithDeltaTime:deltaTime andListOfGameObjects:                     listOfGameObjects]; // 3    }}

需要更新的game object放到一个batchNode中，每帧通过children取出。而不需要持有每个对象。

 Sets up a scheduler call that will f ire the update method in GameplayLayer.m on every frame.
