结点添加、删除、获取
1.结点：CCNode * childNode = [CCNode node];
2.加入结点
[myNode addChild:childNode z:0 tag:123];//z决定绘制的顺序
3.获取结点
CCNode * retrieveNoded = [myNode getChildeByTag:123];
4.删除 cleanup:YES正在运行的动作停止
[myNode removeChildByTag:123 cleanup:YES];
[myNode removeChild:retrievedNode];
[myNode removeAllChildrenWithCleanup:YES];
[myNode removeFromParentAndCleanup:YES];
动作处理
CCAction * action = [CCBlink actionWithDuration:10 blinks:20];
action.tag = 234;
1.运行
[myNode runAction:action];
2.获得
getActionByTag
3.停止
stopActionByTag:
stopAction:
[myNode stopAllActions]
消息调度
[self scheduleUpdate];
-(void) update:(ccTime)delta
{}
[self schedule:@selector(xxx:) interval:0.1f];
[self scheculeOnce:@selector(xxx:) delay:600];
//取消计时
[self unscheduleAllSelectors];
[self unscheduleUpdate];
[self unschedule:@selector(xxx:)];
[self unschedule:_cmd];//_cmd相当于@selector(本身)
float nextUpdate = CCRANDOM_0_1()*10;
//附加，了解即可
[self scheduleUpdateWithPriority:1];//-1,越小优先调用
Director类（类似ScreenMgr类）
1.获取
[Director sharedDirector];
2.场景运行
runWithScene、replaceScene、pushScene
3.场景添加进CCTransitionScene;
