Objective c cocos2d中的屏幕撕裂

objective-c cocos2d-iphone

Objective c cocos2d中的屏幕撕裂,objective-c,cocos2d-iphone,Objective C,Cocos2d Iphone,我培养了无止境的跑步者。我使用“更新”移动对象 -(void) update:(CCTime)delta{ ast.position = ccpAdd(ast.position, ccpMult(ccp(-200,0), delta)); if(ast.position.x<-100) [ast setPosition:ccp(_winSize.width+100,ast.position.y)]; } -（无效）更新：（CCTime）增量{ ast.position=ccpAdd

我培养了无止境的跑步者。我使用“更新”移动对象

-(void) update:(CCTime)delta{
ast.position = ccpAdd(ast.position, ccpMult(ccp(-200,0), delta));
if(ast.position.x<-100)
   [ast setPosition:ccp(_winSize.width+100,ast.position.y)];
}

-（无效）更新：（CCTime）增量{
ast.position=ccpAdd（ast.position，ccpMult（ccp（-200,0），增量））；

如果（ast.position.x这不是屏幕撕裂，这是与增量时间相乘的副作用。简短回答：不要与增量时间相乘：
