你如何完全使用CCSequence內緩存？

Answer 1

這裏就是一個例子。這將我的mapNode帶回到左邊界，例如當LHS菜單彈出時。移動持續時間和加速度計算爲期望位移的函數：

- (void)setLeftClamp:(float)leftClamp { 

    _leftClamp = leftClamp; 

    CGPoint currentPosition = self.mapNode.position; 
    if (currentPosition.x > self.maxX) { 
     // ease right back in position 
     CGPoint delta   = ccp (self.maxX - currentPosition.x, 0); 
     id  move   = [CCMoveBy actionWithDuration:[self moveDuration:delta] position:delta]; 
     id  ease   = [CCEaseIn actionWithAction:move rate:[self moveAcceleration:delta]]; 
     id  delay   = [CCDelayTime actionWithDuration:.1f]; 
     id  easeAndCenter = [CCSequence actions:ease, delay, [CCCallFunc actionWithTarget:self selector:@selector(onMoveComplete)], nil]; 
     [self.mapNode runAction:easeAndCenter]; 

     targetMapLocation_ = ccpAdd(self.mapNode.position, delta); 
     mapDisplacement_ = delta; 
     isMapMoving_  = YES; 

    }
