【问题描述】:
我有一个精灵,我想用手指在屏幕上移动~拖动来移动它。 我希望我的精灵以速度移动,这意味着不要像我的手指移动那么快。
好像是这个视频:http://www.youtube.com/watch?v=Vair3CIxZEw(从 0:12 到 0:53)
这是我的 ccTouch 代码。我该如何解决以使其移动看起来更流畅?
谢谢!!! :)
直接返回 TRUE
-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {
return TRUE;
}
和
-(void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event {
CGPoint touchLocation = [self convertTouchToNodeSpace:touch];
CGPoint oldTouchLocation = [touch previousLocationInView:touch.view];
oldTouchLocation = [[CCDirector sharedDirector] convertToGL:oldTouchLocation];
oldTouchLocation = [self convertToNodeSpace:oldTouchLocation];
CGPoint translation = ccpSub(touchLocation, oldTouchLocation);
if (CGRectContainsPoint(_car.boundingBox, touchLocation)) {
CGPoint newPos = ccpAdd(_car.position, translation);
_car.position = newPos;
}
}
