我已经实现了对精灵对象的拖动,如下所示。
-(BOOL)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch * touch = [touches anyObject];
CGPoint location = [[Director sharedDirector] convertCoordinate: [touch locationInView:touch.view]];
[diskSprite setPosition:ccp(location.x , location.y )];
return kEventHandled;
}
但这个拖拽并不顺利......
当我用拇指快速拖动时,对象从路径中离开。
Thanks
可能有点晚了,但我正在寻找类似的东西。
我发现这个很棒的教程解释了一切:http://www.raywenderlich.com/2343/how-to-drag-and-drop-sprites-with-cocos2d http://www.raywenderlich.com/2343/how-to-drag-and-drop-sprites-with-cocos2d
- (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);
CGPoint newPos = ccpAdd(mySpriteToMove.position, translation);
mySpriteToMove.position = newPos;
}
