在cocos2d遊戲開發中,CGRectContainsPoint方法經常用來檢測是否觸碰到CCSprite。如何以方便的方式獲取精靈矩形?
我用代碼fllow得到一個精靈的(這在CCNode)rect屬性
- (void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event { CCLOG(@"ccTouchEnded"); CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; CCLOG(@"location.x:%f, y:%f", location.x, location.y); CGRect rect; rect = CGRectMake(self.firstCard.face.position.x-(self.firstCard.face.contentSize.width/2), self.firstCard.face.position.y-(self.firstCard.face.contentSize.height/2), self.firstCard.face.contentSize.width, self.firstCard.face.contentSize.height); if (CGRectContainsPoint(rect, location)) { CCLOG(@"first card touched"); [firstCard open]; } rect = CGRectMake(self.secondCard.face.position.x-(self.secondCard.face.contentSize.width/2), self.secondCard.face.position.y-(self.secondCard.face.contentSize.height/2), self.secondCard.face.contentSize.width, self.secondCard.face.contentSize.height); if (CGRectContainsPoint(rect, location)) { CCLOG(@"second card touched"); [secondCard open]; } }
我想知道如果有一種方便的方式獲得CCSprite的矩形簡單?
你可以通過精靈值爲[sprite_nm boundingBox的]。方法。我認爲它會對你有用。它返回整個Rect。 – Marine 2012-01-11 05:51:42
