Cocos2d iphone 请帮助触摸数组中的特定精灵，它们正在删除代码

我试着用位置来检测特定的精灵，当我使用“if”语句时，构建失败了

这是我的密码

 -(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{

UITouch* myTouch = [touches anyObject];
CGPoint location = [myTouch locationInView: [myTouch view]];
location = [[CCDirector sharedDirector]convertToGL:location];

int numGrades = [grades count]; 
for (int i = 0; i < numGrades; i++) 
{
    // Put each spider at its designated position outside the screen 
    CCSprite* grade = [grades objectAtIndex:i];

int numGrades = [grades count]; 
for (int i = 0; i < numGrades; i++) 
{
    CCSprite* grade = [grades objectAtIndex:i];

请更正“如果”语句

看来您只是想检测到精灵的触碰。您当前的交叉点测试要求您的触摸坐标与精灵的中心点完全匹配，这实际上是不可能的

相反，您应该尝试根据精灵的边界框测试触摸坐标

if (CGRectContainsPoint(grade.boundingBox, location))     
{
    [grade stopAllActions];     
} 

也请注意，它是带“s”的stopAllActions

希望这对您有所帮助。

可能的副本

if (CGRectContainsPoint(grade.boundingBox, location))     
{
    [grade stopAllActions];     
}
