_ball = [CCSprite spriteWithFile:@"ball.png" rect:CGRectMake(0, 0, 52, 52)];
_ball.position = ccp(300, 300);
[self addChild:_ball];
_ball1 = [CCSprite spriteWithFile:@"ball.png" rect:CGRectMake(0, 0, 52, 52)];
_ball1.position = ccp(300, 300);
[self addChild:_ball1];
if (_ball1.position.x == _ball.position.x && _ball1.position.y == _ball.position.y) {
NSLog(@"Stop");
}
_ball が touch _ball1 の場合、これで何か問題がありますか?
