2つのスプライトを次のように検出しようとしています...しかし、ゲームを実行しようとすると、衝突は起こりません。Cocos2dゲームでの衝突検出？
- (void)update:(ccTime)dt {
CGRect projectileRect = CGRectMake(projectile.position.x - (projectile.contentSize.width/2),
projectile.position.y - (projectile.contentSize.height/2),
projectile.contentSize.width,
projectile.contentSize.height);
//CGRectMake(0,220,320,50);
CGRect targetRects = CGRectMake(_monkey.position.x - (_monkey.contentSize.width/2),
_monkey.position.y - (_monkey.contentSize.height/2),
_monkey.contentSize.width,
_monkey.contentSize.height);
if (CGRectIntersectsRect(projectileRect, targetRects)) {
NSLog(@"ha ha Collision detected");
}
}スプライトが下に、画面の上部とスプライトが一番下に左から右にアニメーション化されたサルからアニメーション化され
発射体が発射は猿を通過するが、ログにはありません呼び出される???
