問題は

_nextProjectile = [[CCSprite spriteWithFile:@"newarrow.png"]retain]; _nextProjectile.position = ccp(430,190);

init メソッドで __nextProjectile を初期化しているときに ccTouchBegan メソッドが機能しません.. _nextProjectile = [[CCSprite spriteWithFile:@"newarrow.png"]retain]; _nextProjectile.position = ccp(430,190); ccTouch では、Touch が実行されるたびに初期化するようになりました。何か助けて?!!

同じレイヤーのタッチを有効にします。

-(void)onEnter
{
    [super onEnter];

    self.touchEnabled = YES; //In Cocos2d 1.0: self.isTouchEnabled
}



- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *touch = [touches anyObject];
    CGPoint location = [touch locationInView: [touch view]];
    location = [[CCDirector sharedDirector] convertToGL:location];

}
