iphone - 多点触控在 cocos2d 中不起作用

Question

这是我的 ccTouchesMoved 方法。怎么了？我使用cocos2d框架。

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

CCNode *sprite = [self getChildByTag:kTagPlayer];
CCNode *sprite2 = [self getChildByTag:kTagEnemy];

CGPoint point;

//Собрать все касания.
NSSet *allTouches = [event allTouches];

for (UITouch *touch in allTouches)
{
    point = [touch locationInView:[touch view]];
    point = [[CCDirector sharedDirector] convertToGL:point];

    if (point.y > 384)
    {
        if (point.x > 992)
            sprite2.position = ccp(992, size.height - 100);
        else if (point.x < 32)
            sprite2.position = ccp(32, size.height - 100);
        else
            sprite2.position = ccp(point.x, size.height - 100);
    }
    else
    {
        if (point.x > 992)
            sprite.position = ccp(992, 100);
        else if (point.x < 32)
            sprite.position = ccp(32, 100);
        else
            sprite.position = ccp(point.x, 100);
    }
} 

}

您是否在 glView 中启用了多次触摸？默认情况下，glView 在应用程序委托(delegate)中实例化。代码如下。

[glView setMultipleTouchEnabled:YES];
