Background Cocos 2d背景地图手势

Cocos2d对我来说是全新的，所以我不知道该怎么处理这种情况：

我想做一个类似冒险的游戏。现在我制作了一个背景图像，就像一张世界地图（只是为了测试）。在这张地图上，我需要一个滑动手势，这样我就可以在我的ipad上移动地图了（地图很大，所以我想在周围滑动）

我的问题是我不知道我应该使用什么对象。以及如何以最佳方式实现手势（我是否需要自己计算动作？）

谢谢！

我想您正在寻找这个来添加一个对象：

CCSprite *objectName = [CCSprite spriteWithFile:@"fileName.png"];
    [self addChild:objectName];

默认情况下，我相信对象将位于左下角

您可以将UIKit的平移手势识别器连接到CCDirector的视图，并在CCLayer类中处理平移手势。这样，您就可以使用handle方法，该方法可以随着每次平移移动背景。（COCOS2D1.0.1的代码，2.0版本也可以这样做）

处理程序方法如下所示：

- (void)handlePanGesture:(UIGestureRecognizer*)gestureRecognizer {
 // If there is more than one pan gesture recognizer connected with this method, you should remember pan and check if gestureRecognizer is equal to pan 

 switch (gestureRecognizer.state) {
    case UIGestureRecognizerStateBegan: {

        // Do something that needs to be done when pan gesture started

        break;
    }
    case UIGestureRecognizerStateChanged: {

        // Get pan gesture recognizer translation
        CGPoint translation = [(UIPanGestureRecognizer*)gestureRecognizer translationInView:gestureRecognizer.view];

        // Invert Y since position and offset are calculated in gl coordinates
        translation = ccp(translation.x, -translation.y);

        // Here you should move your background, probably in oposite direction of translation vector, something like
        background.position = ccp(background.position.x - translation.x, background.position.y - translation.y);

        // Refresh pan gesture recognizer
        [(UIPanGestureRecognizer*)gestureRecognizer setTranslation:CGPointZero inView:gestureRecognizer.view];

        break;
    }
    case UIGestureRecognizerStateEnded: {

        // Do some work that should be done after panning is finished

        break;
    }
    default:
        break;
    }
}

- (void)handlePanGesture:(UIGestureRecognizer*)gestureRecognizer {
 // If there is more than one pan gesture recognizer connected with this method, you should remember pan and check if gestureRecognizer is equal to pan 

 switch (gestureRecognizer.state) {
    case UIGestureRecognizerStateBegan: {

        // Do something that needs to be done when pan gesture started

        break;
    }
    case UIGestureRecognizerStateChanged: {

        // Get pan gesture recognizer translation
        CGPoint translation = [(UIPanGestureRecognizer*)gestureRecognizer translationInView:gestureRecognizer.view];

        // Invert Y since position and offset are calculated in gl coordinates
        translation = ccp(translation.x, -translation.y);

        // Here you should move your background, probably in oposite direction of translation vector, something like
        background.position = ccp(background.position.x - translation.x, background.position.y - translation.y);

        // Refresh pan gesture recognizer
        [(UIPanGestureRecognizer*)gestureRecognizer setTranslation:CGPointZero inView:gestureRecognizer.view];

        break;
    }
    case UIGestureRecognizerStateEnded: {

        // Do some work that should be done after panning is finished

        break;
    }
    default:
        break;
    }
}
