Android 物理体通过每个

我正在和Andengine+Box2D一起做一个小项目。我有一个玩家角色和一个地面。地面是一个静态物体，而plyaer是动态物体。我想要一个人在地上行走的效果

问题是，当我移动播放器时，它正在下沉。我如何修复它？我必须用图片解释它

这是我的密码：

很可能这是因为你的物理身体的大小或形状与你的精灵不同。 我不知道任何简单的方法来修改它。可能是你必须为精灵创建自己的形状。 但是这里有一个很好的工具箱2D debug renderer供您使用，您可以使用它来获得物理体的轮廓。

使用起来非常简单，只需将项目作为库包含，然后添加一行代码即可

mScene.attachChild(new Box2dDebugRenderer(mPhysicsWorld));

现在你所有的物理身体都会显示一个轮廓，

请记住，此问题将减少FPS，但对调试非常有帮助。

您需要在问题中包含更多信息，以避免问题被关闭。包括一个外部网站的链接也不能代替发布一个完整的问题。所以，没有人知道或者我不能很好地解释我的问题？谢谢你的回答，但我找不到下载链接。顺便说一下，它说Box2DebugRenderer已过时。是否有更新的版本？很抱歉，错误的链接编辑了文章，并将新链接添加到pastebin copy并使用它：）
