我是Android 游戏开发的新手，我正在使用AndEngine GLES 2 Java。在这个编码中，我创建了 2 个精灵，分别是small_box和big_box 。当我将small_box拖到big_box或相反时，它会相互排斥。这很好用，但我的问题是第一个small_box和第一个big_box相互排斥，但是第二个small_box和big_box不排斥。如何解决？我想要所有big_box的所有small_box排斥，当我将small_box拖到另一个small_box 时它应该重叠，甚至在big_box到另一个big_box也......请任何人都可以通过修改此代码或使用示例来帮助这个......
