Andengine Collisions - 检测碰撞和删除物体时的例外情况

Question

我正在开发一款动力驱动的box2d游戏。当我尝试从场景中删除碰撞的物体时，有时会发生错误。好像这是一个随机错误。

Uncaught handler: thread GLThread exiting due to uncaught exception

请帮忙。

您正在删除UI线程上的正文。这意味着当绘制场景时，它正在尝试绘制一些未附加到场景的东西，并且您得到了ArrayIndexOutOfBoundsException。如果使用runOnUpdateThread而不是runOnUiThread，则不应该出现问题。
