碰撞检测的边界框重叠并引发问题

在这种情况下我所做的是：

• 正常执行位移（即将角色的运动矢量添加到其位置）
• 检查所有障碍物是否发生碰撞。如果发生碰撞，将角色"传送"到远离障碍物的地方，比如一个像素。继续执行此操作，直到不再发生碰撞

这可能不是运行最快的解决方案，但它可以完成任务。当有许多动态的东西也可能发生碰撞时，效果很好。

经过多次戴头巾和酗酒，我终于想出了一个解决方案。我甚至把它放在一个班级里，这样其他人就可以用它来帮助他们解决类似的问题。

这有点简单：-您使用正在检查的两个碰撞框（矩形）实例化类。-您可以检查以确保它们确实发生了碰撞。-要使用StopOnCollision，您需要输入正在移动的物体的位置（参考的x，y坐标）、要用来改变或阻止其移动的矢量，以及物体移动的速度（每帧像素）

我希望这能像帮助我一样帮助其他人。
