【问题描述】：
我正在尝试检测我的两个精灵何时发生碰撞。我做的第一件事是在我的播放器周围创建一个矩形（称为 player.img），然后在我想要检测的树周围创建另一个矩形（称为 background.treesrect）。我将玩家矩形的坐标设置为等于当玩家通过用户按键移动但玩家矩形不移动时更新的坐标。然后我使用 sprite.colliderect(sprite) 函数来检测它们是否发生碰撞并且它没有检测到。有人可以告诉我为什么我的播放器矩形没有更新以及其他任何可能有问题的地方吗？
编辑我只是通过将绘制矩形的函数而不是玩家类放入游戏循环中来解决碰撞问题，但我遇到了另一个奇怪的问题。由于某种原因，矩形移动得比玩家精灵快，我不知道如何让玩家精灵在背景之上而不显示玩家矩形。
