Pygame：只有一部分圈子在吃东西

Question

我试图让一个圆圈在接触某物时摧毁它。然后它会长一点。最终在一定尺寸时，我可以注意到只有圆圈内的正方形区域实际上在吃它。

怎样才能让整个圆圈都能吃到周围的东西？

Answer 1

你在开始时将 player 设置为初始大小的圆圈，然后你就再也没有更新过它。当您重新绘制播放器时，您只是在绘制一个具有新尺寸的新圆圈。您需要将新绘制的圆重新分配给 player 变量。您可能还需要将一些数据从旧的 player 复制到新播放器，但我对 pygame 不是很在行，所以我不确定各种属性中的哪一个（如果有的话） player（如 center 和 left）由 pygame 处理，您正在自己创建。
