嗯，，在第50行加上#更新图像
screen.blit(picture,position)试试{:10_245:}

能再问一下嘛在拖延窗口/屏幕大小的时候，在窗口/屏幕重叠图像时，图像的循环颤抖怎么解决呀，哇！！这个bug真的不会解决呀，这个bug时检测两者之间的碰撞，可我知道的碰撞的只有rect和精灵呀，没有surface的{:10_292:}

我一般写游戏都不让用户改大小，就是为了防止这样的问题{:10_250:}，所以俺也没解决掉这个{:10_266:}

看弹幕说可以用 “每次改变都按比例重置乌龟的位置” 不知道行不行，{:10_257:}

这个可以解决鬼畜问题，但俺觉得运用到实际就不是很可行，不可能角色走了一段路用户改一下窗口大小，角色又回到原地吧{:10_254:}

多加了放大和缩小的键，又有新bug了{:10_266:}，在放大图像的时候：图像一边移动一边放大，放大的图像会移出右下，我知道放大的是像素，position还是原来的position，然后我用放大后的尺寸，放在blit的第一个参数里，再赋给opicture，可是为什么有循环颤抖呀（我想法错了嘛{:9_229:}）
