这是我最近的帖子的扩展。现在我知道onTimer和Thread，开始一个新帖子。
我在主要部分中使用了while循环。替换为onTimer（）和Thread。但结果相同，无法同时移动两个对象。下面列出的代码：任何建议都表示赞赏......这是我第一次使用Python的图形。
使用onTimer的import turtle

答案 0 :(得分：0)
你犯了与原始代码相同的错误，你在那里使动作成为原子 - 你不能阻止你实现跳转的所有while。你需要将跳转分解为不连续的步骤。这是我基于ontimer()的解决方案：

player.showturtle()
player.speed('fastest')

s.setposition(-50, -60)

s2.showturtle()
s3 = s1.clone()
s3.setx(s2.xcor() + 20)
s3.showturtle()

我在使用它的同时还重写了其他东西，折腾了30％的代码。当玩家碰到或从窗户底部掉下来时，你还需要添加关于停止跳跃计时器的内容。
