我需要随机重复我的障碍。现在我只有2个障碍，但会加上。我想保持对象取向。每当我尝试这样做时，它会调用随机变量变量，它会多次调用我的障碍物，或者它会调用一个障碍物然后不再重复另一个障碍物。
答案 0 :(得分：0)
如果你想让你的同一个障碍随机重复，最简单的方法就是在你的游戏循环中添加一个子句来检查对象是否在屏幕外，如下：
import pygame

screen_width = 500
screen_height = 500

otherLeft = obstacleX
otherTop = obstacleY
otherBottom = obstacleY + obstacleHeight
#now the collision code

if ((myRight < otherLeft) or (myLeft > otherRight) or (myBottom < otherTop) or (myTop > otherBottom)):

return collision

这使得块在到达底部时会到达屏幕顶部，但有时它不会等待一段距离，从而改变循环的频率。它还会随机改变障碍物的方向
