我如何更快地移动恐龙游戏中的障碍物
how do i move obstacles faster for dino game
我正在尽最大努力制作恐龙游戏复制品，但我一直坚持提高障碍物到达角色的速度。 5 的速度似乎是一个神奇的数字，但当我将其更改为 6 时，岩石没有被检测到，最终也不会产生下一块岩石。
我不知道为什么。
没有错误，除了当岩石没有生成并且我得到一个超出范围的索引时：
Traceback (most recent call last):
File "C:\Users\austi\OneDrive\Desktop\scroller game\main.py", line 109, in <module>
main()

if game.collide():

olh = self.obstacles[0].hitBox[0]

我怀疑问题出在 main.py
游戏 class 的生成函数中
几天来我一直在努力解决这个问题，但我仍然无法解决我的问题。
问题是条件
if obstacle.pos.x + obstacle.w == WIDTH/2 + self.spawnGap:
# [...]
只有当障碍物恰好在某个位置时，这种情况才会True。如果速度发生变化，障碍物并没有准确命中位置。
在小范围而不是位置上进行测试。例如：
right = obstacle.pos.x + obstacle.w
target = WIDTH/2 + self.spawnGap
if traget <= right < traget + speed:
# [...]
