Pygame 按键应该只调用一次函数
Pygame keypress should call function just once
嗨，标题说的基本上都是...
再描述一下：
它是一个 2D 随机瓦片地图，你可以在上面移动玩家，他可以开采煤炭。
问题是，如果他站在煤上并按 space 不止一次，那么煤就会被多次添加到他的库存中，那就是 problem.He 可以开采更多的煤，甚至没有更多.
我搜索了 google 但我唯一发现的是我必须使用标志，一些布尔值......但是如何？
我知道代码写的很脏，很丑等等...可以优化...

你的代码有很多问题，但让我们专注于你的问题：
aba=playerRect.collidelist(coalRect_list)
aba 现在包含 coalRect_list 中与 playerRect 或 -1.
冲突的第一个 Rect 的索引
if aba!=1:
if sSpace==True:
minedCoal.append(aba)
mapO.mineCoalAt(aba)
else:
pass
我猜你想在这里检查 aba != -1，因为 -1 表示没有发生碰撞：
if aba != -1 and sSpace:
...
现在怎么办取决于你，但我想你想从地图上移除煤炭，所以你可以简单地从 coalRect_list
中移除 Rect
if aba != -1 and sSpace:
minedCoal.append(aba)
mapO.mineCoalAt(aba)
del coalRect_list[aba]
因为你只用coalRect_list检查煤炭是否可以开采，这应该足够了。
