在我的游戏中，你从“神模式”开始，在那里你可以放置物体。然而，当您完成放置物体并进入“运行模式”时，游戏就会实时进行，并且会发生碰撞和其他物理效应。
所以我现在在游戏中的碰撞只能在部分时间内完成。
按空格键时，会在鼠标位置生成'house1'图像，并设置house1的XY坐标，并设置house1InWorld = True（影响碰撞）。
由于house1inWorld属性，在生成house1图像时碰撞生效。因此，如果按r（进入运行模式），则碰撞适用于一个house1实例。但是当你产生2个house1实例（在不同的位置）时，碰撞只适用于最近放置的house1。
我应该如何更改我的代码，以便无论你生成多少个house1，碰撞都会起作用？
答案 0 :(得分：1)
您只存储最后放置的房屋的位置并检查碰撞。
您应该创建一个房屋位置列表，然后循环检查房屋位置以检查是否存在碰撞。 像这样：
houses1XY = []
houses1XY.append(mouse)
#and later
for house1XY in houses1XY:
house1Rect = pygame.Rect(house1XY[0], house1XY[1], 64, 64)
由于您将房屋移至列表，因此您不再需要houseInWorld。您已经在列表中获得了相关信息。您可以检查列表是否为空 - ＆gt;所以通过评估列表已经放置了一所房子。如果它不为空，则返回true。
if houses1XY:
#enable realtime etc.
