Pygame.spritecollide（）即使没有接触，也可以检测精灵之间的碰撞

Question

我没有在互联网上找到任何与此类似的问题。我希望pygame能够检测到玩家何时与另一个精灵（例如胸部或其中一个怪物）碰撞，但是它正在检测玩家即使在他们没有触摸的情况下也在与它们碰撞，也请注意，这并不是100％的时间，它们只是在某些区域发生碰撞。

我的目标是使游戏能够检测到玩家何时碰到怪物，然后移除玩家的一把剑并杀死怪物，或者如果玩家没有剑则玩家死亡。还希望在触摸玩家时胸部只能向inventory[]添加一把剑和钥匙，但是只能一次。我可以使用它，但是当您靠近胸部时，它会打开胸部，而您触摸时却会打开，就像怪物一样。

这里是the folder with all the images I am using。

这是我的代码：

Answer 1

稍微玩了一会儿（双关！）：您没有设置胸部的精灵宽度和高度，因此它保持图像的大小– 99x99像素。对collide的调用有效，但它会检查更大的整个图像。

如果将其显式设置为32x32，则collide将开始按预期工作：

    self.rect = self.image.get_rect()
    self.rect.x = x  # 425
    self.rect.y = y  # 327
    self.rect.topleft = self.rect.x, self.rect.y
    print (self.rect.width,self.rect.height)
    self.rect.width = 32
    self.rect.height = 32

-这里的print表示其大小仍为99x99，即图像本身的大小。 （我没有测试，但是您的播放器精灵可能会遇到相同的问题，因为您以相同的方式构造它。）

要使其在您附近时打开，请将其rect.x，rect.y，rect.width和rect.height更改为更大的矩形。

  

还希望胸部在触摸播放器时向清单[]添加一把剑和一把钥匙，但只能一次。

嗯，您必须在此相反。您的代码会打印“您打开箱子”九次，但您只需添加一把剑和一把钥匙。根据您的描述，我假设您想要这样做：

print("You opened a chest")
for x in range(9):
    inventory.append("sword")
    inventory.append("key")

或一行

inventory += ['sword','key']*9
