python - Pygame.spritecollide() 检测 Sprite 之间的碰撞，即使它们没有接触

转载作者：行者123 更新时间：2023-12-01 01:28:50

我在网上没有找到类似的问题。我希望 pygame 能够检测到玩家何时与另一个 Sprite 碰撞，例如箱子或其中一个怪物，但它会检测到玩家正在与它们碰撞，即使它们没有接触，还要注意这不是 100%时间，只是在某些领域他们发生了碰撞。

我的目标是让游戏检测到玩家何时触摸怪物，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。还希望箱子在接触玩家时向 inventory[] 添加剑和 key ，但仅限一次。我做到了，但是当你靠近它时，它会打开箱子，而不是当你触摸它时，与怪物一样。

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

这是我的代码:

最佳答案

玩了一下(双关语!):您没有设置胸部的 Sprite 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，但它会针对更大的整个图像进行检查。

如果将其显式设置为 32x32，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显示它的大小仍然是99x99，即图像本身的大小。 (我没有测试，但你的玩家 Sprite 可能有同样的问题，因为你以相同的方式构建它。)

要使其在您在附近时打开，请更改其 rect.x、rect.y、rect.width 和 rect.height 到一个更大的矩形。

Also want the chest to add a sword and key to inventory[] when touching the player but only once.

    inventory.append("sword")
    inventory.append("key")

或单行

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