python - Pygame 移动 Sprite 上的鼠标点击检测

Question

我正在 pygame 中制作一个“猎鸭”游戏。我一切正常，我的 Sprite 在需要时移动和重生，光标是一个十字准线，点击时会发出声音等。我遇到的问题是尝试在鼠标点击鸭子时添加点。知道我该怎么做吗？发布了所有代码，在我得到感谢工作之前有点困惑，具体检查主循环。谢谢。

pygame.sprite.spritecollide仅适用于 Sprite 作为第一个参数和 Sprite 组作为第二个参数。要检查鼠标是否与鸭子碰撞，您可以使用 for 循环迭代 duck_list 并调用 collidepoint当前鸭子矩形的方法:

if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
    for duck in duck_list:
        if duck.rect.collidepoint(event.pos):  # event.pos is the mouse position.
            score += 100
