Question

我正在pygame中制作“鸭子狩猎”游戏。我已完成所有工作，需要时我的精灵会移动并重新生成，单击时光标会变成带有声音的十字准线等。我遇到的问题是试图在鼠标单击鸭子时添加点。知道我该怎么做吗？发布所有代码，直到我感谢您工作之前，有点混乱，请专门检查主循环。谢谢。

pygame.sprite.spritecollide仅将精灵作为第一个参数，将精灵组作为第二个参数。要检查鼠标是否与鸭子碰撞，可以使用for循环遍历duck_list并调用当前鸭子的rect的collidepoint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
