Pygame敌人不会向下移动-塔防游戏

如何解决Pygame敌人不会向下移动-塔防游戏

我的问题是，在我的塔防游戏中，我的敌人的最后2个检查点，敌人不会倒数第二次走下去，直到他们损坏了塔video，他们才向前前进，为什么他们只是从那里出来
最后一个是一样的

    # move the enemy
    for spider in spiders:
        if spider.x < 230:
            spider.x += spider.speed


            
        elif spider.y < 160:
            spider.x += spider.speed
        elif spider.x > 540:
            spider.y -= spider.speed
        elif spider.y < 566:
            spider.y += spider.speed
        elif spider.y > 290:
            spider.x += spider.speed

        elif spider.y > 566:
            spider.x += spider.speed

        # THIS part isnt working IDK why if the enemy is close to the 4th check point it should go down but it wont??
        elif spider.x < 628:
            spider.y += spider.speed

        # idk if this part will work because the last second part didnt work
        elif spider.y < 550:
            spider.x += spider.speed

解决方法

一位YouTuber Tech With Tim在12小时livestream中用pygame创建了一个塔防游戏。您将在此github-link上找到他的代码，并且可以找出错误的出处。

注意：此github代码中不包含资产，该资产不包含资产（图像和声音），因此您可以创建资产文件夹并在游戏脚本中引用图像和声音。

在查看您的代码时，我注意到了这种奇怪情况

elif spider.x > 540:
    spider.y -= spider.speed

...

elif spider.x < 628:
    spider.y += spider.speed

这是基于您提供的订单。第二个elif永远不会运行，因为蜘蛛永远不会运行-x表示我们将永远无法获得 540始终为真，这也意味着由于Elif始终运行第一个真实条件，因此我们无法实际获取将导致条件 540之前运行的值。我建议修改代码，以通过将self.checkpoint添加为每个蜘蛛的属性来消除这种情况的可能性。然后，当到达检查点时，请检查是否存在

elif spider.x > 540 and (spider.checkpoint = 3 or spider.checkpoint = 4):
    if spider.checkpoint != 4:
        spider.checkpoint = 4
    spider.y -= spider.speed

对于每个检查点，它将在第一次运行时将其递增到下一个检查点，并保持在那里，以便在到达下一个检查点时，只需将每个数字加1，以便蜘蛛程序始终知道其要行驶到的检查点。 / p>

我建议将蝎子沿点列表（setState()）移动。使用声明下一个点（spider_move）索引的变量，并将蝎子移动到该点（spider_move_to）。每次到达一点时，然后增加索引（next_p）。如果列表中没有其他点，则停止运动。要移动蝎子，请计算spider_move_to += 1当前位置和列表中的点（dx）之间的差（dy，spider）。根据{{​​1}}和next_p的数量，将蝎子（spider.x，spider.y）的位置增加或减少spider.speed：

dx

---

如果您有多个蝎子，那么我建议将dy设为类spider_move_to = 0 spider_move = [ (240,330),(240,550),(540,160),(770,(870,550)] runninggame = True while runninggame: # [...] if spider_move_to < len(spider_move): next_p = spider_move[spider_move_to] dx,dy = (next_p[0] - spider.x,next_p[1] - spider.y) if dx > spider.speed: spider.x += spider.speed elif dx < -spider.speed: spider.x -= spider.speed else: spider.x = next_p[0] if dy > spider.speed: spider.y += spider.speed elif dy < -spider.speed: spider.y -= spider.speed else: spider.y = next_p[1] if spider.x == next_p[0] and spider.y == next_p[1]: spider_move_to += 1 # [...] 的属性

spider_move_to

使用属性代替全局变量：

spider
