Question

我一直在尝试使用python和pygame模块创建mario类型的2d侧滚动平台游戏。我使用了来自programarcadegames的教程来编写平台和播放器的代码，但我只是想不出如何实现以特定x和y坐标生成的敌人并将它们添加为可碰撞的精灵（这会“杀死”一个玩家）点击）？

教程代码如下：

我曾尝试为敌人的精灵创建基本类，并使其前后移动，但定位是我的主要问题。

这是我的代码：（水平滚动时敌人确实会出现一点故障）

class Enemy(pygame.sprite.Sprite):

    def __init__(self):

        super().__init__()

        width = 30
        height = 30
        self.image = pygame.Surface([width, height])
        self.image.fill(BLUE)

        # Set a reference to the image rect.
        self.rect = self.image.get_rect()

        # Set speed vector of player
        self.change_x = random.randint(3, 4)
        self.change_y = 0

    def update(self):

        self.rect.centerx += self.change_x
        if self.rect.right <= 0 or self.rect.left >= 100:
            self.change_x *= -1

对于与播放器的碰撞，我建议您这样：

“敌人”必须是一个精灵组。要创建一个精灵组：

#in your gameloop
playerEnemyCollision = pygame.sprite.spritecollide(player, enemies, False)

要创建一个新的敌人并将其添加到组中，只需键入：

#outside your gameloop
enemies = pygame.sprite.Group()

现在您可以使用以下方法检查碰撞情况：

#outside your gameloop
en = Enemy()
en.rect.x = XX #set your Enemies x-Position
en.rect.y = YY #set your Enemies y-Position
en.add(enemies) #adds the enemy "en" to the sprite-group "enemies"

在大多数情况下，改变精灵的位置以使其超出“敌人级”之外的正常移动并不是一个好主意。希望我能帮助您解决您的问题。 Twistios
