我正在做一个吃豆人游戏,目前我的基本知识正在起作用,但是在吃完它们后,我无法重新生成pac颗粒。目前,我已经设置好了,吃了pac颗粒后,将其从pacpellets列表中删除。当列表为空时,将其重新装满,然后告知将所有pac颗粒重新绘制到屏幕上。它遍历了所有正确的功能和所有内容,我已经检查了打印语句,但是pygame.draw.rect不起作用,我不知道为什么。

最佳答案

我将执行以下操作:定义一个函数,该函数创建一个精灵组并将其填充为颗粒精灵,然后将其返回并分配给主函数中的变量。当pellets组为空时,只需再次调用此函数,然后将新组分配给旧变量,颗粒就会再次出现。

import pygame as pg

        super().__init__(*groups)

        self.image.fill(pg.Color('yellow'))
        self.rect = self.image.get_rect(center=pos)
        self.vel = pg.math.Vector2(0, 0)
        self.pos = pg.math.Vector2(pos)

    def update(self):
        self.pos += self.vel
        self.rect.center = self.pos

        self.image.fill(pg.Color('turquoise'))
        self.rect = self.image.get_rect(center=pos)


def create_map():
    """Create a sprite group filled with Pellet sprites."""
    group = pg.sprite.Group()
    for i in range(10):
        group.add(Pellet((50, 20*i+50)))
    return group
