python - 如何创建多个相似的 Sprite ？

Question

让我向您展示可能有助于使这个问题更有意义的代码。

import pygame, classes, random
pygame.init()

screen = pygame.display.set_mode((640, 480))

def game():
    pygame.display.set_caption("GOLOGO")

    laser = classes.Laser(screen)
    player = classes.Player(laser, screen)
    bad = classes.BadGuy(screen, 320, 0)
    bad1 = classes.BadGuy(screen, 260, 0)
    bad2 = classes.BadGuy(screen, 200, 0)
    bad3 = classes.BadGuy(screen, 140, 0)
    bad4 = classes.BadGuy(screen, 80, 0)
    bad5 = classes.BadGuy(screen, 20, 0)
    bad6 = classes.BadGuy(screen, 380, 0)
    bad7 = classes.BadGuy(screen, 440, 0)
    bad8 = classes.BadGuy(screen, 440, 60)
    bad9 = classes.BadGuy(screen, 320, 60)
    bad10 = classes.BadGuy(screen, 260, 60)
    bad11 = classes.BadGuy(screen, 200, 60)
    bad12 = classes.BadGuy(screen, 140, 60)
    bad13 = classes.BadGuy(screen, 80, 60)
    bad14 = classes.BadGuy(screen, 20, 60)
    bad15 = classes.BadGuy(screen, 380, 60)
    space = classes.Space(screen)
    scoreboard = classes.Scoreboard()

    allSprites = pygame.sprite.OrderedUpdates(space, laser, player)
    badSprites = pygame.sprite.Group(bad, bad1, bad2, bad3, bad4, \
        bad5, bad6, bad7, bad8, bad9, bad10, bad11, bad12, \
        bad13, bad14, bad15)
    scoreSprite = pygame.sprite.Group(scoreboard)

如您所见，有很多 BadGuy Sprite 。它们只是在不同的位置。我不介意继续使用这种方法，但我希望有一种更简单的方法可以做到这一点。我可能会在增加屏幕尺寸的同时添加更多。我正在使用 python 3 和 pygame

您可以将值存储在列表中:

coordinates = [(320, 0), (260, 0), (200, 0), ...]

并在创建时循环遍历它们。您可以将实例放入字典中:

badGuys = {}
for i, v in enumerate(coordinates):
    badGuys["bad%d"%i] = classes.BadGuy(screen, *v) 

希望这对您有所帮助!
