今天我尝试在 pygame 中制作一个小平台游戏。我使用了一个非常漂亮和有用的教程中的很多代码，因为我不知道该怎么做。
到目前为止，通过处理屏幕的 32x32 部分并根据地图文本部分中的字符为其分配块类型来制作地图。到目前为止，我有一个平台块、一个边界块和一个出口块，我希望最终使游戏加载一个新的关卡。
我的问题是：如果我“通过关卡”并想让游戏加载一张新地图，我该怎么做？我试过从组中删除精灵，但我没有任何运气。我已经尝试了一段时间，但我有点气馁。
这是代码：
import pygame
import math
from pygame import *
DISPLAY = (800, 640)
DEPTH = 32
FLAGS = 0
def main():
pygame.init()
screen = display.set_mode(DISPLAY, FLAGS, DEPTH)
display.set_caption("Square2")
timer = time.Clock()
up = down = left = right = False
bg = Surface((32,32))
bg.convert()
bg.fill(Color("#000000"))
entities = pygame.sprite.Group()
player = Player(32,32)
platforms = []
x = y = 0
level = [
"PPPPPPPPPPPPPPPPPPPPPPPPP",
"P P",
"P P",
"P P",
"P P",
"P P",
"P P",
"P P",
"P P",
"P P",
"P P",
"P P",
"P pp P",
"P P",
"P P",
"P pppppp P",
"P P",
"P pppppp P",
"P P",
"PPPPPPPPPPPPPPPPPPPPPPPPP",
]
#builds the level
for row in level:
for col in row:
if col =="p":
p = Platform(x, y)
platforms.append(p)
entities.add(p)
if col == "E":
e = ExitBlock(x, y)
platforms.append(e)
entities.add(e)
if col == "P":
P = Border(x, y)
platforms.append(P)
entities.add(P)
x += 32
y += 32
x = 0
entities.add(player)

timer.tick(60)
