我正在尝试在Pygame中制作一个简单的平台游戏，并创建了我想要关卡的基本轮廓。但是，为了移动角色，我需要不断用颜色填充屏幕，颜色与地图重叠。我该怎么办？
我的代码：
import pygame
from pygame import *
import sys
WIN_WIDTH = 680
WIN_HEIGHT = 500
DISPLAY = (WIN_WIDTH, WIN_HEIGHT) #variable for screen display
DEPTH = 32 #standard
FLAGS = 0 #standard
RED = (0, 0, 255)
class Hero():
def __init__(self, x, y):
self.x = x
self.y = y
def appearance(self):
return pygame.image.load('C:\\Users\\admin\\Desktop\\Player1.png')
def move_right(self):
self.x += 10
return self.x
def move_left(self):
self.x -= 10
return self.x
player = Hero(56, 420)
player_img = player.appearance()
x = 0
y = 0
platformx = 0
platformy = 0
WHITE = (255, 255, 255)
pygame.init()
screen = pygame.display.set_mode(DISPLAY, FLAGS, DEPTH)
screen.fill(WHITE)
pygame.display.set_caption("Rum Islands")
timer = pygame.time.Clock()
level = [
"PPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP", #45 x 25
"P P",
"P P",
"P P",
"P PPPPPPPPPPP P",
"P P",
"P P",
"P P",
"P PPPPPPPP P",
"P P",
"P PPPPPPP P",

"P PPPPPPPPPPP P",
"P P",
"P P",
"P P",
"P P",
"PPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP",]
pygame.key.set_repeat(10,10)
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
x = player.move_left()
elif event.key == pygame.K_RIGHT:
x = player.move_right()
screen.fill(WHITE)
for row in level:
for col in row:
if col == "P":
pygame.draw.rect(screen, RED, (platformx, platformy, 40, 20))
platformx += 15
platformy += 20
platformx = 0
screen.blit(player_img, (x, y))
pygame.display.update()
答案 0 :(得分：2)
修改后的代码。
您的问题是platformy，因为您再也没有将其设置为零。
