Pygame - Background不工作

Question

我很难在pygame中迈出我的第一步。我只想在jpg背景前移动一张图片。

我在谷歌上搜索了几次，尝试了不同的方法。这是我能想到的“最近的”：

(但它仍然不起作用。)

有什么想法吗？

提前感谢！

import pygame

pygame.init()

display_width = 1600
display_height = 900

black = (0,0,0)
white = (255,255,255)
red = (255,0,0)

Player_width = 73

screen = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption('A bit Racey')
clock = pygame.time.Clock()
background = pygame.surface(screen.get_size())

PlayerImg = pygame.image.load("C:\python\warrior1.png")
background_image = pygame.image.load("depositphotos_159346790-stock-photo-
forest-and-stones-2d-game.jpg")

background.blit(background_image)
screen.blit(background (0,0))

def Player(x,y):
gameDisplay.blit(PlayerImg,(x,y))



def game_loop():
x = (display_width * 0.45)
y = (display_height * 0.8)

x_change = 0
y_change = 0

gameExit = False

while not gameExit:

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            gameExit = True

        if event.type == pygame.KEYDOWN:
            [...]

    x += x_change
    y += y_change

    Player(x,y)

    if x > display_width - Player_width or x < 0:
        gameExit = True

    pygame.display.update()
    clock.tick(60)

game_loop()
pygame.quit()
quit()

Answer 1

答案：

在while循环中，

• 删除用screen.blit(background_image, (0,0))
• add background.blit(background_image) screen.blit(background (0,0))替换background = pygame.surface(screen.get_size())
• in player和screen.blit(background_image, (0,0))
• add screen.blit(background_image, (0,0))替换
• gameDisplay

Pygame的有用提示：

查看错误消息并发布它们。

在pygame中使用*.png文件。它们可以是透明的。当图片重叠时，您看不到边缘。
