使用 pygame 加载图片

Question

这是我的背景网格的代码

Background = pygame.display.set_mode((900 ,900))
Green = (45,198,14)
Background.fill(Green)

for i in range(0, 900, 50):
    pygame.draw.line(Background, (0, 0, 0), (0, i), (900, i))
    pygame.draw.line(Background, (0, 0, 0), (i, 0), (i, 900))
pygame.display.update()

while pygame.event.wait().type != pygame.QUIT:
    pass

我无法将任何图像加载到它上面，我是否必须将其转换为 n 个图像，然后再转换为 sprite，或者我有没有办法将图像加载到网格上。我试过使用 blit 函数，但它不会将图像放到网格上。

RedInfantry= pygame.image.load("H:\computer science.2\Coursework\Week\Red team\InfantryRedV20.gif").convert()


while True:
    Background.blit(RedInfantry,(0,0))

如果我将图像变成精灵，它是否允许我移动和删除网格上的图像？我是否必须在图像中创建网格才能将其他图像复制到它上面。

创建一个网格：

grid = [[None for i in range(0, 900, 50)] for j in range(0, 900, 50)]

将图像分配给网格中的字段。例如：

grid[3][2] = RedInfantry

在应用程序循环中绘制网格中的图像：

for i in range(len(grid)):
    for j in range(len(grid[i])):
        x, y = i * 50, j * 50
        image = grid[i][j]
        if image != None:
            Background.blit(RedInfantry,(x, y))

此外，我建议在主应用程序循环中连续绘制整个场景：

import pygame 
pygame.init()

Background = pygame.display.set_mode((900 ,900))
Green = (45,198,14)

RedInfantry = pygame.Surface((50, 50))
RedInfantry.fill((255, 0, 0))

grid = [[None for i in range(0, 900, 50)] for j in range(0, 900, 50)]
grid[3][2] = RedInfantry

run = True
while run:
    # handle events
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    # draw background
    Background.fill(Green)

    # draw scene
    for i in range(0, 900, 50):
        pygame.draw.line(Background, (0, 0, 0), (0, i), (900, i))
        pygame.draw.line(Background, (0, 0, 0), (i, 0), (i, 900))
    for i in range(len(grid)):
        for j in range(len(grid[i])):
            x, y = i * 50, j * 50
            image = grid[i][j]
            if image != None:
                Background.blit(image,(x, y))

    # update dispaly
    pygame.display.update()
