使用pygame加载图像

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，我必须将其转换为n个图像，然后使用精灵，或者有没有办法将图像加载到网格上。我尝试过使用blit功能，但它不会将图像放在网格上。RedInfantry= pygame.image.load("H:\computer science\6.2\Coursework\Week\Red team\InfantryRedV20.gif").convert()while True:    Background.blit(RedInfantry,(0,0))如果我将图像转换为精灵，它会允许我移动和删除网格上的图像吗？我是否必须在图像中创建网格以将其他图像放大到它上面。我想使用的步兵图像

Answer 1

将以下网格打包：

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

在应用程序循环的网格中绘制图像：

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()
