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，我必须将其转换为n个图像，然后再转换为精灵，或者有没有办法将图像加载到网格上。我试过使用blit功能，但它不会将图像放到网格上。

RedInfantry= pygame.image.load("H:computer science6.2CourseworkWeekRed teamInfantryRedV20.gif").convert()

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

如果我把图像变成精灵，它会允许我移动和删除网格上的图像吗？我必须在图像中创建网格才能将其他图像闪电式地复制到它上吗？

我想使用的步兵图像

Answer 1

板条箱一个网格：

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

将图像指定给网格中的字段。例如：

grid[3][2] = RedInfantry

在应用程序循环中的网格中绘制图像：

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()
