python - 如何制作墙贴图？
问题描述
我正在制作游戏，但我想通过添加墙来使游戏更难。我发现它叫做瓷砖地图。但它有多种颜色，我只想要一种颜色，灰色。我希望它像1,1,1,1,
1,0,0,1,
1,0,0,1,
1,1,1,1
0 = 没有。1 = 灰色矩形。我也需要它像WIDTH = 16
HEIGHT = 9
TILESIZE = dw/WIDTH
但我找不到实现它的方法。
我尝试使用 def 代码，但它落后于我的游戏。我尝试使用这个网站：http ://usingpython.com/pygame-tilemaps/

解决方案
如果您已经在代码中有问题并且您的链接中有示例，我不明白您为什么会遇到问题。
tilemap = [
[1,1,1,1],
[1,0,0,1],
[1,0,0,1],
[1,1,1,1]
]
MAPHEIGHT = 4
MAPWIDTH = 4
TILESIZE = dw/MAPWIDTH
GREY = (128,128,128)
for row in range(MAPHEIGHT):
for column in range(MAPWIDTH):
if tilemap[row][column] == 1:
pygame.draw.rect(screen, GREY, column*TILESIZE, row*TILESIZE, TILESIZE, TILESIZE))
编辑：
你有问题，因为你在错误的地方使用它。您必须在screen.fill（清除缓冲区）和pygame.update（将缓冲区发送到视频卡并将其显示在屏幕上）之间进行绘制
screen.fill(white)
for row in range(HEIGHT):
for column in range(WIDTH):
if tilemap[row][column] == 1:
pygame.draw.rect(screen, grey, (column*TILESIZE, row*TILESIZE, TILESIZE, TILESIZE))
# ... draw other things ...
pygame.display.update()
你的代码很乱。你应该有
- 您更新值、移动对象、箱子/重新生成对象、加载/保存泡菜等的地方，但不要在那里绘制。
- 您使用的地方
screen.fill，绘制所有元素，使用pygame.display.update但不更新对象并且不加载/保存泡菜
