将高清 TMX 瓦片图转换为 sd，我应该手动执行此操作

Question

我有一个 960*640 像素的瓦片地图，使用 64*64 块瓷砖进行高清视网膜显示。现在，我需要一个用于 sd 显示的瓦片地图。（我猜应该是480 * 320像素使用32 * 32瓷砖）

那么，有没有简单的方法可以走呢？

在Mac应用商店中查找"Unretiner"之类的工具。

的"hd img -> sd img"HD TMX -> SD TMX" by ？？

谢谢。

这是我用来从hd .tmx生成sd .tmx的Python脚本。您可以通过以下 shell 命令使用它。

>python change_tmx_numbers.py <directory_which_contains_hd_tmx_files> <output_directory>

脚本：

#!/usr/bin/python

  if path[-1] == '/':
    return path[:-1]

  print text
  pointm = '{(?P<x>-?d+), (?P<y>-?d+)}'
  framem = '{{(?P<x>-?d+), (?P<y>-?d+)}, {(?P<width>d+), (?P<height>d+)}}'
  m = re.match(pointm, text)
  if m != None:
    rt = '{%d, %d}' % tuple([int(f) / 2 for f in m.groups()])
    print 'change %s -> %s' % (text, rt)
    return rt
  else:
    m = re.match(framem, text)
    if m != None:
      rt = '{{%d, %d}, {%d, %d}}' % tuple([int(f) / 2 for f in m.groups()])
      print 'change %s -> %s' % (text, rt)
      return rt
