tmx - 将 hd TMX Tilemap 转换为 sd，我应该手动执行此操作吗？

Question

我有一个 960*640 像素的瓷砖地图，使用 64*64 瓷砖进行高清视网膜显示。现在，我需要一个用于 sd 显示的 tilemap。（我猜它应该是 480*320 像素，使用 32*32 tile）

那么，有没有简单的方法呢？

在 Mac 应用商店中查找“Unretiner”等工具。

'hd img -> sd img' by Unretiner
'hd tmx -> sd tmx' by ??

感谢你。

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>
