PhysFS 和 Python 嵌入

Question

I am writing a game engine and I'd like it to have Python scripting as well as support for mods using PhysFS.

My game data is stored something like this:

• /
  • native
    • scripts
    • sprites
    • ...
  • mods
    • mymodname
      • scripts

What I want is for the mod scripts to be able to 'import' the native scripts as if they were in the same directory. Is something like that possible using PhysFS?

Answer 1

You could create a symbolic link so that you can link those files/folders are in a higher directory, with PhysFS you can do:

PHYSFS_permitSymbolicLinks()

Then have PhysFS follow your symbolic links, hope this help:-)

EDIT: What I would do is symbolically link /mods/scripts to /native/mods-scripts so that /native/scripts can call mods-scripts (which actually points to /mods/scripts)

Answer 2

[ I am the same person who asked the question. ]

The solution I used eventually was to modify Python's sys.path when my program starts. This does not pollute the game's data directories with symbolic links and is overall much cleaner.
