So here is what I'm trying to do. I have a Unity 3D project for my reusable code. And I want to add this to my other projects that I house in git.
So let's say I have a project 'foo'.
I want to clone foo and then add my reusable scripts as a sub-module;
then I want a symbolic link to the folder that contains all the reusable scripts in my sub-module and one that exists in project foo's asset folder.
So when I make a change in my project, I could push my changes to my sub-module project.
This is probably very confusing, please let me know if I need to be more specific and I will try to do better.
It is best to separate the two environments:
the git clone one, where you have foo and foo/script submodule:
git clone foo /url/of/foo git submodule add /url/of/script git add . git commit -m "Add script as submodule of foo" git push
the working environment, where you set your symlinks to foo and script scripts.
cd somewhere/else ln -s /path/to/foo/file1 ln -s /path/to/foo/scripts/scrip1 ...
That way, once you have modified scripts, you can go back in foo, and do a
git push --recurses-submodules=check, in order to make sure you have added/push both foo/scripts and foo.
