Minecraft Forums

I have absolutely no experience with this kind of programming. The best I can do in terms of programming is python. I have google drive installed on my mac as a folder that syncs, and I want to make minecraft be able to open a world saved in this directory as well as in ~/Library/Application Support/minecraft/saves. I want it to still have it open folders from there, but also be able to open a single player world from google drive. I want to be able to play on my single player world from two computers at the same time. Is there a simple way to access the code and change the directory, or even better, a mod that already does this?

Thanks.
