LÖVE

Hi! I'm relatively experienced with coding, (C, Objective-C, Lua, Python, some C++, Java, etc.), but I've only every worked casually and solo. Consequently, I'm not very familiar with versioning systems and repositories.

I'm trying to slightly modify Love to expose some basic 3d transformation functions for my own development purposes, and I'm facing the harsh reality that I actually have no idea how to compile Love, even unmodified.

I installed Mercurial, "hg clone"-ed the repository, and opened the Xcode project. Nearly all of the dependencies in the frameworks folder were in red, which I'm guessing means Xcode is looking for them but they're not installed on my computer. I'm wondering what I'm doing wrong and, more generally, what resources you'd recommend to learn the ins and outs of working with a repository like Love so I can make the modifications I need. Thanks in advance!

You can download the dependencies for OS X here: https://love2d.org/sdk/love-osx-frameworks.zip
Put them all in /Library/Frameworks/ or a similar place, and the LÖVE xcode project should automatically recognize them.

You could try your hand at SourceTree to potentially make it easier to use Mercurial. Also take a look at the Forking tutorial for Bitbucket.
