hey! i have recently started making a game with a friend on unity, but its really hard to share the code. right now we just send the project file back and forth thru skype. but this means only one of us can code or test something at a time. is there any better ways other devs know so we can both code and work on the same file or something better.

Also, most free version control hosts are limited to open source projects. If you want to keep your stuff private you'll need a private hosting provider. One of the site's partners, Assembla, offers 1GB of private hosting for free. Scroll to the bottom of any page and pick the Assembla link for more info.

if you decide for SVN, and you are working under Windows, check out tortoise SVN. It is one, if not the best SVN Client for Windows, and is neatly integrated into the Windows Explorer (I know, some people don't like that, so might be just me that likes that a lot).

Make sure you read into how to use it, and make sure you and your pal both agree on guidelines. Merging back file changes done synchronously can be a HUGE pain (depending on where in the file the changes are... if both changed different lines, the merge might be completly automatic (though the tool will of course not be able to check if the file still compiles, for example)).

A good practice, if you don't want to access the same files at the same time, is to activate file locking, which makes SVN prevent others from commiting changes to files you have locked to work on them.

But I am going to far now, guess this is getting to advanced :)
