I just now made build 365, which seemed as good a number as any to mention.
One way I’ve improved the development process is to have an easy way to post a copy of the game for the rest of the team to test. With King of Dragon Pass, this was basically a manual step. Now, there’s a script that increments the build number and does a clean build, then copies it to a web site. It also uses rsync to copy any script files to a Dropbox folder, so QA has easy access to the corresponding source.
This isn’t build automation (it’s not automatic, like Travis or buddybuild), but it’s painless. The basic build takes about 40 seconds (uploading is more variable). And it does mean we pass one of the steps in the Joel Test. Our builds aren’t daily (since we’ve been at this more than a year), but they are at least frequent.
