Well, it is still a LOT of work to get from just having this script to actually having a game that you can save in. But, never fear, a tutorial comes with em! In less than an hour, if you know what you are doing, you should be able to get things working. Some updates I have for the future will be support for multiple save files, and support for more than one level. Right now, it’s still the best save system around for blender games.
If you have any problems with it, and want to yell and scream at me, feel free to do it here, I haven’t thourouly tested it (made a few changes from pooland scripts to make it more general) but I didnt change too much. Chances are I made a really stupid mistake somewhere. If you really cant get the hang of my tutorial, you can send my your blends, and I could try and get saving working in them.
Good luck fellow blenderers!
