Hi eric, so unfortunately currently there isn't any MoI-specific tutorials and such for script writing. To do it basically requires studying existing scripts and figuring things out from that.

There is some very minimal information and a few links here: http://moi3d.com/wiki/Scripting

At some point in the future I expect to do a lot more work to make both using and learning MoI scripting a lot easier than it currently is, but there is a lot of time consuming work involved in doing that and it hasn't yet risen to the top of my priorities yet. I'm still a lot more focused on more "regular end user" things rather than "power user scripting" type stuff as of yet.

One thing that can help is if you get familiar with the JavaScript language - that's the language that MoI uses for scripting. There is quite a lot of general information out there on the web on JavaScript since it is the main language used by web browsers for doing scripting in a web page. So doing a search for something like "html javascript tutorials" can get you some stuff for getting started on JavaScript putting it in a web page to start with. For example: http://www.w3schools.com/js/
