Hi Bravlin, MoI does not currently have any built in developer environment, you just use a text editor to write the files and use moi.ui.alert('text') to pop up messages to help you see what is going on.

Also set the option in moi.ini to disable file caching so it will reload scripts every time they are run, to find that go to http://moi3d.com/wiki/Scripting and go to the link that says "See here for info on disabling file caching so commands will reload on every run".

I would like to work on having an integrated script debugger built in to MoI in the future but it will be a highly time consuming thing to work on so I'm not sure when that will happen.
