I am delighted it works for you! Being open-sourced, I thought more users on the forum would be using Blender but I haven't had much response with these two add-ons, even on Blendernation!
One of the hardest issues with 'spots', whether video or user-interaction, is locating them on the screen.
This was suppose to provide co-ordinates that can be pasted into the code. (hence the litte 'script' box) but it is probably bad now.
I haven't seen a basic Dagon example that we can use to kick-start us users with a basic setup. Right now I'm not sure of the easiest way to make my add-on useful in the current Dagon.
LUA vs Python: Yes, I bought a whole book to study LUA, then it was dropped, then it was brought back. Python seems to be a popular scripting language so it is nice to apply experience everywhere. Programming for Blender is a lot of fun!
I was impressed with LUA's promise though, since it was designed for non-programmers (we've heard THAT one before) and seems like a very concise language.
