Hello Melira,
If you are still having trouble understanding the various GE actor types, go to the GE file menu under Help. Choose "Documentation". After the documentation loads, select the link on the left under "Main Menu" for "Add Actor". This link will lead you to documentation on how "Normal, Canvas, Region, Filled Region, and Wire Frame" actors are used in GE.
Game Editor is a very elegant program. It takes some time to learn it, but you will find that it gets easier as you work with it. You don't really need to know any programming language to use GE. If you get stuck there are some very good programmers here. Just post your questions and the chances are good that someone will have an answer.
If no one answers, you can always count on Makslane, and he is a programming god!
HTHs...
