No one can really give you a guide on how to make a game with RM2K(3). It would be extensive and extremely long and confusing. You should go to
www.gamingw.net for tutorials on a specific area in RM2King. How I learned was by messing around with the program a bit. And as time went by, I grew more and more knowledge on how to make a game. Believe it or not, I just started using the program about a month ago. And my game's coming along pretty well. There is a Help option in the program, try looking at that. The things you are asking for are basic stuff. I really recommend looking at the tutorials at gamingw.net. They have MANY!
