Thank you for your speedy replies !! Yup, i don't have a lot of programming experience, and it is the very first time experience in game programming. I have dream of reconstructing an online game, called "LifeStorm 2" by a Japan company, that I played 10 years ago, and I finally found this engine, is very similar to that game. I am able to understand, or interpret some easy game logic. Anyway, EO is fantastic starting point for me. It is only the second day I work with EO. It is quite difficult to identify which part of script I should work on since there is a lack of descriptions. EO is still great though.
