you should follow all the tutorials\missions, really, and if you didnt understand, do the tutorial a second time...
it really helps..
but if you preefer to ask here, tell us what you want to do exactly. explain an example game that i could tell you how to make it... and i will explain how it works.. the commands are easy and should be a matter of trial and error for learning...
i am good with the commands, i am just bad at making the games.. i have 0 ideas on a design..
make an example game, and tell me what you are trying to do, or what you want.. i will explain how to achieve that and you can that for learning..
