Understanding code and being able to write it yourself are two different things. You can't do the latter without knowing the former. I suggest you read up on the samp wiki and pawn language guide (****** pawn_language.pdf) and read through some existing scripts, try to understand what some pieces do, and alter them to see the outcome. You'll find yourself being able to understand code quite fast. (actually coding, and coming up with creative ideas to do it comes later).
