It's nice to see you did some of the basics. What I suggest, is to check any script on the forum that interests you, and check how it's made. Once you think you understand enough of what is used where, and why, you can try to edit certain parts, and add things to it. This way you can learn to do the bigger stuff while having the fun of playing with functions and ideas.
Once you think you got the hang of it, try making a script from scratch (which means it's build from a new.pwn document, or from a blank document), and make any script you want.
Remember that for questions, just post here
(( Remember that the advice I gave you is based on personal experience. You might find that this doesn't work for you -No problem, I'm sure other people will give advice aswell. ))
There are also quite some tutorials here on SA-MP Forums, you might want to check some of those.
I also suggest you to read the forum rules, if you didn't do that already. If you follow those rules, your stay here might be a little nicer
