Beginner Help with Client Modifying

I'll admit it, I'm pretty shitty with programming in general. I do have the open mindedness to learn though. Is there any sort of point where I can start. Any sort of language I need to know? I already have the 15.0 SWF Decompiled, but what the hell do I do with it?


Sorry if this isn't even a good question, but I haven't done any coding for years now, and I am not familiar with anything flash based.

First of all, this is not flash, this is actionscript 3.

Just learn actionscript 3, or play with mod selector and look at the codes inside and it will help you I think, I'm a noob at coding but still after looking at the code structure and codes I learned a lot xD

Alright I'll do that, I heard about Actionscript 3 having to do in this, but I wasn't sure! Thanks for the advice.

FYI learning as3 will help but rabcdasm doesn't output as3, it is avm2 bytecode. You'll need to learn how to read and write in the latter if you want to modify the client directly.
