Need help with starting modding

Hello there,
I want to start modding. I have Sublime text as program to code, so I don't need help with picking editor.
I want to know how to start modding, because when I look at code of ex. archer... Jesus christ. I was learning some C++, but I forgot most of them...

Well, my friend tell me how he started modding - he was changing variables in .as files, then he was checking what was changed.

Can you give me tips about how to start modding fast and good? I want to know:
-How modificate Sandbox mode to modding-friendly mode;
-Is there a way to check if mod is programmed fine without doing Close-Open, Close-Open a game?;
-Variables and what they are doing I checked a .../KAG/Manual;
-Simple codes and if you can - place descriptions between codes;
-How YOU started modding - I will propably do same as you;
-More and more...

My main point is to make a Rogue class. Yes, I know what this class will have.

Thank you for all help.
Btw, sorry for my english =)

 

- If you want to modify sandbox, go under the Base/Rules/Sandbox/Scripts/Sandbox_Rules.as, you will find sandbox specific scripts there, and you can make a copy inside your mods to modify it.

- I believe there was a way, but I've been told a while ago it was broken. So I'll guess no, but I'm not sure.

- KAG manual doesn't only have variables, it has alooot of functions, which are what you're going to be using to script, obviously. I wouldn't worry about the variables, as long as you know what string, vec2f, int and float are.

- For simple codes, I just think you should hop on to #kag.modding on IRC, I don't think there's any easy code without explaining.

- I started with the worst codes ever, which is Bomb.as and the GUI stuff, which is a pain to understand, but after that, everything seems easy. Basically just know how to code in C++ and then ask on the IRC.

Thank you!
I was joining modding IRC but nobody answers, nvm, will try again!

 

Yeah, you need to have alooot of patience for answers, sometimes it takes a day, sometimes it's instant.

 

And one question, how much time it took to make a something simple (without graphics) ex. Golden drill?

 

1 to 10 minutes depending if you fuck up or not, if you just change existing parameters it's super easy.

Edit: and not really "appreciated" by anyone, since it's so dull.
