[AVM2] How to add string and refer to it?

[CrazyJani]

For example:

      callproperty        QName(Namespace("_var"), "_b6"), 1
      pushstring          "/credits/add?"

callproperty refers to www,realmofthemadgod,com so the full url in this method is www,realmofthemadgod,com/credits/add?

I need a string for custom url, but I have no idea how to add it also I don't know how to refer to it :P
Maybe @nilly can help me?

pop
pushstring "customURL"

Place following the callproperty instruction.

Isn't that like creating a new customURL, not replacing

It is creating a new one. Get rid of the old one, make and use new one, profit. Some people also view this as replacing.

BTW I'm not sure if I understood the question correctly. If not, let me know.

It sometimes show up in the AS3 sorcerer saying some codes are not popped, I don't understand what that means, so I just added a pop in front of the pushstring and I thought it would be like create a new method or something.

Sometimes like this

pop
pushstring "asdasdasdasd"
setlocal 10

changing max local to 11
and it works, so I thought this would be like creating a new thing.

I didn't know that by just doing customURL u can get a customURL method xD

You are confusing terms around. All you are doing is playing with the stack. When avm2 calls a property and it has a returns a value, that value is pushed onto the stack. pop simply removes that value from the stack. When you pushstring, you are then pushing a string to the stack. Since I assume the callproperty returns a string object, pop'ing and replacing that object with another string is a way to circumvent the results of the callproperty instruction. As you see here, you aren't creating any new methods, just simply manipulating data.

Thanks, @nilly, that worked, but another problem appeared:

How do I refer to player being in specific map outside of player.class.asasm?

Oh, so if I pushstring on a stack before, pop removes the string on that stack?
and then I pushstring and it adds a new one, simply like replacing it?

Yes, you got it.

It depends on where you are at and what variables you have access to. What class you editing?

nilly, if rabcdasm as AVM2 bytecode is one option to edit the swf, what's another option? C++?
I want to know because I want to see if there is another way to edit swfs

[nilly]

There are plenty of ways to edit the swf you just have to find them. Personally I rarely work with bytecode anymore. I'll do little things in it but for big stuff I edit the client in as3. Much easier. It's sort of a trade secret though. You'll have to stumble along and figure out how I do that yourself.
