AS3 SWF Editing / Altering packet structures

[Keiz]

Hey y'all.

I have a question, only respond to the question if you know what I mean. ( No I'm not searching for Flash Decompiler )

Say I hypothetically want to alter a packet's structure, I want an int converted to a string. I'm obviously familiar with AS3 Sorcerer, I can see the code I want to edit, yet I simply can't. AS3 Sorcerer is read-only.
Does anyone have software to change AS3 code of a Habbo.swf?

Thanks in advance!

Use rabcdasm to decompile and recompile the swf file.

Ye I did try that, but it doesn't quite output AS3

[The General]

No because it outputs Actionscript Byte Code

Its the only way. Yes its possible but you gotta know what you're doing.
And no I don't know as I am not familar with ABC.

The decompiler I use, JPEXS Free Flash Decompiler, has an experimental feature that lets you alter ActionScript in ActionScript language.
Otherwise ABC is the only way.


I tested it out by adding a 'userId' to the disconnection/logged out packet (this packet redirects client to specific 'logged out' page).
Seems to have worked.

Wow! Ironic I asked not for such Flash Decompilers.. I will look into this, thanks

It's the only thing I have found which is what you are asking for ( even though you hate decompilers? )
Feel free to PM if you want help, but I assume you know what you are doing based on what you asked to do.

Thanks! Yes I altered the extendedProfile packet in both swf and emulator, and added an XML layout for it..
Disconnects for now but does show what I want!

Spoiler:

Note the screen is taken just before disconnection. So it must have something to do with the relationships parser.
But thanks for sure, this is what I was looking for

[The General]

Oh wow. That opens up the possiblity for so much more @Beny.

*cough* snowstorm *cough*

Now all I want is a proper IDE. I tried decompiling and opening with FlexBuilder but that sucked.

Check the disconnect reason in the console of your browser.

Let's make one :-)

We are already two steps ahead of you.

Many great things can come from this, for sure.

In the revision I use, header 3760 is actually the GetRelationshipsMessageComposer
I'm not sure what would cause such an error, but I did change the RelationshipsComposer to a static packet with count 0 sent, even that disconnects me. Even not-sending the packet disconnects, quite odd.

Do you have debug function on your FlashExternalInterface?
This may return more info.

Well, you're not alone. When I alter a structure, I get "failed to parse incoming message" although I've done everything as Sulake have done

When I find out fully how to alter packets, I'll write a tutorial :-)
