Im trying to make a hack that makes it so you cannot talk during a game on sc in b.net.. I know that there are 11 offsets and I have found them all. My question is how do I make it so I can freeze them all at once.. Ps im writing the hack in c++

[R.a.B.B.i.T]

Do you want to block text or actually prevent the person from saying anything (or are you trying to block text people said)?

[hierholzer]

keep people from saying anything.. ive tested it with just one offset. it jsut made a blank space. so i figured that if i blocked all 11 offsets then it would prevent people from talking

[R.a.B.B.i.T]

People will still be able to talk.  The offsets are for displaying.  If you want to prevent them from talking to eacher other, you have to have your program somehow remotely block certain packets from being sent by their games.  Good luck with that.

[hierholzer]

yes but if it prevents messages to display then they cant see anything.. or at least thats what I think. I have froze 3 of the offsets at one time and when people talked there would be 3 blank spaces between 2 messages at one time. so if you froze all 11 wouldnt it just make one blank space since theres no offset the words can fall onto?

[DeTaiLs]

This would only stop you from seeing what they say they can still talk and if your making this in c++ u better learn asm because your going to need to jump offsets

[Warrior]

You could theoreticly loop through each offset making sure they don't contain anything or just hack the timer to make it clear messages instantly. This of course would also stop YOU from talking and I'm not sure if you justwant to recieve the no talking on an individual

[hierholzer]

what do you mean by stop the timer I know sc uses gettickcount to set the timer. is that what your talking about?

[Warrior]

Yea, it uses a timer to decide how long to display messages, just either learn to manipulate that timer or spoof the results so you can instantly remove them

[hierholzer]

Well I took the first offset I found that has text on it witch is 658EB0. After that I went into softice and set a breakpoint. my ending breakpoint is 46E60C. with that I went into W32Dasm and went to that location. This is where it shows the gettickcount  . But my problem is this area has about 23 lines of asm in it and I dont know asm well enough to know what line has to do with how many sec a message stays on the screen. here is the code

Im pretty sure thats what im sopost to be changing somthing in there.. also what should I write this hack in I know vb well but ive read that using vb for making a hack is not a good choice. and I dont know enough asm to write it in C++

[Adron]

You're making a hack to prevent you from seeing them talking. If this is what you want to do, how about squelching them? Or does that not work in-game?

[hierholzer]

hmm.. I thought it would prevent them from talking as well

[Adron]

hmm.. I thought it would prevent them from talking as well

Nope, it would prevent you from seeing them talking, very much like squelching them.

[Topaz]

hmm.. I thought it would prevent them from talking as well

To do that, you'd have to find some major exploit or give them a doctored exe 

[DeTaiLs]

You could keep spamming blank messages and use the expliot to make it not show your name then nobody could talk
