How soon will be update for Ohack?
And I cant open source, what version of studio need for it? 10 cannot open this.

[advanta]

edit that, cant get this to work to save my life

Me neither, it won't inject the module.

Thanks to the author for such a great program btw.

Are the GUI commands protected LUA functions? I recognized it wouldn't draw without unprotecting the LUA function.

The functions used for drawing the UI shouldn't be protected, since addons use them also. Thanks for updating some of the offsets for me. It saved me some time updating it. +3 Rep.

OHack is updated for 5.0.5 (16048). The only thing that isn't updated is the tracking hack (it's crashing, not sure why yet, needs more work).

I just finished updating the offsets myself, there is one that I'm not so sure about though, maybe its a mistake or maybe its just a name difference. Check out CGUnit_C__GetUnitName, and my comment next to it.

OHack is updated for 5.0.5 (1604. The only thing that isn't updated is the tracking hack (it's crashing, not sure why yet, needs more work).

Your welcome Thank you for this great project!
Could you update the source package please? The linked source is still for 5.0.4.

The source is updated now. I forgot about it.

[eracer]

The source is updated now. I forgot about it.

I went through and made sure everything was the same just to confirm and only the offsets i had questioned were not right and I had the right ones in the comment.

I had to make a few changes to the OLoader to get it to run correctly on my system, the main thing was that in Process.cpp the line that reads "ProcessList->SetSelectedItem(0);" was throwing an unhandled exception error when i run it and there is no wow process open, since its trying to set a selected item when there is no items. I just wrapped that in a try catch and it fixed that problem.

Thanks for the awesome open source hack, I would rep you but it says I must spread some around first.

[Vaudville]

There was another update tonight, 5.0.5.16057.

Not a major change I don't think, but check anyway please?

[Sikas]

The offsets weren't changed, you can still use this hack. Though what they changed client side, I have no idea. It's unusual that they'd not change any offsets client side.

[Jimo8]

.scale command not work for me. imgur: the simple image sharer

Running windows 7 64 bit,and 32 bit wow

[daCoder]

Thanks for the source. It looks like you only changed the offsets file and the entry. It is compiling with an error, cause you haven't commented out the tracking code.
And it crashes if you want to use the climb hack for example.

Did you forget to update the files in the zip file, which i assume because of the compile error.
Or didn't you patch the addresses in the functions itself?

Movement.cpp
Memory::Write<byte>(WoWBase + 0x4EB0DB, 0xEB);
Memory::Write<byte>(WoWBase + 0x4EB0DB, 0x73);

The original Byte there is 0x10.

If you have done the work, can you reupload the whole package please

[Shirayuki101]

OHack is amazing, updates are fast, and I love it but I've noticed some problems. 1: Scale hack for 5.05 is not working. It says I scale from 1 to let's say, 3, but doesn't actually scale me. 2: This might just be broken or something, but the load map thing always crash when I use it, even to go to SW, so I don't know. Thanks, please try to fix it.

[Shirayuki101]

Oops, one more thing, what happened to talk to all? lol

I reuploaded all of the files. It should work now. Also, I didn't patch the addresses, I patched the jump instructions.

I'll see about fixing these soon.

Blizzard fixed it so it's no longer possible. Before 5.0.4, the client handled languages and this made the language hack possible. In 5.0.4, because people were abusing the language hack (I saw a lot of posts about it on Blizzard's WoW forum, several mentioning OHack), so they fixed it. Languages are handled by the server now, so it's no longer possible.
