[Help?] Wow crashes when changing and freezing a value or value changing does nothing

[Alfalfa]

Hey all. I'm having trouble changing my character model's transparency/alpha (how see through you are while zooming in real close) value with cheat engine. I found a float that would make my character flash when I froze it at 0, then I tried again today with 64 bit wow and when I froze it at 0 wow crashed... I searched these forums and I looked in the dumps here but I couldn't find anything related to alpha. I'm not sure what to do, I found a semi working value but it would go back like it wasn't the "real" value. Similar I think to how you can find your zoom and you can find a camera distance value, if you change cam dist to something and scroll, it will change back, but if you change zoom and scroll it doesn't and acts normally.

Anyone have any ideas?

Thanks in advance.

Exact patch, build? Attach olly, follow what happens with the value?

Using live, I believe it's 16992. Will do in a min.

edit: now I found the a similar set of values as the first time, and I found that nothing happens unless I freeze every value (11) at 0...

Ok I'm having trouble finding the actual address. It might not even be one address... I found some that when I freeze it at 0 it would flash across my screen. Kinda at a loss now.

edit again: I found what I think are the right ones, but I changing them does nothing, and there are 8 of them.

Here's some pics.
zoomed far enough back so that alpha (presumably) is 1


zoomed in to about 3/4s alpha


zoomed into my mount so that alpha is about half


zoomed in to max, so alpha would be 0

I think you need to call Unit_UpdateDisplayInfo() after setting one of these values to 0. (The one you need to change would stay at 0 without freezing I presume)

You can actually change any object alpha ingame, the thing is to get this object updated. Though, it's easy to do the thing you want to.
Unit alpha is at [[base+0x978]+0x14] and its Int32. It's also 0-255 (divided then by 255 to bring it into 0-1 range). Just change it and to get your char updated just mount up or dismount. Result:

Btw it was rather interesting for me to find it out, got some sick shit while reversing and mem writing (some canonical unit changed, touched the whole world):

That reminds me of the LSD patch:

Yes, it's nearly the same effect

Thanks for your help everyone

Also, that patch looks cool master674

If I get this to work I could play in first person, with my weapons
