Do Red Boxes have offsets?

[evildr]

Bit of a long shot, but anyway...

Having played the game to death the normal way, I've been programming a hack to switch on certain features using a VB.Net Timer, which is working okay.

I'm trying to improve it however by enabling the red boxes that appear when you use a Remote Sentry, or AC-130. Is it possible to enable those red boxes while you're in first-person player (e.g. normal) mode? I've tried a memory search and get about 40 results, but when I try to find "what accesses these addresses" in CheatEngine, it crashes iw5mp.exe.

Can it be done, and if I ask really nicely, can anyone supply the red box offsets? Thank you!

All the methods so far have been hooking the game and calling the function in the frame. ( Traditional chopper boxes that is )
I'm sure, just like all other CoDs since CoD1, you can do it with a simple memory patch but you'll:

1.) Be editing the .text section which is bad for VAC
2.) Have to find it yourself because it's not public

Look at this post https://www.mpgh.net/forum/showthread.php?t=402537
Its a way on how to call these boxes, you have to hook a renderthread and call the function from there. Another method would be patching the instruction that checks if you are in a chopper to make it visible at all time

Thanks cardoow, much appreciated. I tried the second suggestion, but with the Timer object the screen just went nuts and flickered between 1st/3rd person which was impossible to play with. Is the post you suggested a C++ example? I'm new to hacking but have strong(ish) VB.Net skills. Just wondered where I might be able to get some more info about applying it rather than asking for it delivering on a silver platter...?
Cheers.

Cheers for that. Thought it might be risky!
As for number 2, that's what I was trying for but the bloody game crashes out EVERY time!

MW3 for VAC has anti-debugger techniques. Use some weird plugin for Ollydbg and it'll work out fine.
If not, download TeknoMW3/PlusMW3.
It's safer to try hacking there. Any offsets you get there can be found on steam with a simple pattern search.
