Teleport to Enemy & God Mode

There are actually two more features I tried adding (at least as POCs) to my first CSGO cheat, Jerry’s fart stinks–Teleport to Enemy and God Mode.

First approach

I just tried overwriting the values directly at the memory addresses. Unsurprisingly, it failed because of server-side desync.

Second approach

I figured, since functions like EndScene() tun every frame and keep things synced, maybe I could call a similar function every cycle after tweaking it with a trampoline hook.

After some digging, I found CL_Move for teleporting (ty chatgpt) and onTakeDamage for God Mode (ty myself).

CL_Move

CL_Move forces the engine to process all user commands and sync the player state with the server. My idea was:

  1. set my position near the enemy
  2. zero out velocity on the x and y directions
  3. add a slight jump in z to avoid getting stuck, then
  4. call CL_Move (found by pattern scanning) to sync my new location with the server.

Short story short, it didn’t work. I thought maybe the update speed or frequency was off, so I tried tying it to EndScene() to send updates every frame, but that didn’t help much either. Looks like I need to spend more time undrestanding CL_Move and the rendering pipeline, especially tickshifting and whatnot. Or maybe I’ll just look for a better function if this one doesn’t pan out.

OnTakeDamage

OnTakeDamage, you guessed it, is called whenever an entity takes damage. For God Mode in CS:GO (which gives you infinite health–side note: in CS2, they removed God Mode and added Buddha Mode, where your health just won’t drop below 1 HP), I thought looking for a damage-related function would be a good start.

I poked around the source code (static analysis) and set some breakpoints (dynamic analysis) on functions triggered by player damage. Didn’t find much useful from breakpoints, but from the source code. I found OnTakeDamage inside the CBaseEntity and CBasePlayer classes.

As you can see, after several checks in CBasePlayer::OnTakeDamage such as flags for God mode, armor, etc, the actual health reduction happens in CBaseEntity::OnTakeDamage. I thought hooking that function after figuring out its address through pattern scanning would work, but turns out it’s never called when anyone takes damage–not me, not other players. So I still need to find the real function that’s triggered on damage. Too bad this wasn’t the one.

Then I looked at the clock and thought, well, I’ll get back to this later.

(Added) Skin Changer

Found it from another csgo internal hack and thought it sounds interesting…(TMI: Mannnn they have such a better looking UI than mine lol and so much more toggles/options you can modify.)
