here r some sigs in kitterengine

size_t GlobalsSigGmod = FindSignature("client.dll", "A1 ? ? ? ? C1 E6 08 03 B3 ? ? ? ?");
 if (GlobalsSigGmod != 0)
 {
  s_Globals = **(CGlobals***)(GlobalsSigGmod + 1);
  return;
 }

 size_t GlobalsSigBlackmesa = FindSignature("client.dll", "A1 ? ? ? ? F3 0F 10 40 ? 0F 2F 81 ? ? ? ? 72 03");
 if (GlobalsSigBlackmesa != 0)
 {
  s_Globals = **(CGlobals***)(GlobalsSigBlackmesa + 1);
  return;
 }

 size_t GlobalsSigSynergy = FindSignature("client.dll", "A1 ? ? ? ? F3 0F 10 40 ? 0F 2F C1 76 12");
 if (GlobalsSigSynergy != 0)
 {
  s_Globals = **(CGlobals***)(GlobalsSigSynergy + 1);
  return;
 }

 //"gameui_preventescapetoshow\n" above it is call to globals->curtime + 0.25
 size_t GlobalsSigL4D1 = FindSignature("client.dll", "A1 ? ? ? ? 83 78 14 01 74 0C 8B 49 14 85 C9 74 05 E9 ? ? ? ?");
 if (GlobalsSigL4D1 != 0)
 {
  s_Globals = **(CGlobals***)(GlobalsSigL4D1 + 1);
  return;
 }

I personally prefer to use CHLClient->HudUpdate ( https://github.com/VSES/SourceEngine2007/blob/43a5c90a5ada1e69ca044595383be67f40b33c61/se2007/game/client/cdll_client_int.cpp#L903-L925 ) to grab globals.

Code: [Select]

CGlobals = **(CGlobalVarsBase***) (Util::FindPattern((DWORD)GetModuleHandleA("client.dll"), 0x7FFFFFFF, "\x8B\x0D????\xD8\x49\x0C") + 0x02);

The + 2 is an exercise for the reader to figure out, I suppose. ?\_(ツ)_/?
