If you could give me the Game Name I can provide more detailed information for specific engines and even try to find it for you.
- Most of the games got Player Data inside some sort of structure all at one place. Try to use Cheat Engine to "dissect data / structures" around your health address.
- It might be useful to find the address for the state of sprinting by searching for 1 when true, and 0 when not. Then finding out what accesses that address.
- There might be some information about the game and or code snippets of game cheats / hacks on the web as well. If you can't find a section for it on mpgh try to google for "structs reversal insert-game-name-here".
