Re: RISE OF THE TOMB RAIDER Health hacking

Post by Daijobu »

I did this last year. I'm completely uncertain if this is any help since I haven't touched the game since the time stamp in the comment up top.

Script 1 (primary):
1. Find player health global (accessed every frame) right from the get go after loading game or whatever
2. Find a static value (pseudo "isPlayer" for example) found somewhere near

Script 2 (sub-script 1):
1: Find writable player health or object health since it iterates over enemies/npc's as wel
2: Use the static reference from Script 1 to do a compare (appears I used negative offset 2D0 which isn't exactly near but it worked)
3: Write player health if (pseudo) "isPlayer"

Good luck.
