Cheat Engine

[Damaskox]

Good day!

(next to no Cheat Engine usage skills here!)
I've been dreaming a few days so far about a cheat that would otherwise give the normal amount of souls upon an enemy defeat but in addition you'd get one percent extra based on your soul bank that you already have.
So if I had 1000 souls on me already and I'd kill something worth 20 more souls, I'd get 20+10=30 souls in total on top of that 1000.

Is such a thing achievable with Cheat Engine?
Also - would such a cheat work on both vanilla and a modded one (e.g. Convergence)?

Thanks in advance!

Yes, it's achievable, but requests aren't handled on these forums. Try a third party site if you don't want to do this yourself:

Code injection would be the correct way of doing this. You can probably inject at the instruction that increases your souls when you kill an enemy. That's easy enough on its own, but if the instruction accesses more than that one address or is run more often than you'd like (e.g. when your souls decrease), you might need to do something weird like handle the shared code in step 10 of the tutorial or inject at a caller to the function that decreases your souls.

If it's simple, the code might look something like this if souls is a 4-byte value:

Oh! Good to know!

Thanks for the info - and for the code!

"..." is called an ellipsis. It's used as an intentional omission of something else- in this case, code.

I expected you to read that code I posted and try to learn from it so that you can use it in your situation. Specifically, find an injection point, generate a template there, and write code that does what you want.

Try going through the CE tutorial. There are plenty of video guides.
