Cheat Engine

Hello
I am currently messing around with Fallout 4

I watched a tutorial about making an exp multiplier and thought i'd try and replicate it somewhat in Fallout 4.

I've managed to locate my exp and the value responsible for adding in more xp

for example
XP = 23DE1526ED4 - Float = 240
Added XP = 23D8D171D94 - Float = 3.5

Naturally, i figured that by simply finding what writes to the address (or accesses) i might stumble upon the registers which are calculating 3.5, my plan was to add a multiplier in before 3.5 was calculated.

Unfortunately, both the XP and the Added XP locate to the same instruction below:

Fallout4.exe+E25BE5 - F3 0F11 70 04 - movss [rax+04],xmm6

I've tried looking around the memory region this code is located in but haven't managed to find anything that i figured was useful. I am quite new to cheat engine and have been trying to figure out break and tracing with no avail.
In the break and trace, the xmm6 value is not 3.5/240, but a very large float (90000 or something like this). rax+04 is neither 3.5/240, but a very large number that looks like an address.

Currently, i think that maybe this task is too advanced for me so i thought i should ask the veterans here for advice.

That instruction is likely accessing many addresses. You'd need to set a start condition on the break and trace- e.g. RAX+4 == 0x23DE1526ED4

From there, you could look up the callstack (step over w/ lower tracecount might help) and scroll up see what happened leading up to that point. That would require knowledge, experience, and time that most people don't really have, however. If anything weird is happening- e.g. the game is interpreting code from some script- you're going to be in for a bad time.

Learning how to mod the game might be easier.

This is extremely helpful advice, thank you very much for your time!
