Cheat Engine

Hi, I'm writing a script to nullify damage against the player but allow damage against enemies. I wrote the script successfully in assembly with the auto assembler but now I would like to try the same cheat using LUA. The issue I have is that when I try to read from or write to R8W it fails. This is what I have at the breakpoint, should be pretty simple so i know I must be missing something:

r8w is just the lower 16 bits of the 64-bit r8 register.

writeSmallInteger takes an address. R8W is a 16-bit value- not an address. If you want to change the register, then modify the variable and CE will change the thread context after the Lua function returns.

Use debug_setBreakpoint callback, not debugger_onBreakpoint. No need to return anything or use debug_continueFromBreakpoint either with the callback.

Aha! Yes, I was just trying to learn about the R8-R15 registers. But I was thinking I would need an offset from R8 to write to R8W.
Also, I appreciate your advice on how to write this more efficiently. Thank you! This really does help me understand the problem and I appreciate your time
