Help me to Hook 64bit Void method offset please

[moh4mmed]

I tried using Hacker House method patching library (it does work on 32bit but not on 64bit) if someone can help them please do help

Here is my 64bit method offset (it doesn't need update offset in 32bit to get working)

// RVA: 0x2B63640 VA: 0x2B63640

 internal void set_damageMultiply (float set_damageMultiply) { }

Find R1 from a couple of first instruction inside the method/function. Then you can use immediate float:

example: mov r8, r1
change to: VMOV.F32 s0,#2.00000000 & VMOV R8, S0 --float 2

---
If you need more precision float, the instruction might be long, that's why you can allocate memory -> mimic the same instruction on allocated memory -> add the modified instruction -> jump into allocated memory from inside original method/function.
