#1: If the value does not change at all, the memory is protected and writing operations are failing. Use VirtualProtectEx() to change the memory protections.
#2: If the value changes but then goes back to the original, it is being written by the game every frame (or more, or less) and you need to constantly change it, not just once.

Are there any other methods other than the VirtualProtectEx()? I always just used ReadProcessMemory & WriteProcessMemory.

VirtualProtectEx() is used to change memory protections to allowing reading/writing of RAM.

ReadProcessMemory() and WriteProcessMemory() read and write RAM.

If you want an alternative to VirtualProtectEx() you have to write a kernel-mode driver.
