accuracy memory address

I found a solution like cheatengine but I have no idea how to find the memory address to edit ..... can anyone help?
for now I was able to use only the rail unlimited shots.....

Thanks in advance!!

does not ... EAC is present since the major update ... I think this change can only be made via ... '' Assembly-CSharp ''

So why i'am able to read all the memory of the process?
i repeat, unlimited rail ammo works.....
