With Cheat Engine, when you find an adress in the left of the GUI, you have two differents colors.
- Green : means that the adress is static. If you close the client, it will be the same type of value (X;Y for example) in it
- Black : dynamic adress, if you restart the client, the adress must have changed and can be anything else.
You have to use pointers and offsets to find the static adress of a dynamic one. You will be able the find in ElitPvPers a good tutorial which explains how tu find pointer and multi-level pointer.
Good luck!
