Using Cheat Engine to make an ESP/Wallhack

Hello everybody, I'm new here!!

I've been a Cheat Engine user for seven years, but in these seven years I have not really been learning much, just basic memory scanning/pointers with absolutely no knowledge of CE Scripting (I've completed the tutorial up to the last step).

I'm fascinated by the concept of using Cheat Engine to read enemy X-Y-Z coordinates in a First Person Shooter game, to know where they are, and also, paint them on the map, to see them through the walls.

I already have thoroughly completed the first part, I got the enemy coordinate addresses in the game, they are readable and static. However, I am wondering where to go from here. I've never been closer to doing something like this, and I've been interested in doing this for a while. Does anybody have any tips on what to do? I knew how to code using C++ four years ago, but alas, I do not know what to do now. There was a tutorial here somewhere on mpgh that showed the trig behind it, and used C++ but that's not what I want to do, I don't want to make an aimbot just yet, I want to paint the coordinates, either on the map or on the screen. Is there a detailed guide anywhere??

The game I am using is really easy so it will be good for practice. I am avoiding naming it because of copyright issues (On CEF they told us to do that)
