Can someone tell me what a trainer is

[OldCheatEngineUser]

basically a trainer is:
a tool that helps to cheat in games.

about how to make trainers:
you can make a trainer if you have experience in programming languages such as C/C++ or many other PL's.

or you can simply generate a trainer using cheat engine built-in function, that will allow you and help you to make one without putting you hands into coding.

A trainer is a 3rd party application that can edit game values, or edit the way things act in games.

However to make a trainer can be a complicated subject. It will help if you have a coding background such as cpp,c,etc. You can design a custom trainer with cheat engine by clicking on "Table" In the top right corner, and then click on "Create Form" Here is where you can design your trainer. Now just learn how to code in what you want and you'll have a trainer.
