FearLess Cheat Engine

Hi, i'm trying to get the "Stamina", the "Noise", the "movement speed walk/run" and the "Stealth" but there are no possible way for me to find these stats in memory, i don't want someone to solve it for me, i wish to get a hand to understand what i'm doing wrong. if anyone can help me pls... Thx.

Hi, a question, how do i learn to do these kind of trainers? i'm software developer but i can't find the way to do that, i mean like "highlight the spotted animal", changing values like ammo or money is not a problem. Thx.
