Advanced Cheat Engine uses [need help]

well, im a complete newb at hacking. the best i can do is change scores, health (numbers such as 100%), and ammo for guns. I want to go to the next level, and learn how to hack health bars, jump height, and speed.
I doubt ill get many answers from here, but anything will do.

You can usually find the more advanced values on forums like this, and always remember, google is your friend

to change your speed on cheat engine hit the speedhack button and change it to 3 -.-
