Cheat Engine [Questions]

Yes i am new to making hacks and so far the only thing i know how to do with cheat engine is -
Find some simple addressess ( i dont think ill find anything else lol )
Only thing i can find addresses on is DragonFable
I finally learned how to make the addresses into a trainer
and thats pretty much it

and i wanna learn how to do the stuff below -if any1 can teach me

How can i make a bypass ??
How do you find addresses like super jump and weapon ( like winchester )
How do u get cheat engine to be undetectable??(cuz i got banned for trying it on warrock)
ive been hearing a lot about UCE and i dunno where to get one
For Value type and Scan Type how do u know which ones to use to find the correct address? or can u use which ever and will it give u the same results??

i made a simple DragonFable trainer with NaN DMG and thats all i felt like doing i was just testing if it worked (im not sure i put the right freeze value in it i havnt played it in long time)
EDIT> couldnt add attachment (not right file) so ya but it works so if any1 could teach me the stuff i need?
