how to find array of bytes from an existing adress?

hi! I have a question;
how to find array of bytes from an existing adress?
its a simple question I hope someone can tell me :)

Open search engine and attach it to the game.
Go memory viewer.
Right click the upper part -> Go to adress.
There you have, look at the bytes column.

it's harder than that. You have to know how much of those bytes you need for your specific hack. I've seen really bad scripts where people write down like 40 bytes, and then if the game updates, they can't find it because they have too many. It depends on how long your code is (how many lines in the viewer it takes)
