first do the tutorial after that open cheat engine in the left corner are three icons click on the most left 1 then you will get the procest list scroll down and click warrock after that go back in warrock whit alt+tab go in to harbor-ida or something (just a small level you need) then if you dont now the value you search unknown intial value after that search is finishd you can do a decreasd or increasd search or float or double etc. but to understand the last 2 you have to finish the tutorial if the value you want to search is decreasd search that sort if its increased search that sort if you found the value you needed klick it double and it will become at the bottom table.
you can change the value by double click on it. or at the debugger for a trainer.
wel i hope it helped you
