This tutorial is very old but it is still useful to this day. In this case, I will be using GameGuardian and hack the cooldown bar in Blitz Brigade. This is easiest way to find unknown values
Pause the game, Open the memory editor, and select an app you want to hack
Do fuzzy searching
If it ask you to select the type, just click YES, if you don't know what type of the bar it is using
Minimize the memory editor
Resume the game, and increase the bar
Pause the game, open the memory editor, click FUZZY
Select "Larger"
Keep repeating until the bar is near full like this
Now decrease the bar. Pause the game, open the memory editor, click FUZZY and Select "Smaller" instead "Larger"
Repeat until the bar is empty
Keep repeating from the beginning until you get few results left.
Now I have 6 results left. This is how the encrypted value looks like when there is the values in the bar
This is how the encrypted value looks like when the bar is empty
So you have to try change one by one to see which one is right. The last one is the right one
Change and freeze the value
That's it. Enjoy
