If you play Fiesta, you know there's not many public hacks released yet [accept for a bot created by "Labyrnth" which is FANTASTIC I might add!] This is a simple tutorial on how to walk on absolutely nothing as if you were flying.
Step 1: Open your Fiesta Client and begin playing. Open Cheat Engine.
Step 2: Enable "Pause the game while scanning" then have your player stand completely still and start your scan with 0.
Step 3: After the scan is complete, put the integer "1" in the "Value" textbox. Go to the game client then jump. While you are still in the air scan 1 next.
Step 4: After that scan is finished, stand still again and search 0. [Repeat this process until you have about 5-7 addresses left.
Step 5: You will notice two of the found addresses will both go to 1 when you jump, then back to 0 when you are still. But one of those addresses will change to 3 while you are falling. Now take the address which changes from 0 to 1 and freeze it at 1. Now take the other address which changes from 0 to 1 then to 3, and freeze that address at 0.
Resulting outcome: You're figure mesh will be slightly off the ground, now walk off a hill or a set of stairs and you will fly above everyone!
