Step 4: Floating points (PW=890124)

In the previous tutorial we used bytes to scan, but some games store information in so called 'floating point' notations. 

(probably to prevent simple memory scanners from finding it the easy way)

a floating point is a value with some digits behind the point. (like 5.12 or 11321.1)

Below you see your health and ammo. Both are stored as Floating point notations, but health is stored as a float and ammo is stored as a double.

Click on hit me to lose some health, and on shoot to decrease your ammo with 0.5

You have to set BOTH values to 5000 or higher to proceed.

Exact value scan will work fine here, but you may want to experiment with other types too.

Step 3: Unknown initial value (PW=419482)

Ok, seeing that you've figured out how to find a value using exact value let's move on to the next step.

First things first though. Since you are doing a new scan, you have to click on New Scan first, to start a new scan. (You may think this is straighforward, but you'd be surprised how many people get stuck on that step) I won't be explaining this step again, so keep this in mind

Now that you've started a new scan, let's continue

In the previous test we knew the initial value so we could do a exact value, but now we have a status bar where we don't know the starting value.

We only know that the value is between 0 and 500. And each time you click 'hit me' you lose some health. The amount you lose each time is shown above the status bar.

Again there are several different ways to find the value. (like doing a decreased value by... scan), but I'll only explain the easiest. "Unknown initial value", and decreased value.

Because you don't know the value it is right now, a exact value wont do any good, so choose as scantype 'Unknown initial value', again, the value type is 4-bytes. (most windows apps use 4-bytes)click first scan and wait till it's done.

When it is done click 'hit me'. You'll lose some of your health. (the amount you lost shows for a few seconds and then disappears, but you don't need that)

Now go to Cheat Engine, and choose 'Decreased Value' and click 'Next Scan'

When that scan is done, click hit me again, and repeat the above till you only find a few. 

We know the value is between 0 and 500, so pick the one that is most likely the address we need, and add it to the list.

Now change the health to 5000, to proceed to the next step.

Step 2: Exact Value scanning (PW=090453)

Now that you have opened the tutorial with Cheat Engine let's get on with the next step.

You can see at the bottom of this window is the text Health: xxx

Each time you click 'Hit me'  your health gets decreased.

To get to the next step you have to find this value and change it to 1000

To find the value there are different ways, but I'll tell you about the easiest, 'Exact Value':

First make sure value type is set to at least 2-bytes or 4-bytes. 1-byte will also work, but you'll run into an easy to fix problem when you've found the address and want to change it. The 8-byte may perhaps works if the bytes after the address are 0, but I wouldn't take the bet.

Single, double, and the other scans just don't work, because they store the value in a different way.

When the value type is set correctly, make sure the scantype is set to 'Exact Value'

Then fill in the number your health is in the value box. And click 'First Scan'

After a while (if you have a extremely slow pc) the scan is done and the results are shown in the list on the left

If you find more than 1 address and you don't know for sure which address it is, click 'Hit me', fill in the new health value into the value box, and click 'Next Scan'

repeat this until you're sure you've found it. (that includes that there's only 1 address in the list.....)

Now double click the address in the list on the left. This makes the address pop-up in the list at the bottom, showing you the current value.

Double click the value, (or select it and press enter), and change the value to 1000.

If everything went ok the next button should become enabled, and you're ready for the next step.

Note:

If you did anything wrong while scanning, click "New Scan" and repeat the scanning again.

Also, try playing around with the value and click 'hit me'

Welcome to the Cheat Engine Tutorial (v3.3)

This tutorial will teach you the basics of cheating in video games. It will also show you foundational aspects of using Cheat Engine (or CE for short). Follow the steps below to get started.

1: Open Cheat Engine if it currently isn't running.

2: Click on the "Open Process" icon (it's the top-left icon with the computer on it, below "File".).

3: With the Process List window now open, look for this tutorial's process in the list. It will look something like "00001F98-Tutorial-x86_64.exe" or "0000047C-Tutorial-i386.exe". (The first 8 numbers/letters will probably be different.)

4: Once you've found the process, click on it to select it, then click the "Open" button. (Don't worry about all the other buttons right now. You can learn about them later if you're interested.)

Congratulations! If you did everything correctly, the process window should be gone with Cheat Engine now attached to the tutorial (you will see the process name towards the top-center of CE).

Click the "Next" button below to continue, or fill in the password and click the "OK" button to proceed to that step.)
