October 27, Table of Contents. If you're attempting to use Cheat Engine for a browser game, you'll select your browser's name instead. If your game doesn't appear in the "Processes" list, you cannot edit it in Cheat Engine. You may first have to click the Processes tab at the top of the window.
Click OK. It's at the bottom of the window. This will open the game in Cheat Engine. Search for the on-screen number. Type the number that's attached to your preferred aspect into the "Value" text box near the top of the Cheat Engine window, then click First Scan. For example, if the on-screen item you're trying to hack has a value of 20, you would type 20 into the "Value" text box. Change the game's on-screen number. How you do this will depend on the game itself; for example, if you're trying to give yourself more health, you might purposefully damage your own health in order to lower the number.
The end result must be that the on-screen number is different than the number before. Minimize the game again, then search for the updated number. Type the new number into the "Value" section, then click Next Scan. This will narrow down the number of values on the left side of the window. Repeat the search process until you have 4 or fewer values. You'll keep changing the number and then searching for the updated number until you have no more than 4 values listed on the left side of Cheat Engine.
You should eventually see the previous number you searched for listed in the "Previous" column of each value's number, while the current value of the item will be in the "Value" column.
Select the values. You should see all of the values highlighted. Add the values to the address list. Click the red, diagonal arrow in the bottom-right corner of the list of values. Doing so will place the values in the list of addresses at the bottom of the window. Select all of the values. This will open a pop-up window with a text box in it. You may instead need to double-click a value to open this field. Enter the value you want to use. If that is the case, look for the instruction that has a different set of characters between the "[' and "]" brackets than the rest.
If there isn't a single address that has different characters, check to see if the pointer is the same for all of them. That is an offset number. Write it down. You'll need it later.
Click More information. This displays instructions that happen when the value changes in the Extra Info screen. This also lists the pointer that writes to the address. You can also find the address by checking the characters in the bracket, and then checking what number comes after those characters listed at the bottom. Click the checkbox next to "Hex" and do a new scan for the pointer address. The address of the pointer is listed in the text that says "The value of the pointer needed to find this address is probably xxxxxxxxx".
Use the following steps to search for the address at the end of this sentence. Click the checkbox that says "Hex" next to the "Value" field. Enter the pointer address in the Value field and click First scan. Double-click the pointer address. This adds the address to the list at the bottom of Cheat Engine. If the address is listed in green in the scan results. This means it is a static address and probably the pointer you are looking for. In some cases, the pointer you find may also be a pointer.
This is called a multilevel pointer. In this case, you'll need to repeat these steps for each pointer you find in order to find out what the root static pointer address is.
Double-click the number below "Address". This opens the "Change address" dialogue box. Copy the address in the field and click Cancel. To copy the address, simply highlight the entire text in the field at the top of the "Change address" box.
Right-click it and click Copy. Then click Cancel to close the field. Click Add address manually. It's the button on the left above the address list at the bottom of Cheat Engine. This opens a box that looks similar to the "Change address" box, except this one allows you to add an address. Click the checkbox next to "Pointers". This expands the box and adds a new text field where you can enter a pointer. Paste the pointer address in the field below "Pointers" and click Ok.
This adds a new address for the pointer that controls the value that you want to change. This indicates that this is a pointer pointing to a specific address. If there is an offset number, enter it in the space above the field where you paste the address. If there is more than one pointer, click Add offset. This will add more offset number boxes above the area where you paste the address.
Enter the correct offset number in each box. Click the "Active" boxe next to the pointer address you just added. It's the box below "Active" in the list address list at the bottom of the screen. This activates pointer. Change the value of the address you just added. The value number for the pointer address you just created should be the same as the address of the value you searched for. If the pointer writes to a different location, the original address you scanned for will no longer be valid.
However, you can still change the value of the pointer address you just created. That will work no matter where it writes the value location to.
Click the number below "value" for the address you just added. Enter a new numeric value and click Ok. Part 6. This part teaches you how to use Code Injections to change how the code writes a value. For example, if you lose health every time you get hit, you can change the code so that it increases your health when you get hit. This will cause the code that accesses the address you selected to appear in the debugger window. If that is the case, look for an instruction that has the word "sub" in the instruction to subtract from the value, or the word "add" or "inc" to increase the value.
Click Show disassembler. This opens the code in the disassembler. Select the code that subtracts or increases the value. It is usually the first instruction at the top of the code. It will have wlll most likely have the word "Sub" or "Add" at the start of the code to subtract from the value or add to it.
Click Tools followed by Auto Assemble. This opens the auto assembler. Click Template followed by Full Injection. This displays a pop-up window that confirms the address you want to inject code into.
Ensure the address is correct and click Ok. Ensure the address in the field is the same address you selected in the Memory Viewer disassembler window. Then click Ok. This opens a new template. Replace the code with it's opposite. Scroll down to where it says "Code". The line below it is the code that changes the value. If the line starts with "sub", change "sub" to "add".
If the line starts with "add", change it to "sub". You can also change the value at the end of the line to change how much you want it to change the value by. Click Execute followed by Yes twice. The "Execute" button is at the bottom of the Code Injection window.
You will be asked if you are sure you want to inject the code. Click Yes to confirm. Then you can click Yes or No to open the new code in the disassembler. If the code injection was successful, values in your game will do the opposite of what they are supposed to do. You can gain ammo by firing your weapon instead of losing ammo. You can gain health when you get hit instead of losing health. Part 7. In some games, multiple objects share the same code. Injecting code into one object will affect all the others too.
So you might freeze your own health bar, only to realize that the health of all enemies is also frozen. In this case, you need to find out how to distinguish between different objects and inject a script that only affects the object you want. In order to inject scripts for different objects, you need to know some assembly code.
However, it's not too hard to create a basic script. Once you've determined the address of the values you want to change or stop, find out what writes to those addresses, open up the debugger and find out what writes to that address. Select the instruction and click Show disassembler. It's the instruction that is highlighted when you open the debugger. This displays the instructions in the code disassembler.
Right-click the top instruction and click Find out what addresses this instruction accesses. This opens a window that displays a list of all the addresses the instruction accesses when it writes to a new address. Allow all the objects in the game to change their value. This will show a list of all addresses that the instruction accesses. For example, if you are trying to stop your health bar from changing, you can return to your game and get hit.
This will display the instruction that accesses that address in the list of accessed addresses window. If you hit an enemy that also shares that instruction, it will also show in the list of accessed addresses window. Select all addresses in the list of accessed addresses window.
Once you have an address for all objects that share the same address in the list of accessed addresses, simply click and drag to highlight all of them. Alternatively, you can right-click each individual address and click Show register states.
Disect the data of structure of all the listed addresses. Use the following steps to disect the data structure for the list of addresses: Right-click the selected addresses. Click Open disect data with selected addresses. Enter a name for the data structure and click Ok. Enter a starting size of the struct or leave it as is, and click Ok. Find a value that is the same for the player s , but different for other objects.
Whether you are looking at the data structure or the register for each object, you need to find a value that is the same for all allies, but different for the enemies.
For example, if Team 1 has two player characters, and Team 2 has two computer-controlled characters, the Team 1 characters may be represented with a value of 1, and Team 2 might have a value of 2. If can't find a value that is the same for allies, but different for enemies, you can make one. Simply right-click one of the values such as a pointer , and click Add Element. Select "4 Bytes" as the data type and give it an offset number value that is not taken.
Offset numbers are listed to the left in the data dissection structure table. Note the register for the value. Whether you are looking at the register view or data dissection view, the register value is on the left. In the register view, it will be the actual register the instruction writes to i. If you are looking at a data structure, the register will be an offset number or letter listed to the left. Open a new code injection template for the instruction. Return to the Memory Viewer window and open a new code injection template for the instruction that writes to the different addresses.
Use the following steps to do so: Click the instruction in the Memory Viewer window. Click Tools in the menu bar at the top. Click Auto Assembler. Click Template in the menu bar at the top. Click Code Injection. Create a new label for the object you want to affect.
Labels are listed at the top of the code injection template. Add a new label for the object you want to affect below the existing labels. To add a label, simply type label followed by the name of the label in parenthesis. For example, "label player " or "label enemy ". Create a new section for the label you just created.
To create a new section for the label, type the name of the label followed by a colon : anywhere before or after the original code. Add code to the label that changes the value of the object you want to effect. This requires a bit of knowledge of assembly code. You'll need to add a line of code that changes the value for the object you want to change in the way you want to change it.
Then you'll need to add a line that jumps to the exit, original code, return code. Create a comparison code below "newmem". The line that says "newmem:" in the code injection template indicates that the instruction is calling a new memory address.
