 Posted: Sat Dec 28, 2019 2:09 pm Post subject: How to convert values to other numbers |
 |
|
I have a value that needs to be added to and then multiplied to get a different number that I can use.
Just as an example, let's say I have x as the value. I need to add y and then multiply by z to get z(x + y).
I don't want the value to actually change in game, I just need the value to change for the user.
Is there a way to get this to show in the value column of Cheat Engine? I have coding experience in other languages, but none in Lua or Assembly, so please give me additional instructions.
Additionally, is it possible to have this work in the opposite direction? So if I input z(x + y) into the value column, it'll push x back to the game.

Use a custom value type. Right click the value type drop-down list and select "define new custom type" (AA or Lua). AA is better in general.
I can give an example if you give more information. What type of value you're looking at (i.e. integer or floating point), and do y or z ever change?

I found the new custom type menu, what should I type into there?
The value is a 2 byte integer, shouldn't be a float because there's no decimal
y and z never change, they're always the same value I need to add and then multiply by.

This may work (haven't tested it):
| Code: | alloc(ConvertRoutine,1024)
alloc(ConvertBackRoutine,1024)
alloc(TypeName,256)
alloc(ByteSize,4)
alloc(UsesFloat,1)
alloc(CallMethod,1)
// these are in hexadecimal
define(CONST_ADD,C)
define(CONST_MUL,7)
TypeName:
db '2 Byte Add Mul',0
ByteSize:
dd 2
UsesFloat:
db 0
CallMethod:
db 1
// cdecl int ConvertRoutine(unsigned char *input, PTR_UINT address);
ConvertRoutine:
[64-bit]
movsx eax,word ptr[rcx]
[/64-bit]
[32-bit]
mov eax,[esp+4]
movsx eax,word ptr[eax]
[/32-bit]
add eax,CONST_ADD
imul eax,eax,CONST_MUL
ret
// cdecl void ConvertBackRoutine(int i, PTR_UINT address, unsigned char *output);
ConvertBackRoutine:
[64-bit]
mov eax,ecx
mov r9d,CONST_MUL
cdq
idiv r9d
sub eax,CONST_ADD
mov word ptr[r8],ax
[/64-bit]
[32-bit]
mov eax,[esp+4]
mov ecx,CONST_MUL
cdq
idiv ecx
mov ecx,[esp+C]
sub eax,CONST_ADD
mov word ptr[ecx],ax
[/32-bit]
ret

It works, many thanks to you!
I'm guessing you change these lines to see what to add and multiply by?
| Code: | define(CONST_ADD,C)
define(CONST_MUL,7) |

Yes - change the text between the comma "," and closing parenthesis ")" to whatever hexadecimal integer you want.

You can also do it on a per memoryrecord item
e.g:
| Code: |
y=1
z=2
AddressList[0].OnGetDisplayValue=function(mr,currentvalue)
local vi=tonumber(currentvalue)
if vi then
vi=vi+y*z
return true,vi
else
return true,'What the fuck is this value?'
end
end
|
This will set the first memory record to (value+y)*z , assuming it can be read and you can update y and z at runtime.
Just visual though (you could use the addresslist's OnValueChange method to override it)

Sorry, I don't understand where to use this code. Do I right click the value type and make another custom value?
