Hello everybody!

Here, I have a question! For a script.

I know in the script assembler on cheat engine.
That functions:
Add: Used to add.
Inc : Used to decrease.

But I would like to know how one says equal in function assembler.

Code:

add [esi],0 // To add
sub [esi],0 // To subtract
mov [esi],0 // To assign
inc [esi] // To increase by 1
dec [esi] // To decrease by 1

These are some of the basic commands.

Can't post links:

Mod Edit: Links fixed and clickable.

Typically, a conditional jump following some kind of compare:

Code:
cmp [eax+04],64      //compare the value of [eax+04] to 100
je 001204E5          //if equal, jump...
mov [eax+04],64      //...else set the value of [eax+04] to 100


Not sure if that answers your question, though.

With your two answers, I do not know how to make it always equal.

What I want to do is equally come function.
Example:
Code:

add [esi],0 // To add

add [esi], =100 //Always stay on 100


But I can not do it in the script.
So I think to do such a function
I would have to:
Code:

mov [esi],0 // To assign
mov [eax+04],64
 
mov [esi],100 //This value of this function says to stay at 100
cmp [esi],-100,100,+100 //These values of the function do not stay even if the values are 99, 101, -10..

That would be the kind of thing I'd like to do in this script.
I know that the signs are not taken into account, it is just to make understand what I would like to do more easily.

-Just use mov:

Code:
mov [esi],100


This will set the value to 100, always, unless some other instruction is also writing to that address -- then you would need to do the same for that other instruction.

Thank you so much! I was looking for this for a while, it will help me a lot to do what I want. Thank you so much.

Yes, what makes sense if one instruction and the same! Normal.

Thanks to you both in any case, it also allows me to have more knowledge in this language

By the way:

Code:
mov [esi],100


Will set the value to 100 (hexadecimal), or 256 (decimal). If you want to set the value to 100 (decimal), then you can write it like this:

Code:
mov [esi],#100


or...

Code:
mov [esi],(int)100

It's probably with what you told me, I'll see her. Even if I would like to have health at 1000 directly. When I just click and the rest ..
