Hey,

Today I wanted to start learning some AA, and stuff that associates with it.
So, I took the CE tutorial, and got up to the bit with multiple pointers. I couldn't be bothered learning them, and I thought I could experiment with what I had learned. So, I opened up Minesweeper, targetted it, and then found the addresses for the Flag count and the timer. Easy.

Then I tried injecting something to each.
The Flag count:
Code:
alloc(newmem,2048) //2kb should be enough
label(returnhere)
label(originalcode)
label(exit)

0100346E:
jmp newmem
nop
returnhere:

newmem: //this is allocated memory, you have read,write,execute access
add [01005194],10


originalcode:
//add [01005194],eax

exit:
jmp returnhere


Which adds 10 to the flag count every time you use one, so you have infinite, really.

The Timer:
Code:
alloc(newmem,2048) //2kb should be enough
label(returnhere)
label(originalcode)
label(exit)

01002FF5:
jmp newmem
nop
returnhere:

newmem: //this is allocated memory, you have read,write,execute access
dec [0100579c]


originalcode:
//inc [0100579c]

exit:
jmp returnhere


Which would decrease the timer instead of adding to it.

So to check on something, I needed to make the original code a comment so the new code I inputted would actualy work? Or doesnt the originalcode work when you inject something?

1 last thing:
I've been reading samuri25404's AA tutorial and ive come down to 'Label'.
Here's his code:
Code:
label(AutoAssembler)
label(Continue)
label(SayWhat)

AutoAssembler:
mov eax,02
cmp eax,03
jne Continue
je SayWhat

His explination of it was:
Quote:
What it does is allows the variable that you "label" to be used in your script


So, it labels a variable for you. But he hasn't specified what variable or anything, just named something that doesn't exist to 'AutoAssembler' or 'Continue' and 'Saywhat'.

Am I missing something?

Any help is greatly appreciated.

samuri25404's script you posted here is incomplete and will not function properly (even though it might execute)

here's how the AA algorithm does it:

Code:

alloc(newmem,2048) //2kb should be enough

Create a variable newmem that gets a specific address

Code:

label(returnhere)
label(originalcode)
label(exit)

Tell the autoassembler to expect a variable definition named returnhere, originalcode and exit

Code:

01002FF5:

Set the current code write pointer to address 01002ff5

Code:

jmp newmem
nop

Assemble this code at address 01002ff5 and further and increase the current write pointer

Code:

returnhere:

Variable definition, returnhere gets the value of the current write pointer

Code:

newmem: //this is allocated memory, you have read,write,execute access

Not a label but a alloc, meaning, change the current write pointer to the allocated memory

Code:

dec [0100579c]

Write at the current write pointer this code and increase the write pointer with this size

Code:

originalcode:

Variable definition, originalcode gets here the address of the current write pointer

Code:

//inc [0100579c]

Ignored

Code:

exit:

Variable definition, exit gets here the address of the current write pointer

Code:

jmp returnhere

jmp to the address returnhere gotassemble this instruction at the current write pointer. Set returnhere to the address it got from the variable definition

Thanks for that.

It's a real help knowing how it goes through and does things, and you've explained it in a very informative way, however, i'm going to have to look up 'nop' and learn some more about it.

Thanks again!

-I've got my minesweeper scripts working now!
Backwards Timer:
Code:

[enable]
//Script by Montycarlo! :D
alloc(newmem,2048) //2kb should be enough
label(returnhere)
label(originalcode)
label(exit)

01002FF5:
jmp newmem
nop
returnhere:

newmem: //this is allocated memory, you have read,write,execute access
//place your code here


originalcode:
dec [0100579c]

exit:
jmp returnhere


[disable]
dealloc(newmem)
01002FF5:
inc [0100579c]

Infinite Flags:
Code:

[enable]
//Script by Montycarlo! :D
alloc(newmem,2048) //2kb should be enough
label(returnhere)
label(originalcode)
label(exit)

0100346E:
jmp newmem
nop
returnhere:

newmem: //this is allocated memory, you have read,write,execute access
add eax,A


originalcode:
add [01005194],eax

exit:
jmp returnhere
[Disable]
dealloc(newmem)
0100346E:
add [01005194],eax


I played around with the injection, looked at some scripts from other people and eventruly compiled my own. Have I got any errors in my script?

Thanks again!

oh yeah, flags isn't really important for minefield, because it doesn't count

Doesnt matter he is learning how to use the AA scripting. Pay attention, and read the topic.

@DarkByte:

Yes, thanks for telling him that. I know that it's wrong, and I've known for a while; I wrote it when I didn't know as much as I know now, and at the moment I'm just too lazy to fix it.

Eventually (and probably soon, if boredom consumes me), I'll go back and fix it.
