 Posted: Tue Aug 19, 2014 8:45 am Post subject: Using lua variables in autoassemble |
 |
|
I'm totally new to lua and assembler and I didn't find any solution in the internet.
I want to print an item list into the lua output, but I'm having trouble using variables right.
For example this function which shall print pointers to items with the ID of 0 to 16 (I know the print is not in the loop, but atm I'd just like to know how to use those variables right).
| Code: | itemid = 0 //item ID
item = 0 //a pointer to the item data
autoAssemble([[
alloc(mem,128)
label(.Break)
label(.While)
CreateThread(mem)
mem:
//mov itemid, 0
.While:
cmp itemid, 0x10
jae .Break
mov edx, 1 //count
mov eax, itemid //Item ID
push edx
push eax
mov ecx, [GameInternAddress] //Player
call GameInternFunction
mov pointer, eax
inc itemid
.Break:
ret
dealloc(mem)
]])
print(pointer) |

In the autoassembler,numbers are in hex by default,no need to write 0x10,write one of the following: 10 , (int)16 , #16 .
2- Labels don't start with a dot,the dot is used in structure members and library functions,like Kernel32.lstrcmpiA .
3- Wait a bit before using dealloc,here is what I'd write:
| Code: |
itemid = 0 //item ID
item = 0 //a pointer to the item data
autoAssemble([[
alloc(mem,128)
alloc(itemid,16)// Should be enough
alloc(pointer,16)
registersymbol(pointer)
registersymbol(itemid)
label(Break)
label(While)
CreateThread(mem)
{$lua}
writeInteger('itemid',itemid)
{$asm}
mem:
//mov itemid, 0
While:
cmp [itemid], 0x10
jae Break
mov edx, 1 //count
mov eax, [itemid] //Item ID
push edx // Is this one of the function arguments?
push eax // Is this one of the function arguments?
mov ecx, [GameInternAddress] //Player
call GameInternFunction
mov [pointer], eax
inc itemid
jmp while // return to the top
Break:
ret
{$lua}
sleep(3000) -- Should be enough
{$asm}
dealloc(mem)
unregistersymbol(itemid)
dealloc(itemid)
]])
print(('%08x'):format(readInteger'pointer')) |

Thanks, your code helped me a lot already. 
But I still don't know how to connect the lua variables with assembler variables. For example, if I want to print the output:
| Code: | alloc(id,4)
registersymbol(id)
...
mov [id], 10
{$lua}
print(id)
{$asm}
... |
$lua and $asm seem to have different variables.
in $lua, "id" is nil and in $asm it's 10

id is a pointer to the variable,so it's just an address that points to your value,you used registersymbol in order to access it from Lua:
| Code: | alloc(id,4)
registersymbol(id)
...
mov [id], 10
{$lua}
print(readInteger'id') -- Read a 4-bytes value stored at the symbol 'id'.
-- You can find all the functions in main.lua
{$asm}

But if I use this code:
| Code: | alloc(main,256) //main thread
alloc(id,4) //item id
registerSymbol(id)
label(Loop)
label(Break)
createThread(main)
main:
mov [id], 0
Loop:
cmp [id], A
jae Break
{$lua}
print(readInteger'id')
{$asm}
inc [id]
jmp Loop
Break:
ret
//Exit:
{$lua}
sleep(1000)
{$asm}
unregistersymbol(id)
dealloc(id)
dealloc(main) |
I just get "10" printed in the output, even BEFORE the code is injected, instead of 0,1,2,...,10 o.O
Also, if I assign my script to the cheat table and enable/disable it from there, I get no output at all.

The lua sections are 'preprocessors" their result is what gets assembled into aa code.
If you wish to call lua functions from inside the target process check the lua template in the aa. (Using the luapipe)
Anyhow, i recommend just doing what you need in assembler

Any idea how to get an easy output then?
