Hello, Im a noob coder, met a problem with my first asm script...
I can't active it, and have no idea about wats wrong.  (( Can anyone help me out with it? Thanks a lot.
Description:
the code is for monster hunter world, used to inject item into the item box.
code:
| Code: |
{ Game : MonsterHunterWorld.exe
Version:
Date : 2018-08-25
Author : EternalSword
This script does blah blah blah
}
[ENABLE]
aobscanmodule(BoxBase,"MonsterHunterWorld.exe",75 00 00 00 01 00 00 00 FF FF FF FF) // should be unique
registersymbol(BoxBase)
alloc(ItemID,4)
registersymbol(ItemID)
alloc(quantity,4)
registersymbol(quantity)
alloc(itcode,$1000)
label(toend)
label(repeat)
label(injectitem)
jmp toend
itcode:
push rax
push rbx
push rbp
push rcx
mov rax,BoxBase
add rax,04A8
mov rbx,rax //@Tip 1
mov rcx,149
repeat:
mov rax,[rbx]
cmp rax,0
je injectitem
add rbx,10 //@tip2
loop repeat
{$lua}
print('fuuuuuuuuull Box XDDD')
{$asm}
injectitem:
mov rax,[ItemID]
mov [rbx],rax
mov rax,[quantity]
mov [rbx+04],rax
pop rcx
pop rbp
pop rbx
pop rax
toend:
[DISABLE]
dealloc(ItemID,4)
dealloc(quantity,4)
unregistersymbol(BoxBase)
unregistersymbol(ItemID)
unregistersymbol(quantity)
dealloc(itcode)
|
Tips:
tip1:
what in rbx is the address of the item at slot 1 of your item box.
then [rbx] is the item's ID at slot 1.
[rbx+04] is the quantity of this item.
tip2:
[slot1 + 0010H] = [slot2]
Thank You!

1. There is no injection point.
2. The code execution would never return, if it was ever executed.
3. You never set "[ItemID]" or "[quantity]", but they're used in the script.
4. You're moving 8 byte registories with a 4 byte offset.
5. You're tell it to assemble outside of any memory.
6. If "jmp toend" was assembled into the new memory for the injection, it would just skip all the added code.
You should go back and do some tutorials, to get a better understanding of what "code injection" is and how it works.

mov rax,[ItemID] // setting 8 byte registry
// [ItemID] is never set, thus it's value is zero
mov [rbx],rax // setting 8 bytes (RBX+0 and RBX+4)

// [quantity] is never set, thus it's value is zero
mov [rbx+04],rax // setting 8 bytes (RBX+4 and RBX+8)

pop rbp
pop rbx
pop rax
toend: // Code execution goes nowhere, just ends here which will likely crash the game.
// you need an injection point and a return for that injection point.
