So my Problem is that if I execute an function in the Game crashes the Game



Example:

[CODE=cea][ENABLE]

alloc(thread,248)

createthread(thread)

registersymbol(thread)

label(jump1)

label(jump2)

label(jump3)



thread:

push rbp

mov rbp,rsp

push rsi

sub rsp,08 { 8 }

mov rsi,rcx

movzx eax,byte ptr [rsi+000000C4]

test eax,eax

jne jump1

mov byte ptr [rsi+000000C4],01 { 1 }

jmp jump2

jump1:

movzx eax,byte ptr [rsi+000000C5]

test eax,eax

jne jump3

mov byte ptr [rsi+000000C5],01 { 1 }

jmp jump2

jump3:

mov byte ptr [rsi+000000C4],00 { 0 }

mov byte ptr [rsi+000000C5],00 { 0 }

jump2:

mov rcx,rsi

sub rsp,20 { 32 }

mov r11,0000000008DC10A0 { [98EF5BE8] }

call r11

add rsp,20 { 32 }

mov rsi,[rbp-08]

leave

ret

The thing that function should do is toggle an Overlay that you can toggle with the specific debug command but I want it to be toogled through this script but when I activate it, it just crashes the game. I also tried some other functions and they all crash the game too. Therefore I think I'm doing something wrong.

What values are you PUSHing to the stack?



I think you need to figure out what arguments the function needs and PUSH those to the stack.

iirc that game uses mono and you have to attach the thread to mono see [URL='https://forum.cheatengine.org/viewtopic.php?p=5722879&sid=dbe80103f49836a7f0c272e5a2bee44a#5722879']DBs comment here[/URL]

Though it also looks like you just copy-pasted a function and expect it to work without actually setting the expected arguments in registers or pushing a return address on the stack (it [I]expects [/I]to be [B]call[/B]ed after all, not simply run).

I don't really know how I can attach the thread to mono. I've never done anything similar to this before and therefore I'm a noob in this kind of Stuff. And yes I just copy-pasted the function.

See my [B]BattleTech[/B] table [URL='https://fearlessrevolution.com/threads/battletech.6603/page-12#post-45978']here[/URL]. Check [I]Cheat Handler[/I] script; that's how you attach/detach. Also, I highly doubt this is valid every time you open the game:



[code=CEA]

mov r11,0000000008DC10A0 { [98EF5BE8] }

[/code]

Ok that should work thanks but I still have one question: What does the "@@:" and the "short @f" mean?

"@@" is a generic label; doesn't stand for anything, it's just used so "je short @f" knows where to hop to. JE will hop to @@ label; @f = forward; @b = backwards. Keep in mind @f/@b will jump to first encountered label, even if it's not @@.

Oh ok thanks :)

I still have another little question: In your Script you have for exaple "GodMode_do" and I wan't to know if that is the function that you find if you search for it in mono or if it is a made up name because the Script has to know where it has to call so thats what I think.



Edit: I found it out but under "ToggleEnableConsole_do:", how did you find out what you had to put there like what I don't under stand is:

[CODE=cea]mov cl,al

test cl,cl

sete cl[/CODE]
