Posted: Wed Dec 19, 2018 7:46 pm Post subject: [SOLVED] Need help creating a press and hold hotkey toggle.

I'm trying to create a fly script and I want to be able to fly up when space is pressed and held, fly down when left control is held down, and stay level when nothing is pressed.

Example, when nothing is pressed

Code:

code:
//mov [ebx+2C],ecx
test dl,01
jmp return

When space is pressed

Code:

code:
//mov [ebx+2C],ecx
add [ebx+2C],FFF
test dl,01
jmp return

When left control is pressed

Code:

code:
//mov [ebx+2C],ecx
sub [ebx+2C],FFF
test dl,01
jmp return

And here is my original script in case it helps

Code:

[ENABLE]

aobscanmodule(Y_COORDINATE_LOCK,Df.exe,89 4B 2C F6 C2 01) // should be unique
alloc(newmem,$1000)

label(code)
label(return)

newmem:
cmp [ebx+08],00
jne code
//mov [ebx+2C],ecx
add [ebx+2C],FFF
test dl,01
jmp return

code:
mov [ebx+2C],ecx
test dl,01
jmp return

Y_COORDINATE_LOCK:
jmp newmem
nop
return:
registersymbol(Y_COORDINATE_LOCK)

[DISABLE]

Y_COORDINATE_LOCK:
db 89 4B 2C F6 C2 01

unregistersymbol(Y_COORDINATE_LOCK)
dealloc(newmem)

I'm new to lua code but I was hoping if there was one I could use in multiple scripts in multiple games to achieve the same effect.

Thank you.

You could store a variable in your code injection that's modified by CE. See what value it is to do what you want. e.g.:

Thanks, it crashed but I found another solution.

I tried adapting your code to my script, here's what I got.

Code:

[ENABLE]

{$lua}
if syntaxcheck then return end
if t then t.destroy(); t = nil end
local lastVal = 0

t = createTimer()
t.Interval = 100
t.OnTimer = function(t)
local addr = getAddressSafe'direction'
if addr then
local newVal

if isKeyPressed(VK_SPACE) then -- up
newVal = 1
elseif isKeyPressed(VK_LCONTROL) then -- down
newVal = 2
-- etc...
else
newVal = 0
end

if newVal ~= lastVal and writeInteger(addr, newVal) then
lastVal = newVal
end
end
end
{$asm}

aobscanmodule(Z_COORDINATE_LOCK,Df.exe,89 4B 2C F6 C2 01) // should be unique
alloc(newmem,$1000)
alloc(direction,4)
registersymbol(direction)

label(code)
label(return)
label(oldcode)

newmem:
direction:
dd 0

code:
cmp [ebx+08],00
jne oldcode
push eax
mov eax,[direction]
cmp eax,0
jne short @f
pop eax
//mov [ebx+2C],ecx
test dl,01
jmp return
@@:
cmp eax,1
jne short @f
pop eax
//mov [ebx+2C],ecx
add [ebx+2C],FFF
test dl,01
jmp return
@@:
pop eax
//mov [ebx+2C],ecx
sub [ebx+2C],FFF
test dl,01
jmp return

oldcode:
pop eax
mov [ebx+2C],ecx
test dl,01
jmp return

Z_COORDINATE_LOCK:
jmp newmem
nop
return:
registersymbol(Z_COORDINATE_LOCK)

[DISABLE]

Z_COORDINATE_LOCK:
db 89 4B 2C F6 C2 01

{$lua}
if t then t.destroy(); t = nil end
{$asm}
dealloc(direction)
unregistersymbol(direction)
unregistersymbol(Z_COORDINATE_LOCK)
dealloc(newmem)

As previously mentioned, it crashed on me.

But after much research, I managed to find an alternative that workes.

Code:

[ENABLE]

aobscanmodule(Z_COORDINATE_LOCK,Df.exe,89 4B 2C F6 C2 01) // should be unique
alloc(newmem,$1000)

label(code)
label(return)
label(lower)
label(hover)

newmem:

cmp [ebx+08],00
jne code
pushad
pushfd
push 26
call GetAsyncKeystate
shr ax,#15
cmp ax,1
jne lower
popfd
popad
//mov [ebx+2C],ecx
add [ebx+2C],FFF
test dl,01
jmp return

lower:
push 28
call GetAsyncKeystate
shr ax,#15
cmp ax,1
jne hover
popfd
popad
//mov [ebx+2C],ecx
sub [ebx+2C],FFF
test dl,01
jmp return

hover:
popfd
popad
//mov [ebx+2C],ecx
test dl,01
jmp return

code:
mov [ebx+2C],ecx
test dl,01
jmp return

Z_COORDINATE_LOCK:
jmp newmem
nop
return:
registersymbol(Z_COORDINATE_LOCK)

aobscanmodule(LOCK_GROUND,Df.exe,80 4B 6D 20 E9 DC FB FF FF) // should be unique
alloc(newmemw,$1000)

label(codew)
label(returnw)

newmemw:

codew:
//or byte ptr [ebx+6D],20
jmp Df.exe+877DE
jmp returnw

LOCK_GROUND:
jmp newmemw
nop
nop
nop
nop
returnw:
registersymbol(LOCK_GROUND)

[DISABLE]

Z_COORDINATE_LOCK:
db 89 4B 2C F6 C2 01

unregistersymbol(Z_COORDINATE_LOCK)
dealloc(newmem)

LOCK_GROUND:
db 80 4B 6D 20 E9 DC FB FF FF

unregistersymbol(LOCK_GROUND)
dealloc(newmemw)

I think the problem was that I couldn't figure out what to google and I thought lua was the answer. Sorry if I wasted your time, I did at least learn a bit more on lua in case I actually need it in the future.

Thank you.
