I want to make a fly car but I don't know how to add angles of rotation direction to velocity +230 and +238 Coordinate X Y direction. Here is the LUA fly car script, it works, but I need to do this in an aa script for smoothness and convenience.

Code:

{$LUA}
[ENABLE]

function SpeedHack33()

Xp = readFloat('[_Speed33]+230') -- X coordinate position velocity
Xv = readFloat('[_Speed33]+170') -- Coordinate X direction
X = Xp+Xv*1-- Calculate the new position coordinate

Zp = readFloat('[_Speed33]+238')
Zv = readFloat('[_Speed33]+178')-- Coordinate Y direction
Z = Zp+Zv*1

if isKeyPressed(VK_SHIFT)then
writeFloat('[_Speed33]+230', X) -- We write the new coordinate of the velocity position X +0
writeFloat('[_Speed33]+238', Z) -- velocity Y

end
end

t=createTimer(nil)
timer_setInterval(t, 1)
timer_onTimer(t, SpeedHack33)
timer_setEnabled(t, true)

[DISABLE]

timer_setEnabled(t, false)

Code:

[ENABLE]
aobscanmodule(Fly2,SnowRunner.exe,F3 0F 10 89 34 02 00 00)
alloc(newmem,$1000,Fly2)// "SnowRunner.exe"+B09DD2

pop rcx

I think you are missing a fundamental difference between the two. The LUA script is using its timer to run "independently". The AA code runs only when that code you hooked is invoked.

the code is just an example, I just need to add two offsets, [rcx+170] and [rcx+178] correctly, to the Script.

LUA

Code:

Xp = readFloat('[_Speed33]+230') -- X coordinate position velocity
Xv = readFloat('[_Speed33]+170') -- Coordinate X direction
X = Xp+Xv*1-- Calculate the new position coordinate

ASM

Code:

mov rax,[_Speed33]
movss xmm0,[rax+230]
addss xmm0,[rax+170]

LUA

Code:

Zp = readFloat('[_Speed33]+238')
Zv = readFloat('[_Speed33]+178')-- Coordinate Y direction
Z = Zp+Zv*1

ASM

Code:

mov rax,[_Speed33]
movss xmm1,[rax+238]
addss xmm1,[rax+178]

the game hangs when you press VK_SHIFT, what could it be, maybe the rax register?

Depending on where you inject the code, you might be overwriting a critical value in the rax register. Only write to rax if you know that the game doesn't need the register later on.

Either save the rax value and restore it manually after you're done, or find a register that the code you're hooking doesn't need later on and that you can overwrite freely.

I tried other registers and there is no crash, they are free
but there is no acceleration, the script for some reason does not work
and an error when I confirm the script

I don't understand where to insert this?

mov rax,[_Speed33]
movss xmm0,[rax+230]
addss xmm0,[rax+170]

Can you give me more details about the floats? What should I do? I'm confused?

Non-related but you'd rather use pushad/popad rather than pushing each register individually
