Sideway Movement When Moving Cursor Horizontally Only - lua

Question

Trying to make a LUA script that gets a mouse position and then inputs key movement accordingly
If the mouse is moving towards the right, I want the character to move left and vice versa.
Found bunch of codes here online and tried stitching them but no consistent result
EnablePrimaryMouseButtonEvents(true);
local distance_horiz = 2 -- x, pixels
local distance_vert = 2 -- x, pixels
local key_press_delay = 0 -- y, ms
local screen_width = 2560 -- set your game screen resolution here
local screen_height = 1440
--------------------------------------------------------------------
local active
function OnEvent(event, arg)
if event == "MOUSE_BUTTON_PRESSED" and arg == 1 then
repeat
if IsMouseButtonPressed(1) then
local horiz, vert, horiz_key, vert_key, horiz_key_tm, vert_key_tm = 0, 0
local prev_MMB, prev_x, prev_y = true
repeat
Sleep(10)
local MMB = IsMouseButtonPressed(2)
local exit = MMB and not prev_MMB
prev_MMB = MMB
local x, y = GetMousePosition()
x = math.floor((x + (0.5 + 2^-16)) * (screen_width-1) / (2^16-1))
y = math.floor((y + (0.5 + 2^-16)) * (screen_height-1) / (2^16-1))
x, y, prev_x, prev_y = x - (prev_x or x), y - (prev_y or y), x, y
horiz, vert = horiz + x, vert + y
local tm = GetRunningTime()
-- horiz
if tm >= (horiz_key_tm or 0) then
if math.abs(horiz) >= distance_horiz then
local new_key
if horiz > 0 then
horiz, new_key = horiz - distance_horiz, "D"
else
horiz, new_key = horiz + distance_horiz, "A"
end
if new_key ~= horiz_key then
if horiz_key then
ReleaseKey(horiz_key)
end
PressKey(new_key)
end
horiz_key, horiz_key_tm = new_key, (horiz_key_tm or tm) + key_press_delay
elseif horiz_key then
ReleaseKey(horiz_key)
horiz_key, horiz_key_tm = nil
end
end
until not IsMouseButtonPressed(1)
end
until not IsMouseButtonPressed(3)
end
end

Answer 1

To turn the script on press Middle Mouse Button.
To turn the script off press MMB again.
While the script is on, horizontal mouse movement is echoed by "A"/"D" keys
local distance_horiz = 20 -- each 20 pixels makes one key-press A/D
local screen_width = 2560 -- set your game screen resolution here
local active
function OnEvent(event, arg)
if event == "PROFILE_ACTIVATED" then
EnablePrimaryMouseButtonEvents(true)
elseif event == "MOUSE_BUTTON_PRESSED" and arg == 3 then -- MMB
active = not active
if active then
local horiz, prev_x, exit, key = 0
repeat
Sleep(10)
local MMB = IsMouseButtonPressed(2)
exit, active = MMB and not active, MMB
local x = GetMousePosition()
x = math.floor((x + (0.5 + 2^-16)) * (screen_width-1) / (2^16-1))
horiz, prev_x = horiz + x - (prev_x or x), x
if math.abs(horiz) >= distance_horiz then
if horiz > 0 then
horiz, key = horiz - distance_horiz, "A"
else
horiz, key = horiz + distance_horiz, "D"
end
PressAndReleaseKey(key)
end
until exit
end
end
end
