LGS_script_template.lua
---------------------------------------------------------------------------------------------
-- LGS_script_template.lua
---------------------------------------------------------------------------------------------
-- Version: 2019-04-19
-- Author: Egor Skriptunoff
--
--
-- This is a template for "Logitech Gaming Software" script file.
-- Four useful features are implemented here:
--
--
-- ------------------------------------------------------------------------------------------
-- FEATURE #1 - random numbers of very high quality
-- ------------------------------------------------------------------------------------------
-- random() -- float 0 <= x < 1
-- random(n) -- integer 1 <= x <= n
-- random(m, n) -- integer m <= x <= n
-- ------------------------------------------------------------------------------------------
-- This new function is a drop-in replacement for standard Lua function "math.random()".
-- It generates different sequences of random numbers on every profile load, you don't need to set seed (forget about "math.randomseed").
-- The random number generator adsorbs entropy from every event processed by OnEvent().
-- It takes into account everything: event type, button index, mouse position on the screen, current date and running time.
-- This entropy is converted by SHAKE128 (SHA3 hash function) into stream of pseudo-random bits.
-- That's why function "random()" returns random numbers having excellent statistical properties.
-- Actually, after user clicked mouse buttons 100-200 times (no hurry please),
-- these pseudo-random numbers might be considered cryptographically strong.
--
-- ------------------------------------------------------------------------------------------
-- GetEntropyCounter()
-- ------------------------------------------------------------------------------------------
-- This function returns estimation of lower bound of number of random bits consumed by random numbers mixer
-- (wait until it reaches 256 prior to generating crypto keys)
--
-- ------------------------------------------------------------------------------------------
-- SHA3_224(message)
-- SHA3_256(message)
-- SHA3_384(message)
-- SHA3_512(message)
-- SHAKE128(digest_size_in_bytes, message)
-- SHAKE256(digest_size_in_bytes, message)
-- ------------------------------------------------------------------------------------------
-- SHA3 hash functions are available.
-- SHA3_224, SHA3_256, SHA3_384, SHA3_512 generate message digest of fixed length
-- SHAKE128, SHAKE256 generate message digest of potentially infinite length
-- Example #1:
-- How to get SHA3-digest of your message:
-- SHA3_224("The quick brown fox jumps over the lazy dog") == "d15dadceaa4d5d7bb3b48f446421d542e08ad8887305e28d58335795"
-- SHAKE128(5, "The quick brown fox jumps over the lazy dog") == "f4202e3c58"
-- Example #2:
-- How to convert your password into infinite sequence of very high quality random bytes (the same password will give the same sequence):
-- -- start the sequence, initialize it with your password
-- local get_hex_byte = SHAKE128(-1, "your password")
-- while .... do
-- -- get next number from the inifinite sequence
-- local next_random_byte = tonumber(get_hex_byte(), 16) -- integer 0 <= n <= 255
-- local next_random_dword = tonumber(get_hex_byte(4), 16) -- integer 0 <= n <= 4294967295
-- -- how to construct floating point number 0 <= x < 1
-- local next_random_float = (tonumber(get_hex_byte(3), 16) % 2^21 * 2^32 + tonumber(get_hex_byte(4), 16)) / 2^53
-- ....
-- end
--
--
--
-- ------------------------------------------------------------------------------------------
-- FEATURE #2 - you can see the output of print() in the LGS script editor
-- ------------------------------------------------------------------------------------------
-- print(...)
-- ------------------------------------------------------------------------------------------
-- Now this function displays messages in the bottom window of the script editor.
-- You can use "print()" just like in standard Lua!
-- When using "print()" instead of "OutputLogMessage()", don't append "\n" to a message.
--
--
--
-- ------------------------------------------------------------------------------------------
-- FEATURE #3 - handy names for mouse buttons
-- ------------------------------------------------------------------------------------------
-- "L", "R", "M" are now names for the first three mouse buttons
-- ------------------------------------------------------------------------------------------
-- There is an unpleasant feature in LGS: Logitech and Microsoft enumerate mouse buttons differently.
-- In OnEvent("MOUSE_BUTTON_PRESSED", arg, "mouse") parameter 'arg' uses Logitech order:
-- 1=Left, 2=Right, 3=Middle, 4=Backward(X1), 5=Forward(X2), 6,7,8,...
-- In PressMouseButton(button) parameter 'button' uses Microsoft order:
-- 1=Left, 2=Middle, 3=Right, 4=X1(Backward), 5=X2(Forward)
-- As you see, Right and Middle buttons are swapped; this is very confusing.
-- To make your code more clear and less error-prone, try to avoid using numbers 1, 2 and 3.
-- Instead, use strings "L", "R", "M" for the first three mouse buttons.
-- Two modifications have been made:
-- 1) The following functions now accept strings "L", "R", "M" as its argument:
-- PressMouseButton(),
-- ReleaseMouseButton(),
-- PressAndReleaseMouseButton(),
-- IsMouseButtonPressed()
-- 2) 'mouse_button' variable was defined inside OnEvent() function body, it contains:
-- either string "L", "R", "M" (for the first three mouse buttons)
-- or number 4, 5, 6, 7, 8,... (for other mouse buttons).
-- These modifications don't break compatibility with your old habits.
-- You can still use numbers if you want:
-- if event == "MOUSE_BUTTON_PRESSED" and arg == 2 then -- RMB event
-- PressAndReleaseMouseButton(3) -- simulate pressing RMB
-- But using strings improves readability:
-- if event == "MOUSE_BUTTON_PRESSED" and mouse_button == "R" then
-- PressAndReleaseMouseButton("R")
--
--
--
-- ------------------------------------------------------------------------------------------
-- FEATURE #4 - Pixel-oriented functions for mouse
-- ------------------------------------------------------------------------------------------
-- GetMousePositionInPixels()
-- SetMousePositionInPixels(x,y)
-- ------------------------------------------------------------------------------------------
-- You can now get and set mouse cursor position IN PIXELS.
-- GetMousePositionInPixels() returns 6 values (probably you would need only the first two):
-- x_in_pixels, -- integer from 0 to (screen_width-1)
-- y_in_pixels, -- integer from 0 to (screen_height-1)
-- screen_width_in_pixels, -- for example, 1920
-- screen_height_in_pixels, -- for example, 1080
-- x_64K, -- normalized x coordinate 0..65535, this is the first value returned by "GetMousePosition()"
-- y_64K -- normalized y coordinate 0..65535, this is the second value returned by "GetMousePosition()"
-- As you know, standard LGS function MoveMouseRelative() is limited to narrow distance range from -127 to +127 pixels.
-- Now you can move mouse cursor more than 127 pixels away from its current position:
-- local current_x, current_y = GetMousePositionInPixels()
-- SetMousePositionInPixels(current_x + 300, current_y + 200)
-- This method of relative moving works fine even when "Acceleration" flag is set in "Pointer settings" (the third icon from the left, at the bottom of the page).
-- As you probably know, MoveMouseRelative() works incorrectly when this flag is set: the real distance not equals to the number of pixels requested.
--
-- Don't forget that you must wait a bit (for example, Sleep(5)) after simulating mouse move, button press or button release.
--
--
--
-- Important note:
-- This script requires one second for initialization.
-- In other words, when this LGS profile is started, you will have to wait for 1 second before playing.
-- Explanation:
-- Every time this profile is activated (and every time when your game changes the screen resolution)
-- the process of automatic determination of screen resolution is started.
-- This process takes about one second.
-- During this process, mouse cursor will be programmatically moved some distance away from its current location.
-- This cursor movement might be a hindrance to use your mouse, so just wait until the cursor stops moving.

@Egor-Skriptunoff thank you for your reply, I have two game profiles that I pasted your script on both of profiles because I don't know if it's possible to have it load once and activated for all different game profiles. So everytime I open one of two games or alt tab between them, script is loaded again if I enable LGS to auto detect game. Sometimes, it crashes on switching only once. I have one of the early G502 which shows anomaly such as if I lower its polling rate, cursor is accelerated and vice versa. Could be my mouse is faulty and can not handle script well.

I wanted to include some extra info if it helps something, thank you again Egor for your script.

@magnapeccatrix -

I don't know if it's possible to have it load once and activated for all different game profiles.

No.
It looks like LGS creates new Lua VM on every profile switch.

The behavior of the script does not depend on the polling rate of your mouse.

If you don't need functions Get/SetMousePositionInPixels you may remove lines 172-275 from the script or replace them with single statement Sleep(100). This might help switching profiles faster, but I did not test it.

Thanks! This is a fantastic head start for what I'm after. cheers
