I'm trying to run a script that reads a value, if it is below it activates an "F1" key.
however I want it to run in the target program, even if I am in Opera

Code:

-- Make sure the game process is open
local al = getAddressList()

-- Defines the F1 key (keycode 0x70 for F1)
location F1_KEY = 0x70
local gamePID = 9596 -- Replace with the game's actual PID

-- Function to send the F1 key to the game, using the game window based on the PID
function sendF1ToGame()
-- Finds the window associated with the game's PID
local hwnd = findWindowByProcessID(gamePID)

if hwnd ~= nil then
-- Sends the message to press and release F1
postMessage(hwnd, 0x0100, F1_KEY, 0) -- 0x0100 is the WM_KEYDOWN message (key press)
postMessage(hwnd, 0x0101, F1_KEY, 0) -- 0x0101 is the WM_KEYUP message (release the key)
else
end
end

-- Function to monitor the value in memory
function monitorValue()
-- Here we define the address and value to be monitored.
-- Replace "0x3D0F2108" with the correct address of the value.
local address = 0x3D0F2108

-- Reads the value of the address
local value = readInteger(address)

-- If the value is less than 700, send the F1 command
if value then
if value < 700 then
sendF1ToGame()
else
end
else
end
end

-- Configure the timer to check the value every second (1000 ms)
timer = createTimer(nil, true)
timer.Interval = 1000 -- 1 second
timer.OnTimer = monitorValue

You mean, CE would sent a keypress to the process it is attached to, right?
I think I ran into this problem earlier and there was no solution.
I hope I'm wrong though!
