You need isMouseInPosition function.

function isMouseInPosition(a, b, c, d) 
    if not isCursorShowing() then return end 
    local x, y = getCursorPosition() 
    x, y = x*sx, y*sy 
    if x >= a and y >= b and x <= a+c and y <= b+d then 
        return true 
    end 
    return false 
end

didn't understand that can you please give me an example with numbers?!
