Speedometer

[Matevsz]

hello, how to move the speedometer at the center of the screen? it is on the right side of

  
c_XOffset = 10 
c_YOffset = 10 
c_ImageW = 200 
c_ImageH = 200 
c_BarW = 0 
c_BarH = 0 
c_BarYOffset = 70 
  
function initGui() 
    if disc then 
        destroyElement(disc) 
    end 
    g_screenWidth, g_screenHeight = guiGetScreenSize() 
    local scale 
    if c_EnableScaling then 
        scale = (g_screenWidth/1000 + g_screenHeight/850)/2 
    else 
        scale = 1 
    end 
    g_XOffset = round(c_XOffset*scale) 
    g_YOffset = round(c_YOffset*scale) 
    g_ImageW = round(c_ImageW*scale) 
    g_ImageH = round(c_ImageH*scale) 
    g_BarW = round(c_BarW*scale) 
    g_BarH = round(c_BarH*scale) 
    g_BarYOffset = round(c_BarYOffset*scale) 
    disc = guiCreateStaticImage(g_screenWidth - g_ImageW - g_XOffset, g_screenHeight - g_ImageH - g_YOffset, g_ImageW, g_ImageH, "disc.png", false) 
    x, y = guiGetPosition(disc, false) 
end

c_XOffset = 0 
c_YOffset = 0

at all times to the right

I don't get what you mean..

Here is the entire code

I changed to:

  
c_XOffset = 0 
c_YOffset = 0 
  

but still it is on the right
