local g_Window = nil 
local clBt = {} 
local blurry = 'images/1.png' 
local normal = 'images/2.png' 
addCommandHandler("window", 
function () 
    if g_Window then return end 
  
    g_Window = {} 
 for i,v in ipairs(clBt) do 
            if isElement(v) then 
                destroyElement(v) 
            end 
        end 
    local screenWidth, screenHeight = guiGetScreenSize() 
    faWidth, faHeight = 477,419 
    local left = screenWidth/2 - faWidth/2 
    local top = screenHeight/2 - faHeight/2 
  
    fa = guiCreateGridList(left, top, faWidth, faHeight, false) 
guiSetAlpha(fa, 0.62) 
    g_Window.closeBtn = guiCreateStaticImage(436, 0, 41, 32, ":admin/client/images/error.png", false, fa) 
    clBt = guiCreateStaticImage(117, 96, 292, 267, normal, false, fa)  
    guiSetEnabled(fa, false) 
    guiSetVisible(fa, false) 
    g_Window.startTime = getTickCount() 
    g_Window.startSize = {0, 0} 
    g_Window.endSize = {faWidth, faHeight} 
    g_Window.endTime = g_Window.startTime + 1000 
    addEventHandler("onClientRender", getRootElement(), popWindowUp) 
end) 
     
 addEventHandler("onClientMouseEnter",root, 
    function() 
        for i,v in ipairs(clBt) do 
            if source == v then 
                if not getElementData(v, "sign") then 
                    guiStaticImageLoadImage(v, blurry) 
                end 
            end 
        end 
    end

    end 
  
    if not g_Window then return end 
  
    showCursor(false) 
    guiSetEnabled(fa, false) 
  
    local screenWidth, screenHeight = guiGetScreenSize() 
    local posX, posY = guiGetPosition(fa, false) 
  
    g_Window.startTime = getTickCount() 
    g_Window.startSize = {faWidth, faHeight} 
    g_Window.startCenter =

end 
  
function popWindowUp() 
    local now = getTickCount() 
    local elapsedTime = now - g_Window.startTime 
    local duration = g_Window.endTime - g_Window.startTime 
    local progress = elapsedTime / duration 
  
    local width, height, _ = interpolateBetween (  
        g_Window.startSize[1], g_Window.startSize[2], 0,  
        g_Window.endSize[1], g_Window.endSize[2], 0,  
        progress, "OutElastic") 
  
    guiSetSize(fa, width, height, false) 
  
    local screenWidth, screenHeight = guiGetScreenSize() 
    guiSetPosition(fa, screenWidth/2 - width/2, screenHeight/2 - height/2, false) 
  
    if not guiGetVisible(fa) then 
        guiSetVisible(fa, true) 
        guiBringToFront(fa) 
    end 
  
    if now >= g_Window.endTime then 
        guiSetEnabled(fa, true) 
  
        guiBringToFront(fa) 
        removeEventHandler("onClientRender", getRootElement(), popWindowUp)
