[DriFtyZ]

Hello mta community, im new to lua scripting (day 2) and i want to make a gui menu that has options inside to enable disable shaders but for now i can't even reach the way how the windows gets visible when i pree a key (F2 in my situation) can you help me out a bit? thanks in advance

Here's my code below (yes i checked mta wiki)
 

water = {}
Contrast = {}
Close = {}
carpaint = {}
contrast = {}
graphics = {}
detail = {}
addEventHandler("onClientResourceStart", resourceRoot,
    function GuiWindow ()
        graphics.window = guiCreateWindow(625, 207, 451, 315, "Graphics Menu", false)
        guiWindowSetSizable(graphics.window, false)
        guiSetAlpha(graphics.window, 0.85)
        guiSetProperty(graphics.window, "CaptionColour", "FFB1794C")
		
		carpaint.checkbox = guiCreateCheckBox(192, 53, 16, 20, "", false, false, graphics.window)
        water.checkbox = guiCreateCheckBox(192, 100, 17, 17, "", false, false, graphics.window)
        constrast.checkbox = guiCreateCheckBox(192, 144, 14, 16, "", false, false, graphics.window)
        detail.checkbox = guiCreateCheckBox(192, 187, 15, 15, "", false, false, graphics.window)
		
        Close.button = guiCreateButton(149, 243, 152, 49, "Close", false, graphics.window)
		
        guiSetProperty(Close.button, "NormalTextColour", "FFAAAAAA")
        carpaint.label = guiCreateLabel(39, 53, 86, 25, "Car Reflections", false, graphics.window)
        guiSetFont(carpaint.label, "default-bold-small")
        water.label = guiCreateLabel(39, 100, 104, 24, "Water Reflections", false, graphics.window)
        guiSetFont(water.label, "default-bold-small")
        contrast.label = guiCreateLabel(39, 142, 104, 26, "Contrast", false, graphics.window)
        guiSetFont(contrast.label, "default-bold-small")
        detail.label = guiCreateLabel(39, 186, 104, 26, "Detail", false, graphics.window)
        guiSetFont(detail.label, "default-bold-small")		
	end
)

bindKey ( "F2", "down", F2) 

function F2 ()
    local state = guiGetVisible ( graphics.window )
	if state == false then
		guiSetVisible (graphics.window, true)
		showCursor (true)
	else
		guiSetVisible (graphics.window, false)
		showCursor (false)
	end
end

Test this

water = {}
Contrast = {}
Close = {}
carpaint = {}
contrast = {}
graphics = {}
detail = {}
        graphics.window = guiCreateWindow(625, 207, 451, 315, "Graphics Menu", false)
        guiWindowSetSizable(graphics.window, false)
        guiSetAlpha(graphics.window, 0.85)
        guiSetProperty(graphics.window, "CaptionColour", "FFB1794C")
		guiSetVisible (graphics.window, false)
		carpaint.checkbox = guiCreateCheckBox(192, 53, 16, 20, "", false, false, graphics.window)
        water.checkbox = guiCreateCheckBox(192, 100, 17, 17, "", false, false, graphics.window)
        constrast.checkbox = guiCreateCheckBox(192, 144, 14, 16, "", false, false, graphics.window)
        detail.checkbox = guiCreateCheckBox(192, 187, 15, 15, "", false, false, graphics.window)
		
        Close.button = guiCreateButton(149, 243, 152, 49, "Close", false, graphics.window)
		
        guiSetProperty(Close.button, "NormalTextColour", "FFAAAAAA")
        carpaint.label = guiCreateLabel(39, 53, 86, 25, "Car Reflections", false, graphics.window)
        guiSetFont(carpaint.label, "default-bold-small")
        water.label = guiCreateLabel(39, 100, 104, 24, "Water Reflections", false, graphics.window)
        guiSetFont(water.label, "default-bold-small")
        contrast.label = guiCreateLabel(39, 142, 104, 26, "Contrast", false, graphics.window)
        guiSetFont(contrast.label, "default-bold-small")
        detail.label = guiCreateLabel(39, 186, 104, 26, "Detail", false, graphics.window)
        guiSetFont(detail.label, "default-bold-small")		
	

function F2 ()
    local state = guiGetVisible ( graphics.window )
	if state == false then
		guiSetVisible (graphics.window, true)
		showCursor (true)
	else
		guiSetVisible (graphics.window, false)
		showCursor (false)
	end
end
bindKey ( "F2", "down", F2)

thanks a lot it worked but i can't understand why the panel opens up while starting the resource by default even since the event handle is gone now

Add this at line 29 

 

guiSetVisible(graphics.window, false)
