Function to draw an Overlay

[P4sca1]

Hello,
in the spawn menu, there's a tab where you can select an overlay. I'm wondering which function is able to do this?

AFAIK, it's just drawing a material over the screen. You can accomplish the same results by using the surface library inside a HUDPaint hook.

For example:

local Overlay = Material( "effects/combine_binocoverlay" )

hook.Add( "HUDPaint", "MaterialOverlay", function()

    surface.SetMaterial( Overlay )
    surface.DrawTexturedRect( 0, 0, ScrW(), ScrH() )

end )

You can also accomplish by using a console command which I cannot remember right now.

Thanks for the code, I will test it out.

The code is doing exactly what I wanted. Thank you!
However, it is drawn after all other HUD Elements. I tried using HUDPaintBackground, but then it is not drawing at all. Does anybody have an idea?

You can do this

local Overlay = Material( "effects/combine_binocoverlay" )

local function drawOverlay()
    surface.SetMaterial( Overlay )
    surface.DrawTexturedRect( 0, 0, ScrW(), ScrH() )
end

if(!hook.GetTable()["HUDPaint"]["MaterialOverlay"]) then
    table.insert(hook.GetTable()["HUDPaint"],1,{MaterialOverlay = drawOverlay })
else
    hook.GetTable()["HUDPaint"]["MaterialOverlay"] = drawOverlay
end

this has been untested, but basically push that funciona into the hook table and runs drawOverlay

This is not working, without giving an error.

I were going to suggest that, but then he looked happy about this :v
Anyway, i would recommend RCE since you can use screen space effects like blur or bumpmaps, thing that you cant paint in hudhook

Restart your server, because this won't modify the herarchy created with in the table.insert, anyway, i'm not sure if table.insert index parameter, inserts inside non-number keys

Yes it is, thank you!

local function swrp_draw_mask()
	local mask = "effects/combine_binocoverlay"
	DrawMaterialOverlay(mask, 0)
end

hook.Add("RenderScreenspaceEffects", "swrp_draw_mask", swrp_draw_mask)

This code is doing what expected.
