HUD Blur?

[SteppuFIN]

Hey Facepunch!

I was doing today hud for my server and then i wanted to make draw.RoundedBoxEx blurred.

How can i do that?

[lua]
local blur = Material("pp/blurscreen")
local function DrawBlur(panel, amount)
local x, y = panel:LocalToScreen(0, 0)
local scrW, scrH = ScrW(), ScrH()
surface.SetDrawColor(255, 255, 255)
surface.SetMaterial(blur)
for i = 1, 3 do
blur:SetFloat("$blur", (i / 3) * (amount or 6))
blur:Recompute()
render.UpdateScreenEffectTexture()
surface.DrawTexturedRect(x * -1, y * -1, scrW, scrH)
end
end
[/lua]

Then use DrawBlur(Panel, BlurAmt)

Sorry, but how i am supposed to convert PANEL to Draw.RoundedBoxEx?

[Mrkrabz]

Do it within the Paint function for example:

[lua]
Frame.Paint = function( self, w, h )
DrawBlur(self, 2)
draw.RoundedBox( 5, 0, 0, w, h, Color( 0, 0, 0, 200 ) )
end
[/lua]

I think he is talking about using it outside of Derma for his HUD. I guess you could try using that DrawBlur function but changing X and Y to your own variables

[AIX-Who]

local blur = Material("pp/blurscreen")
local function DrawBlurRect(x, y, w, h)
	local X, Y = 0,0

	surface.SetDrawColor(255,255,255)
	surface.SetMaterial(blur)

	for i = 1, 5 do
		blur:SetFloat("$blur", (i / 3) * (5))
		blur:Recompute()

		render.UpdateScreenEffectTexture()

		render.SetScissorRect(x, y, x+w, y+h, true)
			surface.DrawTexturedRect(X * -1, Y * -1, scrW, scrH)
		render.SetScissorRect(0, 0, 0, 0, false)
	end
   
   draw.RoundedBox(0,x,y,w,h,Color(0,0,0,205))
   surface.SetDrawColor(0,0,0)
   surface.DrawOutlinedRect(x,y,w,h)
   
end

There's that if it does not work for you, Credit to Chessnut
