Blur

I got some questions about layering blur under a roundedbox. This is actually the first time im using blur so yeah.
For example i want a layer behind this roundedbox. How would i do this?


draw.RoundedBox( 1500, 1500, 1500, 1500, 1500, Color(255, 255, 255, 255) )
#2 

surface.DrawBlur = function(x, y, w, h, amount)
	surface.SetDrawColor(color_white)
	surface.SetMaterial(blur)

	for i = 1, 3 do
		blur:SetFloat("$blur", (i / 3) * (amount or 6))
		blur:Recompute()

		render.UpdateScreenEffectTexture()

		render.SetScissorRect(x, y, x + w, y + h, true)
			surface.DrawTexturedRect(0, 0, ScrW(), ScrH())
		render.SetScissorRect(0, 0, 0, 0, false)
	end
end




surface.DrawBlur(1500, 1500, 1500, 1500)
draw.RoundedBox(1500, 1500, 1500, 1500, 1500, Color(0, 0, 0, 150))
#3

That would draw a blurred rect with a “circle” inside

#4 


local function DrawBlur( p, a, d )
	local x, y = p:LocalToScreen(0, 0)
	surface.SetDrawColor( 255, 255, 255 )
	surface.SetMaterial( blur )
	for i = 1, d do
		blur:SetFloat( "$blur", (i / d ) * ( a ) )
		blur:Recompute()
		render.UpdateScreenEffectTexture()
		surface.DrawTexturedRect( -x, -y, ScrW(), ScrH() )
	end
end





Bleh.Paint = function( self, w, h )
	DrawBlur(self, 1, 2)
	draw.RoundedBox( 1500, 1500, 1500, 1500, 1500, Color(255, 255, 255, 255) )
end

I used this code for my scoreboard which used derma and I think it will work like that (not sure though, might have miss or screwed up something knowing me). There is a link to HUD blur with a Draw.RoundedBoxEx, here is the link: http://forum.facepunch.com/showthread.php?t=1464767

Can’t you do this with the stencil library?

I’m just starting to scratch the surface of GUI so be free to rate boxes :stuck_out_tongue:

EDIT: I’m mainly looking at this line



v:SetModelScale(1.0+math.Rand(0.01,0.013),0) --slightly fuzzy, looks better this way
#6

I want to put this in a other function would this work aswell?


 hook.Add("HUDPaint", "HUD", function()
	local client = LocalPlayer() 
	local curHealth = client:Health() 

	if (health == curHealth) then 
		if (time ~= 0) then
			if (CurTime() > time) then
				return 
			end
		else 
			time = CurTime() + 0
		end
	else 
		health = 100
		time = 0
	end
	
end)
#7

But the method of creating global function in the surface list will make his addon vulnerable as everyone will be able to call it where the addon is installed. I would go for a local function instead.

#8

It doesn’t appear?


 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(5, 50, 50, 50, 50,Color(0,0,0,205))
   surface.SetDrawColor(0,0,0)
   surface.DrawOutlinedRect(50, 50, 50, 50)
   
end
