playerinfo hud

[MrRalgoman]

I'm trying to figure out the best way of drawing an element to my hud like the default darkrp playerinfo hud (the one that is above a player). I found a 3d2d function snippet that allows me to use draw funcs above a head but there are a few issues I have ran into with this.

First off, is the correct way to go about drawing a player info hud? Is there a better way of doing it?

The first screenshot is self explanatory, how could I make it so that players can't see their own info, but still can see other players info.

For the second screenshot I am trying to add the blur effect like the rest of the hud to this as well.

local function DrawBlurRect(x, y, w, h, amount, heavyness)
	surface.SetDrawColor(255, 255, 255, 255)
	surface.SetMaterial(blur)

	for i = 1, heavyness 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 * -1, 0 * -1, ScrW(), ScrH())
		render.SetScissorRect(0, 0, 0, 0, false)
	end
end

function plyinfohud()

	local ply = LocalPlayer()

	local HeadPos, HeadAng = ply:GetBonePosition( ply:LookupBone("ValveBiped.Bip01_Head1") )
	local Pos = HeadPos + Vector(0, 5, 40)

	local Ang = EyeAngles()
	Ang:RotateAroundAxis( Ang:Right(), 90 )
	Ang:RotateAroundAxis( Ang:Up(), -90 )

	cam.Start3D2D(Pos, Ang, 0.1)

		-- draw.RoundedBox(0,-100,-200,200,100,Color(255,255,255))
		DrawBlurRect( -100, -100, 200, 100, 5, 4 )
		draw.RoundedBox( 10, -100, 100, 200, 100, Color( 0, 0, 0, 175 ) )
		draw.SimpleText(ply:Nick(),"plyhud",0,150,Color(255,255,255),1,1)
	
	cam.End3D2D()

end

hook.Add("PostDrawOpaqueRenderables", "plyinfo", plyinfohud)

Could the reason it is not drawing possibly have something to do with the 2d/3d rendering stuff? I can't see why because draw.box is 2d, but the 3d2d cam allows it to work. Thoughts??

Thanks in advance for any help!

You were talking about the blur

To answer your other question, you could just use 2D for this if you want - all you need to do is find the player's head position and then use [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/Vector/ToScreen]Vector:ToScreen[/url] to draw some 2D text in the 2D coordinates above it

local function plyinfohud()

	for _, ply in pairs(player.GetAll()) do

		if ply ~= LocalPlayer() then -- Don't draw our own name above our head

			local HeadPos, HeadAng = ply:GetBonePosition( ply:LookupBone("ValveBiped.Bip01_Head1") )
			local Pos = HeadPos:ToScreen()
			Pos.y = Pos.y - 50

			DrawBlurRect( Pos.x - 100, Pos.y - 50, 200, 100, 5, 4 )
			draw.RoundedBox( 10, Pos.x - 100, Pos.y - 50, 200, 100, Color( 0, 0, 0, 175 ) )
			draw.SimpleText( ply:Nick(), "plyhud", Pos.x, Pos.y, color_white, TEXT_ALIGN_CENTER, TEXT_ALIGN_CENTER )

		end
	end

end

hook.Add( "HUDPaint", "plyinfo", plyinfohud )

That code needs a bit of adjustment to make it look actually good but it should give you an idea - it's a bit simpler this way

Also, you should really be using [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/surface/GetTextSize]surface.GetTextSize[/url] so you draw the box the actual size of the player's name

[MrRalgoman]

[QUOTE=MPan1;51650661]It's because you need to loop through all players, not just use the local player. How do you expect it to draw for all the players if you only use yourself?

Well yes of course, I only had that formatted just so I could understand how it all worked. Do you have insight on the blur function I am using and why it may not be drawing?

[MysteryPancake]

Maybe it only works in 2D or something? I tried testing it but you didn't define the 'blur' variable that you're using SetMaterial with, so it didn't work. I just assumed you defined it yourself before somewhere

[editline]10th January 2017[/editline]

I'm sure you would've noticed if it wasn't defined though, it spammed my console with errors. If you post what it is I could try testing it

[editline]10th January 2017[/editline]

Sorry, I misunderstood that you were asking about the blur originally

[MrRalgoman]

And I apologize, but could you go a bit more in depth about the Vector:ToScreen()? I am having a hard time understanding what you mean and what it does.

[editline]10th January 2017[/editline]

Here is the blur var

local blur = Material("pp/blurscreen")

[MysteryPancake]

You only need to use Vector:ToScreen() if you want to draw the HUD in 2D rather than having it 3D.

Vector:ToScreen() just gets a 3D vector (such as the 3D coordinates of a player's head for example) and returns 2D x and y coordinates of where this is on the local player's screen.

The reason you need to use this for 2D drawing is because any 2D drawing functions need x and y coordinates. For example, draw.SimpleText needs x and y coordinates of where to draw the text. You can't give it a 3D location to draw the text because it draws in 2D

Hopefully this makes a bit of sense, but I'm not good at explaining.

[editline]11th January 2017[/editline]

I tested the blur function and it works well in 2D, but in 3D it gets a bit tricky because since the cam function kind of distorts 2D stuff that gets drawn into being 3D it offsets the blur a bit from the screen

So are you saying it can't be done? Were you able to figure it out?

[editline]10th January 2017[/editline]

And how could I go about making a 2d hud that displays over a player?

When I plug that into my code, it doesn't draw anything at all.

Nevermind, added

Is there a way I could reduce the size of the box as a function of distance? So that the box remains the same size as players ran towards and away from eachother?

Here is why. I get it the position is off, I'm just figuring stuff out still.
