How do I add an "Icon" on the screen?

[shadowsaints]

I want to add something like this:

[IMG]http://i1143.photobucket.com/albums/n627/santiago540/Nuevaimagendemapadebits_zps1fbc1787.jpg[/IMG]
(Paint level 9000)

How do I do that? I mean, I have the "triggers" but how do I make it so an transparent image appears in the middle-bottom part of the screen saying "Press Alt to do something" or how do I put some text saying that?

Thanks!

If you want to add text on the screen, try looking into the [URL="http://wiki.garrysmod.com/page/Category:surface"]surface library[/URL].

function PaintCustomHUD()
	draw.DrawText("Press ALT to do something", "Default", 40,40,Color(255,255,255,255),0)	
end
hook.Add("HUDPaint", "Whatever", PaintCustomHUD)

Put that in a lua file and send it to the client.

Yeah, the thing is that I want to do that when a trace hits something, how do I do that?

		function Thing()
		for id,ply in pairs ( player.GetAll( ) ) do
			tracedata={}
				tracedata.start = ply:EyePos()
				tracedata.endpos = ply:EyePos()+(ply:GetAimVector()*64)
				tracedata.filter = ply
				local trace = util.TraceLine(tracedata)
				if trace.Hit then
---here should be the press alt to do something thing--

You'd have to hook the entire function into a HUDPaint hook like so:
[lua]
ply = LocalPlayer()
hook.Add( "HUDPaint", "DrawMessage", function()

tracedata={}
tracedata.start = ply:EyePos()
tracedata.endpos = ply:EyePos()+(ply:GetAimVector()*64)
tracedata.filter = ply
local trace = util.TraceLine(tracedata)
if trace.Hit then
draw.DrawText( "Press ALT to peek", "Default", 40, 40, Color( 255, 255, 255 ) )
end

end )
[/lua]
This would only be needed clientside, since the surface library and the HUDPaint hook only work clientside.

To draw an icon use this:

Where _mat is a Material( ) defined outside of the HUDPaint, and _x, _y are the location, and _w, _h are the width and height of the material.
[lua]surface.SetMaterial( _mat );
surface.SetDrawColor( Color( 255, 255, 255, 255 ) );
surface.DrawTexturedRect( _x, _y, _w, _h );[/lua]

Thank you!

Is there any way to change the size?

You'd have to make your own font using [url=http://wiki.garrysmod.com/page/surface/CreateFont]surface.CreateFont[/url]
