Remove works properly, the problem is that dframe still tries to use those buttons, resulting in errors.

I seem to have an issue with net.WriteString (or perhaps net.ReadString, I'm not sure). When I attempt to write a string containing special characters (that look like NUL, DLE, SOH, EOT and stuff like that), some of them appear to be discarded/removed. To see what I mean, try using file.Read to read any kind of image file (that contains those kind of special characters), then use net.WriteString on a shorter version of it, then check the length of the string before and after you send it.

use net.WriteData

[MysteryPancake]

When it says 'the length of the binary data to be sent, in bytes', how am I meant to find the byte size of a string? Or is it just the string's length? Probably obvious, but I don't know.
Edit: Ah, it's the string's length. THANKS SO MUCH, MAN!

I have another issue- how can I get this DScrollPanel's scrolling bar to not show when it's children get removed?

concommand.Add( 'ScrollTest', function()

	local base = vgui.Create( 'DFrame' )
	base:SetSize( 200, 200 )
	base:Center()
	base:MakePopup()
	
	local scroll = vgui.Create( 'DScrollPanel', base )
	scroll:Dock( FILL )
	
	local tbl = {}
	
	for i = 1, 3 do
		tbl[ #tbl+1 ] = vgui.Create( 'DPanel', scroll )
		tbl[ #tbl ]:Dock( TOP )
		tbl[ #tbl ]:SetSize( 0, 70 )
	end
	
	timer.Simple( 1, function()
		for k, v in pairs( tbl ) do v:Remove() tbl[k] = nil end
	end )
	
	timer.Simple( 2, function()
		scroll:InvalidateLayout() -- Doesn't work
	end )

end )

[QUOTE=MPan1;48921396]I have another issue- how can I get this DScrollPanel's scrolling bar to not show when it's children get removed?[/QUOTE]

Can't you just hook to the panels think function and set EnableVerticalScrollbar to false if #tbl = 0?

[MysteryPancake]

[QUOTE=DeathWard;48921432]Hook the think function to setting EnableVerticalScrollbar to false if #tbl = 0[/QUOTE]

EnableVerticalScrollbar throws an error for me, and even doing self.VBar:SetEnabled(false) doesn't work.

[editline]17th October 2015[/editline]

Jesus, to get it to do anything I have to do

function scroll:Think()
	if #tbl == 0 then
		self.pnlCanvas:SetVisible( false )
		self.VBar:SetVisible( false )
		for k, v in pairs( self.VBar:GetChildren() ) do v:SetVisible( false ) end
		else
		self.pnlCanvas:SetVisible( true )
		self.VBar:SetVisible( true )
		for k, v in pairs( self.VBar:GetChildren() ) do v:SetVisible( true ) end
	end
end

Surely there's a better way?

[zamboni]

concommand.Add( 'ScrollTest', function()


    local base = vgui.Create( 'DFrame' )
    base:SetSize( 200, 200 )
    base:Center()
    base:MakePopup()
    
    local scroll = vgui.Create( 'DScrollPanel', base )
    scroll:Dock( FILL )
    
    local tbl = {}
    
    for i = 1, 3 do
        tbl[ #tbl+1 ] = vgui.Create( 'DPanel', scroll )
        tbl[ #tbl ]:Dock( TOP )
        tbl[ #tbl ]:SetSize( 0, 70 )
    end
    
    timer.Simple( 1, function()
        for k, v in pairs( tbl ) do v:Remove() tbl[k] = nil end
    end )
    
    timer.Simple( 1.1, function()
        scroll.VBar:SetVisible(false)
    end )


end )

This works for me.

[MysteryPancake]

Wow, works for me as well... thanks!

for k,v in pairs( ents.FindByClass("gmod_dynamite") ) do
	v:Explode( delay, player )
end

Player does not have to be defined aswell, delay does though.

That code runs perfectly fine on a single player game for me, it explodes all of the dynamite.

I am trying to create a functional weapon flashlight attachment for [url=http://steamcommunity.com/sharedfiles/filedetails/?id=349050451]Customizable Weaponry 2[/url].
what I do, is use ents.Create to create an env_projectedtexture. my problem with this, is that when the code I use is run, the following error is printed to the console:

I made the changes live. I'll try restarting and see if that makes a difference.

It's because ents.Create is a serversided function.

How can I add new buttons to the "C"-Context menu and the Right-Click Context menu? Is there a hook to use or a list to add to?

Is there any way to Add/Set proxies on IMaterial ? Or atleast override already loaded material ?

Anyone know what's wrong with this code?

function DrawEyeLines()
	local players = player.GetAll() -- Get all player entities.
	if not tobool(DrawEyeTraces:GetInt()) then return end -- If this is false, do not continue.
	local vm = players:EyePos() -- Get all players eye position. (I think?)
	local t = util.GetPlayerTrace(players) -- Starts trace at targets viewpos and goes along a set line.
	local tr = util.TraceLine(t) -- Does a "trace" with the playertrace data. Returns tr.HitPos where it touches something(?)
	cam.Start3D(EyePos(), EyeAngles())
	--Draw the laser beam.
	render.SetMaterial(Material("sprites/bluelaser1"))
	render.DrawBeam(vm.Pos, tr.HitPos, 2, 0, 12.5, Color(255, 0, 0, 255)) -- Draw a beam from the target's eyes to whatever they are aiming at.
	--Draw a laser dot at the end of the beam.
	local Size = math.random() * 1.35 --That .65 makes all the difference, Im sure.
	render.SetMaterial(Material("Sprites/light_glow02_add_noz"))
	render.DrawQuadEasy(tr.HitPos, (EyePos() - tr.HitPos):GetNormal(), Size, Size, Color(255,0,0,255), 0)
	cam.End3D()
end
hook.Add("PostDrawTranslucentRenderables", "THISISUNIQUE", DrawEyeLines)

[I]Sorry for the stupid amount of comments, I kept forgetting what each bit did.[/I] :downs:
Im trying to draw a beam from every players eye position to wherever they are looking, but I keep getting the following error:

lookinglines.lua:51: attempt to call method 'EyePos' (a nil value)
lookinglines.lua:51

Ive been up all night trying to figure this out and im a bit stumped.
Any help would be much appreciated =)

[Rubat]

Entity:EyePos is a function that can be used on an entity.

You used it on a table on Entities, a table doesn't have a function/method named EyePos.

 Get all players eye position. (I think?)

How do you expect that to work?

[deinemudda32]

Can ent:Ignite() ignite the entity forever?

I don't know, Im a bit confused.
How would you suggest going about what I'm trying to do?

Thank you.

[Rubat]

You need to for-loop through each player and call the drawing code for each player.

[Deathbypwnage]

[QUOTE=Robotboy655;48929999]You need to for-loop through each player and call the drawing code for each player.[/QUOTE]

So, something like this?

function DrawEyeLines()
	for k, v in pairs( player.GetAll() ) do
		if not tobool(DrawEyeTraces:GetInt()) then return end -- If this is false, do not continue.
		local vm = v:EyePos()
		local t = util.GetPlayerTrace(v) -- Starts trace at targets viewpos and goes along a set line.
		local tr = util.TraceLine(t) -- Does a "trace" with the playertrace data. Returns tr.HitPos where it touches something(?)
		cam.Start3D(EyePos(), EyeAngles())
		//Draw the laser beam.
		render.SetMaterial(Material("sprites/bluelaser1"))
		render.DrawBeam(EyePos(), tr.HitPos, 2, 0, 12.5, Color(255, 0, 0, 255))
		//Draw a laser dot at the end of the beam.
		local Size = math.random() * 1.35 //That .65 makes all the difference
		render.SetMaterial(Material("Sprites/light_glow02_add_noz"))
		render.DrawQuadEasy(tr.HitPos, (EyePos() - tr.HitPos):GetNormal(), Size, Size, Color(255,0,0,255), 0)
		cam.End3D()
	end
end
hook.Add("PostDrawTranslucentRenderables", "THISISUNIQUE", DrawEyeLines)

Sorry to keep bugging you. I really have no clue about this.

[Rubat]

Yeah, but you do not need the cam.Start3D() stuff, PostDrawTranslucentRenderables hook is already has 3D rendering context.

Hmm. This code doesn't seem to do anything, can you see what I did wrong?

function DrawEyeLines()
	for k, v in pairs( player.GetAll() ) do
		if not tobool(DrawEyeTraces:GetInt()) then return end
		local vm = v:EyePos()
		local t = util.GetPlayerTrace(v)
		local tr = util.TraceLine(t)
		render.SetMaterial(Material("sprites/bluelaser1"))
		render.DrawBeam(EyePos(), tr.HitPos, 2, 0, 12.5, Color(255, 0, 0, 255))
		local Size = math.random() * 1.35
		render.SetMaterial(Material("Sprites/light_glow02_add_noz"))
		render.DrawQuadEasy(tr.HitPos, (EyePos() - tr.HitPos):GetNormal(), Size, Size, Color(255,0,0,255), 0)
	end
end
hook.Add("PostDrawTranslucentRenderables", "THISISUNIQUE", DrawEyeLines)

Also, I can't seem to rate posts on here, is that because I haven't been a member long enough?

All of those show up in console when the script is run.
I changed the line material to make sure it wasn't just drawing an invisible line, but even with something I know works it still isn't showing.

This is what I was originally working from:
[url]https://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/indexdd58.html[/url]
I guess it doesn't work anymore?
