The problem is bad syntax. You can't have 2 juxtaposed colon calls without function arguments between them (eg, x:y():z() ). Following on from your previous post in another thread, you might want something like this:

[lua]
ent.OldAngles = ent:GetAngles( )
ent:SetAngles( ent:GetNetworkedAngle( "Rotation" ))
[/lua]

Got some more questions :( First, I have a UI that's mostly panels that are painted boxes. Whenever I click outside of them, they change color. How can I prevent this?

Additionally, in that same UI, DModelPanels aren't showing up, and I basically c+pd it from the GMod Wiki. How come?

Thanks in advance!

the error I get:

Could I use loops to make a menu like [url=http://puu.sh/j9Xn1/3cfe92fedb.jpg]this[/url]?

I'm thinking integers and tables. Or is there no other way than 135 lines of code?
And should I bother even trying to make a loop out of it?

[B]EDIT:[/B]
Couldn't really find any documentation of loops on the new wiki, and unsure how much of the old one works.

I need a hint on how to proceed with re-sorting things on a table.
I have this nice table where each element has three keys, and there is a variable number of elements.

{"1":{"url":"https://www.youtube.com/watch?v=ZqMqTB7RSjo","vidnumber":0, "vidtitle":"Cake recipe #1"},"2":{"url":"https://www.youtube.com/watch?v=2SbZYJwqnOo","vidnumber":1,"vidtitle":"Cake recipe #2"},"3":{"url":"https://www.youtube.com/watch?v=6Zx7dm0Y1sk","vidnumber":2,"vidtitle":"Cake recipe #3"},"4":{"url":"https://www.youtube.com/watch?v=d1PbHGtQaaE","vidnumber":3,"vidtitle":"Cake recipe #4"},..............}

I want to move (via functions, unless there's something better with Derma) Cake recipe #3 to its left, so the final result would be recipe #1, recipe #3, recipe #2, recipe #4. I can't think of how to do it though, should I move the element being moved to a temporary table and make each video at its left have vidnumber+1, should I ditch vidnumber and change the element's key (if so, how)...?

[Coment]

[QUOTE=Shenesis;48276077]Something like this?

[lua]
local tbl = {
[1] = "1",
[2] = "2",
[3] = "3",
[4] = "4",
}

local keytomove = 3

table.insert( tbl, 2, tbl[ keytomove ] )
tbl[ keytomove + 1 ] = nil

for _, v in pairs ( tbl ) do
print(v)
end

-- prints 1, 3, 2, 4

That works perfectly! Thanks a ton.
(I also want it to go in the other order, but I understand enough to switch that by myself)

Hey guys, real quick, I'm creating buttons from a table with a for loop:

Table:

MS_Categories = {
    models = {
        Name = "Player Models 2.0",
        Guerilla = {
            Name = "Guerilla",
            Price = 1000,
            Model = 'models/player/guerilla.mdl'
        }
    },
    
    hats = {
        Name = "Hats/Heads 2.0",
        Melon = {
            Name = "Melon",
            Price = 1000,
            Model = 'models/props_junk/watermelon01.mdl'
        }
    }
}

Loop:

   for k, v in pairs( MS_Categories ) do
       local categorybutton = vgui.Create("DButton", dsidebar)
       local bw, bh = 75, 75
       categorybutton:Dock( TOP )
       categorybutton:SetSize(bw, bh)
       categorybutton:SetPos(ScrW() - bw, 0)
       categorybutton:SetText( MS_Categories.k.Name ) -- Trouble line
       categorybutton:SetFont( "MS_Button" )
   end

How could I make MS_Categories.k.Name actually return the value I want?

Indexing a table with . means that the key is a string. In your case it's a number so it fails.
EG:
[lua]
local tab = {["hey"] = "man", [15] = "yo"}
tab.hey == "man" -- true
tab.15 == "yo" -- syntax error
tab[15] == "yo" -- true
[/lua]

I'm working on a small test lua where you have to answer a question when you join the server. I've got this so far:

function GM:PlayerInitialSpawn( ply )

if SERVER then
	AddCSLuaFile("server_question.lua")
end

if CLIENT then
local frame = vgui.Create( "Answer this!?" )
frame:SetSize( 400, 200 )
frame:Center()
frame:MakePopup()

local DLabel = vgui.Create( "DLabel", Panel )
DLabel:SetPos( 40, 40 )
DLabel:SetText( question )

local TextEntry = vgui.Create( "DTextEntry", frame )
TextEntry:SetPos( 40, 60 )
TextEntry:SetSize( 75, 85 )
TextEntry:SetText( "Enter Answer Here!" )
TextEntry.OnEnter = function( self )
	if self:GetValue() == answer then
		frame:Close()
		end
	else
		TextEntry:SetText("Incorrect!")
		end
	end
end

and then the questions/answers in the seperate Lua like this:

function PickQuestion()

local q = math.random( 1, 100)

if q = 1 then
	local question = "blah blah?"
	local answer = "blah"
elseif q = 2 then
	local question = "random text"
	local answer = "just testing this"
else
	local question = "blah blah"
	local answer = "blah"


	end
end

(obviously I'm gonna add a lot more questions than that)

So I'm gonna ask a probably noob question: what's the most efficient way of getting the local variables from one function to the other? Or should I set this up way differently?

EDIT: I think I'm being dumb and am just missing this:

return question, answer

[/QUOTE]

One problem is that you're defining the question/answer vars as local variables within the if-then statement, meaning they can't leave it.

As soon as you end that if statement, your question/answer vars go poof.

function PickQuestion()

local q = math.random( 1, 100)
local question, answer

if q = 1 then
	question = "blah blah?"
	answer = "blah"
elseif q = 2 then
	question = "random text"
	answer = "just testing this"
else
	question = "blah blah"
	answer = "blah"
end

return question, answer
end

You'll also have to call the function at the start of your

if CLIENT then

bit and append something like

if CLIENT then
local question, answer = PickQuestion()

to it so that you can actually roll for your Q/A.

also move that

if SERVER then
	AddCSLuaFile("server_question.lua")
end

to the outside of the PlayerInitialSpawn function without the

if SERVER then
end

bit.

I'm creating a client side panel with buttons that spawn an Npc. Everything seems setup correctly and there are no errors in console. Yet nothing happens when I try to spawn the Novnpc via the button. Ideas?

[Sugar Tits]

My server has some issues when a player changes jobs randomly. The server can stay up anywhere from 4 hours - 28 hours until a random player changes jobs to anything. I have been looking in every addon for functions that are called when the player changes jobs / teams such as PlayerSpawn, OnPlayerChangedTeam, PlayerCanJoinTeam, PlayerLoadout. What else should I look for? I already tried removing 80% of the addons and the issue still persist (I also tried a blank SQLite and MySQL DB with no luck). Server gets a segmentation fault when the player fully picks up their weapons.

I don't know anything about the Mesh library, but I know that for IMesh objects, what you need to do is [i]render a model first[/i] with Entity:DrawModel() or something so that its lighting information carries over to the mesh:

function ENT:Draw()

	//Render the entity's model so that its lighting gets applied to the mesh,
	//but use a completely invisible texture so it doesn't actually show up
	render.ModelMaterialOverride( Material("some_invisible_texture_vmt_that_you_made") )
	self:DrawModel()
	render.ModelMaterialOverride()


	//Now render the imesh
	render.SetMaterial(mat)

	local matrix = Matrix()
	matrix:SetTranslation(self:GetPos())
	matrix:SetAngles(self:GetAngles())

	cam.PushModelMatrix( matrix )
		self.MeshObject:Draw()
	cam.PopModelMatrix()

end

Maybe you can adapt something like that to however you're using the mesh library.

I don't want to make this post extra lengthy by posting a video here so I'll link the video: [url]https://youtu.be/XH6QIdAeARE[/url] So, I want to achieve a recoil system as seen at 4:02 in the video. You'll notice that the player's view is pushed up then pushed slowly back down(I don't want to use ViewPunch for this). Could I achieve this by using math.Clamp, CurTime(), and self.Owner:EyeAngles()? Thanks. Link to the original thread:

I was considering using IMesh, but at first glance it felt more restricted than Mesh.

This is what I've got right now in the ENT:Draw() function. I'll see if that invisible bit makes a difference though!
[lua]function ENT:Draw()

self:DrawModel()

local ang = Angle()
local pos = self:GetPos()
ang = self:LocalToWorldAngles(ang)

drawMeshes(pos, ang)

IMesh should be faster than mesh.* stuff because with mesh.* you need to call ton of functions in a draw hook instead of one. And I don't believe IMesh is more restricted, they have same capabilities.

Also should PickQuestion() be localized? I've tried it both ways and neither work

Does running hook.Call() on a server-only block of call only run that hook on the server and doesn't fire on the client?
