This will always be 1. Your first eleven prints are impossible.

Ya sorry I was literally just removing the actual table lookup (which always returned false)

[QUOTE=Willox;45566523]net.WriteBit takes a boolean, not a number. When giving it a number your input will be turned in to a boolean and will always be treated as true due to numbers being truthy in Lua.[/QUOTE]
The function name is misleading :S (bool is a byte not a bit, I expected it to turn everything except the number zero into true)

The next gmod update introduces net.WriteBool and net.ReadBool, but until then you have to either implement them yourself or deal with the shittily named functions.

actually it makes it better:
net.WriteBit(ply.OwnedWeapons[i])
I was doing
net.WriteBit(ply.OwnedWeapons[i] and 1 or 0)

Hey, how would I modify a SWEP that is on the ground? For example changing it's material/colour

[residualgrub]

So I want to get all of the data that is in a DList but I am a bit confused on the out put of [b][url=http://wiki.garrysmod.com/?title=DListView.GetLines]DListView.GetLines [img]http://wiki.garrysmod.com/favicon.ico[/img][/url][/b].

It outputs something like this.

[img]http://puu.sh/aAUhB/26e9eae22d.png[/img]

I am not really sure what to do with this. Is there even a way to get all of the entered data from a dlist?

Is there a way to slow down player walk animation in gamemode?

[Ott]

[QUOTE=TheMostUpset;45567559]Is there a way to slow down player walk animation in gamemode?[/QUOTE]

Just lower their walkspeed. Source takes care of the animation.

[FluffyXVI]

Is there a hook for when a Derma Panel is closed?

[TheMostUpset]

[QUOTE=Ott;45567844]Just lower their walkspeed. Source takes care of the animation.[/QUOTE]

I need to keep my walkspeed, but slow down the animation

If that happened, their feet wouldn't sync up with the ground.

Just an example of how to view the contents of each line, tab separated.

for _, line in pairs( DListView:GetLines() ) do

    for _, column in pairs( line.Columns ) do

        Msg( column:GetText() .. "\t" )

    end

    print()

end

For my given DListView, it prints the contents out like this:

Each DListView_Line has a [B].Columns[/B] field that holds each panel that was created/added when DListView:AddLine() was called. So all you have to do is loop through those columns and call [B]:GetText()[/B] to retrieve the string value.

I just viewed the source for the DListView_Line to do this. You can find it here: [URL]https://github.com/garrynewman/garrysmod/blob/master/garrysmod/lua/vgui/dlistview_line.lua[/URL]

I hope this helps.
[B]
--Edit--[/B]
Looks like there is DListView_Line:GetColumnText( i ) as well, so you could change the 2nd for-loop to

for k, _ in pairs( self.Columns ) do 

    Msg( line:GetColumnText( k ) .. "\t" )

end

but it's not any more convenient than column:GetText().

Is it possible to get the size of the chat box?

[Mista Tea]

[QUOTE=tommy228;45570838]Is it possible to get the size of the chat box?[/QUOTE]

Not at the moment. You could try figuring out it's exact size at a specific resolution and then finding what it scales it by when changing resolution, but that's really lame.

I started a GitHub request for more chatbox functionality, and getting the width/height of the chatbox was one of the suggestions: [URL="https://github.com/Facepunch/garrysmod-requests/issues/266"]https://github.com/Facepunch/garrysmod-requests/issues/266

How do I get a position of a vgui element if I've placed it using Dock ? Element.GetPos seems to return 0

[Instant Mix]

This is happening with my swep and I have no idea why :

[ERROR] lua/weapons/wavebeam.lua:237: attempt to perform arithmetic on field 'FireMode' (a nil value)
  1. unknown - lua/weapons/wavebeam.lua:237

It's in blue so I'm assuming it's clientside lua, but i'm stopping anything being done on the client

Now, what i'm doing here is trying to change the weapon's firemode value when I press secondary fire; the code at fault is this :

function SWEP:SecondaryAttack()
    if CLIENT then return end
    if self.FireMode == 4 then
        self.FireMode = 1
    else
        self.FireMode = self.FireMode + 1
    end
    self:UpdateFireMode(2)
    print("Firemode Updated to "..self.FireMode)
    self:CallOnClient("UpdateFireMode",2)
    self:EmitSound( "weapons/armcannon/changebeam.wav" )
    self:SetNextSecondaryFire( CurTime() + 0.2)
end

I've got code at the beginning of the swep AND in Intialize setting firemode to 1.
What's the issue?

[Rubat]

if self.FireMode == 4 then
        self.FireMode = 1
    else
        self.FireMode = self.FireMode + 1
    end

This piece of code.

if nil == 4 then //self.FireMode is nil because you have not defined it anywhere
//blah
else
var = nil + 1 // nil + 1 throws an error.
end

Solution:

self.FireMode = self.FireMode or 1

in SWEP:Initialize.

Still spewing the exact same errors with that new code added in.

I have a table structured like a filepath for example this one:
[LUA]

tabl = {
someFolderNameHere = { someFolderNameHere11 = {someFileNameHere21 = "Hello"}, someFolderNameHere12 = {someFileNameHere23 = "Hello22"}},
someFolderNameHere2 = { someFolderNameHere211 = {someFolderNameHere21 = { someFileNameHereidk = "yay"}}},
etc...
}
[/LUA]

How would I go about adding the full thing to a DTree/DFileBrowser (note that the files aren't something I got from files.Find or similar so their default methods won't work)
(It also could be another nested list of anything else)

How do I get an NPC's health?

[QUOTE=IntenseBarney;45574382]How do I get an NPC's health?[/QUOTE]

NPC:Health(). Health is not networked to client for NPCs.

[QUOTE=Robotboy655;45574456]NPC:Health(). Health is not networked to client for NPCs.[/QUOTE]

Thanks, thought it would have been NPC:GetHealth() >.<

Yeah, some function names are counter intuitive. It should be GetHealth().

I mean it shows up and everything but the shapes are all squares and it conflicts with another mod. Even without that silly for i=300 line it has the same result.

[QUOTE=Robotboy655;45572564]Post the new code, with marking the erroring line.[/QUOTE]

offending code is still

function SWEP:SecondaryAttack()
    if !SERVER then return end
    if self.FireMode == 4 then
        self.FireMode = 1
    else
        self.FireMode = self.FireMode + 1 -- ERROR HERE M8 CAN YOU SEE ME AM I MARKED CLEAR

    self:CallOnClient("UpdateModeValues")
    self:EmitSound( "weapons/armcannon/changebeam.wav" )
    self:SetNextSecondaryFire( CurTime() + 0.2)
end

the changed code is :

function SWEP:Initialize()
    
    self.FireMode = self.Firemode or 1
    self:SetHoldType("shotgun")
    self.ChargePowerSound = CreateSound( self , "weapons/armcannon/powerbeam_charge.wav" )

    if SERVER then

        self:UpdateModeValues()
    end

    if CLIENT then
