Creating Custom Tags (chat appearing twice)

Garry's Mod coding
#1

Hey guys, so I am making a chat tags addon for my TTT server, but I’m having this error when I type in the chat.

http://puu.sh/wNJ7e/c0abf14d28.jpg

I’m assuming this has to do with the sandbox gamemode but I don’t know how to override the default chat. Any help would be appreciated.

Code:

-- Clientside File

local tag = {}
local ply = LocalPlayer()

local color = {} 
color.pl = Color(0, 255, 0, 255)
color.tag = Color(255, 0, 0, 255)

function OpenMenu() 

	local frame = vgui.Create("DFrame")

	frame.width = 390
	frame.height = 390

	frame:SetSize(frame.width, frame.height)
	frame:SetPos(400, 500)
	frame:MakePopup()
	frame:SetTitle("Boujee TTT Custom Tags")
	frame:AlignLeft(20)
	
	-- Set Tag button
	local button1 = vgui.Create("DButton", frame)
	
	button1.width = 110
	button1.height = 25

	local tagEntry = vgui.Create("DTextEntry", frame)
	
	tagEntry.x = button1.x + 134
	tagEntry.y = button1.y + 2
	
	tagEntry:SetPos(tagEntry.x, tagEntry.y)
	tagEntry:SetSize(180, 20)
	tagEntry:SetUpdateOnType(true)
	tagEntry:SetText("Enter Custom Tag")
	
	tagEntry.OnValueChange = function(self)
		tagEntry.value = self:GetValue()
	end
	
	-- Tag Color Mixer
	local colorPicker1 = vgui.Create("DColorMixer", frame)
	
	colorPicker1.x = button2.x + 135
	colorPicker1.y = button2.y - 30
	
	colorPicker1:SetPos(colorPicker1.x, colorPicker1.y)

		else
			chat.AddText(Color(255,0,0,255), "[Tags] Error: ", color_white, "You must have a tag enabled to set it's color!")
		end
	end

	-- Name Color button pressed
	button3.DoClick = function()
		tag.CustomNameColor = colorPicker2:GetColor()
		chat.AddText(Color(255,0,0,255), "[Tags] ", color_white, "Name color changed: ", tag.CustomNameColor, ply:Nick(), color_white, "." )
	end
	
end

// - Open the menu when player types command - //

hook.Add("OnPlayerChat", "PlayerChat", function( ply, text ) 
	
	if text == "!tags" then OpenMenu() end
	
	if tag.Enabled == true then
		chat.AddText(tag.CustomColor, "[", tag.CustomTag, "]", " ", tag.CustomNameColor, ply:Nick(), ": ", color_white, text)
	end
	
end )

This is one of the first things I have created in lua, so I would also appreciate any tips on how I could improve my code!

#2

If you put


return true

at the end of your OnPlayerChat hook, it’ll suppress the original message.

GM:OnPlayerChat

#3

Add “return true” to the end of your OnPlayerChat hook and it should work as intended.

Edit: a-cookie beat me

#4

Thanks both of you. I should have read the ENTIRE wiki page.

Okay new problem, on my server when I open the derma, it opens on every player screen. How would I open this only to the local player who types !tags?

I tried changing OpenMenu() to ply:OpenMenu() and I got errors.


 

[ERROR] lua/autorun/client/cl_tags.lua:137: attempt to call method 'OpenMenu' (a nil value)
  1. fn - lua/autorun/client/cl_tags.lua:137
   2. unknown - addons/ulib/lua/ulib/shared/hook.lua:109
#5

If you want the method to work like that, you’ll have to grab the Player metatable with

FindMetaTable and add the function to that.

#6

If you want to create a function that will be called on a player.
Replace
[LUA]function someFunctionName() end[/LUA]
With
[LUA]pMeta = FindMetaTable(“Player”)
function pMeta:someFunctionName() end [/LUA]

#7

I changed the hook to this:



hook.Add("OnPlayerChat", "PlayerChat", function( ply, text ) 
	
	if text == "!tags" then pMeta:MenuOpen() end
	
	if tag.Enabled == true then
		chat.AddText(tag.CustomColor, "[", tag.CustomTag, "]", " ", tag.CustomNameColor, ply:Nick(), ": ", color_white, text)
		return true
	else
		chat.AddText(color_white, ply:Nick(), ": ", text)
		return true
	end
end )

and the function opens like this:



local pMeta = FindMetaTable("Player")
function pMeta:MenuOpen()

But it still opens on every player’s screen when called.

#8

check if ply == localplayer

#9

At the top of the code I put ply = LocalPlayer()

[editline]19th July 2017[/editline]

#10

no i said, check if the player that is provided in the onplayerchat hook is equal to you, the localplayer, if it is then you call the function

#11

you’ll want to put your check on this line along with your current check


if text == "!tags" then pMeta:MenuOpen() end
#12

Okay thank you.

Currently, when I set my tag, that tag appears next to everyone’s name when they type. Basically the tag is only showing up for the local player. What would I do to make the tag unique to the player and for everyone to see?

#13

Network it using the net libary
Library: http://wiki.garrysmod.com/page/Category:net
Use examples: http://wiki.garrysmod.com/page/Net_Library_Usage

#14

Okay, so I have got the server to receive the tag info when the player clicks the set tag button.



AddCSLuaFile("cl_tags.lua")

util.AddNetworkString("button1Pressed")
util.AddNetworkString("button2Pressed")

net.Receive("button1Pressed", function(ply) 
	tag = net.ReadString()
	print("Server received set tag: " .. tag)
end )

net.Receive("button2Pressed", function(ply) 
	tagColor = net.ReadColor()
	print("Server got tag color: " .. tagColor)
end )

hook.Add("PlayerSay", "CheckAndSendTag", function() 
	if tag then
		util.AddNetworkString("SendServerTagInfo")
		
		net.Start("SendServerTagInfo")
			net.WriteString(tag)
		net.Broadcast()
	end
	
	if tagColor then
		util.AddNetworkString("SendServerColorInfo")
		
		net.Start("SendServerColorInfo")
			net.WriteColor(tagColor)
		net.Broadcast()
	end
end )

(Ignore tag color code, I am only worried about the actual tag for now)
Now I am not sure what to have the client do when it receives the message from the server. Could I have to check for the server tag info in the OnPlayerChat hook?

Here is the updated code:

I am trying to make the tags unique and seen by all players.

#15

Create a table with all the players tags in and then use the player as the key and the data as value.
You should also do this on the server, so when a new player joins they can be sent the tags data so they are always correct.
One last thing is don’t forget to remove the old players tags when they leave to stop memory being eaten.
