[QUESTION] About a name tag

nyxudf · March 20, 2022

Hello everyone, I have a question about this script that I found in the community. It doesn't have any errors on startup, I just want to know how I could hide the local player's tag but keep others visible.

Client side:

myfont = "default-bold"
nametags_Root = getRootElement()
nametags_ResRoot = getResourceRootElement(getThisResource())
nametags_Players = getElementsByType('player')
nametags_Me = getLocalPlayer()

nametag = {}
local nametags = {}
local sWidth,sHeight = guiGetScreenSize()
local Nametags_Hide = false
local Nametags_Scale = 0.36
local Nametags_Alpha_Distance = 30 
local Nametags_Distance = 40
local Nametags_Alpha = 255
local Nametags_Text_Bar_Space = 1
local Nametags_Width = 50
local Nametags_Height = 20
local Nametags_Size = 0.45
local Nametags_Outline_Thickness = 1.2
local Nametags_Alpha_Diff = Nametags_Distance - Nametags_Alpha_Distance
Nametags_Scale = 1/Nametags_Scale * 800 / sHeight 

local maxScaleCurve = { {0, 0}, {3, 3}, {13, 5} }
local textScaleCurve = { {0, 0.8}, {0.8, 1.2}, {99, 99} }
local textAlphaCurve = { {0, 0}, {25, 100}, {120, 190}, {255, 190} }

function nametags.Create ( player )
	nametags[player] = true
end

function nametags.Destroy ( player )
	nametags[player] = nil
end

addEventHandler ( "onClientRender", nametags_Root,
	function()
		if getElementData(getLocalPlayer(), "state.hud") == "disabled" then return end
		for i,player in ipairs(nametags_Players) do
			if isElement(player) then
				setPlayerNametagShowing ( player, false )
				if not nametags[player] then
					nametags.Create ( player )
				end
			end
		end
		if Nametags_Hide then
			return
		end
		local x,y,z = getCameraMatrix()
		for player in pairs(nametags) do 
			while true do
				if not isElement(player) then break end
				if getElementDimension(player) ~= getElementDimension(nametags_Me) then break end

				local bx, by, bz = getPedBonePosition( player, 5 )

				local playerDistance = getDistanceBetweenPoints3D ( x,y,z,px,py,pz )
