Overhead name tag

[Charan]

i have a plugin which makes the nametag appear above the player and the own player and everyone too should be able to see it 

but it wont work heres the code

addEventHandler("onClientRender",getRootElement(),
function()
local px,py,pz,tx,ty,tz,dist
     px,py,pz = getCameraMatrix()
for k,v in ipairs(getElementsByType("player")) do
if (v~=getLocalPlayer()) then
           tx,ty,tz = getElementPosition(v)
           dist = math.sqrt((px-tx)^2 + (py-ty)^2 + (pz-tz)^2)
if dist < 30.0 then
if isLineOfSightClear(px,py,pz,tx,ty,tz,true,false,false,true,false,false,getLocalPlayer()) then
local sx,sy,sz = getPedBonePosition(v,5)
local x,y = getScreenFromWorldPosition(sx,sy,sz+0.3)
if x then
dxDrawText(getPlayerName(v),x,y,x,y,tocolor(150,50,0),0.85+(15-dist)*0.02,"bankgothic")
end
end
end
end
end
end
)addEventHandler("onClientRender",getRootElement(),
function()
local px,py,pz,tx,ty,tz,dist
	px,py,pz = getCameraMatrix()
for k,v in ipairs(getElementsByType("player")) do
		tx,ty,tz = getElementPosition(v)
		dist = math.sqrt((px-tx)^2 + (py-ty)^2 + (pz-tz)^2)
if dist < 30.0 then
if isLineOfSightClear(px,py,pz,tx,ty,tz,true,false,false,true,false,false,getLocalPlayer()) then
local sx,sy,sz = getPedBonePosition(v,5)
local x,y = getScreenFromWorldPosition(sx,sy,sz+0.3)
if x then
dxDrawText(getPlayerName(v),x,y,x,y,tocolor(150,50,0),0.85+(15-dist)*0.02,"bankgothic")
end
end
end
end
end
)

This is just another idea( not tested ) , feel free to use and edit it as you wish

--SERVER

addEventHandler( "onPlayerSpawn", getRootElement(), function ()
	triggerClientEvent( source, "player_onSpawn", source )
end )

--CLIENT

addEvent( "player_onSpawn", true )

local SHOW_DIST = 50
local TAG_RADIUS = createColSphere( 0, 0, 0, SHOW_DIST )

function initialiseNametags()
	attachElements( TAG_RADIUS, localPlayer, 0, 0, 0 )
	addEventHandler( "onClientRender", getRootElement(), renderNametags )
end 
addEventHandler( "player_onSpawn", getRootElement(), initialiseNametags )

local TAG_WIDTH, TAG_HEIGHT = 300, 50 

function renderNametags()
	local CAM_X, CAM_Y, CAM_Z = getCameraMatrix()
	local PLAYERS_IN_RADIUS = getElementsWithinColShape( TAG_RADIUS, "player" )
	
	for _, PLAYER in pairs ( PLAYERS_IN_RADIUS ) do 
		local PLAYER_X, PLAYER_Y, PLAYER_Z = getElementPosition( PLAYER )
		if isLineOfSightClear( PLAYER_X, PLAYER_Y, PLAYER_Z, CAM_X, CAM_Y, CAM_Z, true, false, false, true, false, false, localPlayer ) then
			local BONE_X, BONE_Y, BONE_Z = getPedBonePosition( PLAYER, 5 )
			local TAG_X, TAG_Y = getScreenFromWorldPosition( BONE_X, BONE_Y, BONE_Z + 0.3 )
			if ( TAG_X and TAG_Y ) then 
				dxDrawText( getPlayerName( PLAYER ), TAG_X - TAG_WITH / 2,  TAG_Y - TAG_HEIGHT / 2, TAG_X - TAG_WITH / 2 + TAG_WITH, TAG_Y - TAG_HEIGHT / 2 + TAG_HEIGHT, tocolor( 150, 50, 0 ), 1, "bankgothic" )
			end 
		end 
	end 
end 

One mistake i saw was at dxDrawText.For example, if you want to draw a text at coords 10, 10 with the height of 50 and width of 100 you need to write something like

dxDrawText( "text", 10, 10, 110, 60 ... ) ( the right and bottom must be coords, not the width and height )
