image above zombies head

[kewizzle]

how would i go about attaching an image above a zombies head to indicate the zombies health/strength 

 

addEvent("onZombieSpawned",true) 
addEventHandler("onZombieSpawned",root, 
function ( ) 
  setElementHealth ( source, math.random(25, 100 ) )
  if getElementHealth(source) >= 50 then
  end
end)

Use the dx drawing functions and use the event "onClientRender" to draw it for the client.

I tried this but it doesnt work.

client.lua

addEvent("Zomb_STFU",true) 
addEventHandler("Zomb_STFU",root, 
function ( zomb ) 
   triggerServerEvent ( "onZombieSpawned", zomb ) 
end) 

addEvent("drawLevelSt", true)
addEventHandler("drawLevelSt", root, function()
local x, y = getElementPosition(source)

function renderDisplay ( )
	local seconds = getTickCount() / 1000
	local angle = math.sin(seconds) * 80
	dxDrawImage ( x, y, 100, 240, 'arrow.png', angle, 0, -120 )
end


	function HandleTheRendering ( )
	addEventHandler("onClientRender", root, renderDisplay)
	end
	addEventHandler("onClientResourceStart",resourceRoot, HandleTheRendering)
end)

server.lua

addEvent("onZombieSpawned",true) 
addEventHandler("onZombieSpawned",root, 
function ( ) 
  setElementHealth ( source, math.random(25, 100 ) )
  if getElementHealth(source) >= 50 then
  triggerClientEvent ( "drawLevelSt", source, drawLevelStn, source  ) 
  end
end)

 

i found this

dxDrawImageOnElement

now to sure how it works ... just read it and i get errors.

I did this, but i dont know how to make it for only peds with health >= 50

local tag = dxCreateTexture("redDot.png")
 
addEventHandler("onClientPreRender", root,
	function()
		for k,v in ipairs(getElementsByType("ped")) do
		dxDrawImageOnElement(v,tag)
	end
end)

works now. 

local tag = dxCreateTexture("redDot.png")
 
addEvent("onClientPreRender", true)
addEventHandler("onClientPreRender", root,
	function()
		for k,v in ipairs(getElementsByType("ped")) do
		if getElementHealth(v) >= 50 then
		dxDrawImageOnElement(v,tag)
		end
	end
end)

Yeah sorry didn't mention the dxDrawImageOnElement function its really useful along with dxDrawTextOnElement which will draw text on an element so if you wanted to put text above a player too then you can use that
