MTA:Dayz Onduty Script

Hello all!

I need help, i made by myself Onduty script for MTA:dayz, and i need some help whit it

When i write /aduty it shows me the arrow, but how can i get the TEXT at that Arrow

arrowTable = {}

addCommandHandler("aduty",

function(player)

local duty = getElementData(player, "duty") or 0

if duty == 0 then

if not isElement(arrowTable[player]) then

arrowTable[player] = createMarker(0, 0, 0, "arrow", 0.75, 255, 0, 0, 175)

end

attachElements(arrowTable[player], player, 0, 0, 2)

else

if isElement(arrowTable[player]) then

destroyElement(arrowTable[player])

arrowTable[player] = nil

end

end

end)

addEventHandler("onPlayerQuit", root,

function()

if isElement(arrowTable[player]) then

destroyElement(arrowTable[player])

arrowTable[player] = nil

end

end)

replace player with source

here

About second question all what you need is

  
triggerClientEvent 
getScreenFromWorldPosition() 
getCameraMatrix() 
getDistanceBetweenPoints3D() 
dxDrawText 
  

addEventHandler ( "onClientRender", root,

function ( )

if ( getDistanceBetweenPoints3D ( 0, 0, 3, getElementPosition ( localPlayer ) ) ) < 50 then

local coords = { getScreenFromWorldPosition ( 0, 0, 3 ) }

if coords[1] and coords[2] then

dxDrawText ( "Hello !", coords[1], coords[2], coords[1], coords[2], tocolor(255,255,255), 1, "default-bold" )

end

end

end )

like this?

not bad

local screenX, screenY = guiGetScreenSize () 
  
function leaderText(marker) 
    local xm,ym,zm = getElementPosition(marker) 
    local x,y = getScreenFromWorldPosition(xm,ym,zm+0.2) 
    local camX,camY,camZ = getCameraMatrix() 
        if (x and y and getDistanceBetweenPoints3D(camX, camY, camZ, xm,ym,zm) <= 20) then 
           dxDrawText ("Hello", x,y,x,y, tocolor (255,0, 0, 255) , ( screenX / 1440 ) * 2 , "default-bold" , "center" , "center" , false , true , false ) 
    end 
end 

Now try to use triggerClientEvent and post your code here and i will help you

Note :use LUA highlight syntax

[arrowTable = {}

addCommandHandler("aduty",

function(player)

local duty = getElementData(player, "duty") or 0

if duty == 0 then

if not isElement(arrowTable[player]) then

arrowTable[player] = createMarker(0, 0, 0, "arrow", 0.75, 255, 0, 0, 175)

addEventHandler("onClientRender",createText)

end

attachElements(arrowTable[player], player, 0, 0, 2)

else

if isElement(arrowTable[player]) then

destroyElement(arrowTable[player])

arrowTable[player] = nil

end

end

end)

addEventHandler("onPlayerQuit", root,

function()

if isElement(arrowTable[player]) then

destroyElement(arrowTable[player])

arrowTable[player] = nil

end

end)

local screenX, screenY = guiGetScreenSize ()

function leaderText(marker)

local xm,ym,zm = getElementPosition(marker)

local x,y = getScreenFromWorldPosition(xm,ym,zm+0.2)

local camX,camY,camZ = getCameraMatrix()

if (x and y and getDistanceBetweenPoints3D(camX, camY, camZ, xm,ym,zm) <= 20) then

dxDrawText ("Hello", x,y,x,y, tocolor (255,0, 0, 255) , ( screenX / 1440 ) * 2 , "default-bold" , "center" , "center" , false , true , false )

end

end

function greetingCommand ( playerSource, commandName )

triggerClientEvent ( playerSource, "onGreeting", playerSource, "Hello World!" )

end

addCommandHandler ( "greet", greetingCommand )

how to get LUA highlight syntex ?

Try to use this untested.
