Problem with destroyelement

[Unique23]

Hello Everyone,

I am trying to make a barrier system for the team.

Here is the code,

  
local barrier = {} 
  
function createBarrier ( thePlayer ) 
    if ( getTeamName(getPlayerTeam(thePlayer)) == "Unique" ) then   
         local nX, nY, nZ = getElementPosition(thePlayer) 
        local nX2, nY2 = 0, 0 
        local nZ2 = getPedRotation(thePlayer) 
        local barrier = createObject(3578, nX, nY, nZ - 0.2, 0, 0, nZ2) 
        setElementPosition(thePlayer, nX, nY, nZ + 1) 
        end 
    end     
addCommandHandler ("b", createBarrier) 
  

There is no problem about creating a barrier.It works fine.But the problem I have is, when I do /r , I want object to remove itself.

  
function removeBarrier ( thePlayer ) 
 if isElement(barrier) then 
    destroyElement(barrier) 
    barrier = nil 
  end 
end     
  
addCommandHandler ("r", removeBarrier,thePlayer) 
addEventHandler("onPlayerQuit", root, removeBarrier) 
  

This didn't work.

Plus: When I spam /r , script puts a lot of yellow barriers but I want script to remove last barrier when I want to put new one.

Try this:

local barrier = {} 
  
function createBarrier ( thePlayer ) 
    if ( getTeamName(getPlayerTeam(thePlayer)) == "Unique" ) then   
        local nX, nY, nZ = getElementPosition(thePlayer) 
        local nX2, nY2, nZ2 = getElementRotation(thePlayer) 
        barrier[thePlayer] = createObject(3578, nX, nY, nZ - 0.2, 0, 0, nZ2) 
        setElementPosition(thePlayer, nX, nY, nZ + 1) 
        end 
    end     
addCommandHandler ("b", createBarrier) 
  
function removeBarrier ( thePlayer ) 
 if isElement(barrier[thePlayer]) then 
    destroyElement(barrier[thePlayer]) 
    barrier[thePlayer] = nil 
  end 
end 
addCommandHandler ("r", removeBarrier) 
  
addEventHandler("onPlayerQuit", root,  
function () 
    if isElement(barrier[source]) then 
        destroyElement(barrier[source]) 
        barrier[source] = nil 
  end 
end)

local barrier = {} 
  
function createBarrier ( thePlayer ) 
    if ( getTeamName(getPlayerTeam(thePlayer)) == "Unique" ) then   
         local nX, nY, nZ = getElementPosition(thePlayer) 
        local nX2, nY2 = 0, 0 
        local nZ2 = getPedRotation(thePlayer) 
        local barrier[thePlayer] = createObject(3578, nX, nY, nZ - 0.2, 0, 0, nZ2) 
        setElementPosition(thePlayer, nX, nY, nZ + 1) 
        end 
    end     
addCommandHandler ("b", createBarrier) 
  
function removeBarrier ( thePlayer ) 
 if isElement(barrier[thePlayer]) then 
    destroyElement(barrier[thePlayer]) 
    barrier[thePlayer] = nil 
  end 
end 
addCommandHandler ("r", removeBarrier,thePlayer) 
  
addEventHandler("onPlayerQuit", root, 
function () 
    if isElement(barrier[source]) then 
        destroyElement(barrier[source]) 
        barrier[source] = nil 
  end 
end) 
  

It didn't work and gave an error at line 8: unexpected symbol near [

But I removed [thePlayer] at that line it worked then tried to do /r , didn't work.

And as i said i don't want spam like this screnshot: http://i.imgur.com/T7axIsd.jpg

local barrier = {} 
  
function createBarrier(thePlayer) 
    local team = getPlayerTeam(thePlayer) 
    if (team and getTeamName(team) == "Unique") and not isElement(barrier[thePlayer]) then  
        local nX, nY, nZ = getElementPosition(thePlayer) 
        local nX2, nY2 = 0, 0 
        local nZ2 = getPedRotation(thePlayer) 
        barrier[thePlayer] = createObject(3578, nX, nY, nZ - 0.2, 0, 0, nZ2) 
        setElementPosition(thePlayer, nX, nY, nZ + 1)
