How to destroy marker with command??

[Mikhail]

I did this

 

function consoleCreateMarker ( thePlayer, commandName )
   if ( thePlayer ) then
      local x, y, z = getElementPosition ( thePlayer ) -- get the player's position
      -- create a cylindrical marker next to the player:
      local marker1 = createMarker ( x, y, z - 1, "cylinder", 1.5, 255, 255, 0, 170 )
      if ( theMarker ) then -- check if the marker was created successfully
         outputConsole ( "El marcador se ha creado correctamente", thePlayer )
      else
         outputConsole ( "Failed to create marker", thePlayer )
      end
   end
end
addCommandHandler ( "createma", consoleCreateMarker )

function marker11 ( marker11 )
    if isElementWithinMarker(thePlayer) then -- checking if player is in a marker 
        destroyElement ( marker )
    end 
end
addCommandHandler("deletema", marker11 )

 

(I'm new in scripting)

but this gives me this:

Bad argument @ 'isElementWithinMarker' [Expected element at argument 1, got nil]

      local marker1 = createMarker ( x, y, z - 1, "cylinder", 1.5, 255, 255, 0, 170 )
      if ( marker1 ) then -- check if the marker was created successfully
         outputConsole ( "El marcador se ha creado correctamente", thePlayer )
      else
         outputConsole ( "Failed to create marker", thePlayer )
      end
   end
end
addCommandHandler ( "createma", consoleCreateMarker )

function marker11 (thePlayer )
    if isElementWithinMarker(thePlayer, marker1) then -- checking if player is in a marker 
        destroyElement ( marker1)
    end 
end
addCommandHandler("deletema", marker11 )

change marker to a global variable.

[Dimos7]

function consoleCreateMarker ( thePlayer, commandName )
   if ( thePlayer ) then
      local x, y, z = getElementPosition ( thePlayer ) -- get the player's position
      -- create a cylindrical marker next to the player:
      marker1 = createMarker ( x, y, z - 1, "cylinder", 1.5, 255, 255, 0, 170 )
      if ( marker1 ) then -- check if the marker was created successfully
         outputConsole ( "El marcador se ha creado correctamente", thePlayer )
      else
         outputConsole ( "Failed to create marker", thePlayer )
      end
   end
end
addCommandHandler ( "createma", consoleCreateMarker )

function marker11 (thePlayer )
    if isElementWithinMarker(thePlayer) then -- checking if player is in a marker 
        destroyElement ( marker1)
    end 
end
addCommandHandler("deletema", marker11 )

Bad argument @ 'isElementWithinMarker' [Expected marker at argument 2, got none]

 

i think the entire destroy function is wrong... is another way to write it?

ok your script said it:         lua:20: unexpected symbol near 'ï' 

addCommandHandler("deletema", marker11 )

 

but I rewrote it to:

addCommandHandler ( "deletee", marker11)

and it worked!

 

but I have a query, could you explain in detail what change you in my script? because obviously you modify something, could you tell me my mistake and what do you modify? So I learn! although I am reading the wiki, we learn from mistakes, and better if you explain it to me ..

script

am just added the second argument in

isElementWithinMarker(thePlayer)

to make it like this

isElementWithinMarker(thePlayer,marker1)

@Master_MTA

 

oh. ok... im trying to put some more and in the chat dont shows...

function marker11 (thePlayer )
	if isElementWithinMarker(thePlayer,marker1) then -- checking if player is in a marker
	destroyElement ( marker1)
	else
	outputConsole ( "you should be in the marker to delete it", thePlayer)	
    end 
end
addCommandHandler ( "deletee", marker11)

and there are conflicts when I create more than 1 marker and I want to delete them 1 by 1 ... how would the command or the constant to delete all created?

 

this would end the script ..
