help Help with function "countPlayersInRange"

[Odonton]

Hoping that they are well, it turns out that I have a problem with my script, I want to make it work counting the players in an area and not the server to start the game. It gives me the global attempt to call countPlayersInRange (a nil value).

 

function chekin( player )--CHECK INICIO
   
    local alive =  countPlayersInRange(4754.6508789063, -2038.6687011719, 2.3671875, 40)
      
    if alive >= 8 and royale == false then -- mudar para 3
    outputChatBox ( "#FFFFFF[ROYALE]:#FF0000INICIANDO PARTIDA BATTLE ROYALE", root, 0, 255, 0, true )
    counter()
    elseif alive == 1 and royale == false then
    outputChatBox ("#FFFFFF[ROYALE]:#FF0000FALTA 7 JUGADORES", root, 255, 0, 0, true)
	elseif alive == 2 and royale == false then
    outputChatBox ("#FFFFFF[ROYALE]:#FF0000FALTA 6 JUGADORES", root, 255, 0, 0, true)
	elseif alive == 3 and royale == false then
    outputChatBox ("#FFFFFF[ROYALE]:#FF0000FALTA 5 JUGADOR", root, 255, 0, 0, true)
	elseif alive == 4 and royale == false then
    outputChatBox ("#FFFFFF[ROYALE]:#FF0000FALTA 4 JUGADORES", root, 255, 0, 0, true)
	elseif alive == 5 and royale == false then
    outputChatBox ("#FFFFFF[ROYALE]:#FF0000FALTA 3 JUGADOR", root, 255, 0, 0, true)
	elseif alive == 6 and royale == false then
    outputChatBox ("#FFFFFF[ROYALE]:#FF0000FALTA 2 JUGADORES", root, 255, 0, 0, true)
	elseif alive == 7 and royale == false then
    outputChatBox ("#FFFFFF[ROYALE]:#FF0000FALTA 1 JUGADOR", root, 255, 0, 0, true)
	end
	
end     

If you could explain why this error occurs and how to solve it would be very helpful, thanks!

It is simple. The countPlayersInRange function is not existing.

Wow, I found it on the MTA Wiki, I thought it was true, I apologize for the inconvenience. Do you know of a similar function?

[WorthlessCynomys]

Well you probably found it under the useful functions tab, so if you copy the function into your script then it'll work.

Otherwise, you can count players in a range with a colshape and a count (#)

I think it solved it by adding a content of an earlier window called "Function source", now it gives me the error that I can not compare it with a number because it is a boolean,: c, sorry for disturbing you

function countPlayersInRange(x,y,z, range)
  local tempCol = createColSphere(x,y,z,range)
  players = getElementsWithinColShape(tempCol, "player")
  destroyElement(tempCol)
  return #players
end

The last help I ask: c, it turns out that when using the same code for the players counter in the area, trying to show it as text in my HUD always shows the number 0 even though I am inside the area, with the code above if I showed all the players on the server. If you are too busy to respond, you will understand, apologize for the inconvenience.

It gives reputation points based on likes that comments have.

I haven't tested the function but it should work. Try to debug it. Output the elements of the player table with a for loop. Or maybe you can not "return #players" so you have to do sg like this

local count = #players
return count

Feel free to ask about this.

I really do not quite understand what I should do, when you refer to "Output the elements of the player with a for loop", apologize, I feel like an idiot asking things like this: /. By the way, we are doing a server type pubg c: if you want to tell us that such is sending you the ip by Internal? (there is an internal chat here, right?)

[WorthlessCynomys]

For PUBG i would use either dimensions or more servers. Not a players in range. You can count players in dimensions too.

I'll make my function on PC if you still need it and send the working one.

  local tempCol = createColSphere(x,y,z,range)
  players = getElementsWithinColShape(tempCol, "player")
  destroyElement(tempCol)
local numberof = 0
  for k,v in ipairs(players) do
numberof = numberof+1
end
return numberof
end

Wow, thanks, You are amazing, really thank you very much for everything, but I would feel badly demanding that you make me your codes. What if, now I have another problem, it results that we mapped a beautiful lobby, with landing strip, a crashed plane and so, but it works once, then disappears and I have to restart the resource "map" so that it is functional again, there some command to not restart, something like to fix the GM? :c

[WorthlessCynomys]

I would make those objects scripted. On client side. So i would create the objects in code on client side, so if any problem occours then you don't need to load a whole map.
