Syntax

table getElementsByType ( string type )

Required Arguments

  • type: The type of element you want a list of. This can be any one of the following things MTA is programmed to understand:
    • "player": A player connected to the server
    • "vehicle":: A vehicle
    • "object": An object
    • "pickup": A pickup
    • "marker": A marker

    • "team": A team
    • "spawnpoint": A spawnpoint
    • "remoteclient": A remote client connected to the server
    • "console": The server Console
    • "unknown": Unknown element type

Returns

Returns a table containing all the elements of the specified type. Returns an empty table if there are no elements of the specified type. Returns false if the string specified is invalid (or not a string).

Example

This example retrieves a table of the players in the server, and checks whether or not each one is in a vehicle: 

local players = getElementsByType ( "player" ) -- get a table of all the players in the server
for theKey,thePlayer in players do -- use a generic for loop to step through each player
   if ( isPlayerInVehicle ( thePlayer ) ) then -- if the player is in a vehicle, announce it
      outputChatBox ( getClientName ( thePlayer ) .. " is in a vehicle" )
   else -- if the player isn't in a vehicle, announce that he/she is on foot
      outputChatBox ( getClientName ( thePlayer ) .. " is on foot" )
