  • type: The type of element you want a list of. This can be any one of the following ten things MTA is programmed to understand:

Returns

Example

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
