Why doesn't this script work?

Spoiler

if $game_party.actors == 4
  $game_player.move_up
end

It was supposed to make the player move up if there were 4 players in the party. It has a syntax error. Help?
Also, how would I make it display text when it pushes me forward? In case your wondering what this is for, I'm making a monster collecting game. When you try to enter the ranch (moving down into it) with 4 actors already, it kicks you out and you have to go deposit some.

Try:

if $game_party.actors.size == 4
 $game_player.move_up
end

If i remember right, $game_party.actors is an array, so you need to use its size method.

Thanks, it does work. Do you know the answer to my other question? (text)

 

[Gleen]

So you wanna show a message saying "You can't enter this time, do something", or similar? If the answer is yes, why don't you do this with events?

Assuming you are already using that in an event command, you can change the commands to:

@>Conditional Branch: Script: $game_party.actors.size == 4
   @>Script: $game_player.move_up
   @>Text: Whatever you want to say here
   @>
 :  Branch End
@>

If it's in a script in the script editor, just add...

if $game_party.actors == 4
  $game_player.move_up
  $game_temp.message_text = "Whatever you want to say here"
end

*facepalm* My mistake. I forgot I was doing this in events. My bad lol.
