How to Set Move Route with script?

[PhotonWeapon]

What's the script to set an event's or the player's move route?

Or, more specifically, how do I get an event/player to move to a certain x/y on the map, and at certain speeds? Like, say, I wanted Old Man to walk right next to Old Lady but don't want to remember all the Move Speed Ups, Walk Rights, Walk Lefts, Move Speed Downs, etc. Instead he'd move to Old Lady's X(-1),Y coordinate.

NOTE: This isn't the same as Set Event Location, which would instantly put an event at another place. This one's where the event is actually physically moving over there.

There are some Pathfinding scripts around the submitted scripts section which allow you to move the player or an event to variable coordinates. I'll edit this post with a link when I dig one up.

EDIT: Here's the one I was thinking of

      new_positions = []
    }
    return [false, nil, nil]
  end
end

class Interpreter
  #--------------------------------------------------------------------------
  def event
    return $game_map.events[@event_id]
  end
end

To move the player to a certain location, call "$game_player.find_path(X, Y)". For an event, call "$game_map.events[EVENT_ID].find_path(X, Y)"

Be sure to replace X, Y, and EVENT_ID with the appropriate values.

Cool, it's working. Not everything, though -- Wait for Move Completion doesn't work (probably because it's through Call Script?). Also, instead of a set x,y is there a way to move to another event's x,y?

 

[Astromech]

Yes, wait for move completion won't work with this script. This should be a work around though:

@> Loop
     @> Wait 1 Frame
     @> Conditional Branch: Script: not $game_map.events[EVENT_ID].runpath
          @> Break Loop
     @> Repeat above

As for the other problem call this script

x = $game_map.events[EVENT_ID1].x
y = $game_map.events[EVENT_ID1].y
$game_map.events[EVENT_ID2].find_path(x, y)

where EVENT_ID1 is the event that you want EVENT_ID2 to move to. Of course you can substitute the player in there as well.

It works! Thank you so much! :D
