This section explains how to have the partner trainer's event follow the player as they walk around the map. More generally, it explains how to make any event follow the player - the follower mechanic is not solely for partner trainers (it just makes sense to use a dependent event for a registered partner).
While the player has any followers, the player cannot use the moves Surf, Fly, Teleport or Dig outside battle, nor use an Escape Rope. The player can talk to the follower, but the contents of that interaction must be in a Common Event rather than in a page in that dependent event. A follower will automatically stop following the player if they black out.
Making an event a follower
When registering a partner trainer, you will typically also want to make that trainer's event a follower. To do this, use the following line of code:
Ruby：
Followers.add(@event_id, "Dave", 42)
The first argument is the ID number of the event from the current
map that will follow the player (@event_id means the event that this script is used in). The second argument is a name or phrase used to identify the follower (useful when making them stop following later on). The third argument is the number of the Common Event to run when the player talks to the follower.
