Recipe: a door that opens when you walk up
New in 1.64. The door opens as a player walks up to it and closes when they walk away. This is the "On Near" pattern: a sensor zone around the door, with On Enter to open and On Exit to close. Because the zone is checked by the physics, everyone sees the same door move.
Make it
- Select the door.
- In the node editor, right-click the pane ▸ Recipes ▸ Door (opens when you walk up).
- Press Play and walk to the door.
What it adds
A zone in the scene: a translucent box, 3 × 2.4 × 3 m, centred on the door, named ‹door› zone. It is a static sensor (Physics ▸ Sensor): you walk through it, and it notices you.
Nodes in the door's own flow:
| Node | Set to |
|---|---|
| On Enter | who player, wired into an Object Selector picking the zone, and into Toggle Animation's open |
| On Exit | who player, wired into a second Object Selector picking the zone, and into close |
| Toggle Animation | closed = where the door stands, open = a quarter turn; sound door |
All of it — the zone and the nodes — is one undo step, shared with everyone in the session.
Make it your own
- A bigger or smaller reach: scale the zone. Hide it (Inspector ▸ visibility) if you do not want it seen; it still works.
- Let objects open it too (a cart, a ball): set who to any on both triggers.
- Swing on the hinge: see the click door.
- It does not open? The On Enter card says why: won't fire: physics is not running or blocked: not the player (Why did this not fire?).
A Proximity with to: player also tells you a player is near, but each player measures their own distance, so it suits a sign that lights for whoever is close rather than a door everyone shares.
