Collect to Open

Send a message when a key is collected to open one or more doors in range with the same tag.

Object 1 - MP

Asset: Door
Tags: Door

DOOR BEHAVIOR
Triggered by: Message
Trigger (Open): Key.Collected

---

Object 2 - MP

Asset: Key

COLLECTABLE COMPONENT
Triggered by: Collect (collision)
Send: Key.Collected
Broadcast Type: SpecificTagsInRange → Door
Range: Adjust as needed*

*Adjust range so any doors to be opened by the key are located within the key’s yellow sphere. This indicates how far the key’s message can be sent.

Note

One key can open any door with the tag you choose using this method. You can use this schema multiple times to have multiple keys that only open certain doors for a fun challenge, like a maze.

Collect to Unlock

Instead of opening the door(s) when the key is collected, trigger a toggle component to unlock the door behavior(s), then interact with the door(s) to open. This feels more realistic.

Trigger (On): Key.Collected
