Global Interactions?

Hello there, I’m trying to get it so that when the player collides with a key somewhere in the level, a door opens (no animations, I’d rather the door just delete itself). I tried having a value called “open door” being set to one upon key collection, but I can’t seem to find any “if” statement commands or anything like that to add to the door’s bundle. Any tips?

Just “collide” in key. Sends message to door, and door opens

I’m sorry, could you elaborate a bit more? So I add a collision block and what block am I supposed to attach it to?

A message

Here’s an example:

Basically, when you contact the key have it send a message named something like “open” to the door. Have the door listen for the message named “open” with a mailbox, and when the message comes in, then open.
