Datapack events

An event file is small. It needs a commands_poll. Everything else is flavor.

• activation: walk_through, touch, stepped_on
• persistent: one-shot or it can fire again
• command_location: free (the player) or event_location (your orange markers)
• command_location_range: how far to look for those markers (default 32)

free is “run this as the player who tripped it.” Good for a tellraw, a title, giving an item.

event_location is “run this once per matching orange marker in range, standing on that block.” Good for filling a cauldron, opening a door two blocks away, summoning a mob in the pit, not on the player’s head.

If you stamp the same corridor six times and reuse the ids, range keeps each copy local. A one-shot in room A does not eat room B.

A first event people actually ship: walk through a tripwire-looking air block, play a sound, setblock a barrier out of the way. Poll has one command. Event is walk_through, one-shot, free or event_location depending on where the door sits.
