Event Maker turns invisible triggers into datapack-driven events. Place walk-through volumes, or paint IDs onto normal blocks. When a player activates a gate, your commands run as that player — with multiplayer-safe one-shots built in.

Built for modpacks, adventure maps, and event servers that need scripted gates without command-block spaghetti.

Features

Event Trigger — no collision, invisible in Survival, cyan wireframe in Creative
Event Wand — inject a trigger ID onto any block without replacing it
Shared IDs — many blocks, one logical gate (doors, corridors, floors)
ID inheritance — newly placed Event Triggers reuse the last ID you set
Three activation modes — walk through, side touch, or step on
One-shot or persistent — fire once per player, or re-fire after leave + re-enter
Server-ready — one-shots are per player; markers stay so others can still activate
Datapack / KubeJS — define commands in JSON under event_trigger/
Admin commands — reset, check, or mark one-shot progress

Quick start

Creative → Event Maker tab → place Event Trigger blocks (or use the Event Wand on existing blocks)
Set an ID, e.g. welcome or mypack:arena_enter
Add matching datapack data (examples below)
Switch to Survival and activate the gate — commands run for that player

Event Wand

Shift + right-click — set the wand’s trigger ID
Right-click a block — assign that ID (Event Trigger, or inject onto any other block)
Left-click an injected block — clear the ID and outline (block stays)

Activation

Field	Values	Default
`activation`	`walk_through`, `touch`, `stepped_on`	`walk_through`
`persistent`	`true` / `false`	`false`
`commands`	list of command strings	required

walk_through — player enters the block volume
touch — player bumps the block from the sides (not from above)
stepped_on — player stands on top of the block
persistent: false — fires once per player; markers stay for everyone else
persistent: true — markers stay; fires again after that player fully leaves, then contacts again

Commands run as the triggering player (permission 2). Chat output is suppressed. @s is that player.

Datapack / KubeJS

Put files under:

data/<namespace>/event_trigger/

Or with KubeJS:

kubejs/data/<namespace>/event_trigger/

Run /reload after editing.

All IDs in one file (recommended)

Filename is arbitrary (e.g. events.json):

{
  "welcome": {
    "activation": "walk_through",
    "persistent": false,
    "commands": [
      "title @s actionbar {\"text\":\"Welcome!\",\"color\":\"green\"}",
      "give @s minecraft:bread 1"
    ]
  },
  "pressure": {
    "activation": "stepped_on",
    "persistent": true,
    "commands": [
      "title @s actionbar {\"text\":\"Stepped\"}"
    ]
  },
  "bump": {
    "activation": "touch",
    "commands": [
      "playsound minecraft:entity.experience_orb.pickup player @s"
    ]
  }
}

Keys become IDs in that namespace (eventmaker:welcome, …). Full namespace:path keys work too.

One file per ID

data/eventmaker/event_trigger/welcome.json:

{
  "activation": "walk_through",
  "commands": [
    "title @s actionbar {\"text\":\"Welcome!\",\"color\":\"green\"}"
  ]
}

File path is the ID. For mypack:arena_enter, use data/mypack/event_trigger/arena_enter.json.

Server commands

Permission level 2. Manage per-player one-shot progress:

/eventmaker reset <players> [id] — clear progress for players (all IDs, or one ID)
/eventmaker resetall [id] — clear progress for everyone
/eventmaker check <player> [id] — list consumed IDs, or check one ID
/eventmaker mark <players> <id> — mark an ID as already consumed

IDs accept path or namespace:path. Reset also clears contact state, so a player still standing in the gate can fire again immediately.
