v1.3.0

[1.3.0] — 2026-06-07

Added

Entity binding

Attach a WebGUI interface to any entity. Players open it by right-clicking — no custom mod code required.

/webgui bind entity @e[type=villager,limit=1,sort=nearest] https://example.com/shop
/webgui bind entity @e[type=villager,limit=1,sort=nearest] https://example.com/shop true
/webgui unbind entity @e[type=villager,limit=1,sort=nearest]

• Bindings persist in config/webgui/entity_bindings.json and survive server restarts
• /webgui reload now also reloads entity bindings
• Optional cancel_interaction flag suppresses vanilla behaviour (trade screen, horse inventory, etc.)

URL placeholders

Substituted at interaction time:

Placeholder	Value
{entity_id} / {entity_uuid}	Entity UUID
{entity_type}	Namespaced type, e.g. minecraft:villager
{player_name} / {player_uuid}	The interacting player

Entity context in the browser

When a GUI is opened via entity interaction, window.webgui.entity is populated automatically — null when opened via command. A webgui:entity CustomEvent fires on every change.

interface WebGUIEntity {
  uuid: string
  type: string   // e.g. "minecraft:villager"
  name: string   // custom name if set, otherwise type display name
  pos:  { x: number; y: number; z: number }
}

Mod API

New methods in WebviewApi for use from other mods:

WebviewApi.bindEntity(uuid, "https://example.com/shop?npc={entity_id}", true);
WebviewApi.unbindEntity(uuid);
WebviewApi.getEntityBinding(uuid); // Optional<EntityBinding>
