Lavaarena

Based on game build 714014 | Last updated: 2026-03-05

Overview​

lavaarena is the world prefab responsible for initializing the Lava Arena seasonal mode environment. It configures tile collision, sets up dynamic wave effects for lava visuals, applies custom ambient lighting and sound (including reverb), and registers the world with the arena’s event system. It is not a component but a world-creation script that defines the arena’s structure and runtime behavior.

Usage example​

This file is not used directly as a component; instead, it is invoked by the engine via MakeWorld(...). Modders register Lava Arena as a world type and the engine instantiates it during world load. Custom usage is not intended.

-- Internal engine usage — modders should not instantiate directly.
return MakeWorld("lavaarena", prefabs, assets, common_postinit, master_postinit, { "lavaarena" }, {common_preinit = common_preinit, tile_physics_init = tile_physics_init})

Dependencies & tags​

Components used: ambientlighting, lavaarenamobtracker, wave, ambientsound, colourcube
Tags: Adds tag "lavaarena" to the world instance.
Prefabs required: 54 prefabs listed (including portals, mobs, stages, gear, and items).

Properties​

No public properties defined.

Main functions​

common_preinit(inst)​

  • Description: Runs early during world initialization. Modifies ground tile definitions to override the default falloff tile with a Lava Arena-specific variant and sets the map layer sampling style.
  • Parameters: inst (TheWorld) — the world entity.
  • Returns: Nothing.

tile_physics_init(inst)​

  • Description: Adds a custom tile collision set for land/ocean limits, making lava arena tiles impassable to non-player entities.
  • Parameters: inst (TheWorld) — the world entity.
  • Returns: Nothing.

common_postinit(inst)​

  • Description: Runs after the world is fully created and populated. Initializes lighting, mob tracking, wave physics (client-side only), ambient sound with lava reverb, and colour cube overrides. Registers a listener for player activation to update Friends settings.
  • Parameters: inst (TheWorld) — the world entity.
  • Returns: Nothing.

master_postinit(inst)​

  • Description: Delegates server-side initialization to a shared event data module for Lava Arena.
  • Parameters: inst (TheWorld) — the world entity.
  • Returns: Nothing.

Events & listeners​

  • Listens to: playeractivated — triggers TheNet:UpdatePlayingWithFriends() for the local player on the client.
  • Pushes: overrideambientlighting(Point) — sets override ambient light color.
  • Pushes: overrideambientsound — overrides tile sound type for lava arena surfaces.
  • Pushes: overridecolourcube — applies custom colour grading for the arena.

(None of the main functions fire custom events beyond those listed.)
