Raindomeover

Based on game build 714014 | Last updated: 2026-03-08

Overview​

RainDomeOver is a UI widget that visualizes the cumulative effect of active rain domes in the environment. It calculates the spatial influence of nearby rain domes, blends their contributions based on proximity, and updates the position, scale, and opacity of an on-screen overlay. It interacts with the raindome component to query dome radius and position, and responds to world events (underraindomes and exitraindome) to show or hide itself accordingly.

Usage example​

This widget is typically instantiated automatically by the game and does not need manual initialization. However, for reference:

local widget = CreateWidget("RainDomeOver", owner)
-- The widget listens to "underraindomes" and "exitraindome" events on owner.inst
-- It updates automatically while active (via OnUpdate) and hides when no domes are active.

Dependencies & tags​

Properties​

No public properties are exposed by this widget. All state is managed internally.

Main functions​

OnUpdate(dt)​

  • Description: Called periodically while the widget is visible and updating. Computes weighted contributions from all valid rain domes to determine overlay position, scale, and intensity; updates the background image's fade alpha.
  • Parameters: dt (number) — delta time in seconds since last frame.
  • Returns: Nothing.
  • Error states: If self.domes is nil or empty, no updates are applied beyond resetting the background fade alpha to 0.

Events & listeners​

  • Listens to:
    • underraindomes — fired when rain domes become active; initializes self.domes and starts the update loop.
    • exitraindome — fired when the player exits the dome-affected area; clears self.domes, stops updating, and hides the widget.
  • Pushes: None.
