Overview
Weather is a dynamic system that creates moving weather effects across the world map. Clouds drift across the wasteland, bringing rain, radioactive winds, acid storms to surface locations. Weather only affects outdoor maps — interior and underground locations maintain their own preset conditions.
How Weather Works
Clouds
The weather system spawns up to 10 clouds at random positions on the world map. Each cloud carries one weather effect based on a rarity roll:
- Rain — most common, standard rainfall
- Radiation Wind — radioactive dust carried by the wind
- Acid Rain — rare, green-tinted corrosive rain
Clouds drift over time, moving one zone diagonally per tick. When a cloud passes over a zone, its weather effect is applied to all surface maps in that zone. Once a cloud drifts off the edge of the world map, it is removed and a new cloud spawns elsewhere.
Weather Progression
Weather advances through the event scheduler. This means weather changes gradually and unpredictably.
Surface vs Interior
Weather only affects surface maps — locations with natural daylight. Indoor maps, caves, bunkers, and dungeons use their own default weather setting, which typically means clear conditions (no rain, no wind). A map's default weather is set by the map designer.
Weather Types
| Weather | Visual Effect | Description |
|---|---|---|
| Clear | None | No weather, clear skies. Default for most interior maps. |
| Rain | Standard rain | Falling rain with splashing drops. Most common outdoor weather. |
| Acid Rain | Green rain | Corrosive green-tinted rainfall. Visually distinct from normal rain. |
| Radiation Wind | Radioactive dust | Wind-carried radioactive particles. Lower visibility. |
| Radiation Fall | Radioactive particles | Heavy radioactive fallout settling on the ground. |
| Snowfall | Snow | Snowflakes falling and melting on contact. (Event) |
Each weather type has a defined intensity (capacity), horizontal speed, and vertical speed that determine how heavy and fast the effect appears visually.
Client Settings
Weather rendering can be disabled client-side for performance or visibility reasons. When disabled, all weather effects are cleared and maps are refreshed without any precipitation or wind visuals.
