Flooding

Flooding is a mechanic that can prevent buildings from functioning and most plants from growing. There is no indication in game as to whether or not a building is susceptible to flooding.

Usage

Substantial Liquid

A tile of liquid is considered substantial if the mass is at least 35% Default Mass for the liquid type in a tile. For example, the default mass of water in a tile is 1000 kg, so a tile of water is considered substantial if the mass is at least 350 kg.

Flooding Events

A building becomes flooded when:

• On loading a save, any building submerged in a tile of substantial liquid will become flooded.
• Through normal gameplay, a building becomes flooded when a tile of substantial liquid occupies its space.

A building becomes no longer flooded when:

• On loading a save, any building submerged in a tile of insubstantial liquid will become no longer flooded even if it had a flooded status when saved.
• Through normal gameplay, the liquid elements occupying the building changes. This usually means the liquid must be completely removed to cancel the flooded status. Sometimes, requires mopping up the last few drops. Demolishing and reconstructing the building will fix the status as well.

Buildings immune to flooding:

• Algae Terrarium
• Tasteful Memorial
• Water Cooler
• Desalinator
• Canister Filler and Canister Emptier
• All sensors, switches, meters and filters for conveyors, liquid and gas piping
• All Decor items that only function as decorations
• All Automation
• All Rocketry components, except Gantry and both telescopes
• Auto-Sweeper, Conveyor Loader, Robo-Miner
• Thermo Aquatuner
• Liquid Pump and Mini Liquid Pump
• All solid tiles
• All storage containers, including Automatic Dispensers, Conveyor Receptacles and Refrigerators

Tips

• Submerged Atmo Sensors always return a value of 0 g, which can cause them to send green if set below any value.
• Thimble Reed and Seakomb are the only plant that can grow fully submerged.
• Waterweed actually floods very easily and becomes Too Wet to grow.
