Core Mechanics

Gas Physics

Gases behave like fluids but with varying densities. Rising gases will accumulate against ceilings, while sinking gases will pool in pits and tunnels. Gases spread from high concentration to low concentration until they dissipate or fill a space.

Combustion and Explosions

Exposing flammable gases (like Natural Gas) or explosive gases (like Red Gas or Coal Dust) to an open flame will cause an immediate reaction. * Torches: Placing a torch in a gas-filled room is the most common cause of accidental explosions. * Fire: Any fire block or 'Ignited Gas' will trigger a chain reaction. * Pipes: If a pipe containing explosive gas is destroyed by an explosion, it can cause a chain reaction through the entire piping network.

Suffocation and Toxicity

Most gases are unbreathable. Standing in a gas cloud without protection will deplete your air meter faster than water and eventually deal suffocation damage. Specific gases like Chlorine or Acidic Vapour deal direct damage or status effects like Blindness and Slowness.

Blocks and Machinery

Piping System

To move and use gases, players must construct a piping network.

• Gas Pipe: The basic transport block. Available in Iron (high pressure tolerance), Glass (transparent, high tolerance), and Poor Man's (low tolerance, made of wood/cobble).
• Gas Collector: Sucks in gas from the surrounding 1-block radius and pushes it into connected pipes.
• Gas Pump (Propeller): Essential for long-distance transport. It provides pressure to move gas through pipes. Each pump has a 'Pressure Tolerance' (e.g., 15 blocks for Iron) before another pump is needed.
• Gas Tank: Stores large quantities of a single gas type. Can be used to fill Gas Bottles.

Utility Blocks

• Gas Furnace: A high-efficiency furnace that runs on flammable gases. It features a unique Temperature Mechanic: as it smelts, it heats up, increasing smelting speed significantly while maintaining the same gas consumption rate.
• Gas Dynamo: Converts flammable gases into Redstone Flux (RF) for use with other mods.
• Gas Vent: Safely releases gas from a pipe system into the atmosphere.
• Gas Sensor: Outputs a redstone signal when a specific gas is detected in front of it.

Items and Equipment

Survival Gear

• Lanterns: The only safe way to light gas-rich caves. They come in three types: Torch Lantern (dimmer), Gas Lantern (bright, uses gas bottles), and Glowstone Lantern (permanent full brightness).
• Primitive Respirator: A basic mask that prevents suffocation and slowness. It is repaired using Coal on an anvil.
• Advanced Respirator: Protects against all gas effects, including vision impairment (blindness).
• Gas Filter: Consumable item used to craft or repair respirators.

Tools

• Gas Sampler: Used to 'sample' a gas block. Once a sample is taken, the sampler can be placed inside a Gas Pump to act as a filter (Including or Excluding).
• Gas Bottle: Used to collect gas from tanks or the world for use in lanterns or furnaces.
• Gas Detector: A handheld tool that beeps when pointed toward a specific gas type within a 10-block range.
• Wrench: Used to rotate pipes and machinery.

Crafting Recipes

While recipes may vary slightly by version, the standard patterns are as follows:

Note: Use a Lantern + Torch/Gas Bottle/Glowstone in a crafting grid to create a functional Lantern.
