* Plant growth - Most plants have light requirements to grow.

* Colonists want 30% light or better. This affects:

:* Colonists' movement speed - Colonists in darkness will have a reduced [[move speed]], scaling to 80% at a light level of 0%. Due to this, combat at night or under unlit roofed areas can lead to a disadvantage against non-human opponents, such as insects, manhunter animals, or mechanoids. Pawns that are [[Sight|Blind]], have the [[Ideoligion#Lighting|Lighting: Darklight preferred]] precept,{{IdeologyIcon}} or have the [[Dark vision]] gene{{BiotechIcon}} are unaffected by this factor.

:* Colonists' global work speed - Similarly to their movement speed, colonists will have a work speed penalty when working in darkness, scaling to 80% at a light level of 0%. Pawns that are [[Sight|Blind]], have the [[Ideoligion#Lighting|Lighting: Darklight preferred]] precept,{{IdeologyIcon}} or have the [[Dark vision]] gene{{BiotechIcon}} are unaffected by this factor.

Light in roofed areas is provided by the following appliances:

Daylight, or natural light, is the light generated on unroofed tiles throughout the map. The timing and strength of daylight is affected by latitude, time of year, and time of day, due to the planet's apparent axial tilt.

# The latitude normal vector <code>N</code> can be calculated as the vector <code>{cos(''latitude''), sin(''latitude''), 0}</code>. Note that this is always orthogonal to the Z-axis (the Y-axis passes through the planet's poles, not the Z-axis) with a positive X-value. For example, the latitude normal vector at the equator would be <code>{1, 0, 0}</code> while at 45° N it would be <code>{0.707, 0.707, 0}</code>.

# The unmodified sun position vector <code>P</code> is the vector <code>{cos((''day_percent'' - 0.5) &times; 360°), -cos(''day_of_year''/60 &times; 360°) &times; ''latitude_fraction'', sin((''day_percent'' - 0.5) &times; 360°)}</code>.

# Rotate the normalized sun position vector <code>P</code> an amount towards latitude normal vector <code>N</code> based on the graph on the right, but not passing it (if applicable).

# The unmodified daylight intensity is equal to the [[wikipedia:Dot product|dot product]] of the latitude normal vector <code>N</code> and sun position vector <code>P</code> (both should have magnitude <code>1.0</code>).

# The final daylight intensity scales based on the unmodified daylight intensity, with <code>0.0</code> to <code>0.7</code> linearly corresponding with 0% to 100% light intensity and <code>0.7</code> to <code>1.0</code> being clamped at 100% light intensity.

The steam geyser sprays after a random delay between {{Ticks|500}} and {{Ticks|2000}}. It will then spray for between {{Ticks|200}} and {{Ticks|500}}. While spraying, it will output 40 heat every {{ticks|20}}. Thus, it averages {{#expr: (60*40*((500+200)/2)/20)/((2000+500/2) + (200+500)/2) round 2}} heat per second, with no maximum temperature.  

Besides their use in power generation, they can also be used to heat bases and greenhouses without the need for electricity or fuel by sealing them in. Like any means of [[temperature]] regulation, geysers require an enclosed and [[roof|roofed]] [[room]] to actually cause a change in heat. If you don't want heat, keep the geothermal room without a roof.

{{stub|section=1|reason=Exact details of how large fires on the map cause rain needed. Rain details should be split from the rain weather type (because its not the only weather type that includes raining) and details discussed including short circuiting, increasing fuel consumption of torch, campfire and brazier variants, which weather types include rain, whether snow counts as rain for all mechanics etc, similarly Snow and its unique effects including [[Snow]] being merged into here}}

Weather events occur from time to time depending on the biome and time of year, with the current weather listed at the right edge of the screen. When a weather event ends the weather returns to Clear. Each weather event has a general effect on wind speed. Wind speed continually varies between 0% to 100% but it is not displayed onscreen. Wind speed is a direct multiplier of a wind turbine's power output. At 50% wind speed a wind turbine produces 1500W of its 3450W max. The [[Condition causer#Weather controller|"weather controller" condition causer]] {{RoyaltyIcon}} can force a single type of weather to constantly appear, and will only allow natural changes in weather once it is destroyed.

| An extreme version of the dry thunderstorm, and an event of its own (rather than normal weather changes). [[Lightning]] strike many times in a row in a small area, igniting anything flammable and causing giant wildfires which can spread to your base easily. It also disables rain for a short time.

'''Lightning''' is created either naturally through thunder and flashstorms, or artificially with the [[Psycasts#Flashstorm|flashstorm]] psycast{{RoyaltyIcon}}. These do 10 [[Damage types#Flame|Flame]] damage in a 3x3 area (1.9 block radius) and start [[fire]]s in the area of effect. Dry thunderstorms can be especially dangerous, starting fires around the map without rain to put them out. The flashstorm psycast should be used with caution, preferably in areas without vegetation or during rain. Lightning can also be spawned in with a debug command in [[development mode]].

* Beta 19/ 1.0 - Changed deep moving water to chest-deep moving water: walkable but slower than shallow water. Shallow water movement cost 12 -> 22. Sand fertility 6% -> 10%.
