Weather Set

Weather on a map is not chance but a state a script can control

weatherset @rain true

After two seconds the world processor turns the rain on and immediately checks itself with weathersense: the board shows rain: 1.

Field	What is in it
first	the kind of weather: @rain, @snowing, @sandstorm, @sporestorm, @fog
second	on or off

Six kinds

Constant	What it is
@rain	rain
@snowing	snow
@sandstorm	a sandstorm
@sporestorm	a spore storm
@fog	fog
@suspend-particles	particles hanging in the air

The names come from the content itself, and they do not always match what you would expect: snow is called @snowing, not @snow.

Note

Weather is not only a picture. In the game it gets in the way: a storm damages units, spores poison, fog hides the view. So turning weather on in a script is a complication, not a decoration.

Weather stays on for good

Silent failure

Weather turned on by logic does not end by itself. Ordinary weather on a map comes and goes on its own schedule, while weather set by weatherset holds until it is turned off:

weatherset @sandstorm false

So a script that turned a storm on for a minute has to turn it off itself — by a timer, a flag or an event.

Note

The course sandbox does not show weather: the instructions work, but no snow and no rain are visible. In the game weather runs as usual.

Remember

• weatherset kind on controls the weather on a map.
• There are six kinds; the names are content constants, @snowing rather than @snow.
• Weather turned on by logic does not stop by itself.
• The instruction is privileged: world processors only.

Task

Change @rain to @sandstorm in the example’s weatherset line: the board stops showing rain — a different kind of weather is running while the question is about rain.

Then add print storm after print rain: the storm comes out as one and the rain as zero.
