weathersense @rain rain

After two seconds the processor turns the rain on and sees it immediately: the board shows rain: 1.

first	the kind of weather
second	where to put the answer: 1 or 0

Silent failure

Only a world processor can ask about the weather too. The instruction is privileged, like all the others in this part: an ordinary processor will not even assemble it — the parser replaces the line with an empty one, and the variable is left untouched.

That is not obvious: after all, a player sees the weather with their own eyes. But the game’s rule covers the whole category with no exceptions.

What it is for in a script

• a script checks itself: it turned a storm on, made sure it is running, and only then counted the task done;
• reacting to the map’s weather: on some maps weather comes on by itself, and a script can adapt — by giving the player a hint, for instance;
• a board: a world processor tells the player what is going on.

weathersense @sandstorm storm
jump 5 equal storm 0
control enabled projector1 1

Silent failure

The answer is only “running or not”. Logic knows neither the intensity nor the time left: mlog has no @weatherTime and no degree. If a script needs a duration, it turns the weather on itself and measures the time with a timer.

Remember

• weathersense kind where answers whether that weather is running.
• The instruction is privileged: unavailable to an ordinary processor, like the rest of the world ones.
• The answer is binary: neither the intensity nor the time left can be learned.
• Only a world processor can change the weather — weatherset.

Task

Change the kind in weathersense @rain rain to @fog: the board always shows zero — nobody turned any fog on.

Then change jump 3 lessThan @second 2 to jump 3 lessThan @second 10: the rain only starts at the tenth second, and until then the board honestly shows zero.
