-# Weather Tutorial
-
-
-This tutorial will have us create a simple weather system for our MUD.  The way we want to use this
-is to have all outdoor rooms echo weather-related messages to the room at regular and semi-random
-intervals. Things like "Clouds gather above", "It starts to rain" and so on.
-
-One could imagine every outdoor room in the game having a script running on themselves that fires
-regularly. For this particular example it is however more efficient to do it another way, namely by
-using a "ticker-subscription" model. The principle is simple: Instead of having each Object
-individually track the time, they instead subscribe to be called by a global ticker who handles time
-keeping.  Not only does this centralize and organize much of the code in one place, it also has less
-computing overhead.
-
-Evennia offers the [TickerHandler](TickerHandler) specifically for using the subscription model. We
-will use it for our weather system.
-
-We will assume you know how to make your own Typeclasses. If not see one of the beginning tutorials.
-We will create a new WeatherRoom typeclass that is aware of the day-night cycle.
-
-```python
-
-    import random
-    from evennia import DefaultRoom, TICKER_HANDLER
-    
-    ECHOES = ["The sky is clear.", 
-              "Clouds gather overhead.",
-              "It's starting to drizzle.",
-              "A breeze of wind is felt.",
-              "The wind is picking up"] # etc  
-
-    class WeatherRoom(DefaultRoom):
-        "This room is ticked at regular intervals"        
-       
-        def at_object_creation(self):
-            "called only when the object is first created"
-            TICKER_HANDLER.add(60 * 60, self.at_weather_update)
-
-        def at_weather_update(self, *args, **kwargs):
-            "ticked at regular intervals"
-            echo = random.choice(ECHOES)
-            self.msg_contents(echo)
-```
-
-In the `at_object_creation` method, we simply added ourselves to the TickerHandler and tell it to
-call `at_weather_update` every hour (`60*60` seconds). During testing you might want to play with a
-shorter time duration.
-
-For this to work we also create a custom hook `at_weather_update(*args, **kwargs)`, which is the
-call sign required by TickerHandler hooks.
-
-Henceforth the room will inform everyone inside it when the weather changes. This particular example
-is of course very simplistic - the weather echoes are just randomly chosen and don't care what
-weather came before it. Expanding it to be more realistic is a useful exercise.
