===== Wetterscript =====
Mit diesem Script kann man das Wetter etwas zufälliger gestalten. Wer will kann es auch mal im MP ausprobieren und testen ob es DESYNCs gibt.

==== Anwendung ====
<code=lua>function InitWeather()
    -- Erstmal ganz normal das Wetter einstellen
    AddPeriodicSummer (300)
    AddPeriodicRain   ( 60)
    
    -- Jetzt die neuen Wetterperioden einstellen
    Weather.AddPeriodicSummer (240, 360) -- Minimum Dauer, Maximum Dauer
    Weather.AddPeriodicRain   ( 30,  90)
    Weather.AddPeriodicWinter (120, 240)
    
    -- Die Wetterlagen sollen nacheinander oder zufällig erscheinen? (WEATHER_PERIODIC oder WEATHER_RANDOM)
    Weather.SetOrder(WEATHER_PERIODIC)

    -- Starten!
    Weather.Init()
end</code>

==== Benötigter Code ====
<code=lua>StartSummerOrig = StartSummer
function StartSummer(_seconds) if Weather.IsActive then Weather.Init(_seconds) end StartSummerOrig(_seconds) end
StartRainOrig = StartRain
function StartRain(_seconds) if Weather.IsActive then Weather.Init(_seconds) end StartRainOrig(_seconds) end
StartWinterOrig = StartWinter
function StartWinter(_seconds) if Weather.IsActive then Weather.Init(_seconds) end StartWinterOrig(_seconds) end
GUI.SetWeatherOrig = GUI.SetWeather
function GUI.SetWeather(_weathertype) if Weather.IsActive then Weather.Init(300) end GUI.SetWeatherOrig(_weathertype) end
Logic.GetNextWeatherStateOrig = Logic.GetNextWeatherState
function Logic.GetNextWeatherState() if Weather.IsActive then return Weather.Next.Type end return Logic.GetNextWeatherStateOrig() end
Logic.GetTimeToNextWeatherPeriodOrig = Logic.GetTimeToNextWeatherPeriod
function Logic.GetTimeToNextWeatherPeriod() if Weather.IsActive then return Weather.TimeToNextWeatherPeriod end return Logic.GetTimeToNextWeatherPeriodOrig() end

    end 
    
    Data.Duration = GetRandom(Weather.Periods[Data.Index][2], Weather.Periods[Data.Index][3])
    Data.Type = Weather.Periods[Data.Index][4]
    
    return Data
end

Weather.SetOrder          = function(_order) Weather.Order = _order end
Weather.AddPeriodicSummer = function(_min, _max) table.insert(Weather.Periods, {StartSummerOrig, _min, _max, 1}) end
Weather.AddPeriodicRain   = function(_min, _max) table.insert(Weather.Periods, {StartRainOrig,   _min, _max, 2}) end
Weather.AddPeriodicWinter = function(_min, _max) table.insert(Weather.Periods, {StartWinterOrig, _min, _max, 3}) end</code>

==== Zusätzlicher Code ====
Mit diesem zusätzlichen optionalen Code werden bessere Zufallszahlen erzeugt.
