Method Details

get

public static WeatherUpdater get()

Get the WeatherUpdater instance.

Returns:

singleton instance

manageAttributes

public void manageAttributes(ZoneAttributes attr,
 String desc)

Make a zone weather managed by the weather updater. Modifiers to the default weather can be described in form "varying(rain=value1, temperature=value2, fog=value3)", where any or all of the modifiers can be omitted, and their order does not matter. Description parameter "varying" is interpreted as "varying()", that is, no weather modifiers.
The values are interpreted so that:

• One step of rain corresponds to adding about 5% to rain probability
• One step of temperature corresponds roughly to one month of time difference (compared to coldest month).
• One step of fog corresponds to adding about 5% to fog probability

Negative values are interpreted as corresponding decreases. Note that rain and especially fog have low probabilities to begin with, so they get easily turned off completely.
If a modifier is specified more than once, the last one takes effect.

Parameters:

attr - Attributes of the zone

desc - The weather attribute value specified for the zone. This is used to determine any zone specific modifiers

onTurnReached

public final void onTurnReached(int currentTurn)

Description copied from interface: TurnListener

Specified by:

onTurnReached in interface TurnListener
