◆ ReGenerate()

bool Weather::ReGenerate ( )

#include <azerothcore-wotlk/src/server/game/Weather/Weather.h>

Calculate the new weather.

Weather statistics:

30% - no change
30% - weather gets better (if not fine) or change weather type
30% - weather worsens (if not fine)
10% - radical change (if not fine)

Radical change:

if light -> heavy
if medium -> change weather type
if heavy -> 50% light, 50% change weather type

New weather statistics (if not fine):

85% light
7% medium
7% heavy If fine 100% sun (no fog)
