TimeOfDay

Author: Berenger

Description

Compute the game time into hours, minutes and seconds depending on the duration of a day. Return either a string, a percentage or the components hours, minutes, seconds.

Usage

Just put the script in Standard Assets, and use it that way :

void Start()
{
	TimeOfDay.dayDuration = 10f;
}
 
void Update()
{
	print( TimeOfDay.GetTimeOfDay() + " Days : " + TimeOfDay.Days() );
}
