Function Documentation

dawn_to_dusk()

static void dawn_to_dusk ( const timeofday_t *  tod )

static

Compute the darkness level for all loaded maps in the game.

Parameters

tod	time of day to compute darkness for.

get_world_darkness()

int get_world_darkness

(

)

Get the darkness of the world map at this point.

Since the darkness of the world map is uniform, we can get away with this calculation.

Returns

The darkenss value of the world at the current time.

mapstruct *

m

)

Set the darkness level for a map, based on the time of the day.

Parameters

m	map to alter.

tick_the_clock()

void tick_the_clock

(

void

)

This performs the basic function of advancing the clock one tick forward.

Every 20 ticks, the clock is saved to disk. It is also saved on shutdown. Any time dependant functions should be called from this function, and probably be passed tod as an argument. Please don't modify tod in the dependant function.
