Field Documentation

stg_id_t _stg_world::id
 

Stage's unique identifier for this world.

GHashTable* _stg_world::models
 

the models that make up the world, indexed by id

GHashTable* _stg_world::models_by_name
 

the models that make up the world, indexed by name

stg_meters_t _stg_world::width
 

x size of the world

stg_meters_t _stg_world::height
 

y size of the world

int _stg_world::child_type_count[256]
 

the number of models of each type is counted so we can automatically generate names for them

struct _stg_matrix* _stg_world::matrix
 

occupancy quadtree for model raytracing

char* _stg_world::token
 

the name of this world

stg_msec_t _stg_world::sim_time
 

the current time in this world

stg_msec_t _stg_world::sim_interval
 

this much simulated time elapses each step.

stg_msec_t _stg_world::wall_interval
 

real-time interval between updates - set this to zero for 'as fast as possible'

stg_msec_t _stg_world::wall_last_update
 

the wall-clock time of the last update

stg_msec_t _stg_world::real_interval_measured
 

the wallclock-time interval elapsed between the last two updates - compare this with sim_interval to see the ratio of sim to real time

double _stg_world::ppm
 

the resolution of the world model in pixels per meter

gboolean _stg_world::paused
 

the world only updates when this is zero

gboolean _stg_world::destroy
 

this world should be destroyed ASAP

gui_window_t* _stg_world::win
 

the gui window associated with this world

int _stg_world::subs
 

the total number of subscriptions to all models
