Private Methods

void	advance_param (dynparam *p) Update the dynamic parameters of a wave
void	advance_wave (wave *p) Update a wave's parameters
double	calc_value (double t, float src, float dat, float type) Calculate the new value of a dynamic parameter
void	free_wave (wave *p) Place a wave on the list of available waves
float*	init_new_param (dynparam *p, float *data, double start) Initialize the dynamic parameter values for a new wave
void	init_new_wave (wave *p, float *data, int datalen) Set the initial values for a new wave
wave*	new_wave (void) Get a new wave from the free waves list

Simulator()

Constructor. Initialize all variables. Set up initial list of free waves

~Simulator()

Destructor. Free all active waves and wave on the avail. list.

Simulator(const Simulator &)

Copy constructor.

const Simulator& operator=(const Simulator &)

Overloaded assignment operator.

void prep_simulator(void)

Kill any simulation currently running. Get a new Card_DB Load the score of the new song, and set times and mode.

void advance_simulator(void)

Update times. Check to see if mode has changed or left wand button has been pressed. Start the sound file playing or update current waves accordingly. Check to see if simulation has finished.

int wave_lock_init(void)

Return wave_lock_initizlied variable.

CAVELOCK get_wave_lock(void)

Return wave_lock variable.

int simulation_go(void)

Return variable sim_go.

void set_sim_go(int)

Set variable sim_go to true if its state changes.

double get_frame_time(void)

Return time variable frame_time.

wave* get_active_waves(void)

Return a pointer to the active_waves list.

void kill_simulation(void)

Delete active waves and Card_DB. Set current times to 0.

wave* new_wave(void)

Get a new wave from the free waves list. If one is not available, allocate space for a new one.

Returns:

Address of a new wave

void free_wave(wave *p)

Place a wave on the list of available waves

Parameters:

p - The wave to be freed.

void advance_wave(wave *p)

Update a wave's parameters

Parameters:

p - Wave to be updated.

void advance_param(dynparam *p)

Update the dynamic parameters of a wave. Called from advance_wave.

Parameters:

p - Struct containg dynamic parameters for update.

See Also:

advance_wave.

double calc_value(double t, float src, float dat, float type)

Calculate the new value of a dynamic parameter. Called from advance_param.

Parameters:

t - The current time.
src - Current value.
dat - Current value incremented.
type - Type of function used to calculate.

See Also:

advance_param

void init_new_wave(wave *p, float *data, int datalen)

Set the initial values for a new wave

Parameters:

p - Pointer to the new wave.
data - Pointer to the data for the wave.
datalen - Number of data entries.

float* init_new_param(dynparam *p, float *data, double start)

Initialize the dynamic parameter values for a new wave. Called from init_new_wave.

Parameters:

p - Pointer to the dynamic parameters to be initialized.
data - Pointer to the data for the parameters.
start - Current time.
