sound_pool object

This method will update the position of the sounds according to the listener's new position on a 1d grid.

void update_listener_1d(int listener_x)

Parameters:
listener_x
The new position of the listener on the grid.

Return value:
None.

Remarks:
This method is used when the listener has moved, meaning that all of the currently active sounds in the pool will move. To move individual sounds, use the update_sound methods.

Example:
#include "sound_pool.bgt"

sound_pool sound_environment;
timer walk_timer;

int player_position;
int step;

const string sound_extension=".wav";

const int left=-1;
const int right=1;

const int boundary=200;

void main()
{
show_game_window("sound_pool test");
sound_environment.max_distance=70;
for(int counter=1; counter<15; counter++)
{
sound_environment.play_extended_1d("sounds/sound"+counter+sound_extension, 0, random(0, boundary), -10, 10, true, 0, false);
}
while(true)
{
check_input();
wait(5);
}
}

void check_input()
{
if((key_down(KEY_LMENU))&&(key_pressed(KEY_F4)))
{
exit();
}
if(key_down(KEY_LEFT))
{
walk(left);
}
if(key_down(KEY_RIGHT))
{
walk(right);
}
}

void walk(int direction)
{
if((direction<=left)&&(player_position<=0))
{
return;
}
if((direction>=right)&&(player_position>=boundary))
{
return;
}
if(walk_timer.elapsed<350)
{
return;
}
step++;
if(step>6)
{
step=1;
}
walk_timer.restart();
player_position+=direction;
sound_environment.play_stationary("sounds/steps/"+step+sound_extension, false);
sound_environment.update_listener_1d(player_position);
}
