The SetSFXOnOff() function turns on or off all the sounds associated with this Object3d class.
(See Listing 6-4.)
Listing 6-4. Turning the SFX On or Off
void SetSFXOnOff(boolean Value)
{
for (int i = 0; i < m_NumberSounds;i++)
{
m_SoundEffectsOn[i] = Value;
}
}
The AddSound() function creates a new Sound class object from a resource ResourceID and the
sound pool Pool and adds the sound to the m_SoundEffects array that holds the sound effects for
this class. (See Listing 6-5.)
Listing 6-5. Creating a New Sound from a Resource
int AddSound(SoundPool Pool, int ResourceID)
{
int SoundIndex = -1;
Sound SFX = new Sound(m_Context, Pool, ResourceID);
SoundIndex = AddSound(SFX);
return SoundIndex;
}
The PlaySound() function plays the sound effect that is associated with the SoundIndex input
parameter for this class. Recall that each time a new sound is added to this Object3d class, an index
handle is returned. You must use this index handle as input to the PlaySound() function, if you want
to play the sound back. (See Listing 6-6.)
Listing 6-6. Playing the Sound
void PlaySound(int SoundIndex)
{
if ((SoundIndex < m_NumberSounds) &&
(m_SoundEffectsOn[SoundIndex]))
{
// Play Sound
m_SoundEffects[SoundIndex].PlaySound();
}
else
{
Log.e("OBJECT3D", "ERROR IN PLAYING SOUND, SOUNDINDEX = " + SoundIndex);
}
}
