Member Function Documentation

◆ reset()

void MADS::Phantom::AdlibChannel::reset ( )

Zeroes the "live" fields of one channel without touching loop/sound-data pointers (those are handled separately by AdlibChannel_load).

◆ load()

void MADS::Phantom::AdlibChannel::load ( byte *  soundData)

Clears the entire channel struct, then initialises the loop/source pointers to the supplied sound-data address and marks the channel active.

◆ setPtr2()

void MADS::Phantom::AdlibChannel::setPtr2 ( byte *  ptr)

Point a channel at the null/silence data and arm a one-step volume fade so it fades out gracefully.

◆ enable()

void MADS::Phantom::AdlibChannel::enable ( )

Mark a channel as pending-stop and redirect its sound-data pointer to the null/silence stream.

◆ processChannelFade()

void MADS::Phantom::AdlibChannel::processChannelFade ( )

Called every frame for each channel. When _pendingStop is set, waits until both velocity and volume are zero before marking the channel idle; otherwise arms a fade-down of velocity/volume each period.
