SDL::Mixer::Groups - Audio channel group functions CATEGORY
Mixer METHODS
reserve_channels my $reserved = SDL::Mixer::Groups::reserve_channels( $num ); $num is the number of channels to reserve from default mixing. Zero removes all reservations. Reserve $num channels from being used when playing samples when passing in "-1" as a channel number to playback functions. The channels are reserved starting from channel 0 to "$num-1". Passing in zero will unreserve all channels. Normally SDL_mixer starts without any channels reserved. The following functions are affected by this setting: o SDL::Mixer::Channels::play_channel o SDL::Mixer::Channels::play_channel_timed o SDL::Mixer::Channels::fade_in_channel o SDL::Mixer::Channels::fade_in_channel_timed Returns: The number of channels reserved. Never fails, but may return less channels than you ask for, depending on the number of channels previously allocated (see SDL::Mixer::Channels::allocate_channels). group_channel my $grouped = SDL::Mixer::Groups::group_channel( $channel, $group ); Add a channel to group id (any positive integer), or reset it's group to the default group by passing (-1). Returns: True(1) on success. False(0) is returned when the channel specified is invalid. group_channels my $grouped = SDL::Mixer::Groups::group_channels( $from_channel, $to_channel, $group ); Add a range of channels to group id (any positive integer), or reset their group to the default group by passing (-1). Returns: The number of affected channels. group_available my $channel = SDL::Mixer::Groups::group_count( $group ); "group_newer" returns the first available channel of this group. group_count my $channels = SDL::Mixer::Groups::group_count( $group ); "group_newer" returns the number of channels in this group. group_oldest my $channel = SDL::Mixer::Groups::group_oldest( $group ); "group_newer" returns the channel number which started to play at first. group_newer my $channel = SDL::Mixer::Groups::group_newer( $group ); "group_newer" returns the channel number which started to play at last. fade_out_group SDL::Mixer::Groups::fade_out_group( $group, $ms ); Fades out the channels by the given group id. The fade-out-time is specified by $ms. Returns the number of affected channels. halt_group SDL::Mixer::Groups::hals_group( $group ); Halts the channels by the given group id. Returns 0. AUTHORS
