getDataAsXy static method

List<int> getDataAsXy(String entertainmentConfigurationId, List<EntertainmentStreamCommand> commands)

Creates a packet to send to the bridge, using XY+brightness color space encoding.

The entertainmentConfigurationId parameter is the ID of the entertainment configuration to send the data to.

The channels are the channels that are having their colors set, and what color they are being set to. Note, any channel that is using RGB instead of XY will be ignored.

Returns a list of bytes representing the packet.

Implementation

static List<int> getDataAsXy(
  String entertainmentConfigurationId,
  List<EntertainmentStreamCommand> commands,
) {
  final List<int> packet =
      _getPacketBase(ColorMode.xy, entertainmentConfigurationId);

  // Add every command to the packet.
  int counter = 0;
  for (final EntertainmentStreamCommand command in commands) {
    // Skip any commands that are not using XY color space.
    if (command.color is! ColorXy) continue;

    // Only allow 20 commands per packet.
    if (counter >= 20) break;

    packet.add(command.channel);

    packet.addAll(
      _formatXy(
        (command.color as ColorXy).x,
        (command.color as ColorXy).y,
        (command.color as ColorXy).brightness,
      ),
    );

    counter++;
  }

  return packet;
