Cable Junction


Cable Junctions are blocks that can be connected to each other via a Bundled Cable Spool to transmit redstone power on multiple channels across long distances.

Usage

Cable Junctions can be placed in 6 different orientations, on walls, floors, and ceilings. When placing the block, the flat side will be placed against the face clicked by the player.

Cable Junctions can be connected to other Cable Junctions or to Cable Relays by using a Bundled Cable Spool on two such blocks. Connections can be removed by using the spool on the two connected blocks again.

Cable Junctions can connect to Colored Cables and Bundled Cables to transmit signals on specific color-channels. They can also connect to Red Alloy Wires, in which case signals will be transmitted on all sixteen channels.

Blockstate PropertiesValuesDescription

transform{"identity", "rot_180_face_xz", "rot_90_y_neg", "rot_80_y_pos", "invert_x", "invert_z", "swap_xz", "swap_neg_xz"}Set when the block is rotated/mirrored by structure generation or similar mechanics; it ensures positional blockentity data is transformed accordingly. When placed by a player, this will always be "identity".

History

VersionChangelog
1.21.3-7.0.0.0
  • Rewrote how wires connect and transmit power; all wires in a network update at once instead of causing cascading block updates
  • Renamed from Bundled Cable Relay Plate to Cable Junction (bundled_cable_relay_plate -> cable_junction
  • No longer stores power
  • No longer loses power over distance; instead has a maximum network size (default 1024, configurable)
1.20.1-4.0.0.0
  • Added transform blockstate property
  • connections are now stored as relative positions instead of absolute positions
1.16.5-2.1.0.0Added to game
