Block Traits: connection

The minecraft:connection block trait contains information about whether the block connects to other blocks, and if so, on what faces. The values of the states will change when the block or neighboring blocks change or move.

Important

The connection trait requires Bedrock Edition 1.21.130 or higher, and currently requires that the "Upcoming Creator Features" experimental toggle is set on.

There is only one valid state for enabled_states in this trait: minecraft:cardinal_connections.

Queryable block states

When the cardinal_connections state is enabled, you can read one of four block states for connections.

• minecraft:connection_north is true if the block is connected to another block to the north, false if it is not.
• minecraft:connection_south is true if the block is connected to another block to the south, false if it is not.
• minecraft:connection_east is true if the block is connected to another block to the east, false if it is not.
• minecraft:connection_west is true if the block is connected to another block to the west, false if it is not.
