Structure Roads

0.6.1 — Road Starter and structure activation

• New craftable Road Starter: 1 lantern + 1 stick + 1 stone or cobblestone, in any arrangement.
• Place it on solid ground: it becomes a normal lantern and queues a road toward a nearby completed road. Without a suitable nearby road, it starts a 96-block segment.
• Placement re-enables automatic planning, retries eligible failed jobs and unresolved entrances, and requests entrances for up to 16 nearby discovered structures without built connections, within 1536 blocks.
• Temporarily accelerates planning for 16 rounds. Terrain construction retains its existing limits and protection checks.
• Ordinary lanterns do not activate roads. Mining the placed starter returns a normal lantern, preventing starter duplication.
• Includes 0.5.1 junction fixes, independent exits when structure attachments fail, and the one-time retry of older rejected routes.
• Junction lighting may reuse an existing nearby lantern rather than block a connection.

Validation

Native Forge 1.20.1 / 47.4.10 tests passed for crafting with both stone and cobblestone, missing ingredients, floor placement and consumption, normal lantern drops, vanilla lantern behavior, pending work reactivation and the temporary planning boost. The new branch physically joined an existing road. Horse movement, support and collision checks passed at 227 positions across the baseline, new connection and reactivated job; the no-nearby-road starter passed another 97 positions.

Experimental limits

Only discovered structures are considered; not every structure can be connected safely. Placement queues bounded work rather than instantly building an entire world. Fully submerged entrances remain unvalidated. Back up your world before using this alpha.
