local-multiplayer 1.2.0 — Minecraft 26.3

Release build: 2026-11-08. Minecraft and NeoForge dependency ranges are [26,27). The verified baseline is Minecraft 26.3 / NeoForge 26.3.0.77; other 26.x combinations remain unverified.

Changes

• Route nearby world and entity sounds to guests, including creature ambience, damage and attack sounds, while suppressing broadcasts already received by the primary connection.
• Adjust primary controller look timing and guest sleep interpolation; unrelated stick drift no longer blocks sleep or death confirmation.
• Restore vanilla block outlines in guest viewports.
• Integrate Controllable swap-hands binding, directional menu navigation, and per-viewport controller prompts and paper dolls.

Installation and verification

Install local-multiplayer-neoforge-26.3-1.2.0.jar in the 26.3 NeoForge instance's mods folder and remove the older version. Controllers use Controllable 0.26.2 / Framework 0.13.27; Java 25. Existing configuration and player data are retained.

The user confirmed guest sleep, waking and sleep display using one XInput controller, and confirmed guest block outlines. Programmatic checks cover guest sound submission, actions and menu input. Actual listening, primary controller look, guest prompts and personal-container navigation, and simultaneous physical controllers remain unverified. The reported controller use-button issue has not been diagnosed and is not claimed fixed. Stop-sound packets, block level-event sounds and independent listeners remain outstanding.

Known issues and troubleshooting

• Third-party interactions: A report says Player 2 cannot use certain Skywyrms dragon abilities or see their duration indicator, and Zoomify may zoom both viewports together. These compatibility issues remain unresolved and their causes are unknown.
• Item and block synchronization: A report describes thrown items temporarily disappearing, placed or broken blocks flickering, disappearing or updating late, and inventory items taking minutes to return. These symptoms have not been diagnosed or confirmed fixed.
• Controllers and sound: The reported controller use-button issue is not confirmed fixed; swap hands, prompts and navigation need further physical-device checks. Guest mob and attack sound handling has changed, but actual listening remains unverified. The effect of the Player 1 controller camera adjustment also remains unverified.
• Cross-dimension play: The user reported trying the Overworld and Nether; the End and long-term stability remain unverified.

If an unresolved issue occurs, try reproducing it in a backed-up test instance with other third-party mods temporarily disabled. Keep Controllable and its required dependencies when testing a controller. To investigate Skywyrms or Zoomify specifically, first keep the relevant mod and its required dependencies, then restore other mods gradually. This helps narrow down the cause; it does not establish that a third-party mod caused the problem.
