BlockShips

New Features

Wider Minecraft Version Support (1.20.1 - 1.21.11, purpur support)

• New compatibility layer supports Minecraft 1.20.1 through 1.21.11+
• purpur support
• Pre-1.21.2: Uses S+Space for airship descent (sprint unavailable in packet)

Better ship collider handling

• standing on ship decks works more reliably, no longer bugs out as much

/blockships dismount Command

• New command allows players to force-dismount from ships when normal methods fail
• Permission: blockships.dismount (default: true)

Health Regeneration Enabled by Default

• All ship types now regenerate 1.0 HP/second by default (was 0.0)
• Applies to: galley, airship, skiff, and custom ships

Performance & Stability Improvements

• Reduced GC pressure via object pooling (33+ reusable work objects)
• Async I/O for ship recovery prevents main thread blocking during chunk loads
• Thread-safe steering packet handling with cached reflection methods
• Early termination in terrain collision detection

Bug Fixes

Sneak-to-Dismount for Shulker Seats

• Fixed sneak (shift) dismount for Shulker seats across all Minecraft versions
• Version-specific packet handling for 1.21.2+ and 1.21.3+ formats
• Applies to all ship passengers, not just the driver

Ship Entity Persistence on Player Disconnect

• New PlayerQuitEvent and PlayerKickEvent handlers
• Ejects player from ship seat before disconnect completes
• Prevents vanilla Minecraft from removing ridden entities
• Properly frees seat for other players

Dismount Re-mount Prevention

• Fixed: Players being forced back into seats after intentional dismount
• updateCollisionPositions() now checks occupiedSeatIndices before re-mounting
• freeSeat() removes seat from occupied set, preventing re-mount

Input State Cleanup on Driver Exit

• freeSeat() now clears ALL input flags when driver exits
• Prevents ships from continuing movement with stale input state
• Airships get currentYVelocity = 0; water ships snap to neutral buoyancy

Passenger Relationship Verification

• Added every-tick check that shulker is still passenger of carrier
• Fixes broken relationships on chunk reload
• Re-adds passenger if relationship breaks (even on stationary ships)

Collision Shulker Spawn Error Handling

• Wrapped collider spawn in try-catch blocks
• Cleans up dangling carriers/shulkers on failure
• Prevents resource leaks and NPEs during configuration

Attribute Compatibility Fixes

• MAX_HEALTH and SCALE access wrapped with null checks
• Health regeneration wrapped in try-catch to prevent tick crashes
• Graceful degradation if scale attribute unavailable (pre-1.20.5)

Pre-1.21.9 Display Rotation Fix

• Added spawnYaw tracking for display rotation compatibility
• Prevents double-rotation bug on older versions
• Display rotation uses delta from spawn instead of absolute yaw

Removed Non-functional Deck Physics

• Deleted applyDeckPhysics() and pushPlayerOutOfShulker() methods
• These caused buggy movements on ships, and were non-functional, removed them
