ServerSideBuilds v2.1.0 Changelog

Welcome to the ultimate release of ServerSideBuilds! This update introduces a brand-new Interactive Build Mode, native client-side glowing block projections, advanced transformations, and extensive security and stability improvements.

New Features

Interactive Build Mode (/ssb buildmode / /ssb bm)

• No more typing tedious commands! Entering Build Mode saves your survival inventory and replaces your hotbar with custom interactive tools:
  • Rotate 90° (Right-click to rotate the blueprint horizontally)
  • Mirror X (Right-click to mirror horizontally | Left-click to mirror vertically)
  • Mirror Z (Right-click to mirror Z | Left-click to reset transformations)
  • Nudge (Right-click to shift in your facing direction | Left-click to nudge up)
  • Layer Up (Right-click to view the next blueprint layer up)
  • Layer Down (Right-click to view the next layer down | Left-click to show all)
  • Paste All (Instantly paste the entire blueprint; Creative/OP only)
  • Fill (Automatically place matching blocks from your saved survival inventory)
  • Exit Build Mode (Safely restores your saved survival inventory)

Holographic Glowing Blocks (BlockDisplay System)

• Replaced packet-based block changes with Minecraft's native BlockDisplay entities.
• Holograms now feature a client-side glowing outline showing exactly where blocks need to be placed.
• Hologram blocks have no collision, allowing players to walk straight through them to build.
• Spawning is limited to a 20-block radius around the player to maximize performance.

Advanced Mirrors & Rotations

• Mirror Y (Vertical Mirror): Mirroring vertically now swaps properties for vertical slabs, stairs, trapdoors, pointed dripstones, button/lever placement faces, and lanterns.
• Connection Rotations: Fences, walls, glass panes, and redstone wire properties now update and link accurately when rotated or mirrored.

Raytrace-First Auto-Material Switcher

• Automatically equips the correct block type from your inventory when right-clicking an unplaced hologram block with an empty hand.
• Uses a 5-block line-of-sight raycast first, detecting hologram blocks even when pointing at solid blocks behind or underneath them.

Materials Checklist Command (/ssb materials)

• View a sorted list of the remaining blocks needed to complete the active projection directly in your chat.

Security, Exploits & Bug Fixes

Inventory Safeguards

• Clear & Re-Project Fix: Fixed a bug where re-projecting or running /ssb clear while in Build Mode deleted the player's saved inventory. The plugin now automatically restores inventories first.
• Reload & Shutdown Restores: Added a shutdown sequence that restores all online player inventories before the plugin unloads.
• Death & Respawn Fixes:
  • If keepInventory is false, your real saved inventory drops on the ground, and build tools are discarded.
  • If keepInventory is true, build tools are automatically replaced by your saved inventory so you respawn with your real items.

Container & Drag Exploits Prevention

• Blocked keyboard hotbar key swaps (1-9) involving build mode items to prevent players from transferring tools into chests.
• Blocked dragging or distributing build mode items inside chest, dispenser, or hopper interfaces.

Performance & Leak Optimizations

• No Stranded Entities: Set BlockDisplay entities to non-persistent so they are never saved to world data, avoiding permanent orphaned ghost blocks on crashes.
• Memory Safety checks: Pre-validate schematic volume to prevent OutOfMemoryError before allocating memory.
• Asynchronous Disk I/O: Dispatched save and import commands to async threads to eliminate server tick lag.
• Selections Memory Leak: Cleared stored corner coordinates on player logout.
