ServerSideBuilds Plugin

<h1>ServerSideBuilds v2.1.0 Changelog</h1> <p>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.</p> <h2>New Features</h2> <h3>Interactive Build Mode (/ssb buildmode / /ssb bm)</h3> <ul> <li>No more typing tedious commands! Entering Build Mode saves your survival inventory and replaces your hotbar with custom interactive tools: <ul> <li><strong>Rotate 90°</strong> (Right-click to rotate the blueprint horizontally)</li> <li><strong>Mirror X</strong> (Right-click to mirror horizontally | Left-click to mirror vertically)</li> <li><strong>Mirror Z</strong> (Right-click to mirror Z | Left-click to reset transformations)</li> <li><strong>Nudge</strong> (Right-click to shift in your facing direction | Left-click to nudge up)</li> <li><strong>Layer Up</strong> (Right-click to view the next blueprint layer up)</li> <li><strong>Layer Down</strong> (Right-click to view the next layer down | Left-click to show all)</li> <li><strong>Paste All</strong> (Instantly paste the entire blueprint; Creative/OP only)</li> <li><strong>Fill</strong> (Automatically place matching blocks from your saved survival inventory)</li> <li><strong>Exit Build Mode</strong> (Safely restores your saved survival inventory)</li> </ul> </li> </ul> <h3>Holographic Glowing Blocks (BlockDisplay System)</h3> <ul> <li>Replaced packet-based block changes with Minecraft's native BlockDisplay entities.</li> <li>Holograms now feature a client-side glowing outline showing exactly where blocks need to be placed.</li> <li>Hologram blocks have no collision, allowing players to walk straight through them to build.</li> <li>Spawning is limited to a 20-block radius around the player to maximize performance.</li> </ul> <h3>Advanced Mirrors & Rotations</h3> <ul> <li><strong>Mirror Y (Vertical Mirror)</strong>: Mirroring vertically now swaps properties for vertical slabs, stairs, trapdoors, pointed dripstones, button/lever placement faces, and lanterns.</li> <li><strong>Connection Rotations</strong>: Fences, walls, glass panes, and redstone wire properties now update and link accurately when rotated or mirrored.</li> </ul> <h3>Raytrace-First Auto-Material Switcher</h3> <ul> <li>Automatically equips the correct block type from your inventory when right-clicking an unplaced hologram block with an empty hand.</li> <li>Uses a 5-block line-of-sight raycast first, detecting hologram blocks even when pointing at solid blocks behind or underneath them.</li> </ul> <h3>Materials Checklist Command (/ssb materials)</h3> <ul> <li>View a sorted list of the remaining blocks needed to complete the active projection directly in your chat.</li> </ul> <h2>Security, Exploits & Bug Fixes</h2> <h3>Inventory Safeguards</h3> <ul> <li><strong>Clear & Re-Project Fix</strong>: 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.</li> <li><strong>Reload & Shutdown Restores</strong>: Added a shutdown sequence that restores all online player inventories before the plugin unloads.</li> <li><strong>Death & Respawn Fixes</strong>: <ul> <li>If <em>keepInventory</em> is false, your real saved inventory drops on the ground, and build tools are discarded.</li> <li>If <em>keepInventory</em> is true, build tools are automatically replaced by your saved inventory so you respawn with your real items.</li> </ul> </li> </ul> <h3>Container & Drag Exploits Prevention</h3> <ul> <li>Blocked keyboard hotbar key swaps (1-9) involving build mode items to prevent players from transferring tools into chests.</li> <li>Blocked dragging or distributing build mode items inside chest, dispenser, or hopper interfaces.</li> </ul> <h3>Performance & Leak Optimizations</h3> <ul> <li><strong>No Stranded Entities</strong>: Set BlockDisplay entities to non-persistent so they are never saved to world data, avoiding permanent orphaned ghost blocks on crashes.</li> <li><strong>Memory Safety checks</strong>: Pre-validate schematic volume to prevent OutOfMemoryError before allocating memory.</li> <li><strong>Asynchronous Disk I/O</strong>: Dispatched save and import commands to async threads to eliminate server tick lag.</li> <li><strong>Selections Memory Leak</strong>: Cleared stored corner coordinates on player logout.</li> </ul>
