V8.16.0

Features

• #526: Added the Portal Gun and Portal Surface system.
  • Portal Gun: A new item (enchanted shears) that can be obtained from a Mirror Chest. Left click places a blue portal, right click places an orange portal.
  • Portal Surface: A new placeable block (quartz block) that serves as a valid surface for portal placement. Available in the component selector menu.
  • Mirror Chest Portal Gun toggle: Mirror Chests can now optionally contain a Portal Gun. A new toggle in the content editor menu lets puzzle creators enable or disable it.
  • Portal placement: Ray tracing from the player's eye detects Portal Surfaces within 75 blocks. Portals are rendered as ~8 BlockDisplay entities forming an elliptical shape (1.8×0.8 blocks). Automatic clamping adjusts placement near surface edges, and overlap with existing portals is prevented.
  • Multi-player color pairs: Each player is assigned a unique color pair (up to 6 players per area) so portals are visually distinguishable.
  • Player teleportation: Walking through a portal teleports the player to the linked portal while conserving momentum (speed and direction are transformed based on portal orientations). Anti-bounce protection uses a hybrid approach (temporal cooldown + positional immunity).
  • Laser teleportation: Lasers entering a portal are teleported to the linked portal, preserving color, light level, and direction (transformed to match exit orientation). Infinite laser loops between facing portals are naturally bounded.
  • Portal lifecycle: Portals are automatically destroyed when the player leaves the area, disconnects, loses the Portal Gun, or when the surface/front blocks are broken or obstructed. Area reset clears all portals.
  • Sound effects: Distinct sounds for portal portal creation (fail or success), and player teleportation.
  • Custom events: BeforePlayerPortalTeleportEvent (cancellable) and AfterPlayerPortalTeleportEvent (informational) for third-party plugin integration.
  • Component Selection: Reorganized the component selector menu into a 4×9 layout.

Fixes

• #534: Fixed duration-based leaderboards (total time spent, record duration, first run won duration) being incorrectly sorted.
