Portal Gun (revived)

v5.2 - Bigger, Twistier Test Chambers

• Rooms vary in size. Every chamber gets its own length, width and ceiling height.
• Dungeons turn. The exit door can be on the far wall, the left wall or the right wall, so no two dungeons have the same shape.
• Side rooms. Some chambers have a side room that holds part of the puzzle. Some are walk-in, others sit behind a window that only a portal gets you through.
• Difficulty ramps up about 25% per room. Later rooms combine ledges, pits, faith plates, extra buttons and more turrets.
• Dungeons are fully protected. Walls, doors, floor buttons, faith plates and ladders inside a dungeon cannot be mined, blown up, pushed by pistons or picked up with the gun.
• The light mast on top of the entrance building is gone.

v5.1 - Fixes

• Fixed being shoved through the wrong portal when two portals sit on two faces of the same corner block.
• Portal shots now pass through glass, stained glass, glass panes and iron bars.
• Fixed double shots: both triggers share one short cooldown.
• Dungeon entrances are more common in newly generated chunks.
• New command /portalgun locate prints the nearest dungeon entrance.

Requires Fabric API. Only newly generated chunks get dungeon entrances.
