PuzzlesAndDoors

The Door Creator Tool now keeps the active selection outlined until you finish or walk away, instead of flashing once and vanishing. The outline redraws every 6 ticks with a 0.5s particle lifetime, so it reads as continuous rather than pulsing.

• Four colour-coded highlight states:
  • magenta — corner A placed, waiting on corner B
  • cyan — selection is valid
  • red — selection is rejected (not one block thick, or outside the 2–64 block range)
  • amber — aiming the tool at an already-registered door outlines that door
• /scriptevent puzzles:highlight [on|off] toggles the highlight per player. Omitting the argument flips the current state.
• functions/puzzles/highlight.mcfunction as a shorthand for the toggle.
• Four custom particles in the resource pack (select_edge, select_corner, select_invalid, select_door) sharing one tinted 16×16 texture at textures/particle/puzzles_select.png.
