What it does:

• Right-click to talk — Dialogs trigger when a player right-clicks the entity.
• Works on custom entities — Attach a dialog to any mob, including ones with custom names, NBT, and data. The entity's normal right-click behavior (like villager trading) is automatically suppressed so the dialog always takes priority.
• Lines, your way — Add, insert, reorder, recolor, edit, and remove lines freely. Color a whole line, a single word, or set a default color for new lines.
• Mention the player — Drop the clicking player's name right into a line (e.g. "Welcome, Steve!").
• Named speakers — Give the talker a name with its own color (no forced bold).
• Timed pacing — A configurable delay between lines (default 3 seconds) makes conversations feel natural. The entity locks during playback so it can't be spam-clicked.
• Audible dialogs — Attach a sound or a group of sounds; one plays at random with each line.
• Broadcast range — Keep a dialog private to the clicker, or set a range so nearby players all see it.
• Play-once dialogs — Mark a dialog to play fully just once; afterward, clicking only replays the final line. Reset it anytime to play in full again.
• Full command-block control — Lock and unlock dialogs, swap an entity's current dialog for a new one, force-play to a player, and react to completion.
