require "entity"

-- An editor annotation dropped onto the grid. A Note is a normal Entity (so it
-- serializes, places and hit-tests like any other object) that carries a bit of
-- author text. It is deliberately non-collidable — the player passes straight
-- through it — and only ever renders as a translucent icon while the editor is
-- available (DEBUG) and notes are toggled on (see NOTES_VISIBLE / Room:draw).
Note = class("Note", Entity)

local noteSprite = loadSprite("art/_debug/notepad.png")

function Note:initialize(x, y, text)
	self.text = text or ""
	self.saveClass = "note"
	Entity.initialize(self, {
		x = x, y = y,
		color = "white",   -- representative only; Note:draw ignores channels
		collision = "none",
		sprite = noteSprite,
	})
end

-- Drawn once (not per-channel) as a faint overlay. Called directly from the
-- room's note pass, so it takes no channel argument.
