Threshold is an RPG Maker MZ plugin that animates doors without door sprite sheets. Stock MZ needs a hand drawn character sheet for every door style, and a custom tileset usually has none.
You give an event your own door tile as its graphic and write a note tag like <threshold: door>. When the map loads, Threshold reads that tile once and draws its opening from the tile’s own pixels. There are eight kinds: a hinged door that swings and shows its edge, double doors, a portcullis that rises in steps, a floor hatch, a sliding shoji, a curtain, a round vault door and a cave mouth that gets depth and cold air. Closed, the door shows your tile exactly.
There are no images to install. The code was written with AI. It’s $11.99.
