Portcullis — Dungeon Mechanisms: Doors, Chests, Levers, Traps
A sound effect pack from Core Systems Asset Factory. Genre: Role Playing. Paid.
Portcullis — Dungeon Mechanisms: Doors, Chests, Levers, Traps is a sound effect pack, paid.
Every mechanism in this pack ships its whole lifecycle. Not one "door open" one-shot — a handle, a start, a swing that loops for as long as your animation runs, a stop, a slam, and a rattle when it is locked. 105 states across 24 mechanisms. Royalty-free for commercial use in unlimited games, on any engine, forever. No attribution required. No per-title fee.
You may ship these sounds in as many commercial projects as you like, including paid ones. The only thing you may not do is resell or redistribute the pack itself as a sound library. The full plain-language licence is in the download, and it is short. Why the loops matter 22 of the 123 files are real loops with sample-accurate loop points, and they exist for one reason: the middle of an animation has no fixed length.
If your portcullis takes 1.4 seconds to rise on one map and 3 seconds on another, a one-shot cannot score either of them — you cut it off or you leave silence. Here you play start, loop move for exactly as long as the thing is moving, then play stop. Every loop was checked mechanically at the wrap for a click, for a level pump, and for a fade across its own length.
