Panning Platform Engine
An excellent engine. I tried to decypher the code but it's really dense, it's no wonder zzt has to be turned up to its highest speed setting, and even still it's choppy. As cool as it is, there are some drawbacks. Nothing outside of the player can move in the engine, and I don't see how shooting would be possible with it. Still there's no faulting the ingenuity of the engine.
It'd be cool to see something like it in szzt, (using the visible area as the display for the engine and the rest of the board as the map) but with the lack of speed settings in szzt, the code would have to be really tight or changed entirely.
Overall a zzt programming marvel.
Good points: This is a well-implemented and bugless true side-scrolling engine for ZZT! It is better than my sidescroller in that it scrolls in all 4 directions and manipulates a persistent world.
Bad Points: slowest engine ever made for ZZT. Use of invisibles severely narrows the potential scope of the project.
Retrospect: best engine for ZZT ever. I would love to see a plastic version, which could have a much wider variety of terrain types and would run real-time using #look.
