I don't know the script you're referring to. From the sound of it, though, I'm guessing you can have multiple ladders, but each needs its own FFC. I'd guess you can span screens by having one on each screen.
If it doesn't work out, I doubt it would be hard to fix it or write another.
Depending on what exactly you want to do with it, it should be possible. The biggest problem with scrolling is that there's no good way to make enemies recognize what should be solid, so walking enemies just won't work right. Aside from that, you can probably make it work, but it won't be easy.Hmm. Okay, I asked about ladders, and moving platforms, so... Oh, my next question, is can you have an "auto scroll" level? Here's how I would like it to look, and hopefully this will help get a more accurate answer. Basically, Link, and the platform stay stationary in the center of the screen, and the surrounding "level" and obstacles moves to the left. I doubt this would be an easy thing to implement, since the solid "level" would need to be updated every frame or something. This would probably cause major lag.
Nope. You could, however, just set up video frames in your tiles and draw them with DrawTile. The number of frames would be very limited, but it's about the best you can do.Lastly, and least likely to even materialize, is it possible to have ZC "play" pre-rendered video clips through some sort of "play-> file" command? I know it probably have to be within ZC's resolution and palette limits and all that. I feel stupid just asking since this one is probably so absurd, but I figured, if it is possible, it would be nice to know.
