Re: Does anyone still want a proper elevator?
That method will work far better for feet, and well for going down, but everything else going up...
I'm predicting a rough ride.
Edit: Actually, after a bit of testing, adding terrain under stuff doesn't work for rising at all really. At a rise of 1 m/s, a pretty slow elevator speed, you have to continuously walk back and forth to not sink into the floor. At even 0.1m/s, you eventually sink into the floor if you don't walk around a bit. I don't think this could be well compensated for with adding backup MO-MO collisions.
You could improve on my testing method, I'm sure, but it's such a failure that I would consider it a debunking of the method, for rising.
Removing terrain from below something works perfectly fine for descending, but it gets a little bouncy at high speeds.
Replacing your collision system with a plain terrain floor while it's stationary could be good, though.
