Non-solid 3D Floor from below, solid from the top

[Guest]

How can I make a sector set 3d floor a non-solid from the bottom, but have a solid floor?
As in you could jump through it from the bottom, and then stand on it. I thought of making it a swimmable 3d floor so you could jump through it, and making the player be able to walk on water, but that doesn't seem to be a thing

sorry for the dumb question lol

This cannot be done because movement direction is not being considered when doing collision detection. Either something is solid or it isn't.

I suppose you might try to simulate it by doing something like having a script that monitors the player's position and z-height and when they go above a certain height (i.e. have moved up through a non-solid 3D floor) very rapidly move up a second invisible, solid 3D floor below them. So it would look like they were standing on the non-solid one but they would actually be standing on the newly risen invisible solid one.

Of course, such a setup would only work in certain situations and might be easy to break.
