Multiple Floors

Any way to make a building with 2 floors have both floors be walkable?

hard but possible

easy... not only 2... you can have multiple floors

Care to elaborate? Your post dosen't exactly help the OP.

Yes and no, you can simulate multiple floors with some complex destructable stuff for 1 player, but if you put more than 1 player into the mix or units that move around the building then WCIII goes NO FUCK U.

Toadcop does it with his shooter map. I think his has something to do with a physics engine, and then creating an "object" that acts like a solid surface for the engine.

You can also simulate it with flying heights. Just make it so when the unit leaves the stairs or w/e, set its flying height to the height of the floor.
