    I would like to make a brush, or something that acts like a brush that.
    -does collide when standing on top of it
    -does not collide when you touch it from the side or bottom

    I would like to make little platforms for a super smash brothers styled map.


    Also (unrelated to the previous question)
    since the update, TF2 crashes when trying to create a server. right at the beginning of the progress bar, no weird error messages, just "hl2.exe has stopped working", I'm using windows 7 RC btw. anybody else have this problem?

    using a dedicated server works, but its annoying

    I'm not aware of a brush that would do that. You could emulate it with doors and triggers, but the person on top would still fall through when the person on the bottom tried to go upwards...

    Maybe some variations on trigger_push or trigger_gravity could work?

    _______-

    For the crashes, uninstall or disable Sourcemod (I renamed the "addons" folder) because it's incompatible with the new version.

    I'll experiment a bit.

    Wow, you figured out quickly that I had sourcemod

    You could try a dispacement displaced on the top, not bottom and then a trigger push 1 unti think pushing you up. If you want a texture on the bottom, then add a func_illusionary.

    I tried it withouth the push, but you just fall through.

    I found something out. Normally you can't go through the other side of displacements (its like an invisible wall) but if you're underwater, you can. Maybe put a small bit of water under a displacement?

    perhaps ontouch trigger brushes where you could disable the collision brush, and when you are not touching them, it goes back to normal...but then you run into the problem if two people are touching it.
