simple elevators

i need a simple elevator that simply goes up when you stand on it (down
if you're under it) and then moves back to its original position after
a certain amount of time, i sort of remember that there was i func_plat
in hl1 or something, but how do i make it in hl2?

My advice is to always look at the tutorial section first, if you find
one there try it. If you still have questions post it here, or in the
tutorials comment section. A great tutorial, and you can download a
support map file is right here at snarkpit

yeah its a great tut and stuff, but, just want a flat shaped
square thing in my map without any buttons or doors or something like
that, just a flat thing that goes up and down

well you can have a func_train that is activated by touch, or a func_door that goes up that is activated by touch...

Follow the tutorial on how to set up the platform but instead of having a button or whatever trigger it use a trigger_multiple and place it so the player has to be completely on the platform before it can be triggered.

thanks i will try that, my map is no so fun if you cant go to the "combine stuff" level
