The Standard Plats Starting At The Top (2 types) - from the QuakeLab

The QuakeLab - http://www.in2nett.com/stevefu/QuakeLab

TEXTURES:

	No actual standard. 

ENTITIES:

        func_plat or func_door, func_plat, trigger_once and/or trigger_multi-
        ple

WHAT TO DO:

        Type 1: Plat starts at top, player walks onto it, goes down, goes up
        and down until player gets off, plat ends up at bottom and waits
        there. Same as E1M3.

        Make a brush and place it at it's starting position. Designate it a
        func_plat and give it a targetname. Make a brush of the same size,
        place it where the plat is or just above the plat, and make it a
        trigger_once targeting the plat. This makes the plat start at the top.
        Then set the plat_low_trigger flag for the plat to the 'on' position.
        Set the height of the plat appropriately - see the standard plat
        if you don't understand this.

        Type 2: Plat starts at top, player walks onto it, goes down, plat
        goes back to top and waits at the top. Player can disembark, and if
        stuck at the bottom, can still trigger the plat to come back down.
        As per American McGee's response to Thred's webmaster.

        This is actually not a plat, but a func_door. Make your flat brush
        and call it a func_door instead of a func_plat. Give this 'doorplat'
        a negative lip which will basically be the equivalent of the height
        for a plat. and an angle of -2 (ie: make the door go down.) Give this
        'doorplat' a targetname. Make a trigger_once (same size as the
        'doorplat') and place it just above the 'doorplat', targeting same.
        Make another trigger of the same size, but call it a trigger_multiple,
        and put it at the bottom destination of the 'doorplat'. This allows
        people to recall the plat from below when they walk under the
        'doorplat'.

OPTIONS:
        sounds, wait, dmg, and speed for the func_door 'plat' can be adjusted.
        In the example file, I've set the dmg to 600 (enough to kill a Sham-
        bler) so don't loiter under the 'plat'! I think you can always set
        messages for the various triggers to print out when they are set off.
        Experiment with the shapes and designs of these plats.
