Half-Life Prefab: Escalators
----------------------------
 by Manoj "Yumpee" Plakal <plakal@hotmail.com>, 30 Dec 1998

 - Escalators (both up and down): brown metal steps, silver metal casing,
   black railing
 - textures (brown:generic015t, silver:generic028 and black:black): these don't get 
   screwed up when you copy/move the prefab around

 - solids: 94, faces: 510, entities: 49 (25 point + 23 solid)
 - Editor: WorldCraft 2.0
 - Time to build: Around 4 hours (those damned curves!!)

 - Credits:
    - Inspired by Dave "DEFusion" DaSpurr's escalator prefab for
      Quake2 (http://www.daspurr.freeserve.co.uk). I got the idea
      of how to model the escalator with func_train entities from
      Dave's prefab, but I made this Half-Life prefab from scratch.
 
 - Usage:
    - The way it works is simple: the escalator consists of 22 steps,
      each step is a func_train. I also have a path of 22 path_corners
      and the func_trains move on this path. The whole thing is
      triggered by a multi_manager which triggers the escalator
      noise and two other multi_managers which trigger the top and
      bottom 11 steps. There is also a trigger_push at the end of
      the escalator which pushes you off the escalator.
    - To use: simply make a trigger_auto in your level target
      the top-level multi-manager (esc_boss_mgr or esc_dn_boss_mgr
      for the up and down escalator, respectively) and this will
      start the escalator. See the sample map provided.

  - Warnings:
    - If you run up or down the escalator, you might get hurt 
      now and then and even obstruct some steps, producing ugly
      gaps in the escalator :( 

    - When copying/moving the prefab around, make sure the
      angle of the trigger_push at the end of the escalator is pointing
      towards the correct direction.

    - Some names are used by the entities in the prefab: The up
      escalator uses esc_boss_mgr, esc_mgr1, esc_mgr2, esc_noise,
      step1-20,step10a,step20a, esc1-20, esc10a, esc20a. The down
      escalator uses the same names with _dn_ inserted in the middle
      e.g., esc_dn_mgr1, step_dn_20 etc. 
      Make sure these names don't clash with names of entities in
      your level. Also, you will have to do some renaming if
      you want more than 1 copy of the up and down escalators in one
      level. The easiest way to do this renaming is to open up
      a map file containing the prefab in a text editor and doing
      a search and replace for the esc_* and step_* words. 

 - Legalese: you are free to copy/modify/use in your own maps (would 
   be nice if you mentioned where you got the prefab from). You are
   NOT allowed to re-distribute the prefab in any way without 
   permission of author.
