Creating CTF Levels

This tutorial will show the basics of  making
a  CTF  level  and  using  team  gameplay.

I've  created  a  basic  CTF  layout  with  a  spawining room
with  a  small   connecting  hallway  to  an  adjoining   room
for  the  red  team.   Traditionally most CTF maps will have
a  mirrored  layout  so   that  both   teams  have   the  same
access  to  entry  and  exit  pathways  along   with  weapon
choice.   With this in mind the easiest way to design your
map  is  to  think  of  the  level  as  two  identical sides that
face  eachother.    Once  one  side is finished simply draw
a  brush  that  will  surround  the  entire map and use the 
"select inside" button on  the  toolbar.  This will select all
brushes within and discard the original selecting brush.


   

Now  with  your  level  selected  just clone the selected brushes
by  hitting  the  space  bar  and  rotate the cloned selection with
the   "z-axis rotate"   button  and  line up your new creation with
the  other  side  so  that  it  matches  perfectly.    Now in my little
example  I've  just  made a small connecting brush to bring the
two together but obviously most maps will have a central area
that  will  be  much  more complex.   Once you've united the two
sides  it's  time  to start placing our team entities.  The first that
we'll  throw  in will be both of the team flags.  With this map the 
location  will   be   at   the   end  of   the  opposing  spawn  rooms. 
Simply  right-click on the  2-D  veiw and select "team" and then
"team_CTF_redflag" and position the entity at the center of the
red  team's  spawning  area.   Now  do the exact same thing with
the  blue  team's  side  but select "team_CTF_blueflag" instead.

    


Remember that with all of the entities that we'll be placing
within the map they each have an arrow indicating which
direction the the player will spawn including the flags. You
can  edit  the  direction  of  the  arrow  by hitting the "n" key 
with the  entity  selected  and  bring  up  the  entity  window.
At  the  bottom  left  of  the  window  you'll  see  a  set of keys
with  270, 180, 360, ect.   These  just indicate which way the
arrow  will  point.   Look  at  your entity and  hit  the  buttons
until  the  arrow  points  in the direction you'd like. Now it's 
time  to  place  the  individual  team  entites  so  onwards!
