(Lazyness took me again and Botman is better than me in explaining things)

* V1.2 Waypoint Makers please read:

If you previously did some waypoints for POD-Bot you will notice some
differences. First, you are now allowed to have connections between
8 Waypoints at the same time (was 4 before). Also the Wayzone Radius
gets calculated instantly now when placing a waypoint (makes "wayzone
calcall" somewhat obsolete). And even more important you should now do
lots of waypoints since the Bots will try to to vary them. Also try to
place waypoints at Places where you would like them to take cover (see
below for a more lengthy explanation).


1. Waypoints, what are they?

Waypoints are locations in the maps that the bots will use when navigating.
They allow the bot to roam about the map without having to blindly bump into
walls.  Waypoints can be thought of like the bread crumbs in the Hansel and
Gretel story.  They are something marking a path to make it easier to follow.
The waypoints are not displayed while the game is being played.  The bots
"know" which way to go by following the path laid out by these waypoints.

In order to get the bots to cover the entire map when playing the game,
waypoints should be laid out all over the map.  Without the waypoints the
bots will just randomly run around and will tend to stay in the same area.
Waypoints also allow the bot to know where specific goals are in the game.
You couldn't play capture the flag unless you knew where the flag was and
where the flag needed to be taken after being captured.  Waypoints are what
makes all of these things possible.  Bots with sufficiently advanced waypoint
information and algorithms would be able to find the shortest distance
between points in the map and navigate from their current position to some
goal on the other side of the map.

This document describes the commands needed to create or edit a waypoint
file (to be used with the POD-Bot).  When creating or editing a waypoint
file it is best NOT to have any bots wandering around at the same time.
Create a LAN game, and join the game then start laying out waypoints for
a map.  Save the waypoint file, disconnect from the server, then start the
game again, this time with the bots to see how well (or poorly) they follow
the waypoints you have created.


2. What do waypoints look like in the map?

The waypoints are displayed using vertical lines that look like lightning or
electric streams.  The vertical line used to draw the waypoint is the same
height as the player.  The point in space at the center of this vertical line
is what is actually used as the waypoint. Different Types of waypoints have
different colors. 

Waypoints are stored in a file with the same name as the map file name but
using the extension ".pwf" instead of the map file extension of ".bsp".  For
example, the waypoint file for the map de_dust would be de_dust.pwf.It will be
stored in the Half-Life\cstrike\PODBot folder and then in the folder you specified
with wptfolder (defaults to "WPTCS10").
Waypoint files are automatically loaded when the map is loaded (if they
exist).  If the waypoint file does not exist, you will need to create it
using the directions contained in this document.


3. Waypoint console commands Summary

The following Waypoint commands are available (note these ARE case sensitive):

"waypoint on" - Turns on displaying of waypoints.
"waypoint on noclip" - Turns on waypoint editing with noclip cheat. This allows you
		       to fly and you don't collide with walls. Useful for doing swim
		       waypoints.
"waypoint off" - Turns off displaying of all waypoints.

"waypoint add" - Adds a waypoint at the current player location. A Menu will pop
                 up where you have to select the different types of waypoints
"waypoint delete" - Deletes the waypoint nearest to the player (see below).

"waypoint showflags" - Shows all of the Flags which are set manually on this waypoint
"waypoint addflag" - Allows you to manually add Flags to a waypoint.
			 
"waypoint delflag" - Let's you select a waypoint flag to delete

"waypoint setradius x" - Manually sets the Wayzone Radius for this waypoint to
			 Value x
			 
"waypoint stats" - Shows the number of different waypoints you did already set.

"waypoint check" - Checks if all Waypoints are valid

			 
"wayzone calcall" - Calculates the Wayzone Radius for all Waypoints in the Map. 

"waypoint save" - Saves the current waypoint list to a file (see below).
"waypoint load" - Loads the waypoint list from a waypoint file (see below).


"autowaypoint" - Displays the status of the autowaypoint setting.
"autowaypoint on" - Turns on autowaypoint setting (see below).
"autowaypoint off" - Turns off autowaypoint setting.

"pathwaypoint" - Displays the status of the pathwaypoint setting.
"pathwaypoint on" - Turns on the pathwaypoint setting (see below).
"pathwaypoint off" - Turns off the pathwaypoint setting.
"pathwaypoint add x" - Connects the nearest Waypoint to you, with the
		       waypoint whose number specified with Value x.
"pathwaypoint delete x" - Disconnects the nearest Waypoint to you, with the
		          waypoint whose number specified with Value x.
		       


To use the waypoint commands, you will have to use the console.  You must
start the game with the console option enabled (use "hl.exe -console" in
the Target: line of a shortcut or use "Half-Life Console" in your SIERRA
menu from the Windows Start button).  Use the '~' key to bring down the
console.  Enter the console commands that you wish, then use the '~' key
again to return to the game.

You can make things easier by binding console commands to keys on the
keyboard.  Just type "bind" followed by the key you want to bind to,
followed by the console command.  You will have to use double quotes
on the console command if it's more than one word.  Here's an example
of console commands that I use when editing waypoints...

bind a "waypoint add"
bind d "waypoint delete"
bind l "waypoint load"
bind w "waypoint save"

The 'a' key will manually add a waypoint.  The 'd' key will delete a waypoint.
The 'l' key will load the most recently saved waypoint file (useful if you
have added some waypoints but don't want to save them and want to go back to
the previously save waypoint list, sort of like an "undo").  The 'w' key (for
"write waypoints") will save the list of waypoints to the waypoint file.  I
tried using 's' (for "save waypoints"), but I kept hitting 's' by mistake when
I wanted to add or delete a waypoint.

Using "waypoint add" will place a waypoint at the location that the player is
currently at in a map.  Waypoints can be placed anywhere the player can go.
Waypoints can even be placed in mid-air (as long as the player can get to
that location).  One way to do this is by jumping or running off of a ledge
or cliff. When placing a waypoint, you will hear a sound to indicate that
the waypoint has been dropped (the sound is the same sound the crossbow bolt
makes when striking an wall).
You then have to specify the Type of waypoint you want to place here.

"Normal Waypoint" sets a Waypoint which is used for normal walking from one
point to each other. From V1.4 on you should place lots of them, since the
Bots use them for hiding and varying their paths. Color is green.

"Terrorist Important Waypoint" and "Counter Important Waypoint"
These are strategical waypoints for that team. Bots use these waypoints
to patrol the map. How they use this, heavily depends on the map type.
In a DE Map you should place a lot of Counter Waypoints around the
Bomb Plant Zone and only 2 or 3 strategical waypoints for Terrorists.
On a DE Map Counter Bots will most of the time pick a Counter Waypoint as
a destination and only sometimes pick a Terrorist waypoint. Terrorists
are allowed to pick any of them as a goal waypoint. This behaviour changes
with the maptype, in a CS map for example it is vice versa.
You NEED to have some of these, but don't place too many. Average count
for this is below 10 for each. Terrists WP Color is red, Counter Waypoints
are blue.
 
"Ladder Waypoint"
These need to be placed on a ladder if you want the Bots to climb it.
Set the bottom waypoint at a position where you're already "stuck" to the
ladder. At the top of the ladder you should place another ladder waypoint.
Set this at a position where you can hardly look ever the edge. If the ladder
is quite a long one, you might want to place another ladder waypoint in
between the other ones. In most cases you need to connect the waypoints
manually by using pathwaypoint (see below). If there is no connection
between the waypoints the Bots won't climb the ladder ! Color is purple.

"Rescue Waypoint"
This is only needed on Hostage Maps. It's the location where you want
the CT Bots to rescue the hostages. Usually only 1 is needed. Color is white.

"Goal Waypoint"
Place this at a position where Goals of the Map need to be achieved. In DE
maps this is a bomb plant spot and on cs maps Counter look here to rescue
some hostages. In AS maps these are the Escape points for the VIP. Color is
purple.

"Campstart Waypoint"
This is a camping (or sniper if you prefer) waypoint. To place it, look into
the direction you want the Bot to start looking at when camping. To let him
crouch at that position just press the duck button while adding it. You also
need to specify the:
"Campend Waypoint"
Selecting this will set the end direction for the Bot to look at when camping.
Look straight into the direction where you want the Bot to look and select it.
Note: you can't set a campend waypoint before doing a campstart waypoint.
Normal Color is cyan, if you made it team specific it will have a touch of red
if Terrorist WPT or blue if CT.

*NOTE*
To set a crouch waypoint, just keep holding your duck key. You certainly
noticed, I don't have different paths for different teams. I removed team
specific paths, since the Bots should be free (IMHO) to walk everywhere and
I secretly hated to to do waypoints for every team.
Also note that placing the "Important" waypoints differs from maptype to
maptype. On defusion maps, Terrorist will be able to choose a Terrorist
Waypoint OR a Counter Waypoint. Counter stay most of the time at Counter
Waypoints. On cs maps, Terrorists choose Terrorists waypoints most of the
time and Counters can walk to any Counter waypoint OR Terrorist waypoint.
All other waypoints will be chosen team independent (even camp spots).   


Using "waypoint delete" will remove the waypoint closest to the player.  The
waypoint MUST be within 40 units from the player (about 1/2 the player height)
in order to be removed.  You will need to stand fairly close to the waypoint
to be able to remove it.  This prevents you from accidentally removing a
waypoint on the other side of the room.  When removing a waypoint you will
hear a sound indicating that the waypoint was removed (the same sound the
tripmine makes when placed on a wall).

Waypoint addflag/deleteflag gives you some additional options for waypoints.
The first, "blockwithhostage" is rarely used. If you set this flag on a
waypoints Bots won't take this waypoint if a hostage is following them.
With the other two, you can make a campwaypoint team-specific.

Using "waypoint save" will save the waypoint data to the waypoint file.  The
waypoint file will have the same name as the current map with an extension
of ".pwf".  The file will be saved into the "cstrike/PODBot" Folder. Your
current player name will be saved as the waypoint file creator.

Using "waypoint load" will clear out all waypoints in the current map and
load them from the waypoint file in the maps folder.  This is a good way
to "undo" a bunch of waypoints that you have created but do not wish to
save.  There is no way to "undo" a single waypoint.  You will have to use
the "waypoint delete" command to remove waypoints one-by-one.


The "autowaypoint" command allows you to automatically drop waypoints as
you run around in a map.  To turn autowaypointing on use "autowaypoint on".
As you run around the level waypoints will be dropped every 200 units
automatically.  No waypoint will be dropped if another waypoint is already
within 200 units of your current position.  So if you want to place lots
of waypoints fairly close together you may have to manually place some of
the waypoints using the "waypoint add" command.  Autowaypointing keeps
track of where the last waypoint was dropped (either manually or from
autowaypointing) and will place another waypoint when you are 200 units
from the last waypoint.  If you don't like where autowaypointing placed
a waypoint and want to move it a little bit, you can delete the waypoint
using "waypoint delete" (but turn off autowaypointing before, since it
will place a new waypoint otherwise). 

When using autowaypointing, try to stay in the center of narrow hallways
and always place a waypoint on BOTH sides of a door.  You may have to place
some of these waypoints manually using "waypoint add" since places like
intersections of hallways and doorway entrances and exits don't usually
fall exactly at the location where autowaypoint would want to place a
waypoint.

The "pathwaypoint" command allows you to display what the bots would consider
to be a valid path from one waypoint to other waypoints.  Turn pathwaypoint
on using "pathwaypoint on" and whenever you get close to a waypoint
yellow or white lines will be drawn to all of the other waypoints that the bot
would consider to be "reachable". If the connection is a two-way connection the
line is yellow, one-way connections appear white. These "reachable" waypoints
would be waypoints that are clearly visible from the current location.  Certain
waypoints will be disallowed as reachable for one reason or another.  For
example, waypoints suspended in mid-air above the bot would not be considered
reachable since the bot couldn't jump high enough to get to them.  Also
waypoints that are too far away from the current location would not be
considered reachable.  You may have waypoints that are close enough to each
other, but across a wide gap that would be too wide to jump.  If the far
waypoint is close enough and clearly visible, it would still show as
"reachable" since I currently don't have a method to determine if the bot
can get to that waypoint or not.

The bots will ONLY go from one waypoint to another if there is a path between
them.  Get in the habit of turning on the pathwaypoint setting when creating
waypoint files so that you can see the waypoint paths and will know whether
or not a path exists between two waypoints.  Also get in the habit of checking
that paths exist BOTH WAYS between waypoints.  Just because a path is drawn
from point A to point B, doesn't mean that a path exists from point B to
point A.

The "pathwaypoint add <waypointnr>" command allows you to
manually assign a path between 2 waypoints.  This is needed in some cases
where the waypoints are blocked (by doorways or other objects) and you wish
to create a path between these waypoints.  Also ladder waypoints need to be
manually connected most of the time. Move close to the waypoint you
wish the path to start from and use the "pathwaypoint add x" command.
Of course the "x" must be replaced by a valid waypoint number. The actual
Waypoint Number you're standing on, will be shown in the upper corner of your
HUD (if you turned pathwaypoint on).
For example to manually assign a path between Waypoint Nr. 250 and 251,
you first should stand in the near of Waypoint Nr. 250. Then type in:
"pathwaypoint add 251" and it will get connected. 
You should now see a white waypoint path
line being draw from the start waypoint to the end waypoint.  Note that this
is a ONE-WAY connection.  If you wish to create a path back in the other
direction you will have to start with the second waypoint and end the path
back at the first waypoint.

The "pathwaypoint delete x" command is just like
the "add" command except that it removes a path (connection) from the
starting point to the ending point.  This is necessary in some cases where
you may have a door that opens from one side and allows you to go through
but once the door closes you can't go back through the other way.

When adding waypoints use the pathwaypoint feature to verify that waypoints
are actually reachable.  Sometimes you add a waypoint and it appears close
enough and it also appears to be in plain sight, but the Half-Life engine
doesn't indicate that the waypoint is "reachable". 
Be sure to check this in BOTH directions when defining a waypoint path.
Usually you don't have to be too careful about waypoint
placement, but in some situations, you may have to spend more time carefully
laying out waypoints to get them to be "reachable" (ladders are a good
example).

To set crouch waypoints, simply crouch when adding the waypoint.  You will
notice that the waypoint line is shorter than a normal waypoint.  Bot will
crouch automatically when approaching a crouch waypoint (if it's not a
camping waypoint).

Try placing waypoints at intersections in hallways (do use some 
"important" waypoints at crossings). Try not to place waypoints in
places where the bots would bump into corners of walls or other obstacles
when trying to get from one waypoint to the next.  Remember the bots won't
always take what you consider to be the "obvious" choice when choosing the
next waypoint.  Try to limit the choices that they have to keep them from
heading off in the wrong direction. Also remember that the Bots could go
backward in a fight and might not find a waypoint. In that special case
they wouldn't find a near enough waypoint (they only search in-between
200 Units) and get stuck forever. Since V1.4 it's important to have a lot
of waypoints together to allow the Bots a wider choice. Also put some
waypoints in corners or behind walls/doors so they can take good cover
positions. The Bots will try to take cover at waypoints
a) not seen by the enemy and
b) the one with the smallest wayzone radius in their range 

What are the Wayzones (displayed in blue lines starting from the origin
of the waypoint when pathwaypoint display is on) ?

Bots will pick a point inside this radius for their destination origin (based
on things like orientation etc.), this just makes movement not that "static".
Ladder waypoints, camp waypoints and goal waypoints will always have a radius
of 0. Don't try to change it ! After POD-Bot calculated all Zones you should
walk all over your waypoints to verify that they are reachable within their
radius. Try to be careful with the radius. If your path bends around corners
it's better to lower the radius. You should set the radius to 0 if the Path
goes through some narrow doorways or similar. You manually assign a new value
by standing near to the waypoint and typing "waypoint setradius x". Where x
is the value you want to assign. Valid ranges are 0-128. The bigger, the wider
it is. You'll also notice, if you turned on pathwaypointing some lines will
show you the radius of the actual waypoint (if it's not 0). 

Some further advices for making waypoints:
I start by typing "waypoint on". After that I type "autowaypoint on" and
"pathwaypoint on". Then I try to cover the map with waypoints everywhere
I want the Bots to roam. Then I try to think of the important points for
each team. I go to that position, delete the "normal" waypoint and instead
set a strategical waypoint at that position. Then I place the goal waypoints,
rescue waypoints and ladder waypoints. After that I calculate all wayzones
and try to detect waypoints with radius mistakes. Then I do a lot of test
playing until I'm finally satisfied with all the movement.
Don't do connections between waypoints on ladders
where Bots would have to shoot through vents (like in de_nuke).
They have some problems shooting their way out.
Don't do paths where Bots have to shoot breakable things under their feet
(like in cs_assault or as_tundra with the wood tunnel entrance). They
won't notice and will get stuck !
Don't use Paths through Doors which can only be opened through buttons.
They don't know how to activate them right now and will get stuck again... 

Phew ! I hope I didn't miss anything. Remember: the better the waypoint file,
the more fun it is to play with the Bots ! If they are stuck somewhere on
a map, it's usually the fault of the waypoint file creator...
