Are you tired of seeing bots getting stuck in corners or staying
in the same area , then you need waypoints !!!

because the Esf-bot is based on botman's bot I thought well
it must have the same commands , and it did !

If you don't know what waypoints are or don't know how to
add/delete them then read this Tutorial .
(there's some TFC stuff in there but don't pay attention to that)



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 HPB 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.

Waypoints are stored in a file with the same name as the map file name but
using the extension ".wpt" instead of the map file extension of ".bsp". For
example, the waypoint file for the map 2fort would be 2fort.wpt (it will be
stored in the Half-Life\tfc\maps folder where the 2fort.bsp file would be).
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

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

"waypoint on" - Turns on displaying of waypoints.
"waypoint off" - Turns off displaying of all waypoints.

"waypoint add" - Adds a waypoint at the current player location.
"waypoint delete" - Deletes the waypoint nearest to the player (see below).

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

"waypoint menu" - Displays a menu for setting tags on a waypoint (see below).

"waypoint info" - Shows information about the current waypoint (see below).

"waypoint update" - Automatically adds waypoint tags for health, armor, ammo
and weapon to existing waypoints in a map (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 enable" - Enables creation of paths between waypoints
"pathwaypoint disable" - Disables creation of paths between waypoints.

"pathwaypoint create1" - Sets the first waypoint in a manual path (see below).
"pathwaypoint create2" - Sets the second waypoint in a manual path
"pathwaypoint remove1" - Sets the first waypoint in removing a path.
"pathwaypoint remove2" - Sets the second waypoint in removing a path.


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. If you want bots to jump off of ledges or buildings, you will need
to place a waypoint in mid-air to get the bots to run towards it. 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).

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).

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 ".wpt". The file will be in the same directory as the map file (in the
maps folder).

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.

Using "waypoint menu" allows you to set special tags on each waypoint.
When you are close to a waypoint and use the "waypoint menu" command, you
will be presented with a menu of options that will set or clear tags on the
waypoint. These tags include things like: waypoint specific for one team,
flag is located at this waypoint, flag capture point is located at this
waypoint, this waypoint is a sniper spot, etc. The menus appear as follows...

1. Team Specific
2. Wait for Lift (elevator). (NOT IMPLEMENTED AT THIS TIME!!!)
3. Door
4. Sniper Spot
5. MORE...

You select these using the keys bound to "menuselect 1", "menuselect 2", etc.
Which are typically the number keys 1 to 5. When you select "Team Specific"
you are presented with the following menu...

1. Team 1
2. Team 2
3. Team 3
4. Team 4
5. CANCEL

Selecting one of these will cause the waypoint to ONLY be reachable by that
specific team. If you select the "MORE" item from the first menu you are
presented with the following menu...

1. Flag Location (where the flag is located in the enemy base)
2. Flag Goal Location (where you need to return the flag to)
3. Sentry gun (engineers will build a sentry gun here)
4. Dispenser (engineers will build a dispenser here)
5. MORE

Selecting item 1 (flag location) will mark this waypoint as the location
where the enemies flag resides. Note that you MUST ALSO mark this location
as team specific for one of the teams in order for the bots to know WHICH
flag location is the one they want to head towards. For example, in 2fort
you would mark the RED teams' flag location as a BLUE team only (team 1)
waypoint and mark that same location as a "Flag Location". You would also
need to mark the BLUE team capture point as team specific (team 1) and mark
it as a "Flag Goal Location". You would need to do the reverse for the RED
team (i.e. BLUE teams' flag location is RED team only (team 2) and is a "Flag
Location" and RED teams capture point is RED team only (team 2) and is a "Flag
Goal Location".

If you select "MORE" you will be presented with the following menu...

1. Health
2. Armor
3. Ammo
4. Jump
5. CANCEL

Selecting "Health", "Armor" or "Ammo" will mark the current waypoint with
the HEALTH, ARMOR, or AMMO tag (respectively). This allows you to manually
tag waypoints with these flags when the waypoint code does not automatically
do so for you.

The "Jump" waypoint is used to tag a waypoint where you want the bot to jump
over something in order to reach some item in a map. There will be an aiming
waypoint (similar to the sniper and sentry gun aiming waypoint, see below)
when you add the Jump tag. This aiming waypoint is used to indicate which
direction the bot should be heading in order to jump. To insure that the bot
is approaching from the proper angle to jump over something in a map (like
a gap), you should place another waypoint a little bit away from the "Jump"
waypoint in the opposite direction of the area you want to jump. Make sure
that the only waypoint paths to the "Jump" waypoint are from this other
waypoint. That way you know the bot will approach the second waypoint,
turn to face the jump waypoint, and the jump across a gap.

When creating a sniper waypoint, make sure you are facing in the direction
you want the sniper to aim before selecting the sniper waypoint option from
the menu. When setting a sniper waypoint you will see a little blue waypoint
line in mid-air near the sniper waypoint. This little blue line indicates
which direction the snipers will face when they reach the sniper waypoint.

When creating a sentry gun or dispenser waypoint, make SURE that you aren't
too close to a wall or other object that will prevent the sentry gun or
dispenser from being built. There is an aiming waypoint for sentry guns
and dispensers just like there is for snipers. Make sure you are facing
in the direction you want the bot to face before marking the waypoint as
a sentry gun or dispenser waypoint. REMEMBER! Sentry guns will wind up
facing in the OPPOSITE direction of the direction the player is facing
after they are built. Make SURE you face AWAY from the direction you want
the sentry gun to face before creating a sentry gun waypoint.

Sentry guns and dispensers require metal (armor) to be built. In order for
the bots to know where armor is located, I am using the ARMOR waypoints
(the ones located near the little red vests). Although there are other
backpacks that contain armor, I don't know how to determine which backpacks
contain armor and which do not (the little red vests are ALWAYS armor).
Bots will not be able to build sentry guns or dispensers very well in maps
that don't contain armor vests. If you place sentry gun or dispenser
waypoints and bots don't appear to be building things then they probably
don't know where to collect armor from. You may need to manually add an
ARMOR tag to waypoints that are located next to backpacks that contain
armor.

If you select a tag on a waypoint that you don't want, you can select the same
tag again to TOGGLE it back off. Select it once, it's on, select it again,
it's off. Use the "waypoint info" command described below to determine which
tags are set on specific waypoints.

Using "waypoint info" will tell you information about the current waypoint.
You must be near the waypoint in order to get information about that waypoint.
The "waypoint info" command will display the current waypoint number and any
special tags for that waypoint. There is currently a maximum of 1024 waypoints.

Using "waypoint update" will allow you to take an existing waypoint file
and automatically tag each waypoint with "Health", "Armor", "Ammo" or
"Weapon" tags. The versions of the HPB bot before release 1.4 didn't know
how to detect health, armor or ammo within TFC backpacks. The current
version of the HPB bot does know how to detect this. You can use the
"waypoint update" command to update these older TFC waypoint files to
indicate which backpacks contain health, armor or ammo. This is necessary
by engineer bots in order to find metal so that they can build sentry guns.

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", move to another location, then use "waypoint add"
to drop a waypoint where you want. Even after deleting the waypoint placed
by autowaypointing, the autowaypoint code will remember that location and
not try to place another waypoint (unless you go more than 200 units from
the location where you deleted the autowaypoint). Without this, you would
delete the waypoint, move a little bit, and autowaypointing would immediately
place another waypoint (probably where you didn't want it).

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 (on your
team), white lines will be drawn to all of the other waypoints that the bot
would consider to be "reachable". 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 enable" and "pathwaypoint disable" allows you to turn on
or off the automatic adding of paths between waypoints. The default setting
is enabled. If you want to add waypoints without getting a bunch of paths
automatically added, you can use "pathwaypoint disable" before adding a
waypoint and no paths will be added. You can then manually create a path
using the "pathwaypoint create1" and "pathwaypoint create2" commands which
are described below.

The "pathwaypoint create1" and "pathwaypoint create2" commands allow 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. Move close to the waypoint you
wish the path to start from and use the "pathwaypoint create1" command. You
will hear a sound indicating that waypoint is selected. Now move to the
second waypoint where you want the path to terminate. Use the "pathwaypoint
create2" command to end the path. 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 remove1" and "pathwaypoint remove2" commands are just like
the "create1" and "create2" commands except that they remove a path 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. An example
of this is the spawn rooms in 2fort.

Sometimes you have to be a little creative when using the "create1", "create2",
"remove1" and "remove2" commands. When editing the waypoint paths on 2fort
there were several times when I had to use the "remove1" command then use
"kill" to kill myself so that I could get back into the spawn room, before
using the "remove2" command to remove a path going back into the spawn room
through a door that I could not get through.

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". The spiral stairs in
2fort are one example where I had to continually add and delete waypoints
until I found the exact spot where the pathwaypoint showed waypoints were
actually 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".

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.

Try not to place too many waypoints too close together, this just slows the
game down and really doesn't serve any purpose. Try placing waypoints at
intersections in hallways and try to avoid placing waypoints too close to
walls or ledges (the bots have some slop in how close they have to get to
a waypoint to be considered "touching" it). 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.

THE END



So everyone just make waypoints so that the people with
bad connectoins can play all the maps with bots !

If you made any waypoints for an ESF map then please post
them here :)

ps: If you are a beginning waypointer then first try the easier
maps and then the harder ones !


TO THE MODERATORS : please make this a sticky, alot of people
will apreciate it .

You don't think the bot needs waypoints?
Have you ever played esf_city , after 2 minutes all the bots are behind the buildings on the edge of the map or they are stuck in a corner!
In esf_lavapit they all jump straight in the lava !
In esf_kami they all fall of kami's palace !
almost every level has some problems !

all of these problems can be solved by adding (good) waypoints!



The bots work without waypoints ,but if you make (decent) waypoints then the bots are waaay better !
and its alot more fun :p

If you make a bot with waypoints then the moves will be completely predictable after a couple games. In other words:

BOOOOOOOOOOOOOOOOORRRIIIIIIING! :D

I finished 2 waypoints
esf_namek (good not great )
esf_riverside (great bots take alot of different routes)

I'll email them to a person with a site and then you can all
download them , I just need someone who wants to host these
waypoints ! any volunteers .....


ps : TO THE MODERATORS : PLEASE MAKE THIS A STICKY

EDIT: Blade you say that bots who use waypoints are predictable
thats not true , if you suck at waypointing then the botswill always take the same routes , but if you are good then the bots will take alot of different routes !
It all depends on your waypointing skills ;)

couldnt you have linked to a text file, my pc nearly crashed from scrolling too fast! :cry: (lame P4s)

i think its great that someone is making waypoints, ill probably only use them on a couple of maps where bots are really bad tho cos they do make it too predictable

dont you have your own webspace where you can upload them too?
i really want the riverside waypoints, its a great map but the bots seem to preffer swiming in the river than fighting :S

I'd like to give you the waypoints but it seems that people
won't host these waypoints ! There just really small files !

At the moment i'm making waypoints for esf_mtside .


Has anyone else here started waypointing ?

And waypoints dont make the bots predictable , the bots
will follow the waypoints that you made , but if they see
an enemy they'll attack it and they don't care about
waypoints when they're engaging an enemy !

Look people ,do you want more waypoints or not ?
Because if nobody wants them then i'll keep them for
myself ;/

request : Could someone with good waypoint skillz waypoint esf_city please ? because that's a hard map to waypoint.
