Adding a Bot - 1

• The code found in the bot.cs script file was
  taken from a more complicated A.I. script called,
  aiPlayer.cs, which is part of the starter.fps
  example.
• Copy the bot.cs script to your tutorial.base/serve
  r directory.
• Open the game.cs script file located in the
  tutorial.base/server directory

4
Adding a Bot - 2

• Add the following line of script to the function
  onServerCreated( ) add it to the end of the list
  like usual
• exec("./bot.cs")
• Besides defining how our bot follows a given
  path, the bot.cs script also defines a special
  object called AIManager which is responsible for
  managing all bots in general
• For our AIManager to work, we'll need to add some
  code to start and stop it respectively.

5
Adding a Bot - 3

• Add the highlighted lines to the
  onMissionLoaded() function
• new ScriptObject(AIManager)
• MissionCleanup.add(AIManager)
• AIManager.think()
• Next, we need add a of line of code to the
  onMissionEnded() function to delete the manager
  object when our game is done.    
  AIManager.delete()

6
Adding a Bot - 4

• When done, close and save the "game.cs" script
  file.
• Note We haven't laid-out our path yet with the
  Mission Editor so the function AIManagerspawn(
  ), which actually spawns the bot, will simply
  spawn a regular bot without specifying a path to
  follow.

7
Path Definition - 1

• Run the test application by double-clicking
  torqueDemo.exe, which is located in the example
  directory.
• When the main menu comes up, click the "Load
  Mission!" button. A mission named, "F World",
  should load.
• After the mission starts, move forward a bit and
  turn around. You should see a motionless bot just
  standing there.

8
Path Definition - 2

• Find a relatively flat area where it will be
  easier to create a path and hit F11 to open the
  Mission Editor and switch to "World Editor
  Creator" mode.
• Expand the tree in the lower right half of the
  screen by clicking the "Mission Objects" entry.
  Expand it out like so
• "Mission Objects-gtMission"

9
Path Definition - 3

• In the Mission directory, you should see several
  entries to choose from.
• Click the entry labeled "Path" just once to
  create a new Path object. Name the Path object,
  "myPath".
• In the MissionGroup tree, which is in the upper
  right hand side of the editor, expand out the
  tree and find the node labeled "myPath".

10
Path Definition - 4

• Make this node the current selection by holding
  down the "Alt" key while clicking it with the
  mouse.
• If done correctly, the selection color of the
  "myPath" entry should change from white to gray.
• Make sure the path markers get grouped under our
  new Path object.

11
Path Definition - 5

• Return to the tree control in the lower right
  hand corner and click the PathMarker in the
  "Mission" directory.
• Name the new PathMarker, "myMarker0" and check to
  make sure it was correctly grouped under "myPath"
  in the "MissionGroup" tree control.
• Repeat the process to create two more PathMarkers
  called, "myMarker1, and "myMarker2".

12
Path Definition - 6

• Make sure to place the markers far enough apart
  so you can see your bot run around.
• Save the mission file by selecting and exit
  completely out of the game.
• return to the bot.cs script file located in the
  tutorial.base/server directory and edit the
  function AIManagerspawn()
• Comment out the line of code that creates "Bot_1"
  and uncomment the code below it that creates
  "Bot_2 and save bot.cs.

13
Test Bot

• Run the test application again by double-clicking
  torqueDemo.exe.
• If everything was done correctly, you should see
  a new bot called "Bot_2" running around your new
  Path object's PathMarkers.
• If not, make sure that your PathMarkers are not
  too low on the terrain and that they're correctly
  grouped under the "myPath" object.

14
Weapons Damage

• This tutorial demonstrates how to apply weapons
  damage to both players and bots when a weapon's
  projectile collides with them and how to
  calculate "radius damage", which allows an
  exploding projectile to damage a player without
  making direct contact.
• This tutorial not only requires the Tutorial Base
  application as its starting place, but also
  requires the addition of the Weapons and Bot
  Path-Finding tutorials.

15
Damage - 1

• Copy the scripts radiusDamage.cs and shapeBase.cs
  to your tutorial.base/server directory.
• Open the game.cs script file located in the
  tutorial.base/server directory and add the
  following script lines to the function
  onServerCreated()
• exec("./radiusDamage.cs")
• exec("./shapeBase.cs")

16
Damage - 2

• Copy the player_dieknees.dsq animation file to
  the /tutorial.base\data\shapes\player directory.
• Open the player.cs script file located in the
  \tutorial.base\data\shapes\player directory and
  following highlighted line of script to the
  datablock TSShapeConstructor
• sequence12 "./player_dieknees.dsq die"

17
Damage - 3

• This is the last change to this player.cs save
  the file and close it.
• Open the player.cs script file located in the
  tutorial.base/server directory and add the
  following line of script to the datablock
  PlayerShape
•     className Armor

18
Damage - 4

• Add this function to the bottom of the player.cs
  script.
• function PlayerplayDeathAnimation( this )
•   this.setActionThread( "die" )
• Add this function next.
• function Armordamage
• (this, obj, sourceObject, position,
        damage, damageType )   

19
Damage - 5

• Add this function next.
• function ArmoronDisabled( this, obj, state
  )    
• This is the last change to this player.cs save
  the file and close it.
• Open the rocket_launcher.cs script file located
  in the tutorial.base/server directory

20
Damage - 6

• Modify the datablock RocketProjectile datablock
  like so
• directDamage 50
• radiusDamage 25
• damageRadius 1.5
• Then modify the function RocketProjectileonColli
  sion
• function RocketProjectileonCollision
• ( this, obj, col, fade, pos, normal
  )    

21
Damage - 7

• That's it for rocket_launcher.cs save the file
  and close it.
• Run the test application by double-clicking
  torqueDemo.exe
• You should now be able to shoot and kill the
  path-finding bot as well as blow your self up by
  shooting at your player's feet.
