Practice Final test

How to pass the practice

First, you should see hours-dotation (XLSX) for the whole course.

Then you should study scoring-system (XLSX) for the practice that gives you hints how you can obtain points and how many you need them to pass the practice (+strategy guidelines). You know, life is a game :-)

Long story short, you have to get at least 140 points to be admitted to Practice Final Test. If you obtain 170 points or more you automatically pass the practice (you don't have to go to Practice Final Test). You can get points for the attendance (2 for lesson), short tests (done ONLY during the lesson, 8 max), doing your homework assignments (typically 10 points) or by having high-quality tournament bots (up to 24 points per tournament).
If you obtain at least 110 points and want to pass, we will give you an extra assigment - based on your performance we will then admit you to Practice Final Test.

Test scoring details: you get 3 points if you will fill the test at the beginning of the lesson (in class ~ just by attending the lesson, you get 5 points for free!), you can get extra 5 points by answering questions correctly.

In order to get to the Final Exam of the Course you have to:

  • pass the Practice (by getting enough points and/or passing Practice Final Test)
  • do whatever Cyril says you have to do (participating in experiments, etc.)

Lectures History

Lecture 11 - (PPTX), (PDF)

  • Today's lesson concludes our lectures
    • We will go through last tournaments - Hide & Seek and DeathMatch
    • We will go through everything we have done
    • We present a checklist of things you should know before practice final test and exam
  • Bonus Assigment for those with less than 140 points - Create CTF Bot team in yaPOSH!
    • The do everything single CTF bot from previous assigment does
    • They cooperate with each other, details on slides

Lecture 10 - (PPTX), (PDF)

  • Today's topic is Capture the Flag (CTF) UT2004 game mode and CTF Bot in yaPOSH
    • Few navigation tips
    • Learn about CTF game rules
    • Try to combine CTF Bot actions and senses to create meaningfull CTF behavior
  • We will start from: yaPOSH CTF Bot Stub 3.5.2-SNAPSHOT
  • Create CTF Bot in yaPOSH!
    • Bot arms himself before going into the action
    • Bot tries to get enemy flag
      • Checks whether he can score
    • Bot fights enemy flag carriers and pick up own flag when he sees it on ground

Lecture 9 - Updated slides from lecture 8: (PPTX), (PDF)

  • Today's topic is advanced POSH and DeathMatch Bot
    • We have shown how to make parallel actions in POSH (using action pattern and ActionResult.FINISHED)
    • We have shown how to parameterize actions and senses (see slides for examples)
    • We have shown that ActionResult.FINISHED triggers immediate POSH plan re-evaluation and can lead to infinite loop if not used correctly (preventing new updates from UT2004 to come and reach your plan)
    • We have shown that POSH plan re-evaluates until it finds new action to execute - if it doesn't find and action to execute it will be stuck in infinite loop again!
      • Always have last default rule in the POSH plan with action doNothing - this will prevent this kind of problem
    • Short duration action (or immediate actions) should return ActionResult.RUNNING_ONCE, only reason to return ActionResult.FINISHED is in actions in action pattern when you want to have them parallelized (see slides for correct usage)
  • We will start from: SPOSH Attack bot 3.5.1
  • No new Assigment for lecture 9
    • We were coding Assigment 8 from last lecture. Send us DeathMatchBot in POSH!

        • Try to be really clever about this, prioritize items in best-you-can do order
          • I.e., don't make obvious mistakes like “rocket ammo better than 50 armor”
      • Does not stuck (its ok, if he occasionally freezes somewhere for a few seconds, but not forever!)
      • If he sees the item he wants is not there (e.g. you run three collector bots and the other one got it first), he re-plans and goes for a different item
      • Use DM-1on1-Albatross map

Pogamut 3 platform

Installers:

  • Pogamut UT2004 3.5.0 and Pogamut Emohawk Installer 3.5.0. Get them at Pogamut download page
  • Date: 25.2.2013
  • For Pogamut UT2004 Installer you have to have UT2004 installed somewhere.
  • Both installers will install: Maven 3.0.4, NetBeans plugins, Pogamut Example archetypes. Note that you need NetBeans 7.1.2, otherwise Pogamut archetypes won't be accessible from NetBeans context menu (New Project → Maven → Project From Archetype → Local Archetypes Catalog).
  • Before you launch the bot, you need to start Unreal server:
    • For UT2004, go to directory Unreal Anthology/UT2004/System and there launch startGamebotsDMServer.bat. To observe the bot in the environment launch startUT2004low.bat from the same directory.
    • For UnrealEngine2Runtime, go to directory UnrealEngine2RuntimeDemo/System/ and there launch startEmohawkServer.bat. To observe the bot in the environment launch startUE2Runtime.bat (after the server is launched).

Alternatively

  • If you have UT2004 installed, you can follow guidelines of tutorial Pogamut 3 quickstart tutorial found at Pogamut Documentation page. However, we recommend to use installers above.

FAQ

Q: I am missing help on all methods, attributes and classes (Javadoc is not working). :-/
A: In NetBeans open your project and right click the Dependencies folder, click Download Javadoc, NetBeans should now download Javadoc and the help should be working. If it is not, click also Download Sources and after it is done (watch lower right progress bar) restart NetBeans. Sometimes NetBeans refuse to show help - it can be usually resolved by trying to Download Javadoc several times.

Q: How to get account in our computer laboratory for non-MFF students?
A:

  • a) Print and fill up this form: http://www.ms.mff.cuni.cz/students/externisti.html.cs
  • b) Get the network administrator of students school to sign the form above (if you are unable to get the signature, then ask Cyril Brom)
  • c) Go to the SISAL, Mala Strana, fourth floor - in the corridor in the back and there they will create an account for you

Q: How do I create PogamutUT2004 Bot project in NetNeans from archetype?
A: Its easy. Simply click New Project, from categories choose Maven. From projects choose Maven project. Click on Next. Click on Add… button and the NetBeans will ask you about archetype details. That is :

Full list of available archetypes can be found here. (always use repository above)

Also be sure that NetBeans is using Maven 3.0.4! Obtain Maven from here: Maven 3.0.4. After unpacking, go to NetBeans→Tools→Options→Miscellaneous→sheet Maven→set Maven home directory.

Q: I have a problem with imports - the NetBeans help doesn't work. :-/
A: Two solutions, either add PogamutUT2004.jar and PogamutCore.jar to libraries to your project (the help should be working), or add imports to your class manually. Some useful imports: 

import cz.cuni.amis.pogamut.base3d.worldview.object.*; //for Location, Velocity..
import cz.cuni.amis.pogamut.ut2004.communication.messages.gbcommands.*; //GB commands
import cz.cuni.amis.pogamut.ut2004.communication.messages.gbinfomessages.*; //GB messages

Q: I am a student and want to use Pogamut, but I don't have UT2004.
A: Unfortunately school cannot provide you with UT2004 - however you are free to use Pogamut in SW1 laboratory (when it is free) and there is one Pogamut computer in MS lab (far end against the entrance) where we can create an account for you. Second solution is to use UnrealEngine2RuntimeDemo exclusively, which is free for educational purposes and which is installed with Pogamut Emohawk installer.

Q: How to disable master server authentication in UT2004?
A: In UT2004/System/UT2004.ini find [IpDrv.MasterServerUplink] and set the following: 

[IpDrv.MasterServerUplink]
DoUplink=False
UplinkToGamespy=False
SendStats=False

Q: I'm trying to setup @EventListener or @ObjectClassEventListener in POSH actions (or senses) and they are not working, why?
A: These listeners works only in XxxContext classes. You have to declare them there and then access them from actions or senses.

Q: How can I tell what version of Unreal Tournament 2004 I am running (v. 3369 required)?
A: Just start Unreal Tournament 2004 GUI, open the Join Game tab and the news page will have the number in the upper right corner.
