0.13.1

0.13.1 - Fixing event queue + country codes

Bugfixes

• Bot APIs:
  • Fixed issue with turning the body, gun, and radar as first and only
    thing (#23).
  • Fixed issue with rescanning and interrupting current event handler. Redesigned the event queue.
  • Fixed issue with dangling threads not been stopped (interrupted) correctly.
• Bot API for .Net:
  • Fixed issue with country codes (on macOS) which also caused boot up problems for .Net based bots running under
    macOS (#20).
  • Fixed issue with bots stopping doing actions when battle is restarted. E.g. the Corners sample bot was affected by
    this issue.

Running Robocode

You need Java 11 as a minimum or newer to be preinstalled on your system. I recommend newer versions of Java, e.g. version 18.
You can read the installation guide to get more details about installing Java and Robocode.

The Robocode GUI application must be run from the command line in order to start and view battles:

java -jar robocode-tankroyale-gui-0.13.1.jar

robocode-tankroyale-gui-0.13.1.jar

Note that you need to download sample bots and install those into directories on your system, and add these directories from the menu:

Config → Bot Root Directories

Sample bots

These sample bots are currently available:

C#: sample-bots-csharp-0.13.1.zip
Java: sample-bots-java-0.13.1.zip

Note that the C# bots need Microsoft .Net SDK 5.0 or newer and must be preinstalled.

Bot API

In order to develop bots for Robocode, you'll need one of the provided APIs for the Java/JVM or .Net platform.

Java:

Available as a jar file: robocode-tankroyale-bot-api-0.13.1.jar

Available as an artifact on the Sonatype Nexus Repository here. At some point after this release the artifact will also become available from the Maven Central Repository.

.Net:

Available as artifact on the Nuget repository:
https://www.nuget.org/packages/Robocode.TankRoyale.BotApi/0.13.1

dotnet add package Robocode.TankRoyale.BotApi --version 0.13.1

0.13.0

0.13.0 - Bot API for .Net 6

Changes

• Bot API:
  • Upgraded the .Net version of the bot API for .Net 6.0 as .Net 5.0 is soon EOL.
  • The id was removed from BotResults, and GameEndedEvent will only return a single BotResult containing
    the battle results for the bot (instead of a list containing results from all bots).
  • Added setting and getting 'adjusting radar for body turn'.
  • The scan() and setScan() methods were renamed to rescan() and setRescan().
  • Added setInterruptible(boolean interruptible) / Interruptable = [bool] to allow restarting an event handler
    while it is processing an earlier event.
• GUI:
  • A tooltip text has been added to the 'Start button' that shows the minimum or maximum number of participants
    required for starting the battle.
• Protocol:
  • Removal of the speed field of the bullet-state as the speed can be calculated as: 20 - 3 x power.
    Hence, there is no need to transfer this information over the network.
  • Moved id from bot-results-for-bot to bot-results-for-observer.
  • The scan field on bot-intent was renamed to rescan.

Bugfixes

• Bot API:
  • Blocking bot functions do not stop bot after
    finishing (#17).
  • Fixed issue where event queue would overflow with unhandled events when a Bot´s run() method has ended.
• GUI:
  • The 'Start game' button is now disabled when the minimum or maximum number of participants is not met.

0.12.0

0.12.0 - Single stepping battle

Changes

• GUI:
  • Added 'Next turn' button beside the pause button in with the control panel to useful for single-stepping a
    battle, e.g. when debugging your bot.
  • Improvements to the battle dialog for selecting game type and bots for a new battle.
    • Added button for setting up rules.
    • Added tooltip texts.
• Protocol: Removal of rgb-value type from the protocol of Bot APIs.
• Bot API: The Color.fromRgb() has been replaced by Color.fromString().

Bugfixes

• Bot API: Make sure the bot terminates (system exit) upon a connection error to prevent dangling bot processes, which is
  usually occurring when terminating the UI, which closes the bot connections.
• GUI: When dragging the battle arena, the graphics were not updated while dragging.

0.11.0 - Initial position feature

Bugfixes

• Fixes for building Java artifacts to deploy to Maven artifactory.
• Bot API: Replaced the environment variable BOT_URL (deprecated) with BOT_HOMEPAGE.
• Bot API for .Net: Added missing public Bot(BotInfo, Uri, string serverSecret) constructor.

Changes

• Implemented initial position feature:
  • Add an initialPosition field in the JSON file for your bot with a value like 50,50,90 to request a starting
    coordinate at (50,50) with the bot heading toward 90°.
  • A --enable-initial-position (or the short version -I) must be set to enable the initial positions feature on
    the server. If initial position is not enabled, the bot will start at a random position.
  • Initial positions can be set from the menu with Config → Debug Options → Enable initial start position.
  • The Target.json file of the Target sample has been updated with an initialPosition to demonstrate this feature.
• Updated the SpinBot sample bot for C# to demonstrate the use of BotInfo.FromConfiguration(IConfiguration).
• The config file named misc.properties has been renamed into config.properties and the server-url setting was
  moved to the server.properties file.
• When the server settings are changed on the GUI, the user will be asked if the server should be rebooted to let the
  changes take effect.

  extended for setting this as input parameter in the constructor.

• Client is disconnected when sending a wrong secret to the server.
