0.23.0

📦 0.23.0 - Fixing movement bugs in bot APIs - 29-Apr-2024

🪲 Bug Fixes

• Bot API:
  • #80: Fixed a major bug causing the body, gun, and radar to move in a wrong angle, which could be seen with
    the Walls sample bot.
  • #85: Fixed a major bug in server.rules.math::calcNewBotSpeed. Thanks goes to Mark (mnbrandl) for fixing this! 😊
• Server:
  • #83: Bots receives skipped-turn-event events while dead.

🚀 Improvements

• Bot API:
  • Extended the GameStartedEvent with the InitialPosition property containing the starting position and shared
    direction of the body, gun, and radar. This helped on fixing #80
  • Renamed the "Angle" property of InitialPosition to "Direction".

▶ Running Robocode

You need Java 11 as a minimum or newer, e.g. the newest version of Java available.

You can read the installation guide to get more details about installing both Java and Robocode.

The main application is the GUI Application, which is a Java application.
You can read more about how to use the GUI Application here.

The Robocode GUI application is run from the command line (shell or command prompt) in order to start and view
battles:

java -jar robocode-tankroyale-gui-0.23.0.jar

If you are new to Robocode, you need to download some bots and extract those to directories on your system.
These bot directories can be added from the menu of the GUI: Config → Bot Root Directories

🤖 Sample bots

0.22.0

📦 0.22.0 - Improved ANSI support - 03-Dec-2023

🚀 Improvements

• Bot API:

  • When running a bot from the command line, stdout and stderr will also be printed out in the bot console.

• GUI:

  • The Bot Console and Server Log have been totally rewritten to improve performance (is not used HTML rendering
    anymore)
  • The logo in the server log in now shown with ANSI colors per default (might not work on all systems?)
  • The bot console now writes out the turn numbers from the previous turn, when output from the bot is written out.

🪲 Bug Fixes

• GUI:
  • #75: The GUI could get stuck and become unresponsive when displaying the busy pointer on Ubuntu.
  • #77: Unreadable Server Log on NixOS.
  • The scores presented after the battle has ended was not accumulated for all rounds, and hence incorrect.
  • The Properties tab of the Bot Console did not show any values when initialized, e.g. when game is paused.
  • Some stdout text from the bot were sometimes missing in the Bot Console. Solved by using the EDT.

0.21.0

📦 0.21.0 - Improved scoring - 02-Oct-2023

🚀 Improvements

• Bot API:
  • Added stop(boolean overwrite) and setStop(boolean overwrite) to overwrite the saved movement from a previous
    call to setStop() with current movement values. These methods provide backwards compatibility with the original
    Robocode with the [Robocode API Bridge] (in progress).
  • Due to the removal of Java's Thread.kill() and .Net's Thread.Abort(), the main thread of the bot is no longer
    being killed by those methods is those threads could not be interrupted. Instead, the bot process it shut down
    with an error message:
    The thread of the bot could not be interrupted causing the bot to hang. So the bot was stopped by force.

🪲 Bug Fixes

• Scoring:
  • Fixed various scoring issues when comparing to original Robocode.
• Bot API:
  • Fixed race condition when adding custom events.
• Bot Console:
  • Events are only printed out while the bot is alive or has just died.
  • The DeathEvent was missing.

0.20.0

📦 0.20.0 - Added support for teams and droids - 23-Aug-2023

🚀 Improvements

• Team support:
  • Added support for teams, where a team is a group of bots that work together to battle against other teams (or bots). Each team member can communicate with the other teammates, which is crucial to share information and coordinate movement and attacks.
• Droid interface:
  • A Droid interface was added that turns a bot into a droid bot, which has no radar but has 120 initial energy points instead of the normal 100 starting points. The droid is intended for team bots.
• Sample Bots:
  • MyFirstTeam has been added to demonstrate how to set up a team.
  • MyFirstLeader is a team bot that has been added to demonstrate a (leader) bot that is responsible for scanning enemy bots and sending the coordinates of the current target, to fire at, to the teammates.
  • MyFirstDroid is a team bot that is a droid, and hence comes with no radar, and relies entirely on the MyFirstLeader to send data about which target coordinate to fire at.
• Bot API:
  • Added the TeamMessageEvent which is received when another team member has sent a message.
  • Added these new methods to support teams:
    • getTeammateIds() to get the ids of all teammates in a team.
    • isTeammate(botId) to check if a bot with a specific id is a teammate or opponent.
    • broadcastTeamMessage(message) broadcasts a message to all team members.
    • sendMessage(botId, message) sends a message to a specific team member.
    • onMessageReceived(TeamMessageEvent) is an event handler to take action when a team message is received.
  • Added the Droid interface (no scanner, but 120 initial energy points).
• Booter:
  • Updated to support booting teams besides bots.
  • Changed the name of the run command into boot.
  • Changed command option -T into -g for filtering game rules (-t is now used for the team-only option).
  • Added --botsOnly and corresponding -b option flag for filtering on bots only (excluding teams).
  • Added --teamsOnly and corresponding -t option flag for filtering on teams only (excluding bots).
• GUI:
  • Added Directory Filter dropdown to filter on bots and teams.
  • The results window now aggregates scores for teams as well as bots and got a wider "Name" column. Some column names were changed, and tooltips were added to fields containing values/scores.
• Schema:
  • Renamed bot-results-for-bot and bot-results-for-observer into results-for-bot and results-for-observer as participants now include teams and not just bots.

🪲 Bug Fixes

• GUI:
  • The GUI could get stuck and become unresponsive when displaying the busy pointer.
