📦 0.18.0 - Improvements to the Bot APIs - 18-Dec-2022

🪲 Bug Fixes

• Bot API
  • [Where to start developing a bot library in a different language #52]: The Bot API used comma-separated strings for authors, countryCodes, and gameTypes when parsing
    the BotInfo schema even though the [BotInfo/BotHandshake] uses string arrays. This was fixed to keep Bot APIs
    consistent with the schemas.
  • [at each tick the bots receives the full list of bullets #53]: Major bug where each bot received the bullet states of all bullets on the battle arena, including bullets
    fired by other bots, and not just the bullets fired by the
    bot itself.
  • Fixed issues with moving and turning, which could override the set target speed and turn rates, when these had
    been set explicitly on the API.
  • Reading the turn rates and target speed for the current turn did not reflect if the turn rate and/or target speed
    had been set for the current turn.
• Bot API for .Net:
  • Setting the max speed and max turn rates for the body, gun, and radar did not work.
• GUI app:
  • Fixed rendering issues on Windows (and Linux?) when using accelerated hardware, by setting these Java properties
  • as defaults:
    • sun.java2d.d3d=false (turn off use of Direct3D)
    • sun.java2d.noddraw=true (no use of Direct Draw)
    • sun.java2d.opengl=true (turn on OpenGL)

🚀 Improvements

• Bot API:
  • addCondition() and removeCondition() now returns a boolean value instead of void.
  • Condition can take an optional lambda expression as an input parameter as an alternative to overriding the test()
    method.
  • Added more test units, which did show bugs within the Bot API for both Java and .Net.
  • The event priority order was reversed to match the order used with the original Robocode.

📄 Documentation

You can read the Robocode Tank Royale documentation here.

🔨 Try it out

Please head over to My First Bot tutorial to learn how to set up your first bot for Robocode Tank Royale.

▶ 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-0.18.0.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

These sample bots are currently available:

Platform	Archive	Requirements
C#	sample-bots-csharp-0.18.0.zip	Microsoft .Net SDK 5.0 or newer
Java	sample-bots-java-0.18.0.zip	Any Java SDK 11 or newer

All bots are put in zip archives, which should be installed to independent directories.
Each zip archive contains a ReadMe.md file with more information for the specific platform.
