Bug fixes

Robocode 1.9.1.0

This is a maintenance release of Robocode, which primarily contains bug fixes, but also contains an updated version of the Eclipse Compiler for Java (ECJ) version 4.3.1.

Version 1.9.1.0 (22-Mar-2014)

Bug fix

• Bug-366: Receiving enemy's real name on HitByBulletEvent.
  • The previous fix was not correct for the owner and victim for the HitByBulletEvent and HitBulletEvent.
• Bug-368: Issues with sentries
  • All listed issues have been fixed.
  • A bullet from a sentry robot will not be able to hit another bullet within the "safe zone" any more, but will still be able to hit another bullet within the sentry border area.
  • When sentry robots are present on the battle field, the initial random positions will be located within the safe zone. This avoids robots from being punished by sentry robots from the start of the battle, as the robot did not enter the sentry border by itself.
• Bug-369: RoboRumble: NoClassDefFoundError for CodeSizeCalculator.
• The missing property robocode.battle.sentryBorderSize has now been added to the .battle file format.
• Fixed the twinduel.sh file which was using a invalid file name for the configuration file.
• Added desktop files for FreeBSD.

New features

• Due to one of the ideas in Bug-368, a new method getNumSentries() for Java and a NumSentries read-only property for .NET was added to the Robot and RobotStatus classes, and to the IBasicRobotPeer interface as well.

Changes

• Upgraded Eclipse Compiler for Java (ECJ) to version 4.3.1.

Robocode 1.9.0.0

The Robocode version 1.9.0.0 introduces a new robot type - the Border Sentry robot.
This is the final release before the final version of 1.9.0.0.

Version 1.9.0.0 (16-Feb-2014) The Border Sentry Robot Release

Bug fixes

• Bug-364: Robot Packager does not include the robot data dir in the .jar file.
  • The Robot packager has now been extended with an option to include data files too when packaging a robot.
• Bug-366: Receiving enemy's real name on HitByBulletEvent.
• Fixed various issues with the Robot Editor, e.g. letters written in the wrong error when typing text fast.
• Fixed issue when loading a robot jar file with no package (default package), which was found by Daniel Yeung, who also had a fix for it. :-)

New features

• BorderSentry interface: Added a new robot type (the BorderSentry) that allows you to implement border sentry robots, which are robots that guards the walls of the battlefield against "wall-crawlers" and "corner" robots.
  • The Border Sentry robot is dedicated to Liam Noonan from Limerick Institute of Technology and the Robocode Ireland event in general. :-)
  • The inspiration for this type of robot comes from the TV series named Robot Wars.
  • Note that border sentry robots...
    • have 400 additional energy points meaning that a border sentry robot starts with 500 energy points!
    • only appear at the borders of the battlefield, when a new round is started defined by the "border sentry size", which is a game rules that can be adjusted similar to other game rules. The default border sentry size is 100 units.
    • can only make damage to other robot types within the sentry border, but not to robots in the "safe zone", which is the area inside the sentry border.
    • can receive damage from other robots. But robots will not gain energy points from the border sentry robots (due to Mathew Nelson's excellent point regarding using sentry robots as "Energy Batteries" ;-) ).
    • does not receive scores in the Ranking Panel nor Battle Results, even though you can see its score, like ramming damage, bullet damage etc. The goal for the border sentry robot is to be a referee, but not a player that can win or loose the battle.
  • A new method names getSentryBorderSize() has been added to the Robot classes that returns the size / attack range from the edge of the borders, where BorderSentry robots are able to hit other robot types.
  • A new method named isSentryRobot() has been added to the ScannedRobotEvent event class.
  • When there is only one regular robot left on the battle field with one or more border sentry robots, the round is automatically ended.
  • A new sample robot has been added named samplesentry.BorderGuard. Try it out against your robot(s) or e.g. sample.Corners and sample.Walls.
  • An additional option has been added to the View Options in the Preferences to enable and disable the visual appearance of the sentry border, which is painted in transparent red (danger zone).
• Req-156: Codesize added to properties file.
  • The Robot Packager now adds a new property named robot.codesize which will be set to the value calculated by the built-in Codesize tool when compiling the robot and/or team. The Codesize value is the effective code size measured in bytes which is used by e.g. the RoboRumble to categorize robots into MicroBot, MiniBot and MegaBot etc.
• Improved the names of the menu items on the Robot menu.

Robocode 1.8.3.0

Robocode version 1.8.3.0 - The Editor Theme Release
(Changes since last version 1.8.2.0)

Bugfixes

• Bug-363: No Last Survivor Bonus being given.
• The getWidth() and getHeight() methods on the Robot class have always returned 40, even though a robot is 36x36 pixels in size.
• Hence, getWidth() and getHeight() have been changed to return the correct width and height, which is 36.
• Fixed Robot Editor issues:
• NullPointerException occurring with a new source file that was not saved before being compiled.
• Issue where the caret position was set to the end of a source file when reading it into the editor.

Changes

• Req-121: Change default battle settings like e.g. "Number of Rounds".
• A new Editor Theme Configurator has been added the allows changing the font, text colors and styles for the Robocode Editor.
• Two built-in themes have been provided for Robocode:
• Robocode White Theme
• Robocode BlackTheme
• When selecting a theme, Robocode will automatically use this theme the next time Robocode is started.
• When changing a theme, a new custom theme can be created and saved. Note that it is possible to overwrite existing themes.
• Editor themes are stored within the /theme/editor directory as theme property files, which makes it possible to modify these in a normal text editor, but also share the themes.
• The Editor Theme Configurator is available from the Robot Editor menu under View -> Change Editor Theme.
• The line numbers area in the Robocode Editor has been improved as well:
• The background and text colors for the line numbers can be changed.
• Line numbers are now right aligned + extra space has been added to the right.
• The Find & Replace dialog has got a better layout.
