Robocode 1.11.0

Version 1.11.0 (06-Jun-2026)

Changes

• Installer overhaul: Refactored the monolithic AutoExtract installer (844 lines) into 5 focused classes
  (Installer, InstallerDialog, Extractor, ShortcutManager, OsUtil).
• Reduced confirmation dialogs from 5 user prompts down to 1 — a single "Install to" dialog with Proceed/Cancel.
• Removed license agreement dialog, start-menu shortcut prompt, and Windows file associations prompt.
• Removed Windows .battle/.br file association registration (rarely used, required admin privileges).
• Removed legacy code: Win 9x/ME command.com path, obsolete .robotcache migration, fragile self-cleanup hacks.
• Windows shortcuts are now always created without prompting.
• Improved code quality: try-with-resources, StringBuilder, proper error handling, fixed spinner animation bug.

Bugfix

• #89: Prevent a single fire command from spawning duplicate bullets with the same ID
  • A single setFire() call could spawn multiple bullets sharing the same bullet ID, which could cause issues with
    bullet tracking and battle accuracy.
  • Thanks go to Pavel Savara for fixing this ❤️. Sharp-eyed fix!
