Overview

This page describes the API for the BZRobots Programmable Computer Player Client.


The BZRobots API is based heavily on the robocode project. It is class-based, meaning that a robot is built by extending from one of the following four classes:

  • BZRobot (An easy-to-use robot with a simplified API, e.g. degree units, etc.)
  • BZAdvancedRobot (A robot with more advanced features in the API, e.g. radian units, etc.)
  • Robot (Similar to BZRobot - for robocode compatibility)
  • AdvancedRobot (Similar to BZAdvancedRobot - for robocode compatibility)


The main control loop is created by overriding the class method run, and then using the methods shown below to control the robot. These control methods fit into two categories 'blocking', and 'non-blocking'. A blocking function, once called, will not return until either the requested action has completed, or the amount of time allotted for a "turn" or "tick" has passed - whichever comes later. Non-blocking functions will return immediately, allowing for additional processing, but their actions do not take effect immediately; rather, they will take place when the execute method is called. After a blocking function has been called, various "events" that have been generated during that turn may be processed by the various event methods, if they have been overridden.


Note: As BZRobots currently supports bot scripts written in three different languages, the following is a language independent description of the methods available for bot development.
