About Walls in Robocode

Robocode does not have "custom walls". It only has the standard walls on the sides of the battlefield.

Bullet Miss Events

When a bullet gets outside of the battlefield, this is considered a "bullet miss". You can capture this event using:

onBulletHitWall(BulletHitWallEvent event)

Custom Events

You can also create your own custom events using:

onCustomEvent(CustomEvent event)

How Custom Events Work

  1. You instantiate a CustomEvent that takes a Condition as input
  2. The Condition is your own (inherited) class
  3. You need to implement the test() method to define when the event is fired on your own terms

Example Structure

public class MyCustomCondition extends Condition {
    @Override
    public boolean test() {
        // Your custom logic here
        return true; // or false based on your conditions
    }
}

This allows you to create sophisticated event-driven behaviour in your robot based on any criteria you define.
