Enemy patrol (Walker)

This example shows a basic enemy patrol using Walker:

• move along waypoints
• optional obstacle avoidance
• optional debug rendering

Enemy with a walker

import { GameObject, SquareHitbox, Vector, Walker } from "sliver-engine";

class PatrollingEnemy extends GameObject {
  constructor(position: Vector) {
    super("enemy", position);
    this.addHitbox(new SquareHitbox(Vector.zero(), new Vector(16, 16), this));
    this.setPhisics({ immovable: false });

    const walker = new Walker(
      this,
      [new Vector(100, 100), new Vector(300, 100), new Vector(300, 220)],
      1.5,   // speed: px per tick
      true,  // debug
      true,  // cyclic
      {
        avoidObstacles: true,
        gridCellSize: 16,
        recalculateEveryTicks: 30,
      }
    );

    this.setWalker(walker);
    walker.start();
  }
}

Drop it into your scene:

mainScene.addGameObject(new PatrollingEnemy(new Vector(100, 100)));

If you don’t want pathfinding, remove the pathfindingOptions (or set avoidObstacles: false).
