Challenge

Medium

Make the blue platform glide over the gap. Riding it comes next.

  1. In MovingPlatform, add [SerializeField] floats distance = 3f and speed = 1.5f, and public Vector3 delta;.
  2. In Update(), glide from the start to distance units along +x at speed, back again, and repeat.
  3. Set delta to the position after the move minus the position before.

Press Play: the platform glides out and back. Then Check.

Try it yourself

using UnityEngine;

public class MovingPlatform : MonoBehaviour
{
    // A later lesson fills this in: a platform that glides back and forth.
}
