How can I make a procedural jump in Unity C#?

Question

I need to make a procedural jump in a board game in Unity C# (I conditionally have many points where the player has to jump from one to the other with different distances) which is called by the script. I cannot do animation because I need to calculate distance.

I've tried to use Vector3.Slerp which is much modified but it does not work like I imagined at all.

(There I've made another Vector3 because I need another axis in the jump)

Ideas ran out.

Please tell me how can I fix a problem in the script above or how I can do procedural jump else. Thank you so much.

Answer 1

Your index is always ever only to be 0. And the code you do in LateUpdate is fully redundant - simply assign the new position directly to transform.position.

I think what you are trying to achieve is to move your object smooth through the various positions provided by stand one by one.

So what you need is

• store the current target point
• move smooth towards it
• when reaching the target point
  • previous target point becomes new start point
  • get next target point

and do this until you reach the very last one.

You could e.g. do this in a Coroutine like

public float moveSpeed;

public void StartMoveThroughWaypoints(IEnumerable<Vector3> waypoints)
{
    StartCoroutine(MoveThroughWaypoints(waypoints));
}

private IEnumerator MoveThroughWaypoints(IEnumerable<Vector3> waypoints)
{
    foreach(var waypoint in waypoints)
    {
        while(transform.position != waypoint)
        {
            transform.position = Vector3.MoveTowards(transform.position, waypoint, moveSpeed * Time.deltaTime);

            yield return null;
        }

        // as the "==" above has only a precision of 1e-5
        // ensure to end with a clean position
        transform.position = waypoint;

        // optional add delay to shortly hold on each waypoint
        //yield return new WaitForSeconds(1f);
        // or at least for one frame
        yield return null;
    }
}
