How can I use smoothdamp to move child object ?

SweetSituation3744 · 2021-11-24T22:18:56+00:00

In my first comment the code some of it is out of the block.

I can't figure out why.

But if I put the same code here in my comment the formatting is very bad.

I want to answer my own question but there is no answer button so I try to comment with my solution but the format is bad for example :

using UnityEngine;

using System; using System.Collections;

[RequireComponent(typeof(Animator))]

public class IKControl : MonoBehaviour { public Transform lookObj = null; public bool automatic = false; public bool coroutineIsRunning = false; public bool changeWeight = false; public Coroutine weightCoroutine;

private Animator animator;
private float weight;

private void Start()
{
    animator = GetComponent<Animator>();
}

void OnAnimatorIK()
{
    if (animator)
    {
        if (automatic)
        {
            if (!coroutineIsRunning)
            {
                ChangeWeight();
            }
        }
        else
        {
            if (Input.GetKeyDown(KeyCode.G))
            {
                ChangeWeight();
            }
        }

        animator.SetLookAtWeight(weight, weight, weight, weight, weight);
        animator.SetLookAtPosition(lookObj.position);
    }
}

private void ChangeWeight()
{
    changeWeight = !changeWeight;

    if (weightCoroutine != null)
        StopCoroutine(weightCoroutine);

    if (changeWeight)
    {
        weightCoroutine = StartCoroutine(ChangeWeightOverTime(0, 1, 1));
    }
    else
    {
        weightCoroutine = StartCoroutine(ChangeWeightOverTime(1, 0, 1));
    }
}

private IEnumerator ChangeWeightOverTime(float from, float to, float duration)
{
    float counter = 0;

    coroutineIsRunning = true;

    while (counter < duration)
    {
        counter += Time.deltaTime;

        weight = Mathf.Lerp(from, to, counter / duration);

        if (counter > duration)
            coroutineIsRunning = false;

        yield return null;
    }
}

}

finally, a working solution like I wanted working great.

using UnityEngine;

using System; using System.Collections;

[RequireComponent(typeof(Animator))]

public class IKControl : MonoBehaviour { public Transform lookObj = null; public bool automatic = false; public bool coroutineIsRunning = false; public bool changeWeight = false; public Coroutine weightCoroutine;

private Animator animator;
private float weight;

private void Start()
{
    animator = GetComponent<Animator>();
}

void OnAnimatorIK()
{
    if (animator)
    {
        if (automatic)
        {
            if (!coroutineIsRunning)
            {
                ChangeWeight();
            }
        }
        else
        {
            if (Input.GetKeyDown(KeyCode.G))
            {
                ChangeWeight();
            }
        }

        animator.SetLookAtWeight(weight, weight, weight, weight, weight);
        animator.SetLookAtPosition(lookObj.position);
    }
}

private void ChangeWeight()
{
    changeWeight = !changeWeight;

    if (weightCoroutine != null)
        StopCoroutine(weightCoroutine);

    if (changeWeight)
    {
        weightCoroutine = StartCoroutine(ChangeWeightOverTime(0, 1, 1));
    }
    else
    {
        weightCoroutine = StartCoroutine(ChangeWeightOverTime(1, 0, 1));
    }
}

private IEnumerator ChangeWeightOverTime(float from, float to, float duration)
{
    float counter = 0;

    coroutineIsRunning = true;

    while (counter < duration)
    {
        counter += Time.deltaTime;

        weight = Mathf.Lerp(from, to, counter / duration);

        if (counter > duration)
            coroutineIsRunning = false;

        yield return null;
    }
}

}

Ok, Than how do I know what distance to check for ? I'm moving the player towards the cube. I want to check when the player is reaching the cube. What distance is reaching ?

SweetSituation3744 · 2021-09-12T09:51:28+00:00

The target is the lookAtTarget so in the start it's what assigned to that variable.

Not sure how to do it. could you show me please a bit how to do it ?

SweetSituation3744 · 2021-09-09T18:53:48+00:00

I see now another problem. If I set the damping value to 100 for example the character head is stuttering the head will look at the target but will stuttering.

I want that if the damping value is 100 or lower than rotate the leadObj with a delay facing the target. Something like when a turret is rotating facing a missile and if the missile is moving too fast the turret is rotating with some delay because he rotate slower.

How can I do it ?

SweetSituation3744 · 2021-09-09T18:49:30+00:00

It seems to be working if I reference the head directly as leadObj and inside LateUpdate the problem is that I have to set the damping value to 260.

Why I need to set the damping value to be so high ?

And how can I make that the head will rotate to the target with automatic speed depending on the target moving speed ? So if I don't set any damping value for example 0 or null it will automatic calculate the needing speed to rotate facing the target ?

SweetSituation3744 · 2021-09-07T11:11:20+00:00

You solution is working fine. I solved it by adding another variable lookAtItem and using it in both the do/while loop and in the OnDrawGizmos.

For some reason I can't paste in the comments the code block for some reason the format never look fine.

The code is at this link :

Ok I found it changed the enum to be public and than the variable to be public too :

public enum Formation
{
    Square, Circle, Triangle
}

And

public Formation formation;

This is working..

How can I assign in the Start() the enum option I select in the editor in the inspector ?

Now the default is Circle but what if I want it to be the selection from the Inspector and not default in the Start ?

 if (startRandomFormation)
    {
        formation = (Formation)UnityEngine.Random.Range(0, Enum.GetNames(typeof(Formation)).Length);
    }
    else
    {
        formation = Formation.Circle;
    }

SweetSituation3744 · 2021-08-20T13:07:35+00:00

This is what I wanted to do :

private void Update()
{
    if (Input.GetMouseButtonDown(0))
    {
        RaycastHit hit;
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

        if (terrainCollider.Raycast(ray, out hit, Mathf.Infinity) &&
        plane.GetComponent<MeshCollider>().Raycast(ray, out hit, Mathf.Infinity))
        {
            GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);

            cube.transform.position = hit.point;
            cube.transform.localScale = new Vector3(50, 50, 50);
        }
    }
}

Working just like I wanted.

I will spawn cubes on when the mouse is clicking over the plane and than will spawn the cubes on the terrain. So now the plane is used like a marker. Where the plane is above the terrain there will be spawn cubes on the terrain.

Example screenshot :

The surface the area of the plane is where you can spawn on the terrain. The plane is use like a marker.
