Scale object for short time

Scripting
1

Hey guys,

so that’s my script:

public class Scale : MonoBehaviour {

Vector3 temp;

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
temp = transform.localScale;
temp.y += 1f;
temp.x += 1f;
transform.localScale = temp;
}
}

a simple script to scale an object. What I want to add is: after like 0.2 seconds the scaling should stop and go back to its standard size of the cube. How am I gonna implement that?

You should look into Coroutines, and please, use code tags.

Here’s something I made a while ago when I was bored. Just place it on a cube with a collider.

    public float LerpTime = 3f;
    public Vector3 ScaleTo = new Vector3(3f, 3f, 3f);

    private bool _coroutineRunning; //Just to prevent odd behavior if user clicks object during lerptime

    public void Update ()
    {
        if(Input.GetMouseButtonDown(0) && !_coroutineRunning)
        {
            Debug.Log("Clicked!");
            StartCoroutine(scaleCube(LerpTime, ScaleTo));          
        }
    }

    private IEnumerator scaleCube(float lerpTime, Vector3 scale)
    {
        _coroutineRunning = true;
        Vector3 currentScale = transform.localScale;
        float elapsedTime = 0f;
        //Gradually exapnd object
        while (elapsedTime < lerpTime)
        {
            transform.localScale = Vector3.Lerp(currentScale, scale, (elapsedTime / lerpTime));
            elapsedTime += Time.deltaTime;
            yield return null;
        }

        elapsedTime = 0f;
        //Gradually contract object to original size
        while (elapsedTime < lerpTime)
        {
            transform.localScale = Vector3.Lerp(scale, currentScale, (elapsedTime / lerpTime));
            elapsedTime += Time.deltaTime;
            yield return null;
        }
        //Just to eliminate any floating point errors and ensure the object returns to its original size
        transform.localScale = currentScale;
        _coroutineRunning = false;
    }
