Increase/Decrease Object Scale

[oliver-jones]

Hello,

I want to be able to smoothly increase/decrease the scale.y of my object.

Basically, I have a variable that will randomly range between 1 and 10 every second, and I want this variable to effect the scale.y of a certain object.

In other words, if var random = 5, then scale.y will also =5, if the var random changes to, say 8, then scale.y will smoothly/gradually increase to 8 too.

How will this be achieved? Lerp?

Here is where I’m at:

function Start(){
    
    while(true){
        oldScale = sizeY;
        sizeY = Random.Range(1, 11);
        newScale = sizeY;

        yield WaitForSeconds(0.2);
    }
}

private var speed : float = 1;

var oldScale : int;
var newScale : int;

var oldScaleVec : Vector3;
var newScaleVec : Vector3;

function Update (){

    oldScaleVec = Vector3(1, oldScale, 1);
    newScaleVec = Vector3(1, newScale, 1);

     cube.transform.localScale = Vector3.Lerp(oldScaleVec, newScaleVec, Time.deltaTime / 2);

}

This kind of works, although it’s not animating it - more like jumping straight to the new given value.

float newScale;
float ratio;

void Start(){
    ratio = Time.deltaTime;
    InvokeRepeating("ChangeScale",1f,1f);
}

void Update(){
    float newVal = Mathf.Lerp(transform.localScale.y,newScale,ratio);
    transform.localScale = new Vector3(transform.localScale.x,newVal,transform.localScale.z);
}

void ChangeScale(){
    newScale = Random.Range(0f,10f);
}
