如何在Untiy中使用AnimationCurve曲线

using System.Collections;
using UnityEngine;

public class UseAnimationCurve: MonoBehaviour
{
//创建一个AnimationCurve
[SerializeField]
private AnimationCurve curve;
//在多少秒内完成变化（总时间）
[SerializeField]
private float totalTime;

private void Update()
{
    if (Input.GetKeyDown(KeyCode.Space))
    {
        StartCoroutine(StartCurve());
    }
}
private IEnumerator StartCurve()
{
    float time = 0;
    while(time <= totalTime)
    {
        float normalizeTime = (time / totalTime);
        time += Time.deltaTime;
        float curveValue = curve.Evaluate(normalizeTime);
        Debug.Log(curveValue);
        transform.localScale = new Vector3(curveValue, curveValue, curveValue);
        yield return null;
    }
}

}
