Unity 控制UI突出显示然后回归正常

    UI大小默认是targetscale——>突出变大——>再变成targetscale

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class UIcontrol : MonoBehaviour {
	
	private float targetScale = 1f;
	private Vector3 animationScale = new Vector3(1.4f, 1.4f, 1.4f);
	private float smoothing = 4;
	void Update()
	{
		if (transform.localScale.x != targetScale)
		{
			//动画
			float scale = Mathf.Lerp(transform.localScale.x, targetScale,smoothing*Time.deltaTime);
			transform.localScale = new Vector3(scale, scale, scale);
			if (Mathf.Abs(transform.localScale.x - targetScale) < .02f)
			{    
				transform.localScale = new Vector3(targetScale, targetScale, targetScale);
			}
		}
	}
	public void Big()
	{

		transform.localScale=animationScale;
	}
