在 unity 和 vuforia 中重置图像目标中模型的缩放比例

I'm using Vuforia and unity for my AR App. which has more than 2 models/image targets. To zoom in and out I used Lean Touch. But the problem is both will get zoom on pinching . I want only one to zoom which is currently detected.. OR I want reset Scale component of my 3D model/models on OnTrackingLost() function in DefaultTrackableEventHandler so that when it detects other one it shows on original scale (as i set max sim images detected to one). Thanks !

EDIT :

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

public class rscale : MonoBehaviour {

    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {
        if (Input.GetKey (KeyCode.V)) {
            transform.localScale = new Vector3 (4f, 4f, 4f);
            Debug.Log("scaling to 4");
        }
    }
}

但这个简单的脚本也不起作用？

您进行缩放的方法，添加：

if(this.gameObject.activeSelf == false){ return; }
// Scaling process

因此，如果您在所有对象上运行代码，则只有活动对象才会受到影响。考虑到您在丢失跟踪时停用对象。
