1. // C#
2. transform.localScale = new Vector3(transform.localScale.x * 2, transform.localScale.y * 2, transform.localScale.z * 2);

1. // JS
2. transform.localScale = Vector3(transform.localScale.x * 2, transform.localScale.y * 2, transform.localScale.z * 2);

----例----

using UnityEngine;
using System.Collections;

public class FlowerShrinkScript_C : MonoBehaviour
{
    public float targetScale = 0.1f;
    public float shrinkSpeed = 0.001f;
    public bool shrinking = false;

    // Use this for initialization
    void Start ()
    {
        shrinking = true;
    }

    // Update is called once per frame
    void Update ()
    {
        if (transform.localScale.x > targetScale) {
            transform.localScale -= new Vector3 (shrinkSpeed, shrinkSpeed, 0);
