c#的控制部分代码：

using UnityEngine;using System.Collections;public class _3Dprinter : MonoBehaviour {    private Material mat;    public float timer = 0;    public float value = 1;    void Start()    {        mat = GetComponent<MeshRenderer>().material;    }    void Update()    {        timer += Time.deltaTime;        if (timer > 0.1f)        {            if (value <= 3)            {                mat.SetFloat("_ConstructY", value += 0.05f);                timer = 0;            }        }    }}
