Unity 手动拆分和组装模型

第一次写博客，不足之处还望前辈指点：

         项目需求是需要用Unity制作船舰模型的爆炸图效果。我的思路是先把船舰上各个单元组件的位置记录下来，然后依次移动这些单元组件的位置，在复原该模型时，再把原来记录的单元组成模型位置还原出来。

       首先，在Hierarchy面板新建一个GameObject，创建4个Sphere和一个Cube用来搭建一个小车模型（(#^.^#)我家小车是球形轱辘哦）；

      第一步在Assets文件夹下面创建一个Scripts,然后添加一个DateVO和PartVO脚本

       using UnityEngine;using System.Collections;[System.Serializable]public class PartVO { public Vector3 pos; public Vector3 rot; public Vector3 scale;}

      第二步创建拖拽脚本Drag

       using UnityEngine;using System.Collections;public class Drag : MonoBehaviour {private IEnumerator OnMouseDown() { Vector3 pos = Camera.main.WorldToScreenPoint(transform.position); Vector3 offset = transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y,pos.z)); while (Input.GetMouseButton(0)) { transform.position = Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, pos.z))+offset; yield return new WaitForFijiaoxedUpdate(); } }}

      第三步创建复原脚本ReaetPart

          using UnityEngine;using System.Collections;using System;using System.IO;public class ResetPart : MonoBehaviour { string path; string s; GameObject part;// Use this for initializationvoid Start () { part = GameObject.Find("Part"); path = Application.dataPath + "/PartMessage.json";}// Update is called once per framevoid Update () { if (Input.GetMouseButtonDown(1)) { Reset(); }} private void Reset() { if (!File.Exists(path)) { throw new Exception("找不到当前的路径"); } s = File.ReadAllText(path); DateVO date = JsonUtility.FromJson<datevo>(s); for(int i = 0; i < part.transform.childCount; i++) { part.transform.GetChild(i).localPosition = date.parts[i].pos; part.transform.GetChild(i).localEulerAngles = date.parts[i].rot; part.transform.GetChild(i).localScale = date.parts[i].scale; } }}

     最后我写了一个JSON存模型单元组件位置的脚本PartCreateMessage

using UnityEngine;using System.Collections;using System.IO;using UnityEditor;public class PartCreateMessage : MonoBehaviour { [MenuItem("Tools/CreateJSON")] static void WriteJson() { string path = Application.dataPath + "/PartMessage.json"; GameObject obj = Selection.activeGameObject; if (obj.name != "Part") { throw new System.Exception("Selection Model"); } DateVO date = new DateVO(); for(int i = 0; i < obj.transform.childCount; i++) { PartVO part = new PartVO(); part.pos = obj.transform.GetChild(i).localPosition; part.rot = obj.transform.GetChild(i).localEulerAngles; part.scale = obj.transform.GetChild(i).localScale; date.parts.Add(part); } string s = JsonUtility.ToJson(date); File.WriteAllText(path,s); AssetDatabase.Refresh(); }}
