Unity 場景匯出XML或JSON二進位制並且解析還原場景
場景匯出XML或JSON二進位制並且解析還原場景
首次按自己先找一個Scene或者自己做一個也可以。我就是自己做一個。
然後給Sphere新增一個指令碼（Sphere圍繞著cube運動）：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Move : MonoBehaviour {
public GameObject MySphere;
private float speed = 3;
public Vector3[] myPosition;
int index;
// Use this for initialization
void Start () {
index = 0;
}
// Update is called once per frame
void Update () {
MySphere.transform.position = Vector3.MoveTowards(MySphere.transform.position,myPosition[index],speed*Time.deltaTime);
if (MySphere.transform.position==myPosition[index])
{
index++;
}
if (index==4)
{
index = 0;
}
}
}
一個小場景就做好了。
接下在就是把把場景轉換成二進位制的json和xml格式。（不懂的可以看雨鬆的文章，寫的非常詳細和不錯哦）
MyEditor指令碼（放入Editor資料夾）：
using UnityEngine;
using System.Collections;
using UnityEditor;
using System.Collections.Generic;

//遍歷所有的遊戲場景
foreach (UnityEditor.EditorBuildSettingsScene S in UnityEditor.EditorBuildSettings.scenes)

//開啟這個關卡

xmlDoc.AppendChild(root);
xmlDoc.Save(filepath);

}
}
}
//重新整理Project檢視， 不然需要手動重新整理哦
AssetDatabase.Refresh();

//將所有遊戲場景匯出為JSON格式

放進去後可以看到：
然後別忘記把場景新增到Buildsetting裡面（需要copy的場景）。
匯出來的檔案放入到：
Xml（指令碼）：
using UnityEngine;
using System.Collections;
using System.Xml;
using System.IO;
using UnityEngine.SceneManagement;
public class XML : MonoBehaviour
{
// Use this for initialization
void Start()
{
//電腦和iphong上的路徑是不一樣的，這裡用標籤判斷一下。
//#if UNITY_EDITOR
string filepath = Application.dataPath + "/StreamingAssets" + "/my.xml";//#elif UNITY_IPHONE
// string filepath = Application.dataPath +"/Raw"+"/my.xml";
//#endif
//如果檔案存在話開始解析。
if (File.Exists(filepath))
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(filepath);
XmlNodeList nodeList = xmlDoc.SelectSingleNode("gameObjects").ChildNodes;
foreach (XmlElement scene in nodeList)
{
//因為我的XML是把所有遊戲物件全部匯出， 所以這裡判斷一下只解析需要的場景中的遊戲物件
//JSON和它的原理類似
if (!scene.GetAttribute("name").Equals("Assets/MySceneOne.unity"))
{
continue;// 獲取屬性 GetAttribute
}
foreach (XmlElement gameObjects in scene.ChildNodes)
{
string asset = "Prefab/" + gameObjects.GetAttribute("name");
Vector3 pos = Vector3.zero;
Vector3 rot = Vector3.zero;
Vector3 sca = Vector3.zero;
foreach (XmlElement transform in gameObjects.ChildNodes)
{
foreach (XmlElement prs in transform.ChildNodes)
{
if (prs.Name == "position")
{
foreach (XmlElement position in prs.ChildNodes)
{
switch (position.Name)
{
case "x":
pos.x = float.Parse(position.InnerText);
break;
case "y":
pos.y = float.Parse(position.InnerText);
break;
case "z":
pos.z = float.Parse(position.InnerText);
break;
}
}
}
else if (prs.Name == "rotation")
{
foreach (XmlElement rotation in prs.ChildNodes)
{
switch (rotation.Name)
{
case "x":
rot.x = float.Parse(rotation.InnerText);
break;
case "y":
rot.y = float.Parse(rotation.InnerText);
break;
case "z":
rot.z = float.Parse(rotation.InnerText);
break;
}
}
}
else if (prs.Name == "scale")
{
foreach (XmlElement scale in prs.ChildNodes)
{
switch (scale.Name)
{
case "x":
sca.x = float.Parse(scale.InnerText);
break;
case "y":
sca.y = float.Parse(scale.InnerText);
break;
case "z":
sca.z = float.Parse(scale.InnerText);
break;
}
}
}
}
//拿到 旋轉 縮放 平移 以後克隆新遊戲物件
GameObject ob = (GameObject)Instantiate(Resources.Load(asset), pos, Quaternion.Euler(rot));
ob.transform.localScale = sca;
}
}
}
}
}
}
Json指令碼：
using UnityEngine;
using System.Collections;
using System.IO;
using LitJson;
using UnityEngine.SceneManagement;
public class JSON : MonoBehaviour
{
// Use this for initialization
void Start()
{
//#if UNITY_EDITOR
string filepath = Application.dataPath + "/StreamingAssets" + "/json.txt";
//#elif UNITY_IPHONE
// string filepath = Application.dataPath +"/Raw"+"/json.txt";
//#endif
StreamReader sr = File.OpenText(filepath);
string strLine = sr.ReadToEnd();
JsonData jd = JsonMapper.ToObject(strLine);
JsonData gameObjectArray = jd["GameObjects"];
int i, j, k;
for (i = 0; i < gameObjectArray.Count; i++)
{
JsonData senseArray = gameObjectArray[i]["scenes"];
for (j = 0; j < senseArray.Count; j++)
{
string sceneName = (string)senseArray[j]["name"];
if (!sceneName.Equals("MySceneOne.unity"))
{
continue;
}
JsonData gameObjects = senseArray[j]["gameObject"];
for (k = 0; k < gameObjects.Count; k++)
{
string objectName = (string)gameObjects[k]["name"];
string asset = "Prefab/" + objectName;
Vector3 pos = Vector3.zero;
Vector3 rot = Vector3.zero;
Vector3 sca = Vector3.zero;
JsonData position = gameObjects[k]["position"];
JsonData rotation = gameObjects[k]["rotation"];
JsonData scale = gameObjects[k]["scale"];
pos.x = float.Parse((string)position[0]["x"]);
pos.y = float.Parse((string)position[0]["y"]);
pos.z = float.Parse((string)position[0]["z"]);
rot.x = float.Parse((string)rotation[0]["x"]);
rot.y = float.Parse((string)rotation[0]["y"]);
rot.z = float.Parse((string)rotation[0]["z"]);
sca.x = float.Parse((string)scale[0]["x"]);
sca.y = float.Parse((string)scale[0]["y"]);
sca.z = float.Parse((string)scale[0]["z"]);
GameObject ob = (GameObject)Instantiate(Resources.Load(asset), pos, Quaternion.Euler(rot));
ob.transform.localScale = sca;
}
}
}
}
}
執行之後就可以載入了。西面效果圖：
最後別忘記把資源Prefab放入到Reasources資料夾裡面：
