unity 保存场景数据,读取场景
一共两个脚本
一个保存的,一个读取的,下面会附上代码,网上都有,这个只是方便自己用,
这是保存的脚本,放到Editor文件夹下即可
using System.Collections; using System.Collections.Generic; using System.IO; using System.Xml; using UnityEditor; using UnityEditor.SceneManagement; using UnityEngine; // <summary> /// 保存所有的游戏场景,每个场景的数据都会保存到XML,网上都有,只是方便自己用. /// </summary> public class ExportSceneInfoToXML : Editor { [MenuItem("GameObject/ExportXML")] static void ExportXML() { string filepath = Application.dataPath + @"/StreamingAssets/my.xml"; if (!File.Exists(filepath)) { File.Delete(filepath); } XmlDocument xmlDoc = new XmlDocument(); XmlElement root = xmlDoc.CreateElement("gameObjects"); //遍历所有的游戏场景 foreach (UnityEditor.EditorBuildSettingsScene S in UnityEditor.EditorBuildSettings.scenes) { //当场景启用 if (S.enabled) { //得到场景的名称 string name = S.path; //打开这个场景 EditorApplication.OpenScene(name); XmlElement scenes = xmlDoc.CreateElement("scenes"); scenes.SetAttribute("name", name); foreach (GameObject obj in Object.FindObjectsOfType(typeof(GameObject))) { if (obj.transform.parent == null) { XmlElement gameObject = xmlDoc.CreateElement("gameObjects"); gameObject.SetAttribute("name", obj.name); gameObject.SetAttribute("asset", obj.name + ".prefab"); XmlElement transform = xmlDoc.CreateElement("transform"); XmlElement position = xmlDoc.CreateElement("position"); XmlElement position_x = xmlDoc.CreateElement("x"); position_x.InnerText = obj.transform.position.x + ""; XmlElement position_y = xmlDoc.CreateElement("y"); position_y.InnerText = obj.transform.position.y + ""; XmlElement position_z = xmlDoc.CreateElement("z"); position_z.InnerText = obj.transform.position.z + ""; position.AppendChild(position_x); position.AppendChild(position_y); position.AppendChild(position_z); XmlElement rotation = xmlDoc.CreateElement("rotation"); XmlElement rotation_x = xmlDoc.CreateElement("x"); rotation_x.InnerText = obj.transform.rotation.eulerAngles.x + ""; XmlElement rotation_y = xmlDoc.CreateElement("y"); rotation_y.InnerText = obj.transform.rotation.eulerAngles.y + ""; XmlElement rotation_z = xmlDoc.CreateElement("z"); rotation_z.InnerText = obj.transform.rotation.eulerAngles.z + ""; rotation.AppendChild(rotation_x); rotation.AppendChild(rotation_y); rotation.AppendChild(rotation_z); XmlElement scale = xmlDoc.CreateElement("scale"); XmlElement scale_x = xmlDoc.CreateElement("x"); scale_x.InnerText = obj.transform.localScale.x + ""; XmlElement scale_y = xmlDoc.CreateElement("y"); scale_y.InnerText = obj.transform.localScale.y + ""; XmlElement scale_z = xmlDoc.CreateElement("z"); scale_z.InnerText = obj.transform.localScale.z + ""; scale.AppendChild(scale_x); scale.AppendChild(scale_y); scale.AppendChild(scale_z); transform.AppendChild(position); transform.AppendChild(rotation); transform.AppendChild(scale); gameObject.AppendChild(transform); scenes.AppendChild(gameObject); root.AppendChild(scenes); xmlDoc.AppendChild(root); xmlDoc.Save(filepath); } } } } //刷新Project视图， 不然需要手动刷新哦 AssetDatabase.Refresh(); } }
这是读取场景的脚本,挂在场景的空物体上即可
