这里使用的是unity.1
对于unity编辑器开发也不是很了解，这方面的教程也不多，也是慢慢摸索的
效果显示
首先简单
介绍下Unity编辑器开发
1:Editor下打开新窗口需要继承EditorWindow,然后使用获取窗口即可,注意放在Editor文件夹下
public class DrawGameLevel : EditorWindow{[MenuItem("Maps/Create Map &M")]public static void OpenMapCreate(){DrawGameLevel window = EditorWindow.GetWindow<DrawGameLevel>("地图编辑器");window.Show();window.minSize = new Vector2(500, 800);window.maxSize = new Vector2(600, 1200);}}
2:因为是在Scene视图下进行操作,所以注册SceneView.duringSceneGui事件,在OnEnable中
void OnEnable()2{3 SceneView.duringSceneGui += OnSceneGUI;4 //初始化一些东西5}6 7void OnDestroy()8{9 SceneView.duringSceneGui -= OnSceneGUI;10}
3:unity编辑器开发，需要在GUI中写，使用EditorGUILayout或者GUILayout来显示ui,基本的组件都是有的
这是我实现的界面和代码
#region GUI显示private string brushY = "";// 刷新的y坐标private string brushX = "";// 刷新的x坐标private string brushDisY = "0";// 刷新的y坐标间距private string brushDisX = "0";// 刷新的x坐标间距private string zIndex = "-0.2";// 显示的层级private string fixCount = "0";// 固定生成个数，设置0，一直生成private float _lastBrushY = -10000;// 保持Y合理间距 上次刷的y的坐标private float _lastBrushX = -10000;// 保持X合理间距 上一个刷的x的坐标private int _curImgIndex = -1;//当前正在使用的图private int _curFixCount = 0;// 当前已经生成的个数private bool _drag = false;// 鼠标拖拽？private int _select = 0;// 当前选择的图片 indexprivate string ck = "1";// 关卡private Texture[] _items = null;// 地形基础图 要使用的地块private GameObject parentMap = null;// 地图节点的父节点private GameObject bgParent = null;// 背景图挂点private string[] bgNames = { "Forest", "Night", "Winter" };// 背景图名字private int selectMapIndex = 0;// 选择的地图背景图indexprivate int lastSelectMapIndex = -1;// 上次选择的地图背景图indexprivate int funcTypeIndex = 0;// 功能类型的indexprivate string[] funcTypeArry = { "无","橡皮擦","选中单个物体"};// 选择单个物体private int selectTypeIndex = 0;private int lastSelectTypeIndex = 0;// 上次选择的类型private string[] typeArry = {"不显示选图", "地形图","障碍物",};// Update is called once per framevoid OnGUI(){GUI.skin.label.normal.textColor = Color.yellow;GUI.skin.label.fontSize = 15;GUIStyle popStyle = new GUIStyle("Popup");popStyle.fontSize = 15;// 选择地图EditorGUILayout.Space();EditorGUILayout.BeginHorizontal();GUILayout.Label("1.选择地图", GUILayout.Width(200));this.selectMapIndex = EditorGUILayout.Popup(this.selectMapIndex, bgNames, popStyle, GUILayout.MaxWidth(100));EditorGUILayout.EndHorizontal();EditorGUILayout.Space();LoadBg(); ck = EditorGUILayout.TextField("2.设置关卡", ck);// 输入数据EditorGUILayout.Space();GUILayout.Label("设置坐标，批量坐标保持一致的时候使用，不输入是按照鼠标位置刷新");brushY = EditorGUILayout.TextField("3.固定Y的坐标(从左到右刷)", brushY);brushX = EditorGUILayout.TextField("4.固定X的坐标(从上到下刷)", brushX);brushDisY = EditorGUILayout.TextField("5.固定Y间距(从左到右刷)", brushDisY);brushDisX = EditorGUILayout.TextField("6.固定X间距(从上到下刷)", brushDisX);fixCount = EditorGUILayout.TextField("7.固定生成的个数", fixCount);EditorGUILayout.Space(10);zIndex = EditorGUILayout.TextField("8.物体显示层级，小的靠前显示", zIndex);EditorGUILayout.Space();EditorGUILayout.BeginHorizontal();GUILayout.Label("9.选择橡皮擦 或者 选中一个场景物体", GUILayout.Width(250));this.funcTypeIndex = EditorGUILayout.Popup(this.funcTypeIndex, funcTypeArry, popStyle, GUILayout.MaxWidth(100));EditorGUILayout.EndHorizontal();EditorGUILayout.Space();EditorGUILayout.BeginHorizontal("box");GUIStyle btnStyle = new GUIStyle("Button");btnStyle.fontSize = 15;btnStyle.padding = new RectOffset(10, 10, 10, 10);if (GUILayout.Button("10.清除当前地图数据",btnStyle)){RemoveParentChild(parentMap);_lastBrushY = -10000;// 防止后面刷新跟着这个位置_lastBrushX = -10000;_curFixCount = 0;}if (GUILayout.Button("11.导出json数据",btnStyle)){DataMgr.Instance.OutFile(parentMap,ck);EditorUtility.DisplayDialog("导出数据成", "导出关卡数据成功"+ck, "确定");}if (GUILayout.Button("12.导入json数据",btnStyle)){DataMgr.Instance.ImportFile(parentMap,ck);EditorUtility.DisplayDialog("导入数据成功","导入关卡数据成功"+ck,"确定");}EditorGUILayout.EndHorizontal();// 选择图片类型GUILayout.Label("13.显示选图", GUILayout.Width(200));this.selectTypeIndex = EditorGUILayout.Popup(this.selectTypeIndex,typeArry, popStyle, GUILayout.MaxWidth(100));if (selectTypeIndex>0) LoadChooseImg();// 加载选图}#endregion
4:unity编辑器开发，资源加载可以使用Resources,前提是需要把资源放到Editor->Resources中
5：地图文件导出和导入，通过FileStream和LitJson的解析实现的
using System;using System.Collections.Generic;using System.IO;using System.Linq;using System.Text;using LitJson;using UnityEngine;using UnityEditor;// 障碍物public class Obstacle{public int id;public string name;public int type;}// 导出的地图json文件数据格式public class DataFile{public int id;public string name; // 预制体名字public string path; // 加载路径public string tag;// 预制体的tagpublic string posX;// 坐标xpublic string posY;// 坐标ypublic string posZ;// 坐标zpublic string scaX;// scale xpublic string scaY;// scale ypublic string scaZ;// scale zpublic string rotX;// rotate xpublic string rotY;// rotate y public string rotZ;// rotate z// Todo，后面还可以加障碍物id，用于实现障碍物的功能public DataFile() { }public DataFile(int id1,string path1,string tag1, float px, float py, float pz, float sx, float sy, float sz, float rx, float ry, float rz){id = id1;path = path1;string[] p = path.Split('/');name = p[p.Length - 1];tag = tag1;posX = px.ToString();posY = py.ToString();posZ = pz.ToString(); // 使用string类型，是因为转json不识别float和double scaX = sx.ToString();scaY = sy.ToString();scaZ = sz.ToString();rotX = rx.ToString();rotY = ry.ToString();rotZ = rz.ToString();}}public class DataMgr:Editor{private static DataMgr instance = null;public static DataMgr Instance{get{if (null == instance) instance = new DataMgr();return instance;}}public readonly List<Obstacle> m_table = null;public DataMgr(){// 注册json类型转换方法LitJson.JsonMapper.RegisterImporter<int, string>((int input) => { return input.ToString(); });LitJson.JsonMapper.RegisterImporter<string, int>((string input) => { return Convert.ToInt32(input); });// 加载障碍物表 //TextAsset ts = Resources.Load<TextAsset>("jsonTable/config_obstacle");//m_table = JsonMapper.ToObject<List<Obstacle>>(ts.text);}// 导出文件json// ck 关卡idpublic void OutFile(GameObject parent,string ck){int childCount = parent.transform.childCount;if (childCount <= 0){Debug.Log("没有可以导出的数据节点");}List<DataFile> list = new List<DataFile>();for (int i = 0; i < childCount; i++){GameObject obj = parent.transform.GetChild(i).gameObject;DataFile file = new DataFile(i+1,obj.name,obj.tag,obj.transform.localPosition.x, obj.transform.localPosition.y, obj.transform.localPosition.z, obj.transform.localScale.x, obj.transform.localScale.y,obj.transform.localScale.z, obj.transform.localRotation.x, obj.transform.localRotation.y,obj.transform.localRotation.z);list.Add(file);}string jsons = JsonMapper.ToJson(list);FileStream fs = new FileStream(Application.dataPath + "/OutMap/mapCk_"+ck+".json", FileMode.Create);//存储时时二进制,所以这里需要把我们的字符串转成二进制byte[] bytes = new UTF8Encoding().GetBytes(jsons);fs.Write(bytes, 0, bytes.Length);//每次读取文件后都要记得关闭文件fs.Close();Debug.Log("导出成功"+ "/OutMap/mapCk_"+ck +".json");}// 导入文件 实例化数据public void ImportFile(GameObject parent,string ck){if (!parent) return;FileStream fs = new FileStream(Application.dataPath + "/OutMap/mapCk_" + ck + ".json", FileMode.Open);byte[] bytes = new byte[fs.Length];fs.Read(bytes, 0, bytes.Length);//将读取到的二进制转换成字符串string s = new UTF8Encoding().GetString(bytes);List<DataFile> list = JsonMapper.ToObject<List<DataFile>>(s);if (list.Count <= 0){Debug.Log("没有可导入的数据" + "/OutMap/mapCk_" + ck + ".json");return;}UnityEngine.Object a = Resources.Load<GameObject>(list[0].path);for (int i = 0; i < list.Count; i++){if (a.name != list[i].path){// 实例化新的a = Resources.Load<GameObject>(list[i].path);}GameObject obj = Instantiate(a) as GameObject;obj.tag = list[i].tag;obj.name = list[i].path;obj.transform.parent = parent.transform;obj.transform.localPosition = new Vector3(Convert.ToSingle(list[i].posX), Convert.ToSingle(list[i].posY), Convert.ToSingle(list[i].posZ));obj.transform.localRotation = Quaternion.Euler(Convert.ToSingle(list[i].rotX), Convert.ToSingle(list[i].rotY), Convert.ToSingle(list[i].rotZ));obj.transform.localScale = new Vector3(Convert.ToSingle(list[i].scaX), Convert.ToSingle(list[i].scaY), Convert.ToSingle(list[i].scaZ));}Debug.Log("导入成功" + "/OutMap/mapCk_" + ck + ".json");}}
