ScriptableObject非常适合小数量的游戏数值。
使用ScriptableObject的时候需要注意，生成ScriptableObject数据文件需要自己写Editor代码实现。
大概的工作流程是：写一个ScriptableObject（继承ScriptableObject的类，相当于数据模板） → 使用自己写的Editor代码生成一个实现该模板的数据文件 → Inspector面板中编辑数据。
给出我的Editor代码：
using UnityEngine;
using System.IO;
using System.Collections;
using UnityEditor;
public class Scriptablity : MonoBehaviour {
public static T Create<T> ( string _path, string _name) where T : ScriptableObject {
if ( new DirectoryInfo(_path).Exists == false ) {
Debug.LogError ( "can't create asset, path not found" );
return null;
}
if ( string.IsNullOrEmpty(_name) ) {
Debug.LogError ( "can't create asset, the name is empty" );
return null;
}
string assetPath = Path.Combine( _path, _name + ".asset" );
T newT = ScriptableObject.CreateInstance<T>();
AssetDatabase.CreateAsset(newT, assetPath);
Selection.activeObject = newT;
return newT;
}
public static void Create<T>() where T : ScriptableObject {
string assetName = "New " + typeof(T).Name;
string assetPath = "Assets";
if(Selection.activeObject) {
assetPath = AssetDatabase.GetAssetPath(Selection.activeObject);
if (Path.GetExtension(assetPath) != "")
{
assetPath = Path.GetDirectoryName(assetPath);
}
}
bool doCreate = true;
string path = Path.Combine( assetPath, assetName + ".asset" );
FileInfo fileInfo = new FileInfo(path);
if ( fileInfo.Exists ) {
doCreate = EditorUtility.DisplayDialog( assetName + " already exists.",
"Do you want to overwrite the old one?",
"Yes", "No" );
}
if ( doCreate ) {
T T_info = Create<T> ( assetPath, assetName );
Selection.activeObject = T_info;
}
}
public static void Create() {
Debug.LogError("You should call 'Create' method like this : Create<ExampleData>();");
}
}
使用方法：
1.写个ScriptableObject。
public class Example : ScriptableObject {
public int id;
public string name;
}
2.写个MonoBehavior调用Create方法生成Example格式的数据。
public class ExampleItem: MonoBehaviour {
[MenuItem("Example/Create/Example Data")]
static void CreatExample() {
Scriptablity.Create<Example>();
}
}
3.在Inspector面板编辑数据。
4.使用该数据
public class ExampleUsage : MonoBehavior {
public Example exampleInfo;
void Start()
{
Debug.Log(exampleInfo.name);
}
}
