Unity脚本仅一次创建资产

Question

I'm trying to make a TCG (trading card game) in Unity as an University assignment. I have some scriptable objects to create different types of cards. The problem is I have 600+ cards so it would be nice to have a script that creates a card asset for every card and sets their parameters(load images, texts).

Is there any way to achieve this? It is important that the script runs only once, not every time I open the editor or I start a new instance of the game.

You can implement a method that is only called via a specific button in the UnityEditor that generates all your assets using the MenuItem attribute:

#if UNITY_EDITOR

    using System.IO;
    using UnityEditor;
    using UnityEngine;

    public static class YourExtensions
    {
        [MenuItem("YourMenu/GenerateAssets")]
        private static void GenerateAssets()
        {
            // TODO Get and parse required information e.g. from Database / Xml or Text file
            // I'ld simply make a new class for that like "CardInformation"

            // List<CardInformation>() cardlist = new List<CardInformation>();


            // Somehow receive your information
            // cardlist.add(new CardInformation(parameters));



            // TODO Generate Scriptableobjects

            // foreach(var cardInfo in cardlist){
                    YourScriptableObjectClass asset = ScriptableObject.CreateInstance<YourScriptableObjectClass > ();

                    string path = AssetDatabase.GetAssetPath (Selection.activeObject);
                    if (path == "") 
                    {
                        path = "Assets";
                    } 
                    else if (Path.GetExtension (path) != "") 
                    {
                        path = path.Replace (Path.GetFileName (AssetDatabase.GetAssetPath (Selection.activeObject)), "");
                    }

                    string assetPathAndName = AssetDatabase.GenerateUniqueAssetPath (path + "/New " + typeof(YourScriptableObjectClass ).ToString() + ".asset");

                    AssetDatabase.CreateAsset (asset, assetPathAndName);

                    AssetDatabase.SaveAssets ();
                    AssetDatabase.Refresh();
                    EditorUtility.FocusProjectWindow ();
                    Selection.activeObject = asset;

                    // TODO here set your passed parameters for this asset
                    // asset.parameter = cardInfo.parameters;
            // end foreach
        }

    }

#endif

Source for AssetCreation: CreateScriptableObjectAsset

This method will never be called unless you click the Button in the top Menubar of the Unity Editor.

Note: You can skip the #if UNITY_EDITOR pre-processors if you simply place that script into a folder called Editor . Those scripts are automatically excluded from any build.
