Multiplatform Runtime Level Editor Extension - Save/Load file picker（另外一个扩展插件）
概要
文件选择器扩展允许您保存和加载多个关卡文件。它包含一个弹出窗口，允许您输入新的文件名或从现有文件中选择一个关卡。（Unity资源商店中这个扩展插件的购买链接）
将关卡上传到Steam Workshop
使用下面的单行代码来激活Steam Workshop关卡的数据库格式。该代码行应该在游戏启动时执行，例如在主脚本的Awake方法中。关卡将保存在包含关卡文件和图标的文件夹中。这是Steam要求的，只有文件夹可以上传到Steam Workshop，无法上传单个文件。
LE_LevelEditor.Extensions.LE_ExtensionInterface.FileSelectionInstance.LevelDB = new LE_LevelEditor.Extensions.LE_LevelDatabase_SteamWorkshop();
完成此操作后，您可以使用Steam Workshop - Easy Steamworks Integration（也是Unity商店的一个插件）来上传和下载关卡。如果要使用文件选择器菜单加载Workshop关卡，请将Steam Workshop项目的根文件夹传递给LE_LevelDatabase_SteamWorkshop类的构造函数。当你想要在你的脚本中的时候可以替换LevelDB属性。
下面的示例脚本将允许玩家选择一个关卡并上传它：
using System.IO;
using UnityEngine;
using LE_LevelEditor.Extensions;
using LE_LevelEditor.UI;
using LevelFile = LE_LevelEditor.Extensions.LE_ExtensionInterface.FileSelectionExtensionLoader.LevelFile;
using LapinerTools.Steam;
using LapinerTools.Steam.UI;
using LapinerTools.Steam.Data;
using LapinerTools.uMyGUI;
// Add this example script to your level editor scene.
// It will change the level folder structure of the saved levels to match Steam Workshop requirements.
// Press F1 while running the scene to upload a level.
public class MRLE_SteamWorkshop_ESI_Example : MonoBehaviour
{
private void Awake()
{
LE_LevelEditor.Extensions.LE_ExtensionInterface.FileSelectionInstance.LevelDB = new LE_LevelEditor.Extensions.LE_LevelDatabase_SteamWorkshop();
}
void Update()
{
if (Input.GetKeyUp(KeyCode.F1))
{
LE_FileSelectionHelpers.SelectLevel(this, "Upload Level", "Which level do you want to upload to Steam Workshop?", (int p_selectedLevelIndex, LevelFile[] p_levelFiles)=>
{
// get Steam item from folder
string levelFolder = Path.GetDirectoryName(p_levelFiles[p_selectedLevelIndex].PathData);
WorkshopItemUpdate itemUpdate = SteamWorkshopMain.Instance.GetItemUpdateFromFolder(levelFolder);
if (itemUpdate == null)
{
// level was never uploaded => prefil the upload dialog
itemUpdate = new WorkshopItemUpdate();
itemUpdate.Name = p_levelFiles[p_selectedLevelIndex].Name;
itemUpdate.IconPath = p_levelFiles[p_selectedLevelIndex].PathIcon;
itemUpdate.ContentPath = levelFolder;
}
// show the Steam Workshop item upload popup
((SteamWorkshopPopupUpload)uMyGUI_PopupManager.Instance.ShowPopup("steam_ugc_upload")).UploadUI.SetItemData(itemUpdate);
});
}
}
}
