Unity3D 中的简单 Steam 创意工坊实现

添加 Steamworks 软件包

1. 转到 https://github.com/rlabrecque/Steamworks.NET/releases 并下载最新版本，确保下载 .unitypackage。然后，您需要将其导入您的 Unity 项目。

2. 在项目文件夹的根目录中打开 steam_appid.txt 文件并将 480 替换为您的 Steam AppId。重新启动 Unity。

3. 在您的初始场景中，创建一个新游戏对象，将其命名为“Steam Manager”，并添加在 Scripts>Steamworks.NET 中找到的 SteamManager.cs 脚本

这就是将 Steamworks 集成到您的项目中所需的全部内容。只要确保 Steam 客户端在后台运行，您应该能够在编辑器中点击播放并且没有错误。
