独立游戏如何对接STEAM SDK

独立开发者在对接STEAM SDK之前 首先得先登上青睐之光，也就是我们俗称的“绿光”

一般要先对接G胖家的SDK，然后提交版本，最后等待审核。。。

我本身是unity 开发，对C++也是糊里糊涂..所以这里主要围绕unity说下我对接SDK的一些经历

-----------------------------------------------------------------------------------------------------

第一步：

安装 Steamwork.NET(这里要感谢外国小哥)

1.下载 .unitypackage Stable (7.0.0) 或者从 Github 克隆

2.导入下载的所有文件到项目 Assets/ 目录下.

3.打开unity项目，会自动生成steam_appid.txt到项目的主目录下.

4.打开 steam_appid.txt 并将 480 修改为自己的 AppId.

5.更改脚本 SteamManager.cs 找到  SteamAPI.RestartAppIfNecessary(AppId_t.Invalid)将AppId_t.Invalid替换成(AppId_t)480" 或者 "new AppId_t(480)，480改成自己的APP ID如图：

			if (SteamAPI.RestartAppIfNecessary(new AppId_t(55220))) {
				Application.Quit();
				return;
			}

6.Steam根据提示修改重启unity，保证 steam_appid.txt 已生效.

7.重启unity，保证 steam_appid.txt 已生效.

8.安装sdk完成.

如何使用

1.下载SteamManagers.cs

2.将SteamManager.cs脚本挂在GameObject上，steam会自动生成单例

3.完整C#接口请点击查看

完整SteamManager：

// The SteamManager is designed to work with Steamworks.NET
// This file is released into the public domain.
// Where that dedication is not recognized you are granted a perpetual,
// irrevokable license to copy and modify this files as you see fit.
//
// Version: 1.0.5

using UnityEngine;
using System.Collections;
using Steamworks;

//
// The SteamManager provides a base implementation of Steamworks.NET on which you can build upon.
// It handles the basics of starting up and shutting down the SteamAPI for use.
//

	private static SteamManager s_instance;
	private static SteamManager Instance {

	}

	private bool m_bInitialized;
	public static bool Initialized {
		get {
			return Instance.m_bInitialized;
		}
	}

	private SteamAPIWarningMessageHook_t m_SteamAPIWarningMessageHook;

		if (s_instance != null) {
			Destroy(gameObject);

			// You should never call Steamworks functions in OnDestroy, always prefer OnDisable if possible.
			throw new System.Exception("Tried to Initialize the SteamAPI twice in one session!");
		}

		// We want our SteamManager Instance to persist across scenes.
		DontDestroyOnLoad(gameObject);

		if (!Packsize.Test()) {

			// Steam client and also launches this game again if the User owns it. This can act as a rudimentary form of DRM.

			// Once you get a Steam AppID assigned by Valve, you need to replace AppId_t.Invalid with it and
			// remove steam_appid.txt from the game depot. eg: "(AppId_t)480" or "new AppId_t(480)".

		// Initialize the SteamAPI, if Init() returns false this can happen for many reasons.

	// OnApplicationQuit gets called too early to shutdown the SteamAPI.
	// Because the SteamManager should be persistent and never disabled or destroyed we can shutdown the SteamAPI here.

第二步：

如何提交游戏版本

在提交游戏之前先对 内容上传软件 进行配置：

1、找到sdk\tools\ContentBuilder\scripts目录，该目录下有两个配置文件名需要更改

   app_build_自己的APPID.vdf,  depot_build_自己的APPID.vdf

 2、假如我的APP ID 为 "55220"  ，修改app_build_55220，"appid","depots"内容如下：

"appbuild"
{
	"appid"	"55220"
	"desc" "Your build description here" // description for this build
	"buildoutput" "..\output\" // build output folder for .log, .csm & .csd files, relative to location of this file
	"contentroot" "..\content\" // root content folder, relative to location of this file
	"setlive"	"" // branch to set live after successful build, non if empty
	"preview" "0" // to enable preview builds
	"local"	""	// set to flie path of local content server 
	
	"depots"
	{
		"55221" "depot_build_55221.vdf"
	}
}

修改depot_build_55221，修改 "DepotID" ,"ContentRoot","LocalPath" 内容如下：

"DepotBuildConfig"
{
	// Set your assigned depot ID here
	"DepotID" "55221"

	// Set a root for all content.
	// All relative paths specified below (LocalPath in FileMapping entries, and FileExclusion paths)
	// will be resolved relative to this root.
	// If you don't define ContentRoot, then it will be assumed to be
	// the location of this script file, which probably isn't what you want
	"ContentRoot"	"D:\SDK硬盘位置\steamworks_sdk_138a\sdk\tools\ContentBuilder\content\" 

	// include all files recursivley
  "FileMapping"
  {
  	// This can be a full path, or a path relative to ContentRoot	
    "LocalPath" ".\windows_content\*"
    
    // This is a path relative to the install folder of your game
    "DepotPath" "."
    
    // If LocalPath contains wildcards, setting this means that all
    // matching files within subdirectories of LocalPath will also
    // be included.
    "recursive" "1"
  }

	// but exclude all symbol files  
	// This can be a full path, or a path relative to ContentRoot
  "FileExclusion" "*.pdb"
}

3、找到sdk\tools\ContentBuilder\content目录在目录下新增文件夹 windows_content

4、复制需要提交的游戏文件至 windows_content 目录下

5、找到sdk\tools\ContentBuilder\目录下的右击编辑 更改内容如下：

builder\steamcmd.exe +loginsteam用户名 密码 +run_app_build_http ..\scripts\app_build_自己的APPID.vdf 

游戏测试无误的时候就双击  等待上传成功了 

暂时先写这么多，后面还会更新 steamwork商店的一些配置
