• 集成SDK后可以支持Steam登录、支付等功能；

TIP

1、需要提前在steam后台 (opens new window)创建应用

2、测试登录需要将测试账号添加到steam后台账户中，具体参考官方文档 (opens new window)

3、只支持Standalong、Development和Debug模式; Shipping模式需要在steam发布后才生效

4、Editor模式UE引擎不支持IOnlineSubsystem，故不支持此模式下调试

1 添加Steam系统插件

1、在UE4编辑器中Settings-Plugins中勾选Online Subsystem、Online Subsystem Steam,如图:

• 勾选后重启UE4编辑器

2、插件项目中Engine-Source-ThirdParty-Steamworks是否包含对应版本SDK文件,如果没有对应SDK文件，则需要下载SteamSDK (opens new window)，并解压后将SDK文件夹拷贝到上述目录中,并修改对应版本信息。

如开发环境:/UE4/UE_4.27/Engine/Source/ThirdParty/Steamworks/Steamv147

• 确保文件目录版本与Steamworks.build.cs中的版本一致

2 DefaultEngine.ini添加设置

1、修改UE4项目工程中Config-DefaultEngine.ini文件，并添加如下Steam相关配置

[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=2307240
bInitServerOnClient=true

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"

[PacketHandlerComponents]
+Components=OnlineSubsystemSteam.SteamAuthComponentModuleInterface

• 其中2307240需要游戏修改为真实申请参数，2307240为官方测试ID，应用id在steam后台 (opens new window)应用详情页面可以看到，如下图官网测试应用：

3 在USDK插件中启用Steam支持

修改 Plugins/HeroUSDKPlugin/Source/HeroUSDKPlugin/HeroUSDKPlugin.Build.cs 文件，添加宏：

#define USE_STEAM

如下图:

4 渠道初始化设置修改

1、游戏游戏开发者在HeroUsdkSupportKit->init方法内部添加isSteamChannel配置.

struct FHeroGameChannelProject gameChannelProject;
//环境参数【请联系成都运营】
gameChannelProject.productId = "D10309A";
gameChannelProject.projectId = "P34345A";
gameChannelProject.serverId = "M1257A";
gameChannelProject.appKey = "VlZdSWMHVjgaxgVfaGl9";
gameChannelProject.appSecret = "YFS3LsBe8sf3UvDiaYqd";
gameChannelProject.gameName = TEXT("PC测试游戏");
gameChannelProject.pkg = "com.hero.pc.sdk";
//支持Steam登录、支付需要开启
gameChannelProject.isSteamChannel = true ;
gameChannelProject.cid = "247";
uProject.gameChannelProject = gameChannelProject;

//PC初始化
HeroUsdkSupportPcDelegate::GetInstance()->Init(uProject);
