【steam接入】如何将unity游戏接入steam（steamworks）

使用Steamworks.NET，请确保成为steam的开发者（要在steam提交游戏，需要一次性缴纳100美元费用）

Steamwork安装步骤

• 下载 .unitypackage Stable (7.0.0) 或者从 Github 克隆
• 导入下载的所有文件到项目 Assets/ 目录下.
• 打开unity项目，会自动生成steam_appid.txt到项目的主目录下.
• 打开 steam_appid.txt 并将 480 修改为自己的 AppId.
• 编辑\Plugins\Steamworks.NET\types\SteamTypes\AppId_t.cs，将public static readonly AppId_t Invalid = new AppId_t(0x0);将0x0修改为自己的app_id
• 重启unity，保证 steam_appid.txt 已生效.
• 安装sdk完成.

 

如何使用

• 下载SteamManagers.cs
• 将SteamManager.cs脚本挂在GameObject上，steam会自动生成单例
• 完整C#接口请点击查看

接入问题：

 

*使用默认的appid 480可以获取到接口，替换为自己的appid报错steam api初始化失败？

应该是steam帐号里面没有该appid的游戏权限。

*Failed to load 'Assets/Plugins/x86_64/CSteamworks.dll' with error '找不到指定的模块。

还没找到解决办法

*下载报错 Steam安装失败（程序配置文件不可用）或 Failed to start game (invalid app config)

如果测试帐号可以下载安装，而黄色或者红色key不可安装，则是因为应用商店页面清单未完成并提交Valve审核，审核通过才可。具体可以参见steam开发者讨论区 https://steamcommunity.com/groups/steamworks/discussions/0/523897023725510452/

*如何只允许在Steam的某些地区销售？

需要联系Steam客服，说明限制地区和理由 https://partner.steamgames.com/home/contact

*如何测试应用？  

在后台申请红色激活码，使用steam通过激活码进行下载测试。
红色激活码（只能内部使用）、黄色激活码（外部使用）、透明激活码（发布后使用）

*.ico和icns文件如何制作？

使用ico制作软件如IcoFX制作多个尺寸的ico文件，在线做只能输出一个尺寸。需要尺寸16 32 48 64 128 256越多越好。

*Mac发布后，steam安装显示0bytes。

相关程序包与 DLC商店程序包、促销或特殊用途程序包中添加所有depot即可。

*发布mac后打开闪退

发布steam应用mac版本时，确保playersetting下的Mac AppStore Validation取消掉，不然steam版本打开会闪退
