C# （WampSharp）- WAMP

初始化工程

Note.gif

Note: 该示例需要带有对 C# 支持的 Visual Studio 2017 和 NuGet 软件包管理器扩展。

从 WampSharp 1.2.5.36-beta 开始，如果您在 Wwise Authoring 应用的同一台电脑上运行示例，那么您需要将 ws://127.0.0.1:8080 添加为允许的来源（origin）。若要做到这一点，请进入 Project > User Preferences... 并在 Wwise Authoring API 中的 Allowed origins 文本框中添加地址。请注意数值用逗号分隔。

想安装依赖，请在 Visual Studio 2017 中打开示例工程 <Wwise 安装路径>/SDK/samples/WwiseAuthoringAPI/cs/WaapiCS/WaapiCS.sln。通过在解决方案上单击右键并选择 Restore NuGet Packages 来安装依赖。

想选取启动对象，在 Solution Explorer 中右键单击 WaapiCS 工程并点击 Properties。然后选择 Application 选项卡，并在有 Startup object 标签的部分下，选择 WaapiCS.CallWwise。

工程代码

找到示例文件 <Wwise 安装路径>/SDK/samples/WwiseAuthoringAPI/cs/WaapiCS/CallWwise.cs 的位置。

该文件包含以下代码，让您能连接到 Wwise Authoring API。

运行工程

构建解决方案（Ctrl+B）并使用 Visual Studio 运行示例（F5）。

该示例调用两种方法：一种从 Wwise Authoring Application 中获取一般信息，另一种获取在 Application 中选中的对象。

观察输出控制台显示的消息。您应该会看到类似这样的信息：

Calling 'ak.wwise.core.getInfo'
Calling 'ak.wwise.ui.getSelectedObjects'
ak.wwise.core.getInfo: Hello Wwise v2017.1.0
ak.wwise.ui.getSelectedObjects: Got selected object data!
ak.wwise.ui.getSelectedObjects: Got 1 object(s)!
ak.wwise.ui.getSelectedObjects: The first selected object is 'New Sequence Container' ({03E8DC21-EB2F-4607-BFCC-25BCE69DFB27})
ak.wwise.ui.getSelectedObjects: Its parent is 'ParentA' ({FBB64B3C-711C-46E6-9BBC-B49511F08244})
Note.gif

Note: 从 Wwise 中获取的信息，比如对象 ID，会因 Wwise Authoring Application 中打开的工程而异。如果不存在已选项，会显示以下信息：ak.wwise.ui.getSelectedObjects: Select something and try again!
