Wwise SDK 2019.2.15

初始化工程

备注: 如果您使用的是 Python 2.7，那么您需要安装 Python 2.7 的 Microsoft Visual C++ Compiler。

从任意目录运行以下命令来安装依赖：

pip install autobahn

如果您使用的是 Python 2.7，请运行以下命令来安装额外的包：

pip install trollius futures

工程代码

备注: 命令行 from waapi_uri import WAAPI_URI 会导入 API 路径声明。

它位于 <Wwise 安装路径>/SDK/include/AK/WwiseAuthoringAPI/py。通过在该示例中扩展 sys.path，该文件的位置被动态添加到 Python 的路径中，但你也可以将 waapi.py 文件通过复制粘贴放到示例文件的相同目录下。

请注意 ak_authobahn.py 这个额外文件提供了一个特殊组件类型，该类型支持将自定义选项发送到 WAAPI。我们在示例目录中提供了该文件。

Python 2.7

找到示例文件 <Wwise installation path>/SDK/samples/WwiseAuthoringAPI/python/low-level/wwise-pubsub-wamp/get_ancestors_py2.py 的位置。

该文件包含以下代码，让您能连接到 Wwise Authoring API。

import sys

import os
 

import trollius as asyncio

from trollius import From
 

from autobahn.asyncio.wamp import ApplicationRunner

from ak_autobahn import AkComponent
 
# You may also copy-paste the waapi.py file alongside this sample
sys.path.append(os.path.join(os.path.dirname(__file__), '../../../../../include/AK/WwiseAuthoringAPI/py'))

from waapi_uri import WAAPI_URI
 
done = False
 

class MyComponent(AkComponent):
    def onJoin(self, details):
        subscription = None
 
        def on_object_created(**kwargs):
            yield From(subscription.unsubscribe())
 
            result = kwargs[u"object"]
 
            print("The object was created in the category: {}".format(result.get(u"category", "unknown")))
 
            arguments = {
                u"from": {u"id": [result.get(u"id")]},
                u"transform": [{u"select": [u"ancestors"]}],
                u"options": {
                    u"return": [u"name"]
                }
            }
 
            res = yield From(self.call(WAAPI_URI.ak_wwise_core_object_get, **arguments))
 
            ancestors = res.kwresults[u"return"]
            print(u"Ancestor of {}:".format(result[u"id"]))
            for ancestor in ancestors:
                print("\t{}".format(ancestor[u"name"]))
            
            global done
            if not done:
                self.leave() # Disconnect
            done = True
            
        subscribe_args = {
            u"options": {
                u"return": [u"id", u"name", u"category"]
            }
        }
 
        # Subscribe to ak.wwise.core.object.created
        # Calls on_object_created whenever the event is received
        subscription = yield From(self.subscribe(on_object_created,
                                  WAAPI_URI.ak_wwise_core_object_created,
                                  **subscribe_args))
 
        print("Create an object in the Project Explorer")
 
    def onDisconnect(self):
        print("The client was disconnected.")
        asyncio.get_event_loop().stop()
 

if __name__ == '__main__':
    runner = ApplicationRunner(url=u"ws://127.0.0.1:8080/waapi", realm=u"get_ancestors_demo")
    try:
        runner.run(MyComponent)
    except Exception as e:
        print(type(e).__name__ + ": Is Wwise running and Wwise Authoring API enabled?")

Python 3.6

找到示例文件 <Wwise installation path>/SDK/samples/WwiseAuthoringAPI/python/low-level/wwise-pubsub-wamp/get_ancestors_py3.py 的位置。

该文件包含以下代码，让您能连接到 Wwise Authoring API。

from ak_autobahn import AkComponent
 
# You may also copy-paste the waapi.py file alongside this sample

            result = kwargs[u"object"]

        subscription = yield from self.subscribe(on_object_created,
                                  WAAPI_URI.ak_wwise_core_object_created,
                                  **subscribe_args)

运行工程

使用以下命令从示例文件的目录中运行该示例文件：

Python 2.7：

python get_ancestors_py2.py

Python 3.6：

python get_ancestors_py3.py

在 Project Explorer 中创建对象，它的祖辈列表就会显示出来。示例会在返回各祖辈对象后终止连接。
