Error when writing parameter in the bank for the Low pass filter demo plugin

Question

Hi,
I've been following the example here for a low pass filter plugin (https://www.audiokinetic.com/en/library/edge/?source=SDK&id=code_effectplugin_runthrough.html) and I hit an error for the line that updates the frequency parameter in the bank - 

// Write bank data here

in_pDataWriter->WriteReal32(m_propertySet.GetReal32(in_guidPlatform, "Frequency"));

error C2039: 'GetReal32': is not a member of 'AK::Wwise::IPluginPropertySet' [C:\Users\Anantha\Documents\Wwise_plugins\MyFilter\WwisePlugin\MyFilter_Authoring_Windows_vc160.vcxproj]

Looks like the function is not a part of the IPluginPropertySet class? Do I need to inherit from another class or has this function been removed?

Any advice woould be appreciated.

thanks

This tutorial expects you to use the newer Authoring API first introduced in 21.1. This API is found under the AK::Wwise::Plugin:: namespace (see files under "Wwise <version>/SDK/include/AK/Wwise/Plugin").

The legacy, pre-21.1 plug-in API has classes under AK::Wwise:: and has been preserved for backward compatibility, however it is deprecated and should not be used for new plug-ins.

In the tutorial, the template plug-in generated by "wp.py new" already uses the new API; the class inherited by the Authoring plug-in is AK::Wwise::Plugin::AudioPlugin instead AK::Wwise::DefaultAudioPluginImplementation.
The type of m_propertySet, in this case, is AK::Wwise::Plugin::PropertySet (as requested automatically by AK::Wwise::Plugin::AudioPlugin) and does provide the GetReal32 function.

Oh my bad - I was on an older Wwise SDK, thanks a lot Samuel!
