testing for successful DLLImport

Unity Engine
1

Hi All,
i’m upgrading our lipsync package for unity. In addition to bulking up the whole product, it supports data from the Lipsync Tool, providing a less expensive, and more portable, option when dealing with pre-recorded audio. The scripts are mostly shared between lipsync data sourced from the microphone (via plugin) or sourced from a text asset (from the lipsync tool).

Everything is kosher except that I have an instance where i’d like to know whether i’ve got the plugin. when the plugin is available, and a case where it’s not. Trying to avoid DllNotFoundException from unity.

LipsyncPlugin is my C# wrapper around native code:
LipsyncPlugin._CloseMicrophone()

I tried to test for null
if (LipsyncPlugin._CloseMicrophone() != null)

Nope. Compile error.

Any tricks or tips?

Thanks and Cheers!

You can try to call the CloseMicrophone function and catch the the DllNotFoundException.
If the exception occurs, then the Dll is not present ; else it is.
