Server connected but GetLastFrameOfData() under c++ does not work
Posted: Fri Aug 03, 2018 10:57 pm
Hello,
I am having some trouble using GetLastFrameOfData() in Visual Studio 2017 to get any data from the server. I have two computers, one as server and the other as a client, and I am using NatNet 2.8 x64. I tried the SampleClient.cpp, and "theClient->SetDataCallback( DataHandler, theClient )" works fine and displays the data.
However, when I disabled "theClient->SetDataCallback( DataHandler, theClient )" and tried to receive data by GetLastFrameOfData(). I have added the following codes after it has retrieved Data Descriptions:
But all I received were zeros. The result is displayed as follows:
Does anyone know why? Really appreciate the help!
Best,
Arthur
