why should you use 2019.1.0a8 ? can't you at least try with a stable release like Unity 2019.1.14 ?

From the stack trace, it seems like the Agent script is missing from your agent. In 3DBall, this is called Ball 3D Agent. Is this true?

hecong97 commented 4 years ago

The problem is solved with the Unity 2018.4.17. I am new to Unity and don't realize the incompatible between versions
