Vehicle sinking into the floor #2

Closed syedjawadakhtar closed 4 years ago

syedjawadakhtar commented 4 years ago

Pressing the play button, the vehicle sinks into the floor and the console starts throwing errors every passing second.

Same Error:

UnassignedReferenceException: The variable target of AUV_Agent has not been assigned.
You probably need to assign the target variable of the AUV_Agent script in the inspector.

The latest update to Unity and ml-agents fixed all issues. The vehicle is running according to the trained model.
