Hello ViolinRobot,
The OtherCompliationError message always means that you can get more information on what actually happened in the Output log. It’s just a generic error message for when there isn’t an error message for that particular problem.
As for the issue you’re running into now, this is most likely not an issue with the Actor class but something that you may of set up incorrectly. Could you provide the code for where this error is occurring?
