First, you have to set up your unique state machine for your simulation. This state machine will determine your vehicle’s flow as they enter the simulation, which possible states and when to exit.
You can duplicate the Parking Animator Controller from Assets > Vehicle Simulation > Animation for reference. Remember to label each state with a unique number to use later on for the Polarith AI module.
Select each transition and make sure the conditions are set correctly. That is Change Equals <Value of Next Unique State Number>
Finally, go to AIController which is located at Assets > Vehicle Simulation > CarparkDriving, to change the Animator Controller to the new State Model you just created.
