Now that we have our demonstration recording, we can do more on the training part. This time, however, we will play back our observation file to multiple agents in multiple environments. Open the Hallway/VisualHallway sample scene and follow the next exercise to set up for training:

1. Select and enable all the HallwayArea training environments HallwayArea(1) to HallwayArea(15)
2. Select HallwayArea | Agent in the Hierarchy and then switch Hallway Agent | Brain to HallwayLearning, as shown in the following screenshot:

3. Also, select and disable the Demonstration Recording component as shown in the preceding screen excerpt
4. Make sure all the agents in the scene are using HallwayLearning brains

5. Select Academy in the Hierarchy and then enable the Hallway Academy | Brains | Control option as shown in the following screenshot:

6. Save the scene and project

Now that we have the scene configured for agent learning, we can move on to feeding the agent in the next section.
