As mentioned, a Player Controller is a
gameObject that contains the main camera, as well as a simple camera controller. It also contains a script called InworldPlayer for the global chat panel.
The Player Controller is also the
gameObject for communicating with InworldCharacters.
You can click
Add Player Controller to Scene in the Studio Panel to delete the previous
mainCamera in the scene.
If you want to implement your own Player Controller, then drag it to the
InworldPlayer section of the InworldController tab. This is shown below.
