Setting up the input bindings

The first thing that will need to be done is to give the player a way to tell the game which object(s) they want to select. To enable this, the game will need to monitor for input, which will be tied to the left mouse button.

To start, a new Action and Input Binding for the left mouse button will need to be registered within the PlayerInputMapping Input Action asset:

1. Open the PlayerInputMapping Input Actions file.
2. Create a new Action under the Player Action Map and name it Player_Select_Toggle.
3. Set the Binding Input to Left Button [Mouse].
4. Click Save Asset.
