This is a basic example of a way of handling character selection in Unity.
In order to run this example you'll need to install Zenject. If you don't want to use that then it should be possible to pull the code into MonoBehaviours.
This project uses a basic NavMesh for moving the characters, but you can use whatever you like.
The input controller will run once a frame on Tick and set variables an input state object depending on what buttons the player is clicking.
The ControlsController also runs one a frame but on LateTick, it will use the input state object and has various handlers for the different things it needs to do:
- ControllingHandler: Handles events when the player is not selecting.
- SelectingHandler: Handles events when the player is selecting.
- SelectionDragGuiHandler: Handles drawing the selection box.
- CursorHandler: Handles setting the cursor depending on what's being selected.
The player files have a basic selection handler and movement handler in order to perform selection and movement events.
- MovementHandler: Tells the NavMesh Agent to move to a point or stop.
- SelectionHandler: Sets selecting/selected/deselected on a player.
- PlayerRegistry: This is a utility to give other parts of the system access to existing player characters.
The camera files just contain a handler for raycasting.
- RaycastHandler: Fires a ray at a screen position and returns a RayCastHit.
