CustomTopDownController.cs

A component that overrides player control for a top-down style. It reads input to set the PlayerController's desired velocity and smoothly rotates the view toward movement direction, and it positions the scene camera above and behind the player at a fixed angle.

public sealed class CustomTopDownController : Component
{
	[RequireComponent] PlayerController Controller { get; set; }

	protected override void OnFixedUpdate()
	{
		// Lets make the player move when we press WASD
		var speed = Input.Down( "Run" ) ? Controller.RunSpeed : Controller.WalkSpeed;
		Controller.WishVelocity = Input.AnalogMove * speed;

		// And rotate the player to face the direction of the movement
		if ( Controller.WishVelocity.LengthSquared > 0 )
		{
			var targetAngle = Controller.WishVelocity.EulerAngles;
			Controller.EyeAngles = Rotation.Slerp( Controller.EyeAngles, targetAngle, Time.Delta * 10f );
		}
	}

	protected override void OnPreRender()
	{
		// This will update the camera's position so that it's up in the air and back a bit, looking down at an angle.
		Scene.Camera.WorldPosition = Controller.WorldPosition + Vector3.Up * 1024f + Vector3.Backward * 256f;
		Scene.Camera.WorldRotation = new Angles( 75, 0, 0 );
	}
