Mouse Click Movement

Questions & Answers
1

Im trying to use this script to move my character around the map, but am getting no movement, or acknowledgement of the mouse being clicked. Im very confused. Should the mouse buttons be different?

using System.Collections.Generic;
using UnityEngine;

/* Controls the player. Here we choose our "focus" and where to move. */

[RequireComponent(typeof(PlayerMotor))]
public class PlayerController : MonoBehaviour {

	public Interactable focus;	// Our current focus: Item, Enemy etc.

	public LayerMask movementMask;	// Filter out everything not walkable

	Camera cam;			// Reference to our camera
	PlayerMotor motor;	// Reference to our motor

	// Get references
	void Start () {
		cam = Camera.main;
		motor = GetComponent<PlayerMotor>();
	}
	
	// Update is called once per frame
	void Update () {

		// If we press left mouse
		if (Input.GetMouseButton(0))
		{
			// We create a ray
			Ray ray = cam.ScreenPointToRay(Input.mousePosition);
			RaycastHit hit;

			// If the ray hits
			if (Physics.Raycast(ray, out hit, 100, movementMask))
			{
				motor.MoveToPoint(hit.point);   // Move to where we hit
				RemoveFocus();
			}
		}

		// If we press right mouse
		if (Input.GetMouseButton(0))
		{
			// We create a ray
			Ray ray = cam.ScreenPointToRay(Input.mousePosition);
			RaycastHit hit;

			// If the ray hits
			if (Physics.Raycast(ray, out hit, 100))
			{
				Interactable interactable = hit.collider.GetComponent<Interactable>();
				if (interactable != null)
				{
					SetFocus(interactable);
				}
			}
		}
	}

	// Set our focus to a new focus
	void SetFocus (Interactable newFocus)
	{
		// If our focus has changed
		if (newFocus != focus)
		{
			// Defocus the old one
			if (focus != null)
				focus.OnDefocused();

			focus = newFocus;	// Set our new focus
			motor.FollowTarget(newFocus);	// Follow the new focus
		}
		
		newFocus.OnFocused(transform);
	}

	// Remove our current focus
	void RemoveFocus ()
	{
		if (focus != null)
			focus.OnDefocused();

		focus = null;
		motor.StopFollowingTarget();
	}
}```
