Controlling the Player

Checked with version: 5.2

Difficulty: Beginner

In this assignment we'll add a Rigidbody 2D to our player so that they can moved using physics and write a simple C# script to allow us to move the player around the play field.

Code snippet

using UnityEngine;
using System.Collections;

public class CompletePlayerController : MonoBehaviour {

    public float speed;             //Floating point variable to store the player's movement speed.

    private Rigidbody2D rb2d;       //Store a reference to the Rigidbody2D component required to use 2D Physics.

    // Use this for initialization
    void Start()
    {
        //Get and store a reference to the Rigidbody2D component so that we can access it.
        rb2d = GetComponent<Rigidbody2D> ();
    }

    //FixedUpdate is called at a fixed interval and is independent of frame rate. Put physics code here.
    void FixedUpdate()
    {
        //Store the current horizontal input in the float moveHorizontal.
        float moveHorizontal = Input.GetAxis ("Horizontal");

        //Store the current vertical input in the float moveVertical.
        float moveVertical = Input.GetAxis ("Vertical");

        //Use the two store floats to create a new Vector2 variable movement.
        Vector2 movement = new Vector2 (moveHorizontal, moveVertical);

        //Call the AddForce function of our Rigidbody2D rb2d supplying movement multiplied by speed to move our player.
        rb2d.AddForce (movement * speed);
    }
}
