How to change the direction of the bullet?

Question

Game development

Recently started working in Unity. I am doing a simple project. During the development process, the question arose how to change the direction of the bullet? She always flies to the right. I tried many different functions and the result is the same

using UnityEngine;
using System.Collections;
//Код для создания
public class ShootScript : MonoBehaviour
{


    private PlayerControl playerControl;
    public Transform sword;
    

    public float shootingRate = 0.25f;

    public bool isEnemy = true;

    private float shootCooldown;
    private MoveScript move;

    public float fireRate = 0.5f;
    private float nextFire = 1f;
    void Start()
    {
        
        playerControl = GetComponent<PlayerControl>();
       
        move = GetComponent<MoveScript>();
    }

    void Update()
    {
        
        if (nextFire > 1)
        {
            nextFire -= Time.deltaTime;
        }
        
    }
    public void Attack(bool isEnemy)
    {
       
            if (CanAttack && Time.time>nextFire)
            {

            nextFire = Time.time + fireRate;
            var shootTransform = Instantiate(sword) as Transform;


                shootTransform.position = transform.position;


                MoveScript move = shootTransform.gameObject.GetComponent<MoveScript>();
                if (move != null)
                {



                    move.direction = this.transform.right;


                }
            }
        
    }


    public bool CanAttack
    {
        get
        {
            return shootCooldown <= 0f;
            
        }
    }
}

Code for the bullet itself

using UnityEngine;
using System.Collections;

public class MoveScript : MonoBehaviour
{
  public Vector2 speed = new Vector2(80, 80);
  public Vector2 direction = new Vector2(0, 0);
  
  private Vector2 movement;
  private Rigidbody2D rigidbodyComponent;
    private PlayerControl player;
  void Start()
    {
        player = GetComponent<PlayerControl>();
    }
  void Update()
  {
      

           movement = new Vector2(
           speed.x * direction.x * 1,
           speed.y * direction.y * 1);
    }
  void OnCollisionEnter2D(Collision2D  collision) {
    if (collision.transform.tag == "Ground" || collision.transform.tag == "Side") {
      speed = new Vector2(0,0);

    }

  }
   

    void FixedUpdate()
  {
    if (rigidbodyComponent == null) rigidbodyComponent = GetComponent<Rigidbody2D>();
    

    rigidbodyComponent.velocity = movement;
  }
}

Bullet Creation Code

using UnityEngine;
using System.Collections;

public class WeaponControlScript : MonoBehaviour {
    public KeyCode Fire = KeyCode.F;
    private ShootScript shootScript;
    private PlayerControl player;
    // Use this for initialization
    void Start () {
        player = GetComponent<PlayerControl>();
        shootScript = GetComponent<ShootScript>();
    }
  
  // Update is called once per frame
  void Update () {
        
        
            if (Input.GetKeyDown(Fire))
            {
                shootScript.Attack(true);

            }
        
  }
}

If in MoveScript change to

if (player.isFacingRight == true)
        {
            movement = new Vector2(
            speed.x * direction.x * 1,
            speed.y * direction.y * 1);
        } else if  (player.isFacingRight == false)
            {
                movement = new Vector2(
                speed.x * direction.x * -1,
                speed.y * direction.y * 1);
            }

The bullet just falls. I need to make it so that the bullet is in the direction where the cursor was when the fire button was pressed. How to change the direction of the bullet? She always flies to the right.

Answer 1

The bullet flies to the right, because inside the ShootScript it is given this direction:

MoveScript move = shootTransform.gameObject.GetComponent<MoveScript>();
if (move != null)
{
    move.direction = this.transform.right;
}

Ask another - will fly in the other direction. The desired vector can be found using Input.mousePosition and Camera.ScreenToWorldPoint .
In general, especially for such cases, the unit creates tutorial projects , where there are ready-made scripts that you can study and do your own, or use as is.
