2D Firing an object in the direction the Player is facing!
Hi I am wondering how to get an object to fire in the direction the player is facing. I am currently firing an arrow from a bow object which is attached to the player object in order to maintain movement and to rotate the placeholder sprite with the player.
I have attached my bow script below. I know that my code in the Bow is what is causing the arrow to fire in a straight line but I am unsure on how to make it fire in the same direction the player is facing.
// BOW SCRIPT
public class Bow : MonoBehaviour {
public Rigidbody2D arrow; // Prefab of the arrow.
public float projSpeed = 20f; // The speed of the projectile
public Vector3 Rotation; // Vector 3 to hold rotation
private PlayerMovement playerMove; // Reference to the PlayerControl script.
//private PlayerRotation playerRot; // Reference to the Player Rotation Script
void Awake()
{
// Setting up the references required
// playerMove = transform.root.GetComponent<PlayerMovement>();
}
// Update is called once per frame
void Update ()
{
// Check to see if Fire 1 is pressed
if(Input.GetButtonDown("Fire1"))
{
// Instantiate an arrow!
Rigidbody2D arrowInstance = Instantiate(arrow, transform.position, Quaternion.Euler(new Vector3(0, 0, 0))) as Rigidbody2D;
arrowInstance.velocity = new Vector2(projSpeed, 0);
}
}
}
Thanks in advance.
Assuming the object the script avove is attached to is facing the correct direction to fire the arrow, you can change line 25 to:
arrowInstance.velocity = transform.forward * projSpeed;
Hi,
This has helped shoot it in the direction that the player is facing! Thank you so much!
I ended up copying the players rotation to the bow object (which is attached to the player object) via code. Is there a way to do it so the bow will inherit the direction from the player without the use of code? (sorry for all the questions, I am a unity noob).
Not sure without more info. Typically the spawn point would be a child of the player. Assu$$anonymous$$g the child has a rotation of (0,0,0), then the child's rotation and the parent's rotation will match. But getting the rotation from another game object is perfectly okay.
Using arrowInstance.velocity = transform.up * projSpeed; got this code working properly for me. $$anonymous$$y 2D game has bullets firing out onto the Z plane.
using UnityEngine;
using System.Collections;
public class DanteControllerScript : MonoBehaviour
{
public float maxSpeed = 10f;
bool facingRight = true;
public Rigidbody2D bullet;
Animator anim;
// Use this for initialization
void Start ()
{
anim = GetComponent<Animator> ();
}
// Fixedupdate: do all physic controls here
void FixedUpdate ()
{
float hMove = Input.GetAxis ("Horizontal");
float vMove = Input.GetAxis ("Vertical");
anim.SetFloat ("hSpeed", Mathf.Abs (hMove));
anim.SetFloat ("vSpeed", vMove);
rigidbody2D.velocity = new Vector2 (hMove * maxSpeed, rigidbody2D.velocity.y);
rigidbody2D.velocity = new Vector2 (rigidbody2D.velocity.x, vMove * maxSpeed);
if (hMove > 0 && !facingRight)
Flip ();
else if (hMove < 0 && facingRight)
Flip ();
if (Input.GetButtonDown ("Fire1")) {
Rigidbody2D bulletInstance = Instantiate (bullet, transform.position, Quaternion.Euler(new Vector3(0, 0, 0))) as Rigidbody2D;
bulletInstance.velocity = transform.forward * maxSpeed;
}
}
void Flip()
{
facingRight = !facingRight;
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}
}
I am having the same issue.
Anyone knows what the problem might be? My bullet shoots down all the time instead of the players facing direction.
Thanks
