tp system problem csharp

Question

hi i'm trying to make my player shot a bullet when "q" is pressed and when he press "q" again he will teleport to the bullet position . Im using this code : (the problem is on the update function )

public class RobotController : MonoBehaviour { public float nextFire; public float fireRate; public bool tp= false ; public GameObject projectile; public Transform spawn; public float maxSpeed = 10f ; bool facingRight = true; public float lifeTime = 3f; public Transform proj; Animator anim ; // Use this for initialization void Start () {

     anim = GetComponent<Animator>();
 }
 
 // Update is called once per frame
 void FixedUpdate () {
 
     float move = Input.GetAxis ("Horizontal");

     anim.SetFloat ("speed", Mathf.Abs (move));
     rigidbody2D.velocity = new Vector3 (move * maxSpeed, rigidbody2D.velocity.y,0);

     if (move < 0 && facingRight)
         Flip ();
     else if (move > 0 && !facingRight)
         Flip ();

 }

 void Update(){

     if (Input.GetKey ("mo") && tp == false && Time.time > nextFire ) {

         Spawn ();
         nextFire = Time.time + fireRate;
         tp = true;

     
     }

     if (Input.GetKey ("q") && tp == true) {

         gameObject.transform.position = new Vector2 ( proj.transform.position.x,proj.transform.position.y);
     
         tp = false;

     }

 }
 void Flip (){

     facingRight = !facingRight;

     Vector3 theScale = transform.localScale;

     theScale.x *= -1;

     transform.localScale = theScale;



 }

 void Spawn (){
     GameObject clone;
     clone =  (GameObject) Instantiate (projectile, spawn.position, spawn.rotation);
     Destroy (clone, lifeTime);

     projectile = clone;
 }

}

projectile is the prefab of my bullet , the transform proj = projecile . the problem that instead of tp on the bullet the player tp on the first position of the projectile setted in the prefab wats wrong ?

You asign the position of the bullet to projectile, but teleport the player to proj, wich was never asigned in your code? Rename projectile to proj at:

projectile = clone

proj is a transform I can't make proj = clone cause clone is a GameObject and in unity a asign the transform proj = projectile

just get the Transform component from your GameObject. It will keep it self updated with the origin Gameobject cause ist just a Referenz

 clone.tranformation

Answer 2

it still didn't work . But I changed the script and it worked here the code if you want to know and thanks for the help ^^

public float nextFire; public float fireRate;

 public float nextTp;
 public float tpRate;
 public GameObject projectile;
 public Transform spawn;
 public float maxSpeed = 10f ; 
      bool facingRight = true;
 public float lifeTime = 3f;
 GameObject tmp;

 float projInstanceMouseX;
 float projInstanceMouseY;

 Animator anim ;
 // Use this for initialization
 void Start () {
 
     anim = GetComponent<Animator>();
 }
 
 // Update is called once per frame
 void FixedUpdate () {
 
     float move = Input.GetAxis ("Horizontal");

     anim.SetFloat ("speed", Mathf.Abs (move));
     rigidbody2D.velocity = new Vector3 (move * maxSpeed, rigidbody2D.velocity.y,0);

     if (move < 0 && facingRight)
         Flip ();
     else if (move > 0 && !facingRight)
         Flip ();

 }

 void Update(){    

     if ((Input.GetKey ("q")) && (tmp == null) && (Time.time > nextFire || Time.time < 2f)) {
         Debug.Log("instanciate");
         nextTp = Time.time + tpRate;
         Spawn ();
         nextFire = Time.time + fireRate;
     } else if ((Input.GetKey ("q")) && (Time.time > nextFire && Time.time > nextTp ) && (tmp != null)) {


         gameObject.transform.position = new Vector2 (tmp.transform.position.x, tmp.transform.position.y);
         Destroy(tmp);
         nextFire = Time.time + fireRate;
         Debug.Log("destroy");
     } else if (tmp != null) {
         tmp.rigidbody2D.velocity = new Vector2 (projInstanceMouseX * Time.deltaTime * maxSpeed, projInstanceMouseY * Time.deltaTime * maxSpeed);
     }


 }
 void Flip (){

     facingRight = !facingRight;

     Vector3 theScale = transform.localScale;

     theScale.x *= -1;

     transform.localScale = theScale;



 }

 void Spawn (){
     projInstanceMouseX = Input.mousePosition.x;
     projInstanceMouseY = Input.mousePosition.y;
     
     tmp = (GameObject)Instantiate (projectile, spawn.position, spawn.rotation);
     Destroy (tmp, lifeTime);
 }

}
