Question by isavage0 · Nov 16, 2016 at 07:42 PM · projectile

How can I make my projectile move in a sine pattern (2d plat)?

I initially had a projectile that moved directly out, but I want a sine pattern now. I found a code for a space shooter and it kind of works, but having issues getting it to go both directions now >< I feel pretty dumb now.

In my projectile:

 [SerializeField]
 private float speed = 5.0f;

 private Rigidbody2D body2d;
 private Vector3 direction;
 public int damage;

 public float frequency = 20.0f;
 public float magnitude = 0.5f;
 private Vector3 axis;
 private Vector3 pos;

 void Start()
 {
     pos = transform.position;
     DestroyObject(gameObject, 1.0f);
     axis = transform.up; 
 }

 void FixedUpdate()
 {
     pos += transform.right * Time.deltaTime * speed;
     transform.position = pos + axis * Mathf.Sin(Time.time * frequency) * magnitude;
 }

 public void Initialize(Vector3 direction)
 {
     this.direction = direction;
 }

 public void OnTriggerEnter2D(Collider2D other)
 {
     if (other.tag == "Enemy")
     {
         other.GetComponent<batsController>().TakeDamage(damage);
         //Destroy(gameObject);
     }
 }

 void OnBecameInvisible()
 {
     Destroy(gameObject);
 }

In my character abstract class:

 protected Animator myAnimator;

 [SerializeField]
 public Transform heartPos;

 [SerializeField]
 protected float movementSpeed;

 protected bool facingRight;

 [SerializeField]
 private GameObject heartPrefab;

 public bool Attack { get; set; }

 // Use this for initialization
 public virtual void Start()
 {
     facingRight = true;
     myAnimator = GetComponent<Animator>();
 }

 // Update is called once per frame
 void Update()
 {

 }

 public void ChangeDirection()
 {
     facingRight = !facingRight;
     transform.localScale = new Vector3(transform.localScale.x * -1, 2, 2);
 }

 public virtual void ThrowHeart(int value)
 {
     if (facingRight)
     {
         GameObject tmp = (GameObject)Instantiate(heartPrefab, heartPos.position, Quaternion.identity);
         tmp.GetComponent<heartController>().Initialize(Vector3.right);
     }
     else
     {
         GameObject tmp = (GameObject)Instantiate(heartPrefab, heartPos.position, Quaternion.identity);
         tmp.GetComponent<heartController>().Initialize(Vector3.left);
     }
 }

}

@isavage0 it's been long time you add this question, but i found a tutorial that might help people to implement trajectory projectile in their games.
