Question by Zeradias · May 30, 2017 at 05:32 PM · 2drotationrigidbody2dvelocityprojectile

Projetil rotation in straight line trajectory

Good evening, I would like a help in a script, with a 2D game TopDown, I wish the enemies could throw arrows, straight line, but fowards the player, however, I could not make the arrow sprite spin on its axis Without affecting the straight trajectory. Tips to incorporate?

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Blast : MonoBehaviour {

 public float speed;
 public GameObject player;
 private Rigidbody2D myRigidbody;
 private Animator anim;
 public Vector3 vDirection;
 public float angle;
 // Use this for initialization
 void Start () {
     myRigidbody = GetComponent<Rigidbody2D>();
     anim = GetComponent<Animator>();
     vDirection = player.transform.position - gameObject.transform.position;
     vDirection = vDirection.normalized;
 }

 void Update () {
     player = BlasterAttack.PlayerT;
     myRigidbody.velocity = transform.TransformDirection (vDirection * speed);

}

Set sprite as a child of arrow Game Object. Move that Game Object and spine the child.

If you are translating and rotating the same object, then its trajectory will change.

1) Make a parent of the arrow. Do all the translations to this guy.

2) Now the arrow will follow the translation of its parent. Now perform all your rotations to this guy.
