,Storing Vector3 arrays in another array?

Questions & Answers
1

I am new to Unity and c# and want to make a freeze effect for a projectile so you can freeze the object, where they would stop moving, and then unfreeze them. Freezing them is easy, as i can just make them kinematic, or just make their velocity 0(Which is what i did, as i turned off gravity) but making then unfreeze is a nightmare. I am trying to store their velocity in a seperate Vector3 array but it just wont work. Help!

public class BulletPause : MonoBehaviour
    {
        Rigidbody rb;
        Vector3[] PreviousSpeed;
        void Start()
        {
            rb = GetComponent<Rigidbody>();    
        }
        void Update()
        {
            if(GameObject.Find("FirstPersonPlayer").GetComponent<PauseBehaviour>().IsPaused == true)
            {
                int[] PreviousSpeed = new Vector3[rb.velocity.GetLength(0)];
                rb.velocity.CopyTo(PreviousSpeed, 0);
                rb.velocity = new Vector3(0, 0, 0);
            }
            if (GameObject.Find("FirstPersonPlayer").GetComponent<PauseBehaviour>().IsPaused != true)
            {
                rb.velocity = PreviousSpeed();
            }
        }
    }

,I am very new to Unity and want to make a simple freeze mechanic for this object, so i can stop them freeze them, and then unfreeze with the same velocity i froze them with. Freezing them is easy, but un freezing is I found challenging, i tried storing their velocity before the freeze in a vector3 array but it wont copy over. Help!

public class BulletPause : MonoBehaviour
{
    Rigidbody rb;
    Vector3[] PreviousSpeed;
    void Start()
    {
        rb = GetComponent<Rigidbody>();    
    }
    void Update()
    {
        if(GameObject.Find("FirstPersonPlayer").GetComponent<PauseBehaviour>().IsPaused == true)
        {
            int[] PreviousSpeed = new Vector3[rb.velocity.GetLength(0)];
            rb.velocity.CopyTo(PreviousSpeed, 0);
            rb.velocity = new Vector3(0, 0, 0);
        }
        if (GameObject.Find("FirstPersonPlayer").GetComponent<PauseBehaviour>().IsPaused != true)
        {
            rb.velocity = PreviousSpeed();
        }
    }
}

Some advice, avoid at all costs using “Find()” in update() its a very expensive Function

you can do it in start()

public GameObject  player;
private PauseBehavior pause;
void Start()
   {
         //you can drop the player in inspector window
        // can also reference it here
                   player=GameObject.Find("FirstPersonPlayer");
                   pause= player.GetComponent<PauseBehavior>();
             
   }

Now, I don’t understand why you want to store your velocity in arrays, I made it storing the previous speed in a local variable, I tried this based in your code

void Update()
	{
			if(pause.Ispaused) //you cand omit ==true  if(true)
				{
					if(!previusSpeedRegistered)  //you must have a boolean for only register the previus speed  only one time
						{
							previusSpeed= rb.velocity;
							previusSpeedRegistered=true;
						}

					rb.velocity= new Vector3(0,0,0);

				}
			else
				{
					rb.velocity=previusSpeed;
				}
	}

Tell me if this works xd
