在 Unity 中使对象沿随机方向移动

Question

I have an EnemyTest gameobject that, through an EnemyDmg script, instantiates a damage number whenever a weapon hits it. I would like to put a script on the damage number prefab that will make it move in a random direction in 2-dimensional space. I know other people have asked this, but the thing is, I would like to be able to move the damage number without rotating it, so that it can still be easily read. I am planning on putting the code for the damage number movement in a new script on the prefab, contained within a void Awake() method.

This is the EnemyDmg script:

public class EnemyDmg : MonoBehaviour
{
    GameObject EnemyCanvas;
    public GameObject DmgNmbr;

    void Start()
    {
        EnemyCanvas = this.gameObject.transform.GetChild(0).gameObject;
    }

    void OnCollisionEnter2D(Collision2D Collider)
    {
        if (Collider.gameObject.tag == "Weapon")
        {
            Debug.Log("Enemy Hit!");
            Instantiate(DmgNmbr, EnemyCanvas.transform);
        }
    }
}

As it currently is, this is what happens when a weapon hits the enemy: Google Drive Video . I would like the yellow number to fly off of the enemy in a random direction, although it doesn't have to go very far. From this perspective, the x-axis is left and right, and the y-axis is up and down.

In that link someone has given a recipe for moving an object in a random direction. However, I could not understand what exactly you do ask.

private Vector3 RandomVector(float min, float max) {
     var x = Random.Range(min, max);
     var y = Random.Range(min, max);
     var z = Random.Range(min, max);
     return new Vector3(x, y, z);
 }

 void Start()
 { 
     var rb = GetComponent<Rigidbody>();
     rb.velocity = RandomVector(0f, 5f);
 }
