[Redacted] Make a script accessible like Mathf?

I would like to access this scripts ShootPrediction function similar to how you would any Mathf function but am not completely sure how to do so.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class SS_Shoot_Predict : MonoBehaviour {
5.  
6.     Vector3 ShotPrediction (Transform position, Transform target, Rigidbody bullet)
7.     {
8.         Vector3 relativeTargetposition = position.position + (target.position - transform.position);
9.         Vector3 relativeTargetVelocity = target.GetComponent<Rigidbody> ().velocity;
10.         float speed = bullet.GetComponent<SS_Bullet> ().speed;
11.  
12.         float t = TimeToImpact (relativeTargetposition, relativeTargetVelocity, speed);
13.         return relativeTargetposition + relativeTargetVelocity * t;
14.     }
15.  
16.     float TimeToImpact (Vector3 position, Vector3 relativeTargetVelocity, float bulletSpeed)
17.     {
18.         float a = bulletSpeed * bulletSpeed - (Vector3.SqrMagnitude (relativeTargetVelocity));
19.         float b = Vector3.Dot (position, relativeTargetVelocity);
20.         float c = Vector3.SqrMagnitude (position);
21.  
22.         float d = b * b + a * c;
23.         float t = 0;
24.  
25.         if (d >= 0)
26.         {
27.             t = (b + Mathf.Sqrt (d)) / a;
28.             if (t < 0)
29.                 t = 0;
30.         }
31.  
32.         return t;
33.     }
34. }

 

Make it a static class. Make all of its members static.

This approach is ideal for a stateless helper class, like Mathf.
