A simple set of static utilities I'm building up during Unity .

StaticUtils.cs

using UnityEngine;

namespace Streamweaver.Util
{
    public static class StaticUtils
    {
        public static Vector3 GetRandomDir2D()
        {
            return new Vector3(Random.Range(-1f, 1f), Random.Range(-1f, 1f), 0).normalized;
        }

        public static Vector3 GetVectorFromAngle(int angle)
        {
            float angleRad = angle * Mathf.Deg2Rad;
            return new Vector3(Mathf.Cos(angleRad), Mathf.Sin(angleRad));
        }

        public static Vector3 GetVectorFromAngle(float angle)
        {
            float angleRad = angle * Mathf.Deg2Rad;
            return new Vector3(Mathf.Cos(angleRad), Mathf.Sin(angleRad));
        }
    }
}
