Small helper script to check angle between 2 objects in degrees (and in between 0-360).
It also includes test code for atan2Approximation, have not measured if there are any benefits using it..
Also note [ExecuteInEditMode], so it runs in editor without playmode.
using UnityEngine;
using System.Collections;
// helper script for testing angle calculation
// USAGE:
// – Attach this script to objectA and assign objectB as target
// – Then select objectA and move it around ObjectB and you can see angle values in inspector
