Unity2D Rotation&Orbit Script

Hi, so I created this script that makes your object orbit other object and rotate. It is centered on transform so u can walk with it and so. Since I couldn't really find solution like this online, i'll post my so you can use it in your project, or improve it. Also, write what you think of it

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. [ExecuteInEditMode]
6. public class Rotations : MonoBehaviour
7. {
8.     [Header("Orbit")]
9.     public bool orbit = true;
10.     public Transform centre;
11.     public float radius;
12.     public float orbitSpeed = 15f;
13.     public float angle;
14.     float radian;
15.  
16.     [Header("Rotate")]
17.     public bool rotate = true;
18.     public bool syncRotations = true;
19.     public bool syncSpeeds = true;
20.     public float rotationSpeed = 15f; // looks the best if is the same as orbitSpeed
21.     public float angleRotation;
22.  
23.     private void Update()
24.     {
25.         if (syncSpeeds) rotationSpeed = orbitSpeed; // Sync Speeds
26.         if (syncRotations && rotate && orbit) angleRotation = angle; // Sync Rotations
27.  
28.         if (Application.isPlaying) // check if script is running in editor mode or in game, if in game rotate object
29.         {
30.             if(orbit)  angle += orbitSpeed * Time.deltaTime;
31.             else if(rotate)  angleRotation += rotationSpeed * Time.deltaTime;
32.         }
33.         checkAngles();
34.  
35.         radian = angle * (Mathf.PI / 180); // convert degrees to radians
36.  
37.         float x = (Mathf.Cos(radian) * radius) + centre.position.x; // calculate x position of orbiting object
38.         float y = (Mathf.Sin(radian) * radius) + centre.position.y; // calculate y position of orbiting object
39.  
40.         transform.position = new Vector2(x, y); // apply new position to orbiting object
41.  
42.         transform.rotation = Quaternion.Euler(transform.rotation.x, transform.rotation.y, angleRotation); // apply new rotation to rotating object
43.     }
44.  
45.     void checkAngles()
46.     {
47.         if (angle >= 360) angle = 0; // keep angle in -360/360 range
48.         else if (angle <= -360) angle = 0;
49.  
50.         if (angleRotation >= 360) angleRotation = 0; // keep angle in -360/360 range
51.         else if (angleRotation <= -360) angleRotation = 0;
52.  
53.     }
54. }
55.  

 

Great thank you ! You can also parent your planet Transform to the star at the correct distance and just vary the Y rotation value of the star if you are really lazy, that's whay I did...
