8 Dir (Don't Ignore)

If this get ignored then there's a chance that I'll stop using unity for this kind of stuff.

Again I have problems with 8 directional sprites and need help. Here's a script I found and tried to use. Does this look right?

Code (CSharp):

1. using UnityEngine;
2.  
3. public class spriteAngler : MonoBehaviour
4. {
5.     public Transform toFace;
6.     public SpriteRenderer toManipulate;
7.     public Sprite[] mySprites;
8.     private float theta;
9.     private Vector3 a;
10.     void Update()
11.     {
12.         toManipulate.sprite = mySprites[GetAngleIndex()];
13.     }
14.     int GetAngleIndex()
15.     {
16.         a = toFace.position - transform.position;
17.  
18.         a.Normalize();
19.         var b = transform.forward;
20.  
21.         theta = Mathf.Acos(Vector3.Dot(a, b)) * Mathf.Rad2Deg;
22.  
23.         if (a.x * a.z < 0)
24.             theta = 360.0f - theta;
25.  
26.         if (theta >= 292.5f && theta < 337.5f)
27.             return 7;
28.         else if (theta >= 22.5f && theta < 67.5f)
29.             return 1;
30.         else if (theta >= 67.5f && theta < 112.5f)
31.             return 2;
32.         else if (theta >= 112.5f && theta < 157.5f)
33.             return 3;
34.         else if (theta >= 157.5f && theta < 202.5f)
35.             return 4;
36.         else if (theta >= 202.5f && theta < 247.5f)
37.             return 5;
38.         else if (theta >= 247.5f && theta < 292.5f)
39.             return 6;
40.         else if (theta >= 337.5f || theta < 22.5f)
41.             return 0;
42.         else return 0;
43.     }
44.  
45.     private Rect guiPos = new Rect(0, 0, 720, 30);
46.     void OnGUI()
47.     {
48.         GUI.Label(guiPos, "Angle from the Player is: " + theta + " and forward=" + transform.forward + " and vectorToTarget=" + a);
49.     }
50. }
51.  

Help at-least?

 

is there some problem with that script?

 

I ignored, for being vague and none descriptive about potential problem (if any) and silly thread title.

 

Script looks right. Problem description or goodbye, Felicia.

 

I've found a new way but thanks either way.
