8 Dir (Don't Ignore)

Unity Engine
1

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?

using UnityEngine;

public class spriteAngler : MonoBehaviour
{
    public Transform toFace;
    public SpriteRenderer toManipulate;
    public Sprite[] mySprites;
    private float theta;
    private Vector3 a;
    void Update()
    {
        toManipulate.sprite = mySprites[GetAngleIndex()];
    }
    int GetAngleIndex()
    {
        a = toFace.position - transform.position;

        a.Normalize();
        var b = transform.forward;

        theta = Mathf.Acos(Vector3.Dot(a, b)) * Mathf.Rad2Deg;

        if (a.x * a.z < 0)
            theta = 360.0f - theta;

        if (theta >= 292.5f && theta < 337.5f)
            return 7;
        else if (theta >= 22.5f && theta < 67.5f)
            return 1;
        else if (theta >= 67.5f && theta < 112.5f)
            return 2;
        else if (theta >= 112.5f && theta < 157.5f)
            return 3;
        else if (theta >= 157.5f && theta < 202.5f)
            return 4;
        else if (theta >= 202.5f && theta < 247.5f)
            return 5;
        else if (theta >= 247.5f && theta < 292.5f)
            return 6;
        else if (theta >= 337.5f || theta < 22.5f)
            return 0;
        else return 0;
    }

    private Rect guiPos = new Rect(0, 0, 720, 30);
    void OnGUI()
    {
        GUI.Label(guiPos, "Angle from the Player is: " + theta + " and forward=" + transform.forward + " and vectorToTarget=" + a);
    }
}

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.
