GameObject rotate

Hey,
I want to create a snake game, but the objects rotate in a way, so they won't be displayed anymore.

The code of the controller is:

Code (CSharp):

1. using UnityEngine;[/I]
2. [I]
3. using System.Collections;
4. using System.Collections.Generic;
5. using System.Linq;
6.  
7.  
8.  
9.  
10. public class Snake : MonoBehaviour
11. {
12.    float timer;
13.    float timelaps = 20;
14.     int direc;
15.    // Did the snake eat something?
16.     bool ate = false;
17.    float x = 0.1F;
18.    float y = 0.1F;
19.    public GameObject GameOver;
20.    // Tail Prefab
21.     public GameObject tailPrefab;
22.     // Head Prefab
23.     public GameObject head;
24.  
25.  
26.     // Current Movement Direction
27.     // (by default it moves to the right)
28.     Vector2 dir = Vector2.down;
29.  
30.     // Use this for initialization
31.     void Start()
32.     {
33.         // Move the Snake every 300ms
34.        //InvokeRepeating("Move",x, y);
35.     }
36.  
37.     // Update is called once per Frame
38.     void Update()
39.     {
40.         // Move in a new Direction?
41.         //head.transform.rotation = Quaternion.AngleAxis(30, Vector3.up);
42.         float step = Time.deltaTime;
43.  
44.         if (Input.GetKey(KeyCode.UpArrow) && dir != Vector2.down)
45.         {
46.             dir = Vector2.up;
47.             head.transform.Rotate(Vector2.up, 90);
48.         }
49.         else if(Input.GetKey(KeyCode.DownArrow) && dir != Vector2.up)
50.         {
51.             dir = Vector2.down;
52.             head.transform.Rotate(Vector2.down, 90);
53.         }
54.         else if (Input.GetKey(KeyCode.RightArrow) && dir != Vector2.left)
55.         {
56.             dir = Vector2.right;
57.             head.transform.Rotate(Vector2.right, 90);
58.             //head.transform.rotation = Quaternion.AngleAxis(30, Vector2.right);
59.         }
60.         else if (Input.GetKey(KeyCode.LeftArrow) && dir != Vector2.right)
61.         {
62.             dir = Vector2.left;
63.             head.transform.Rotate(Vector2.left, 90);
64.             //head.transform.rotation = Quaternion.AngleAxis(30, Vector2.left);
65.         }
66.      
67.        if (timer >= timelaps) {
68.            Move();
69.            timer = 0;
70.        }else{
71.            timer++;
72.        }
73.     }
74. }

Here's a screenshot of the scene:

What rotation method should I use, to rotate the sprite of the game object?

A: The rotated object
B: This is the rotation,
C: This variable needs to be rotated.
​

Please help me to finish the rotation

Best regards

 

Answer 'C'. I'd go with

Code (csharp):

1.  transform.rotation = Quaternion.Euler(0,0,angleVal); // where angleVal is your desired degrees.

I'm most comfortable with that call. Pretty sure angleAxis would work , also.
You can try it on the sprite, just click sort of where the 'z' is in the inspector with your mouse and drag side-to-side and you should see it rotating

 

Hey that's really awesome
Thank you so much.

 

No problem You're welcome.
