使用C＃脚本在Unity3d中进行2D旋转和碰撞检测

Question

I have a game object, a yellow circle that shown in this picture as my player object and the red one is the child of my player object.

Then If i press spacebar key once, it will rotate by -90 degrees like this

The problem is when i press the spacebar key twice, my player rotating perfectly but it stuck and continue vibrating hitting the pink block.My question is, how can i modify my script to make the player know if it just only can rotate once and prevent the player from rotating again if i press the spacebar key because of the pink block will barrier it rotation.

Here is my Player rotator script.

 public GameObject objToRotate; private bool rotating = false; // Use this for initialization void Start () { } // Update is called once per frame void Update () { if (Input.GetKeyDown (KeyCode.Space)) { StartRotation (); } } private IEnumerator Rotate(Vector3 angles, float duration) { rotating = true; Quaternion startRotation = objToRotate.transform.rotation; Quaternion endRotation = Quaternion.Euler (angles) * startRotation; for (float t = 0; t < duration; t += Time.deltaTime) { objToRotate.transform.rotation = Quaternion.Lerp (startRotation, endRotation, t / duration); yield return null; } objToRotate.transform.rotation = endRotation; rotating = false; } public void StartRotation() { if (!rotating) StartCoroutine (Rotate (new Vector3 (0, 0, -90), 1.1f)); } 

Sorry if i not good in english. Every comments and help are very appreciated.

If you want your coroutine to run just once you can modify it like this

public GameObject objToRotate;
private bool rotating = false;
// Use this for initialization
void Start()
{

}

// Update is called once per frame
void Update()
{
    if (Input.GetKeyDown(KeyCode.Space) && !rotating)
    {
        StartRotation();
    }


}
private IEnumerator Rotate(Vector3 angles, float duration)
{
    rotating = true;
    Quaternion startRotation = objToRotate.transform.rotation;
    Quaternion endRotation = Quaternion.Euler(angles) * startRotation;
    for (float t = 0; t < duration; t += Time.deltaTime)
    {
        objToRotate.transform.rotation = Quaternion.Lerp(startRotation, endRotation, t / duration);
        yield return null;
    }
    objToRotate.transform.rotation = endRotation;

}
public void StartRotation()
{
    if (!rotating)
        StartCoroutine(Rotate(new Vector3(0, 0, -90), 1.1f));
}
