随机范围的GameObject旋转

Question

I want to do something and I don't even come out. I have a sprite. When I start I want it to be rotated to a random position of these (90f, -180f, -90f). for example give the start, its position is -90f on the z axis, or -180f, or 90f. I am a beginner and I do not know too much. Help!!!

public GameObject sprite;

void Start()
{
    //random z position (90f, -180f, -90f)
    //sprite.transform.Rotate
}

Answer 1

Define an array of the possible rotations, and use Random.Range to pick a random element.

void Start()
{
    Vector3 eulerAngles = sprite.transform.eulerAngles ;
    float[] angles = new float[]{-180f, -90f, 90f};
    int index = Random.Range(0,angles.Length-1);
    eulerAngles.z = angles[index] ;
    sprite.transform.eulerAngles = eulerAngles ;
}
