Example: unity instantiate prefab in a circle

void InstantiateCircle ()  {     float angle = 360f / (float)pieceCount;     for (int i = 0; i < pieceCount; i++)     {         Quaternion rotation = Quaternion.AngleAxis(i * angle, Vector3.up);         Vector3 direction = rotation * Vector3.forward;          Vector3 position = centerPos + (direction * radius);         Instantiate(prefab, position, rotation);     } }
