Unity3D脚本编写错误汇集

You are trying to create a MonoBehaviour using the 'new' keyword.  This is not allowed. 

using UnityEngine;

namespace Assets
{
    public abstract class AbstractRotaryMovement:MonoBehaviour
    {
        public abstract void Whirling(GameObject gameObject,float x,float y,float z);
    }
}

using System.Threading.Tasks;
using UnityEngine;

namespace Assets
{
    public class ConcreteRotaryMovement3D: AbstractRotaryMovement
    {
        public override void Whirling(GameObject gameObject,float x,float y,float z)
        {
            gameObject.transform.eulerAngles = new Vector3(x, y, z);
        }
        public int Hh()
        {
            return 22;
        }

using UnityEngine;
using System.Configuration;
using System.Reflection;
using System;

public class MoveControl : MonoBehaviour
{
    public ConcreteRotaryMovement3D concreteRotaryMovement3D = new ConcreteRotaryMovement3D();
    public TextClass textClass;
    // Start is called before the first frame update
    void Start()
    {

    }

继承自MonoBehaviour的类，不允许被实例化
