人工智能的一个小问题。 Unity 中的 Pong 克隆

Question

我在 Pong Clone、C# Unity 中制作 AI 时遇到了一点问题。第一个桨由玩家控制，第二个由 AI 控制。我有以下 AI 脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class AI : MonoBehaviour
 {
   private Rigidbody2D AIrig;
   private GameObject ball;
public float speed = 100;
public float LerpSpeed = 1f;

// Start is called before the first frame update
void Start()
{
   AIrig = GetComponent<Rigidbody2D>();
}



// Update is called once per frame
void FixedUpdate()
{
    ball = GameObject.Find("Ball(Clone)");

    if (ball.transform.position.y > transform.position.y)
    {
        if (ball.transform.position.y < 0)
        {
           
            AIrig.velocity = Vector2.Lerp(AIrig.velocity, Vector2.down * speed, LerpSpeed * Time.deltaTime);
        }

        else
        {
           
            AIrig.velocity = Vector2.Lerp(AIrig.velocity, Vector2.up * speed, LerpSpeed * Time.deltaTime);
        }
    }
    
    if (ball.transform.position.y < transform.position.y && ball.transform.position.x > 1f)
    {
        if (ball.transform.position.y > 0)
        {
           
            AIrig.velocity = Vector2.Lerp(AIrig.velocity, Vector2.up * speed, LerpSpeed * Time.deltaTime);
        }
        else
        {
            
            AIrig.velocity = Vector2.Lerp(AIrig.velocity, Vector2.down * speed, LerpSpeed * Time.deltaTime);
        }
        
    }
    
    
   
}

我不知道如何让 AI 的桨回到它原来的位置。任何人？有什么建议么？我将非常感谢您的任何建议。

首先，不要在您的固定更新方法中找到您的球，因为它很昂贵而且您不需要。而是在开始时找到它，所以基本上将该行移至您的开始功能。

如果您的意思是将原始位置作为起始位置，只需将该位置保持为 vector3 或只是一个浮点数，并且当您希望 AI 移动其原始位置时，只需使用与比较其位置的相同逻辑将其移至该位置或任何其他方式。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class AI : MonoBehaviour
 {
   private Vector3 _originalPosition;// original position for the AI
   private Rigidbody2D AIrig;
   private GameObject ball;
   public float speed = 100;
   public float LerpSpeed = 1f;

// Start is called before the first frame update
void Start()
{
   ball = GameObject.Find("Ball(Clone)"); // finding the ball only 1 time
   AIrig = GetComponent<Rigidbody2D>();
   _originalPosition = AIrig.transform.position; // getting AI's original position
}



// Update is called once per frame
void FixedUpdate()
{
    

    if (ball.transform.position.y > transform.position.y)
    {
        if (ball.transform.position.y < 0)
        {
           
            AIrig.velocity = Vector2.Lerp(AIrig.velocity, Vector2.down * speed, LerpSpeed * Time.deltaTime);
        }

        else
        {
           
            AIrig.velocity = Vector2.Lerp(AIrig.velocity, Vector2.up * speed, LerpSpeed * Time.deltaTime);
        }
    }
    
    if (ball.transform.position.y < transform.position.y && ball.transform.position.x > 1f)
    {
        if (ball.transform.position.y > 0)
        {
           
            AIrig.velocity = Vector2.Lerp(AIrig.velocity, Vector2.up * speed, LerpSpeed * Time.deltaTime);
        }
        else
        {
            
            AIrig.velocity = Vector2.Lerp(AIrig.velocity, Vector2.down * speed, LerpSpeed * Time.deltaTime);
        }
        
    }

    if(canGoToOriginalPosition)// the moment when you want it to go it's original position
    {
        //here you can just do the same logic and lerp it by comparing it's position or any other way.
    }
}
