我在移动的设备上的Unity游戏中遇到了触摸响应滞后的问题，特别是在发射刀时。在电脑上一切都很顺利，但是，在将游戏传输到手机后，我注意到延迟。
下面是处理刀镜头的代码片段：

using UnityEngine;
public class KnifeScript : MonoBehaviour
{
    
    [SerializeField]
    private Vector2 throwForce;
    //knife shouldn't be controlled by the player when it's inactive 
    //(i.e. it already hit the log / another knife)
    private bool isActive = true;
    //for controlling physics
    private Rigidbody2D rb;
    //the collider attached to Knife
    private PolygonCollider2D knifeCollider;
    private void Awake()
    {
        rb = GetComponent<Rigidbody2D>();
        knifeCollider = GetComponent<PolygonCollider2D>();
    }
    [SerializeField] private AudioSource swist;
    [SerializeField] private AudioSource Gdzwiek;
    void Update()
    {
        //this method of detecting input also works for touch
        if (Input.GetMouseButtonDown(0) && isActive)
        {
            
            rb.AddForce(throwForce, ForceMode2D.Impulse);
            GameController.Instance.GameUI.DecrementDisplayedKnifeCount();
            rb.gravityScale = 1;
            //once the knife isn't stationary, we can apply gravity (it will not automatically fall down)
            
            //Decrement number of available knives
            
            swist.Play();
        }
    }
    [SerializeField] private AudioSource Gloss;
    private void OnCollisionEnter2D(Collision2D collision)
    {
        //we don't even want to detect collisions when the knife isn't active
        if (!isActive)
            return;
        
         
        
         
        //if the knife happens to be active (1st collision), deactivate it
        isActive = false;
        //collision with a log
        if (collision.collider.tag == "Log")
        {
            
            GetComponent<ParticleSystem>().Play();
            Gdzwiek.Play();
            
            
            //stop the knife
            rb.velocity = new Vector2(0, 0);
            //this will automatically inherit rotation of the new parent (log)
            rb.bodyType = RigidbodyType2D.Kinematic;
            transform.SetParent(collision.collider.transform);
            //move the collider away from the blade which is stuck in the log
            knifeCollider.offset = new Vector2(knifeCollider.offset.x, -0.1f);
            
            //Spawn another knife
            GameController.Instance.OnSuccessfulKnifeHit();
        }
        //collision with another knife
        else if (collision.collider.tag == "Knife")
          
        {
            //start rapidly moving downwards
            rb.velocity = new Vector2(rb.velocity.x, -2);
            //Game Over
            GameController.Instance.StartGameOverSequence(false);
            Gloss.Play();
        }
        
    }
}

我使用的是Unity的最新版本，我正在Android手机上进行测试
有谁能帮我找出延迟的原因吗？我是否应该在Rigidbody 2D设置或其他组件中进行调整？
提前感谢您的任何帮助！
