Unity车辆选择场景粒子、HP扣减及敌方销毁问题求助

• 选择蓝色车辆时，所有粒子特效异常触发播放
• 撞击敌方车辆后，敌方未按预期触发爆炸特效并被销毁
• 除初始车辆外，其余车辆撞击障碍物（如Crate）时HP扣减逻辑不生效

此前所有功能运行正常，重装电脑后出现以上问题。已自行检查代码并借助ChatGPT排查，未发现代码层面问题；尝试在Start方法中添加private void Start() { Smoke.Stop(); Explosion.Stop();}代码，仍无法解决问题。

相关控制代码如下：

public class PlayerControl : MonoBehaviour
{
private float speed = 20.0f;
private float turnSpeed = 30.0f;
private float horizontalInput;
private bool Won = false;
private bool gameover = false;

    public int Health = 100;
    
    public ParticleSystem Smoke;
    public ParticleSystem Dust;
    public ParticleSystem Dust2;
    public ParticleSystem Explosion;
    
    private void FixedUpdate()
    {
        if (Health <= 50)
        {
            Smoke.Play();
        }
    
        if (SceneManager.GetActiveScene().name == "Car Select")
        {
            return;
        }
        
    }
    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("Target"))
        {
            Won = true;
        }
        if (other.gameObject.CompareTag("Barrier"))
        {
           
            Health -= 3;
            
        }
        else if (other.gameObject.CompareTag("Rock"))
        {
            Health -= 7;
    
        }
        else if (other.gameObject.CompareTag("Crate"))
        {
            Health -= 1;
    
        }
        else if (other.gameObject.CompareTag("Cone"))
        {
            Health -= 4;
    
        }
        else if (other.gameObject.CompareTag("Spool"))
        {
            Health -= 3;
    
        }
        else if (other.gameObject.CompareTag("Barrel"))
        {
            Health -= 2;
    
        }
        else if(other.gameObject.CompareTag("Mega Rock"))
        {
            Health -= 50;
    
        }
        else if (other.gameObject.CompareTag("DeadLine"))
        {
            gameover = true;
            Instantiate(Explosion, transform.position, Quaternion.identity);
            Explosion.Play();
            Destroy(gameObject);
    
        }
        else if (other.gameObject.CompareTag("Enemy"))
        {
            gameover = true;
            Instantiate(Explosion, transform.position, Quaternion.identity);
        }
    }
    // Update is called once per frame
    void Update()
    {
        NoSpeed();
        if (Health <= 0)
        {
            gameover = true;
            speed = 0;
            turnSpeed = 0;
            Health = 0;
        }
        if (Health <= 49)
        {
            speed = 10.0f;
        }
        if (Won == false || gameover == false)
        {
            Explosion.Stop();
    
            horizontalInput = Input.GetAxis("Horizontal");
            //Moves the car forwards
            transform.Translate(Vector3.forward * Time.deltaTime * speed);
            //Rotate the car so it can turn Right or Left to Horizontal Axis
            transform.Rotate(Vector3.up, Time.deltaTime * turnSpeed * horizontalInput);
        }
        if (Health <= 50)
        {
            Smoke.Play();
        }
        if (Health <= 50 || Won == true || gameover == true)
        {
            Dust.Stop();
            Dust2.Stop();
        }
        if(Won == true)
        {
            Won = true;
            speed = 0;
            turnSpeed = 0;
        }
    }
    void NoSpeed()
    {
        if(SceneManager.GetActiveScene().name == "Car Select")
        {
            speed = 0f;
            turnSpeed = 0f;
        }
    }
}
