【问题描述】：

我有一个脚本，每次点击都会从头到尾触发一个 linerenderer。我想要一个在释放鼠标按钮之前保持不变的衬里渲染器。就像充电一样。我需要在脚本中添加什么来实现这一点？

using System.Collections;

使用 System.Collections.Generic；使用 UnityEngine；

公共类 RayCastShot : MonoBehaviour {

public float fireRate = 0.25f;
public float weaponRange = 50f;
public float hitForce = 100f;
public Transform gunEndLeft;
public Transform gunEndRight;


private Camera fpsCam;
private WaitForSeconds shotDuration = new WaitForSeconds(0.07f);
private LineRenderer lineRenderer;
private float nextFire;

public Material mat1;
public Material mat2;




void Start()
{
    lineRenderer = GetComponent<LineRenderer>();
    fpsCam = GetComponent<Camera>();


}


void Update()
{

    if (Input.GetButtonDown("Fire1") && Time.time > nextFire)
    {
        nextFire = Time.time + fireRate;

        StartCoroutine(ShotEffect());

        Vector3 rayOrigin = fpsCam.ViewportToWorldPoint(new Vector3(0.5f, 0.5f, 0.0f));

        RaycastHit hit;

        lineRenderer.SetPosition(0, gunEndLeft.position);

        lineRenderer.material = mat1;




        if (Physics.Raycast(rayOrigin, fpsCam.transform.forward, out hit, weaponRange))
        {
            lineRenderer.SetPosition(1, hit.point);

            //get reference to hit point
        }

        if(hit.rigidbody !=null)
        {
            hit.rigidbody.AddForce(-hit.normal * hitForce);
        }

        else
        {
            lineRenderer.SetPosition(1, rayOrigin + (fpsCam.transform.forward * weaponRange));
        }
    }




    if (Input.GetButtonDown("Fire2") && Time.time > nextFire)
    {
        nextFire = Time.time + fireRate;

        StartCoroutine(ShotEffect());

        Vector3 rayOrigin = fpsCam.ViewportToWorldPoint(new Vector3(0.5f, 0.5f, 0.0f));

        RaycastHit hit;

        lineRenderer.SetPosition(0, gunEndRight.position);

        lineRenderer.material = mat2;

        //lineRenderer.material = new Material(Shader.Find("Particles/Priority Additive"));







        if (Physics.Raycast(rayOrigin, fpsCam.transform.forward, out hit, weaponRange))
        {
            lineRenderer.SetPosition(1, hit.point);

            //get reference to hit point
        }

        if (hit.rigidbody != null)
        {
            hit.rigidbody.AddForce(-hit.normal * hitForce);
        }

        else
        {
            lineRenderer.SetPosition(1, rayOrigin + (fpsCam.transform.forward * weaponRange));
        }
    }




}

private IEnumerator ShotEffect()
{
    lineRenderer.enabled = true;

    yield return shotDuration;

    lineRenderer.enabled = false;
}

}

【解决方案1】：

您可以先使用Input.GetButtonUp 来阻止火灾。这样你就可以从Input.GetButtonDown 开始，只有在 buttonUp 时才停止。如果需要每帧执行代码，也可以使用Input.GetButton。

这是基本的想法。
