Question

我有一个脚本，每次单击都会从开始位置到结束位置触发一个线性渲染器。我想拥有一个在释放鼠标按钮之前保持不变的划线器。就像充电一样。我需要在脚本中添加些什么才能实现此目的？

using System.Collections;

using System.Collections.Generic; 使用UnityEngine;

        lineRenderer.SetPosition(0, gunEndLeft.position);

        lineRenderer.material = mat1;

        {
            lineRenderer.SetPosition(1, hit.point);

            //get reference to hit point
        }

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




    if (Input.GetButtonDown("Fire2") && Time.time > nextFire)

        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;
}

}

好吧，您可以使用Input.GetButtonUp来阻止火灾。这样，您可以从Input.GetButtonDown开始，仅在buttonUp时停止。如果您需要每帧执行代码，也可以使用Input.GetButton。

这是基本思想。
