Question by Kek_Kek · May 21, 2018 at 01:42 AM · linerendererpositioninggrappling gun

Line End Point move with object

I have a grappling type mechanic where if I press a button I create a line. The line works fine on stationary targets but when if there was a moving target the line would hit the target but not move along with it. Is there any way to fix this?

The code:

public Rigidbody player;

 public SteamVR_TrackedObject controller;

 public LineRenderer line;
 private Vector3 target;
 public GameObject Object;
 public float distance;
 bool hitwall = false;
 public float raycastDistance;
 bool pressed = false;
 bool pressed2 = false;
 public Animator anim;
 public GameObject smoke;
 // Update is called once per frame
 void Start()
 {
     smoke.SetActive(false);
 }

 void Update()
 {
     var device = SteamVR_Controller.Input((int)controller.index);
     if (device.GetTouchDown(SteamVR_Controller.ButtonMask.Trigger))
     {
         RaycastHit hit;
         if (Physics.Raycast(controller.transform.position, controller.transform.forward, out hit, raycastDistance))
         {
             line.enabled = true;

             line.SetPosition(0, Object.transform.position);

             target = hit.point;

             line.SetPosition(1, target);



             anim.SetBool("small", true);

             hitwall = true;

             line.material.mainTextureOffset = Vector2.zero;
         }
     }
     else if (device.GetTouch(SteamVR_Controller.ButtonMask.Trigger) && line.enabled)
     {
         line.SetPosition(0, Object.transform.position);

         line.material.mainTextureOffset = new Vector2(line.material.mainTextureOffset.x + Random.Range(-.01f, 0.05f), 0f);

         pressed = true;

         hitwall = true;
     }
     else
     {
         line.enabled = false;
         hitwall = false;
         anim.SetBool("small", false);

     }


     if (device.GetPress(SteamVR_Controller.ButtonMask.Grip) && hitwall == true)
     {
         Debug.Log("Pressed");
         anim.SetBool("big", true);
         player.AddForce((target - controller.transform.position).normalized * 100 * distance);
         smoke.SetActive(true);
     }
     else
     {
         smoke.SetActive(false);
         anim.SetBool("big", false);
     }

 }

}

Line positions should be set every frame if you want it to stay "connected" to 2 different objects. I would add a script to the line renderer game object, inside it make references to 2 transforms (terminal points, you can create empty game objects and place it where you need your terminal points to be as children inside your moving objects), every frame update line positions using these transform references. It is important to use Transform as reference and not Vector3, vectors are just values.
