I have a script which fires a linerenderer from a start to end position with each click. I want to have a linerender that is constant until the mouse button is released. Like a power charge. What do I need to add in the script to make this happen?

Well you can start by use Input.GetButtonUp to stop the fire.
That way you can start on Input.GetButtonDown and stop only when buttonUp.
If you need to execute code every frame you can also use Input.GetButton.
That's the basic idea.

Here's the issue:
I have a raycast reflection that reflects normally, but when it encounters a straight wall it reflects in the X-Z plane.
I have it running (Code provided at the end of this explanation)
It looks like this:
Reflection Angle#01
Another: Reflection Angle#02
My main issue is making the bullets bounce according to my special laws of reflection, here's what I've been able to achieve by taking some help from code online:
Out of sync bullet.gif
As you can tell, the bullet is a bit skewed, I imagined it's because of the collision calculations since I turned off gravity and just use rigidbody.velocity to shoot these bullets, here's the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
namespace StarterAssets
{
using UnityEngine;
public class CollisionDetector : MonoBehaviour
{
[SerializeField]
[Tooltip("Just for debugging, adds some velocity during OnEnable")]
private Vector3 initialVelocity;
[SerializeField]
private float minVelocity = 3f;
private Vector3 lastFrameVelocity;
private Rigidbody rb;
private void OnEnable()
{
transform.localScale = new Vector3(.5f, .5f, .5f);
rb = GetComponent<Rigidbody>();
rb.velocity = transform.forward * minVelocity;
}
private void Update()
{
lastFrameVelocity = rb.velocity;
}
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.CompareTag("Mirror"))
{
Bounce(collision.contacts[0].normal);
}
Physics.IgnoreCollision(collision.collider, GetComponent<Collider>());
}
private void Bounce(Vector3 collisionNormal)
{
rb.velocity = lastFrameVelocity;
var speed = lastFrameVelocity.magnitude;
Vector3 direction;
if (Mathf.Abs(collisionNormal.y) < .5)
{
var previousDirection = lastFrameVelocity.normalized;
previousDirection.y = 0;
var xzNormal = collisionNormal;
xzNormal.y = 0;
direction = Vector3.Reflect(previousDirection, xzNormal);
}
else
direction = Vector3.Reflect(lastFrameVelocity.normalized, collisionNormal);
Debug.Log("Out Direction: " + direction);
//rb.AddForce(direction * Mathf.Max(speed, minVelocity));
rb.velocity = direction * minVelocity;
}
}
}
Here's the code for the laser reflections:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[RequireComponent(typeof(LineRenderer))]
public class RaycastReflection : MonoBehaviour
{
public int reflections;
public float maxLength;

// Start is called before the first frame update

{

}
// Update is called once per frame
void Update()
{
ray = new Ray(transform.position, transform.forward);
//lineRenderer.material.color = Color.cyan;
lineRenderer.positionCount = 1;
lineRenderer.SetPosition(0, transform.position);
float remainingLength = maxLength;
for (int i = 0; i < reflections; i++)
{
if (Physics.Raycast(ray.origin, ray.direction, out hit, remainingLength,~(1 << 2)))
{
lineRenderer.positionCount += 1;
lineRenderer.SetPosition(lineRenderer.positionCount - 1, hit.point);
remainingLength -= Vector3.Distance(ray.origin, hit.point);
if(Mathf.Abs(hit.normal.y) <.5)
{
var previousDirection = ray.direction;
previousDirection.y = 0;
var xzNormal = hit.normal;
xzNormal.y = 0;
//var direction = Vector3.Reflect(previousDirection, xzNormal);
ray = new Ray(hit.point, Vector3.Reflect(previousDirection, xzNormal));
}
else
{
ray = new Ray(hit.point, Vector3.Reflect(ray.direction, hit.normal));
}
if (hit.collider.tag == "Totem")
{
//lineRenderer.material.color = new Color(0.4f, 0.9f, 0.7f, 1.0f);
break;
}
if (hit.collider.tag != "Mirror")
{
break;
}
}
else
{
lineRenderer.positionCount += 1;
lineRenderer.SetPosition(lineRenderer.positionCount - 1, ray.origin + ray.direction * remainingLength);
}
}
}
}
One of the easiest solutions I could think was to make the sphere/box collider extremely small, the collisions wouldnt cause a massive issue, and at slow speeds, this is true, it functions almost exactly like it's supposed to, but at higher speeds it's completely off the path again.
Another solution was to calculate the ray again from the cube, get the value of the hit.point reflections and put that inside the direction variable, use that to change my velocity each time,
Sadly doesn't work that conveniently
Here's my attempt:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
namespace StarterAssets
{
using UnityEngine;
public class CollisionDetector : MonoBehaviour
{
[SerializeField]

private void OnEnable()
{
ray = new Ray(transform.parent.parent.position, transform.parent.parent.forward);
Physics.Raycast(ray.origin, ray.direction, out hit, 20000, ~(1 << 2));
transform.localScale = new Vector3(.15f, .15f, .15f);
rb = GetComponent<Rigidbody>();
// rb.AddForce(ray.direction * minVelocity, ForceMode.Impulse);
rb.velocity = ray.direction * minVelocity;
}
private void Update()
{
lastFrameVelocity = rb.velocity;
}
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.CompareTag("Mirror"))
{
Bounce(collision.contacts[0].normal);
}
else
Physics.IgnoreCollision(collision.collider, GetComponent<Collider>());
}
private void Bounce(Vector3 collisionNormal)
{
//var speed = lastFrameVelocity.magnitude;
Vector3 direction;
// transform.SetPositionAndRotation(hit.point, lastRotation);
transform.position = hit.point;
if (Mathf.Abs(hit.normal.y) < .5)
{
//var previousDirection = lastFrameVelocity.normalized;
//previousDirection.y = 0;
//var xzNormal = collisionNormal;
//xzNormal.y = 0;
//direction = Vector3.Reflect(previousDirection, xzNormal);
var previousDirection = ray.direction;
previousDirection.y = 0;
var xzNormal = hit.normal;
xzNormal.y = 0;
direction = Vector3.Reflect(previousDirection, xzNormal);
ray = new Ray(hit.point, direction);
}
else {
//direction = Vector3.Reflect(lastFrameVelocity.normalized, collisionNormal);
direction = Vector3.Reflect(ray.direction, hit.normal);
ray = new Ray(hit.point, direction);
}
Physics.Raycast(ray.origin, ray.direction, out hit, 20000, ~(1 << 2));
Debug.Log("Out Direction: " + direction);
//rb.AddForce(direction * Mathf.Max(speed, minVelocity));
//rb.velocity = direction * Mathf.Max(speed, minVelocity);
//rb.AddForce(direction * minVelocity, ForceMode.Impulse);
rb.velocity = direction * minVelocity;
}
}
I've also tried Vector3.MoveTowards and .Lerp, but I wasn't able to do it properly.
Please help! I have no idea how to make this darn bullet follow the laser path.
I have object that move around in fixed radius around another object with random height.
In this script i want the transform(turret) to rotate facing the target(target is the object that move with the random height) and that the laser that shoot will hit all the time the moving around target.
In the original i used the mouse to rotate the transform to be facing objects but now i want that the transform will rotate automatic to the moving target with the laser.
I added this part to the script and the laser start when running the game but the transform is not rotating facing the target. and i still can rotate the transform with the mouse and in this case i don't want the mouse to rotate the transform but that the transform will be rotating automatic.
if (startLaser)
{
Destroy(Instance);
Instance = Instantiate(Prefabs[Prefab], FirePoint.transform.position, FirePoint.transform.rotation);
Instance.transform.parent = transform;
LaserScript = Instance.GetComponent<Hovl_Laser>();
LaserScript2 = Instance.GetComponent<Hovl_Laser2>();
startLaser = false;
}
if (Cam != null)
{
RaycastHit hit;
RayMouse = Cam.ScreenPointToRay(target.position);
if(Physics.Raycast(RayMouse.origin, RayMouse.direction, out hit, MaxLength))
{
RotateToMouseDirection(gameObject, hit.point);
}
else
{
var pos = RayMouse.GetPoint(MaxLength);
RotateToMouseDirection(gameObject, pos);
}
}
but it's not working the transform is not rotating automatic and the mouse still controlling the rotating.

I am integrating my game to VR and now i wanted to change my controlling. In the script given bellow when the player press the mouse button the gun fires the bullet but now in VR i don't want my game to be controlled by any controller. what i want is when player moves his head and the focus point comes to the Enemy it starts shooting without pressing any button(I mean auto shoot). what should i do??

Since you already have an existing shooting mechanic, simply changing up the Update() should do what you want
void Update () {
if (Time.time >= nextTimeToFire)
{
nextTimeToFire = Time.time + 1f / fireRate;
Shoot();
}

I made an AI Enemy system that has the enemy walk towards a target that I want to attack.The target (who is the player collects points). What I want is when the enemy reaches its target it takes away -1 point from the player. What I want to know is how do I deduct the point from my game manager. I already created a public game object that carries the script for my points. When I try this out the enemy does not take a point away once it reaches the player. Should I create a function within my Enemy AI script called TargetIsReached()?

//RaycastHit hit;
if (Physics.Raycast(ray, out hit, touchInputMask)){
GameObject recipient = hit.transform.gameObject;
touchList.Add(recipient);
if (touch.phase == TouchPhase.Began){
recipient.SendMessage("OnTouchDown",hit.point,SendMessageOptions.DontRequireReceiver);
}
if (touch.phase == TouchPhase.Ended){
recipient.SendMessage("OnTouchUp",hit.point,SendMessageOptions.DontRequireReceiver);
}
if (touch.phase == TouchPhase.Stationary || touch.phase == TouchPhase.Moved){
recipient.SendMessage("OnTouchStay",hit.point,SendMessageOptions.DontRequireReceiver);
}
if (touch.phase == TouchPhase.Canceled){
recipient.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver);
}
}
}
foreach (GameObject g in touchesOld){
if (!touchList.Contains(g)){
g.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver);
}
}
}
}
}
Now finally perform this process, i could perform this process in two ways
Using touchScript library, it has a rich feature we can drag, rotate, translate and scale multiple object in one time.

Note: this is older video, now it changes but it is almost same.
[TouchScript is available in asset store for free]
other option, attach below code in empty gameobject or in camera(add tag layer)
