Setting Line Render position directly forward from facing of game object

Questions & Answers
1

So I have this script here that handles the firing of a weapon using raycasts and I’m trying to have it use a Line Renderer directly forward from the facing of the gun object. Initially I used hitInfo.point as the 2nd point for the line renderer but as there is no collision with the sky the line will not render there. After reading through other answers I determined that transform.TransformDirection(Vector3.forward) should project the line forward but when I run my game the line is always rendered to a fixed point despite which direction my player is facing ( and hence the gun’s facing direction). If anyone could point out my mistake here, it would be much appreciated.

    public class RaycastMachineGun : MonoBehaviour {
	
	float mCooldown = -0.1f;
	float mFireRate = 0.1f;
	
	int mGunAmmo = 0;
	int mGunMaxAmmo = 500;

	int mGunDamage = 10;
	
	LineRenderer mGun;
	float mGunCountDown = 0.125f;
	float mCurrentCountDown = 0.0f;
	
	void Start () {
		mGun = GetComponent<LineRenderer>();
		mGun.enabled = false;
		mGun.SetVertexCount (2);
		mGun.SetWidth (0.01f, 0.01f);
		mGun.SetColors (Color.yellow, Color.yellow);
		mGunAmmo = mGunMaxAmmo;
	}
	
	void Update () {
		if(Input.GetButton("Fire1") && Time.time > mCooldown && mGunAmmo > 0)
		{
			mGunAmmo--;
			RaycastHit hitInfo;
			Vector3 direction = transform.TransformDirection(Vector3.forward);

			if (Physics.Raycast(transform.position, direction, out hitInfo))
			{
				if(hitInfo.transform.tag != "Player")
				{
					Health enemyHealth = hitInfo.transform.GetComponent<Health>();
					if (enemyHealth!= null)
					{
						enemyHealth.mDamage(mGunDamage);
					}
				}
				mGun.enabled = true;
				mGun.SetPosition(0, transform.position);
				mGun.SetPosition(1, direction);
			}
			mCooldown = Time.time + mFireRate;
		}
		
		mCurrentCountDown += Time.deltaTime;
		if (mCurrentCountDown >= mGunCountDown)
		{
			mGun.enabled = false;
			mCurrentCountDown = 0.0f;
		}
	}

	void OnGUI(){
		GUI.Label (new Rect (5, Screen.height - 45, 100, 100), "Ammo: " + mGunAmmo.ToString () + " / " + mGunMaxAmmo.ToString ());
	}
}

Also as this is my first question on here, I’m not entirely sure I formatted everything properly, if someone could also point me to where to do that, thanks in advance.

I have since managed to fix my own mistake using the following code

public class RaycastMachineGun : MonoBehaviour {
	
	float mCooldown = -0.1f;
	float mFireRate = 0.1f;
	
	int mGunAmmo = 0;
	int mGunMaxAmmo = 500;

	float mGunDamage = 10.0f;
	
	LineRenderer mGun;
	float mGunCountDown = 0.125f;
	float mCurrentCountDown = 0.0f;
	
	void Start () {
		//Set values for line renderer as feedback
		mGun = GetComponent<LineRenderer>();
		mGun.enabled = false;
		mGun.SetVertexCount (2);
		mGun.SetWidth (0.01f, 0.01f);
		mGun.SetColors (Color.yellow, Color.yellow);

		//Intially set the amount of ammo to max
		mGunAmmo = mGunMaxAmmo;
	}
	
	void Update () {
		//Check if player fires
		if(Input.GetButton("Fire1") && Time.time > mCooldown && mGunAmmo > 0)
		{
			//Subtract from ammo
			mGunAmmo--;

			RaycastHit hitInfo;
			Vector3 direction = transform.TransformDirection(0,0,1);

			//Find the object that is hit
			if (Physics.Raycast(transform.position, direction, out hitInfo))
			{
				if(hitInfo.transform.tag != "Player")
				{
					//Render the line as player feedback
					mGun.enabled = true;
					mGun.SetPosition(0, transform.position);
					mGun.SetPosition(1, hitInfo.point);

					Health enemyHealth = hitInfo.transform.GetComponent<Health>();
					if (enemyHealth!= null)
					{
						//Apply damage to enemies
						enemyHealth.mDamage(mGunDamage);

						//Create Particles if hit enemy
					}
					else
					{
						//Create Particles if not hit enemy
					}
				}
			}
			else 
			{
				//Render the line as feedback
				mGun.enabled = true;
				mGun.SetPosition(0,transform.position);
				mGun.SetPosition(1, transform.TransformDirection(Vector3.forward)*1000);
			}
			//Apply firerate cooldown
			mCooldown = Time.time + mFireRate;
		}
		//Turn off line renderer 
		mCurrentCountDown += Time.deltaTime;
		if (mCurrentCountDown >= mGunCountDown)
		{
			mGun.enabled = false;
			mCurrentCountDown = 0.0f;
		}
	}
}
