[FPSGame] gun's muzzlePoint rotation Update Problem

Questions & Answers
1

my biggest problem is :

I am making a commercial FPS Game and i am stuck on MuzzlePoint’s Rotation.
i want my Bullet Tracer go from the muzzlePoint’s current location to center of the screen (crosshair’s center).

my Incomplete Script:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class AssaultRifle : MonoBehaviour {

	public float currentBullets;
	public float bulletsPerMag;
	public float fireRate;

	public GameObject muzzlePoint;
	public Camera FPSCamera;

	float firetimer;

	bool isReloading;

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
		if (Input.GetKey (KeyCode.Mouse0) && currentBullets < 0) {
			Fire ();
		}
	}

	void Fire()
	{
		if (isReloading)
			return;

		RaycastHit hit;
		if (Physics.Raycast (FPSCamera.transform.position, FPSCamera.transform.forward)) {
			// What to do here ????
			// muzzlePoint.transform.localRotation = hit.point;  Failed!!!   :(
		}

		if (firetimer < fireRate)
			firetimer = Time.deltaTime;
	}
}

all i want to do is keep the rotation of MuzzlePoint to the raycasthit hit’s hit Location…

plzz helpp !!! :frowning:

Firstly, hit.point is of type Vector3, meaning it returns a single point in 3D space. You’re trying to apply a rotation (which is of type Quaternion) from a Vector3 so you’re getting a type mismatch. You can’t directly cast a quaternion to a Vector3, you need to multiply it by a vector.

Now, if all you want to do is make the bullet tracer go from the muzzle point to the point where the raycast hit, you could just do this (assuming you’re rotating the camera and the player independently):

GameObject bulletTracer = Instantiate(bulletTracerPrefab, muzzlePoint.transform.position, Quaternion.Euler(FPSCamera.transform.rotation.eulerAngles.x, player.transform.rotation.eulerAngles.y, 0f) );

Also assuming you have a GameObject called ‘player’ so it can get the euler angle from that object. I’ve just tried this and it works fine.

I hope I was able to solve your issue. Good luck, and happy coding.

@SonicScrew12 I Didn’t mean that !!

I Mean i want to instantiate the tracer at the gun’s end and move it to the center of the screen and at the same time, making it charge forward…

for example IN SHORT - - when u see bullet tracers in Call of Duty - Modern Warfare 3
