Gunshooting Top Down

Unity Engine
1

Hey guys!

I have a little problem with my Gunscript in a Top Down Shooter.
Look at the GIF to see my Problem :smile:

My Problems are the different bullet speeds depending on the distance between spawn and cursor and the “backshooting”

Weapon Script

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

public class Weapon : MonoBehaviour {

    public enum WeaponType { oneHanded, twoHanded, DualHanded }
    public WeaponType weaponType = WeaponType.oneHanded;

    public enum FireMode { Automatic, Manual}
    public FireMode fireMode = FireMode.Automatic;


    public SetTorsoSprite Torso;
  
    public float fireSpeed;

    public Rigidbody2D bullet;
    public float bulletSpeed;

    public GameObject muzzleFlash;
    public Transform muzzlePos;


    public Camera mainCam;
    public float offset;

    public bool canShoot;
  
    void Start () {
        Torso.SetSprite((int)weaponType);
    }

    void Update()
    {
        if (fireMode == FireMode.Automatic)
        {
            if (Input.GetButton("Fire1"))
            {
                if (canShoot)
                {
                    StartCoroutine(Fire());
                }
            }
        }
        else if (fireMode == FireMode.Manual)
        {
            if (Input.GetButtonDown("Fire1"))
            {
                if (canShoot)
                {
                    StartCoroutine(Fire());
                }
            }
        }
    }
    IEnumerator Fire()
    {
        Vector3 mousePos = Input.mousePosition;
        mousePos.z = 5.23f;
        Vector3 objectPos = Camera.main.WorldToScreenPoint(transform.position);
        mousePos.x = mousePos.x - objectPos.x;
        mousePos.y = mousePos.y - objectPos.y;
        float angle = Mathf.Atan2(mousePos.y, mousePos.x) * Mathf.Rad2Deg;
        GameObject muzzle = Instantiate(muzzleFlash, muzzlePos.position, Quaternion.Euler(new Vector3(0, 0, angle )));
        Rigidbody2D bPrefab = Instantiate(bullet, muzzlePos.position, Quaternion.Euler(new Vector3(0, 0, angle + offset))) as Rigidbody2D;
        bPrefab.AddForce(mousePos * bulletSpeed);
        canShoot = false;
        yield return new WaitForSeconds(fireSpeed);
        canShoot = true;
        StopCoroutine(Fire());
    }
}

Thanks in Advance !

rubs crystal ball so… the bullets going at different speeds? (just the gif on it’s own gives us no concept of what you are trying to achieve… words and a picture would be much better)

you want to make the vector you are using as a direction for the bullet a “unit” vector first so that’s it magnitude doesn’t affect the result.

Hi,
yes i mean different speeds based on the distance between spawn and cursor. Also the Backshooting

EDIT:
Just solved myself.
Instead of using the Cursor Position i just used my Players direction (transform.up) to add Force
