Question by Chacal1988 · Jul 03, 2014 at 12:43 PM · bulletaim

Cant shoot in the right axis

Hello, i have been burnin my head for hours triyin to solve this problema, but its really killing my. This is the thing, i have my left sided view game (just like Mario)and im triying to point my gun (wich have this script atached) towards the mouse position and is working perfect! But, when i try to shoot, my bullet only moves in the z axis, which is exactly what i dont want to happen. I want to shot in the exact direction that my gun is facing... Any way, i hope someone can help my. And sorry for bad english! Im from Argentina! :D

using UnityEngine; using System.Collections;

public class AimToMause : MonoBehaviour { public GameObject bullet; private Vector3 fwd; void Start(){

 }

 void Update() {

     fwd = transform.TransformDirection(Vector3.forward);

     Vector3 mousePos = new Vector3(Input.mousePosition.x, Input.mousePosition.y, 30);
     Vector3 lookPos = Camera.main.ScreenToWorldPoint(mousePos);
     lookPos = lookPos - transform.position;
     float angle = Mathf.Atan2(lookPos.y, lookPos.x) * Mathf.Rad2Deg;
     transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
     
     if (Input.GetButtonDown ("Fire1")) {
         Fire ();
             }
     
 }
 void Fire()
 {
     GameObject bullet1;
     bullet1 = Instantiate(bullet, transform.position, Quaternion.identity) as GameObject;
     //bullet1.rigidbody.AddForce(fwd * 500, ForceMode.Impulse);
     bullet1.rigidbody.AddForce(fwd * 10000);
     Debug.Log (bullet1.rigidbody.velocity);
 }    

}

Well, the only force you add to the bullet is fwd*10000. fwd always has the value you set here:

 fwd = transform.TransformDirection(Vector3.forward);

As Vector3.forward is a constant, every bullet will have the same direction.

So, you need to set fwd to the direction in which the bullet should move - my suggestion would be to add this after line 11:

 fwd = lookPos.normalized;

and get rid of line 5.
