Raycast always hitting the same place even if I click different areas?

Question

void Update() { RaycastHit hit; if (cm.glareOn == true) { if (Input.GetMouseButtonDown(0)) {

             GameObject bullet = Instantiate(lightbullet, Input.mousePosition, Quaternion.identity);

             if (Physics.Raycast(origin.transform.position, origin.transform.forward, out hit))
             {
                 Debug.Log(hit.transform.position);
                 bullet.transform.position = Vector3.MoveTowards(origin.transform.position, hit.transform.position, speedbullet * Time.deltaTime);
             }
         }
     }
 }

hit.transform is returns the Transform of the object hit by thee raycast, not the raycast impact point

              bullet.transform.position = Vector3.MoveTowards(origin.transform.position, hit.point, speedbullet * Time.deltaTime);

Several other notes about your code:

Instantiate(lightbullet, Input.mousePosition, Quaternion.identity);. Input.mousePosition is a screen-space position, not a world space position. You most likely want to spawn the bullet at the barrel's position (maybe origin.transform.position?)

Moving the bullet once under Physics.Raycast does not really make sense. You most likely want your bullet to travel on its own over time. You'll find several examples on the web to help you with that.

Then, please explain the actual issue you are facing. Images may help.

Have you solved the two other issues I've mentioned?

So basically I managed to get it to shoot now, thank you for your suggestion :) but it still only shoots in one direction no matter where I click. alt text it only shoots in that direction and I can't get it to change. Also I made a new script for the bullet void Update() { transform.position = Vector3.MoveTowards(transform.position, am.target, 30 * Time.deltaTime); }

so it is shooting properly now but still only to one point and not the point i am clicking

I am sorry if it is unclear and thank you for all your help!

Perhaps do it something like:

 bullet.transform.position += new Vector3(0, 0, speed);

Or:

 bullet.transform.position = Vecto3.Lerp(transform.position, hit.point, speed);

where speed is how fast the bullet moves. Put these in FixedUpdate(). If you want them in Update() multiply speed by Time.DeltaTime.

thank you, but i think my problem is that the raycaster only hits one area. the object in front of the camera has a box collider but it still can't seem to hit it(it hits the back plane) and the hit point doesn't change no matter what ,:)
