2D top down shell ejection

Hi, I’ve been trying to figure this out for days. Some codes I’ve tried work but not as quite as i want it to work. I have the shell ejection working fine when I use transform.translate but when i use AddForce the shells just floats to the left. I finally have the shell to rotate on its own axis as other codes i have tried would rotate it according to the position of its parent, which shows the shell floating all over the place. I also have a box collider comp on the shell but set as is triggered so it would not collide with the player collider. Not sure if that matters.

What am I doing wrong?

Any help will be appreciated!

My code:public class ShellEjectionCtrl : MonoBehaviour {

public float ejectSpeed;
public float rotspeed;

void FixedUpdate(){

	transform.Translate(new Vector2 (-2,ejectSpeed)*Time.deltaTime); //this code works properly the shell gets affected by gravity but rotates weird like it has a point of rotation.

	GetComponent<Rigidbody2D> ().AddForce (new Vector2(-2,ejectSpeed));//this code makes the shell float to the left position but shell rotates properly

	GetComponent<Rigidbody2D> ().AddTorque (Random.Range (0, rotspeed));//rotates the shell not relative to its position i.e ejection port of the rifle
	Destroy (gameObject, 2.0f);											

}

}

Well, it’s physics. When a shell is ejected, it only gets the force applied as it’s actually ejected, not when it’s flying through the air. You need to add the force and torque at the moment of ejection, and just let the physics system handle it from there.
