Shooting Script Bullet Doesnt Fire

Questions & Answers
1

I had a working script, then somewhere along the line something got deleted and I cannot figure out how to get back to where is was. I have a driveable tank with a game object attached to the end of the barrel that fires projectiles on a left mouse click. With the following script however, my bullets spawn but dont move. What have I miscalculated?

using UnityEngine;
using System.Collections;

public class fireBullet : MonoBehaviour {
	
	public Rigidbody bullet;
	public float cannonPower;
	
	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
		//fire cannon
		if(Input.GetButtonUp("Fire1")){
			
		//create projectile at location script is attached to
			Rigidbody instance = Instantiate(bullet, transform.position, transform.rotation) as Rigidbody;
		
		//add force to projectile
			Vector3 fwd = transform.TransformDirection(Vector3.forward);
			instance.AddForce(fwd*cannonPower);
			
		}
	}
}

Maybe it get stuck with the collider, try adding this:

Physics.IgnoreCollision(bullet.collider, transform.root.collider);

or

Physics.IgnoreCollision(instance.collider, transform.root.collider);

You wrote GetButtonUp, but you may want try to replace it by GetButton or GetButtonDown.
