how to fire with limited bullet ?

Question

here is my code i just need to fire only 3 bullets but i dont understand how to do it

public Transform[] firepoint; public Transform firepoints; public Transform Firepoint; public GameObject bulletPrefab; public GameObject RocketPrefab; public GameObject GernadePrefab; public GameObject LandMine; private int currentBullets = 0; private int totalbullets = 4;

 public float BulletForce = 20f;
 public float GernadeForce = 20f;

 // Start is called before the first frame update
 void Start()
 {
     
 }

 // Update is called once per frame 
 void Update()
 {
     if (GameManager.Instance.isGameInPlay == true)
     {
             if (Input.GetKeyDown(KeyCode.LeftControl))
             {
                 if (CarController.instance.CurrentWeapon == 1)
                 {
                     Shoot();
                 }
                 if (CarController.instance.CurrentWeapon == 2)
                 {
                     BulletShoot();
                 }

                 if (CarController.instance.CurrentWeapon == 3)
                 {
                     Gernade();
                 }

                 if (CarController.instance.CurrentWeapon == 4)
                 {
                     Landmine();
                 }
             }
     }
     
 }
 void BulletShoot()   
 {
     if (currentBullets > 0)
     {
         foreach (var firepoint in firepoint)
         {
             GameObject bullet = Instantiate(bulletPrefab, firepoint.position, firepoint.rotation);
             Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
             rb.AddForce(firepoint.up * BulletForce, ForceMode2D.Impulse);
         }
         

     }
     else
     {
         currentBullets = totalbullets;
     }
 }
 void Shoot()
 {
   

         GameObject bullet = Instantiate(RocketPrefab, firepoints.position, firepoints.rotation);
         Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
         rb.AddForce(firepoints.up * BulletForce, ForceMode2D.Impulse);
     
 }

 void Gernade()
 {
     GameObject bullet = Instantiate(GernadePrefab, firepoints.position, firepoints.rotation);
     Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
     rb.AddForce(firepoints.up * GernadeForce, ForceMode2D.Impulse);
 }
 
 void Landmine()
 {
     GameObject bullet = Instantiate(LandMine, Firepoint.position, Firepoint.rotation);
     Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
     rb.AddForce(Firepoint.up * GernadeForce, ForceMode2D.Impulse);
 }

If you mean fire multiple bullets, then you should make a

  public int bulletNumber

When button is pressed loop through that many times:

 for(int i = 0; i < bulletNumber; i++)
 {
     //Your firing code here
 }

A bullet isn't likely to go off when you drop the cartridge for various reasons, including how it lands. Most dropped bullets land tip first on a floor or the ground. When this happens, the bullet will land in a way that prevents the impact from being sufficiently forceful to cause the bullet to fire.

I'm not sure exactly what you are trying to achieve but I suspect that you want the bullets to fire sequentially.

In your bulletShoot() method you need to test if the number of bullets fired is greater than or equal to the number you want to allow.

Something like this:

 if(currentBullets < 3) 
 {
      /* code to fire your bullet */
      currentBullets++;
 }

You could then decrease currentBullets by one when a bullet hits it's target or exceeds it's max range.

You might also want to add a time delay between the bullets. This can be done like this.

  if(currentBullets < 3 && Time.time > lastFired+1) 
     {
          /* code to fire your bullet */
          currentBullets++;
          lastFired=Time.time;
     }

This will give a delay of one second between bullets.
