Make it to where pressing a button on screen doesn't shoot a projectile?

I’m making a mobile game, that has a jump button and a tap to shoot system. My problem is that whenever you click the jump button on screen, the player will shoot at it, causing them to suffer delay, which makes a jump shoot maneuver not really work.

Here’s the code for shooting:

void Update()
        {
            if (Input.touchCount > 0) {
     
                 if (Input.GetTouch (0).phase == TouchPhase.Began) {
                     
                     if (Time.time > shotStart + shotCooldown)
                    {
                    anim.SetTrigger("Shooting");
                    Vector2 touchPos = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
                    Vector2 dir = touchPos - (new Vector2(transform.position.x, transform.position.y));
                    dir.Normalize ();
                    GameObject bullet = Instantiate (bomb, transform.position, Quaternion.identity)as GameObject;
                    bullet.GetComponent<Rigidbody2D> ().velocity = dir * bulletSpeed; 
                    shotStart = Time.time;
}
}

Thanks in advance~

You should verify if the current touch position is inside the desired gameplay area.
You can achieve that by using colliders, a rect or simply a canvas.
Then you’d have an auxiliary method to check for that collision.

That’d look a little bit like:

⠀
void Update()
         {
             if (Input.touchCount > 0) {
      
                  if (Input.GetTouch (0).phase == TouchPhase.Began) {
                      
                      if (Time.time > shotStart + shotCooldown)
                     {
                     anim.SetTrigger("Shooting");
                     Vector2 touchPos = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
                     Vector2 dir = touchPos - (new Vector2(transform.position.x, transform.position.y));
                     
                     // Here's the new and altered part
                     if ( ! IsInsidePlayArea(touchPos.x, touchPos.y))
                         return;

                     dir.Normalize ();
                     GameObject bullet = Instantiate (bomb, transform.position, Quaternion.identity)as GameObject;
                     bullet.GetComponent<Rigidbody2D> ().velocity = dir * bulletSpeed; 
                     shotStart = Time.time;
 }
 }

Also a little side recommendation:

  • You really should cache your bullets inside some data-structure, preferably an object-pool

I hope this helps!
