UI Buttons to work continuously when pressed and held for sometime

Questions & Answers
1

Hi, so I have a UI Button which when pressed activates a FireNow() function, which fires a bullet. Now I want to fire continuously, so I have added OnPointerDownHandler and OnPointerUpHandler to my code. But I am not able to access these functions in my FireNow function. This is the code. How do I access them in FireNow(). The Shoot() function performs the real shooting.

public void OnPointerDown(PointerEventData eventData)
{
ispressed = true;
}

public void OnPointerUp(PointerEventData eventData)
{
    ispressed = false;
}

// Update is called once per frame
public void FireNow () {

    if (isreloading)
        return;                             //if reloading then don't go ahead

    if(currentammo<=0)                      //if we have no ammo
    {
        StartCoroutine(Reload());           //reloading done here through coroutine
        return;                             //don't go ahead in this function
    }

    if (Time.time >=nextTimeToFire && ispressed)            //Input.GetButton("Fire1") and Time.time adds real time              
    {
        Shoot();                                            //function to shoot when left mouse button is clicked
        nextTimeToFire = Time.time + 1f / 11f;                          //shows which is the next time to fire
    }
}

Simply call your function in Update while isPressed == true

public void OnPointerDown(PointerEventData eventData)
{
    ispressed = true; 
}

 public void OnPointerUp(PointerEventData eventData)
 {
     ispressed = false;
 }
 
 private void Update()
 {
    if( isPressed ) FireNow();
 }
 
 // Update is called once per frame
 public void FireNow () {
     if (isreloading)
         return;                             //if reloading then don't go ahead
     if(currentammo<=0)                      //if we have no ammo
     {
         StartCoroutine(Reload());           //reloading done here through coroutine
         return;                             //don't go ahead in this function
     }
     if (Time.time >= nextTimeToFire)            //Input.GetButton("Fire1") and Time.time adds real time              
     {
         Shoot();                                            //function to shoot when left mouse button is clicked
         nextTimeToFire = Time.time + 1f / 11f;                          //shows which is the next time to fire
     }
 }
