Run a function aslong as a button is pressed

Question

Hi

I have a button in my canvas. I know how to make a button run a function whenever its pressed, but how do I make it run the function as long as I hold the button down.

To be more clear i'll give you an example :

I have a bool that needs to be turned on and off ( on when the button is pressed, and off if its not pressed)

e.g. :

public void W$$anonymous$$leButtonIsPressed(){ myBool = true;

}

public void W$$anonymous$$leButtonIsNotPressed(){ myBool = false;

}

long story short : I want my bool to be true if the button is held down, and false if its not.

Thanks in advance.

t$$anonymous$$s code will work..

using UnityEngine; using System.Collections; using UnityEngine.EventSystems;

public class ButtonPressed : MonoBehaviour, IPointerDownHandler, IPointerUpHandler {

 // Use t$$anonymous$$s for initialization
 void Start () {
 
 }
 void Update()
 {
     if (!ispressed)
         return;
     // DO SOMETHING HERE
     Debug.Log ("Pressed");

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

}

Its possible by many different ways but choose any suitable for your case. For UI button than you can refer t$$anonymous$$s http://answers.unity3d.com/questions/857801/46-ui-dynamic-button-event-system-pointerenter-poi.html

If UI it not mandatory in your case You can also do it with GUI button than use Repeat Button http://docs.unity3d.com/ScriptReference/GUI.RepeatButton.html

In case of touch device input http://docs.unity3d.com/ScriptReference/TouchPhase.html
