OnMouseDown doesn't work on a button

Hello I tried starting up unity and add this simple script to a button but it just doesn't seem to work.
I tried adding the script to buttons, panel's but the console just does nothing.

using UnityEngine;
using System.Collections;

public class Click : MonoBehaviour {
void OnMouseDown() {
print ("click");
}
}

this is a simple canvas with a panel and a button on It, there's just so little I can do wrong that I don't know why it won't work

 

OnMouseDown() is used to detect tap on objects in your scene. Although Button is also an object, it is different in the sense that Unity gives you functionality to attach it's tap listener built-in and I guess OnMouseDown is not supposed to work on UI components (although I feel that if you attach a collider to your button, OnMouseDown might also work, but I haven't tried it). Just drag-drop a gameobject from hierarchy onto the button's On Click() in inspector, and choose a public method that you want called on button click.

 

And what if I want to write the method myself I want to use on that button?

 

One way is what I've described in my previous post. The other is to get reference of the button, then register it's event handler at runtime. It would look something like this :

Code (csharp):

1. Button a;
2.  
3. void Start()
4. {
5.     a.onClick.AddListener(() => {Debug.Log("Button a was clicked");});
6. }

 

If you want if any Button is pressed the code can look like this! You can request it like this in the Update function i hope it helps you a little! And of course sorry for my bad english..

Code (CSharp):

1. public void Update()
2.     {
3.         if (Input.anyKeyDown)
4.         {
5.             Debug.Log("Any Key is pressed!");
6.             // And here you can call any function if y want
7.             // anyFunction(ParaType paramName,...);
8.         }
9.     }

 

The best way to do everything you want with a button is to use the new onClick implemented function; so create a new UI button and a script like the one below. Than attach it to a GameObject, like the main camera. Once you've done it click on the button you've created in the Hierarchy and drag with the mouse the Main camera from the Hiearchy to the box below the OnClick() sentence. You'll see another box above will appear, so select from it the script you've created (i named it "Try") and, from it, the public void you've created(that i named "TryTheClick()"). You have to create a PUBLIC void to allow the system interact with it
So play start and try to click your button.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Try : MonoBehaviour {
5.  
6.     public void TryTheClick()
7.     {
8.         Debug.Log("Clicked !");
9.     }
10.  
11. }
12.  

 

That seems like so much work for a rather simple thing to do.. But maybe it's me not understanding everything about it. I've looked at a few other examples, trying to get my button's onClick to work too, but everyone seems to suggest, what I feel are, complicated solutions. Oh well

 

i have used this way and it works. but I don't know how to hack if the button is released. When the button is pressed i want the bool to be true but how do i make it false when it is released? please help!
