How to set Box collider size and offset correctly?

I've created a button and attached it to the canvas inside the scene. I also added the BoxCollider2D component to the button. Then I added the script and bound it to the button. (See screen 1).
The text of the script is:

using UnityEngine;



public class SkipButton : MonoBehaviour

{



    // Start is called before the first frame update

    void Start()

    {

        Debug.Log("Button started");

    }



    void OnMouseDown()

    {

        Debug.Log("Mouse down");

    }



}

Then I start debugging and click the button, nothing happens (see screen 2).

When I dramatically increase the size of Box Collider, the event fires (see screen 3).

What am I doing wrong?
I would appreciate any advice or link to the articles or books related to my issue. Thanks!

 

First of all, is there a reason you're not using the inbuilt button click function and are trying to bypass it? I suspect what's going on is the two are interfering.

I should also note, this sounds much more appropriate to the UI forum than here.

 

I want to implement two different functionalities which will differ by the duration of the button pressed.
Maybe I should use another component for this?

 

You should just use the standard button. You shouldn't have to manually edit the collider to get it working. You don't even have to add the collider yourself.

Also, please use code tags when posting code around here. If you notice, blindly posting code into your post causes it to loose formatting. And, @Derekloffin is correct. This post really belongs in the UI section.

 

thanks for your reply. code tag added, sorry for the inconvenience, I'm a beginner.

 

no problem, were you able to get the button working?

 

Unfortunately wasn't. Tried different approaches, including the deletion of the collider. Click works, MouseDown - not.
My next ideas are
1. In videos and text guides sizes of colliders are smaller than in my scene - 1-2 against 150 points. Maybe I can decrease the scene size. Maybe it can help.
2. If not, I'm going to use sprites instead of buttons.

 

Is your OnMouseDown method on a script attached to the same gameobject with the collider? If not, I don't think it will fire.

 

See Screen 3 - if I increase the Collider size the event fires. So I assume that the problem is in the geometry or something around it

 

Does backimage have a collider? It might just be that another collider is getting the event until you resize the button collider enough that it gets it. I think you have overlapping colliders somewhere.

 

It hasn't.
Also, to check your idea I've added next code to the script

    void Update()

    {



         if (Input.GetMouseButtonDown (0)) {

              Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

             RaycastHit hit;

              if (Physics.Raycast(ray, out hit)) {

                 Debug.Log ("Name = " + hit.collider.name);

                 Debug.Log ("Tag = " + hit.collider.tag);

                 Debug.Log ("Hit Point = " + hit.point);

                 Debug.Log ("Object position = " + hit.collider.gameObject.transform.position);

                 Debug.Log ("--------------");

              }

              else

              {

                  Debug.Log ("nothing caught");

              }

         }

    }

when I click left mouse button anywhere only "nothing caught" repeats in the debug window

 

Created a new project, added a scene, a button, a script - sam result. Added Collider - same result.

 

Maybe you can also give me a hint on my main problem, please?
