Scroll view not scrolling if initial touch is a button

Things were working fine, and now I can't scroll my list unless I touch between the buttons in the list. So, I have to touch whitespace to scroll, otherwise it just thinks I'm trying to push the button. I don't think I changed anything and looking over settings nothing is popping out to me. Anyone know what might be causing this?

 

This is also affecting the mouse wheel. If the cursor is hovering over a button I can't scroll. It only lets me scroll if the cursor is over the empty space in between the button in my content container for the scroll rect. Is this a bug or did I break something?

 

Exactly same problem over here. Did you find some solution for this in the meantime?

 

Nope, no solution yet. This might be a bug, which would be lovely. Too many show stopping bugs in Unity right now... *peaks over at Unreal engine...*

 

what version are you using?

did a quick test and it's working fine in 5.1.1f, scrollwheel, click drag etc. ... perhaps you can explain how you've got your canvas/scroll/buttons setup a little more completely so we can work out what's going wrong?

 

The setup is exactly as it's shown in this tutorial. It has been working just fine for about a month now. It started requiring me to touch empty space to scroll shortly before I posted this. Since then I've updated to 5.1.0 and still doesn't work. I'll update to the most recent patch tonight and update this post.

I've been up and down the inspector on every element related to the scrolling content and have seen nothing out of place, and since the time it was working I've not touched a thing. Hopefully the patch just fixes it.

 

Updated to 5.1.1p2 and still not working. Here's screenshots of my setup.

 

Any updates on this? Seems to still be broken for me on 5.2.1p3

 

Oh we totally fixed this. It was super simple, but I wasn't the one to fix it.

If I'm remembering correctly we had the button script AND a pointer down event. One of the events was blank (no event registered) and once we removed the pointer down method (or maybe the button, don't remember) the problem was resolved. Hope that helps.

 

Use onClick event of button can resolve the problem.
myButton.onClick.AddListener( () => {myFunctionForOnClickEvent("stringValue", 4.5f);} );

 

Same problem here. Apparently, if a button gets EventTriggerType.PointerEnter attached, scrolling won't work if drag started on that button.

E.g. if you wanted to play a sound when mouse is over the button, you could do it this way:

Code (CSharp):

1. EventTrigger eventTrigger = button.gameObject.AddComponent<EventTrigger>();
2. var eventType = new EventTrigger.Entry();
3. eventType.eventID = EventTriggerType.PointerEnter;
4. eventType.callback.AddListener((e) => audioSource.PlayOneShot(buttonMouseoverSound, 1f));
5. eventTrigger.triggers.Add(eventType);

However, this will make the button block scrolling of a parent ScrollRect. So, can't have both scrolling and mouseover sounds for buttons.

I'd say it's a bug in Unity.

 

Same problem and got solution.. Before, I using EventTrigger component for event click and then change to button and boom I am so happy

Thanks for your clue
