Please ensure to include replication steps and, if possible, the script you're using to initialise the control.

@Jamjardavies

I'll take a quick look to make sure I'm not doing something silly, but was strange seeing errors when there were no children in the Content transform... I'll remove the changes I've done just in case that caused issues elsewhere...

It would be tricky to share code as it's using Zenject as the main DI, but I can see if I can make a repro in a new project.

Jamjardavies

@Jamjardavies

Okay in my tests on a new project, I've added a "Content Scroll Snap Horizontal" from the create menu, and then removed the 5 children it comes with. I get no errors until I play and stop, to which I notice the ContentScrollSnapHorizontal has set it's enable to false. Upon enabling this component in the editor (in edit mode, not play mode), I start getting error spam in the console. Also, when adding children to the content using Awake, it works, but if I delay it (in Start for instance), it then doesn't work or snap. What I seem to need to do is enable the snap, and update the layout, but this still causes an exception, since there's no children at the start.

Jamjardavies

@Jamjardavies

Note: I also use a Horizontal Layout Group to align the children, that seems to also make it mis-align when adding (most likely due to delay of the layout code)

Simon (Darkside) Jackson

@SimonDarksideJ

Thanks @Jamjardavies , can you please ensure you include all that detail in the issue log on the Bitbucket site.

Hi all, firstly thanks for the great tools/extensions!! I am just dipping my toe with the conflict manager and I have a quick question:

Ive prefab'd a horzontal slider (holder) to populate dynamically. Im struggling with trying to set the ParentScrollRect through code in my loop. I have a vertical scroller in the scene awaiting the prefab objects.
Any suggestions of best way to tackle? ps ive used the search and found a post of similar but ultimately not ending in a strategy

Simon (Darkside) Jackson

@SimonDarksideJ

Big push tonight to get some of the finishing touches for the next release of the UI Extensions in, including:

New Magnetic Infinite scroll control
Programmable goodness added to the UI Knob control to set its value
New touchable mask for the UI Knob control to increase the surface area to control the knob (new example too)
A few reworked fixed to support 2018, mainly due to the new Input System wrapper
Finalised testing and updating of the examples back to 2018

(one day I will remember to only add or fix examples in Unity 2018, because Unity... Backwards compatibility is fun...)

So hopefully should have the 2.2.3 release out shortly after a few last checks through the worklist.

Apologies @flamindelux_twitter , just spotted your message

As ever @flamindelux_twitter . could you log your request as an issue on the Bitbucket repo, and if possible, include a sample (replica?) scene for what you are trying to achieve and include detailed replication instructions.

Simon (Darkside) Jackson

@SimonDarksideJ

Ok, @flamindelux_twitter , done a quick bit of digging and I can see the issue. In fact in your use case you should be seeing a null-reference exception in the log when you try and assign the parent scroll rect through code.

Working on a fix now

Simon (Darkside) Jackson

@SimonDarksideJ

OK, fix pushed to development @flamindelux_twitter , will be in the next release. (or you can grab the development version, just check the UPM docs for information)

Simon (Darkside) Jackson

@SimonDarksideJ

OK, Can replicate your null ref issue @Jamjardavies , will post an issue log from your description above and see what I can do

Simon (Darkside) Jackson

@SimonDarksideJ

@Jamjardavies I've created your issue on the bitbucket site.
https://bitbucket.org/UnityUIExtensions/unity-ui-extensions/issues/354/content-scroll-snap-raises-exception-when
Stay tuned for more details

Simon (Darkside) Jackson

@SimonDarksideJ

And the issue with the ContentScrollSnap is resolved @Jamjardavies and the fix is in the development branch.

Jamjardavies

@Jamjardavies

@SimonDarksideJ Ah sorry, been busy with rapid fast sprints so wasn't able to populate a full repro.

I put in some fixes locally to get it working quickly. Here's the two fixes I've done:
https://bitbucket.org/kuato-studios/unity-ui-extensions/commits/dc357a42aa29824bac11cb46eba9d64ccad868db

Simon (Darkside) Jackson

@SimonDarksideJ

Well, if it helps, you can check out the changes in this PR which resolves the issue.
https://bitbucket.org/UnityUIExtensions/unity-ui-extensions/pull-requests/103

That way you'll be aligned with the official updates when they drop. ANy issues @Jamjardavies , let me know and I'll update the project if you find something doesn't work for you

There is even a new method that was added, to enable adding items programmatically and have the control still operate as expected, works with both prefabs and code built items

Simon (Darkside) Jackson

@SimonDarksideJ

OK, final call before the next release is pushed. Two pending PR's need some help testing.

Simon (Darkside) Jackson

@SimonDarksideJ

Particle system PR merged, tested on several scenes and works as expected.

Simon (Darkside) Jackson

@SimonDarksideJ

Last PR merged. Any last calls before I kick the next release out?

Update 2019.5 - 2.3 - Accelerated Deployment

Since the move to UPM, the team have been able to react quicker and push out fixes a lot easier, without affecting previous installation (whilst still adhering to Unity's backwards compatibility pattern). So it is with great news we announce this new release, faster that ever :D (and thanks to UPM, easier to upgrade than ever).
Be sure to also check out the "Examples" option in the Package Manager window to import the samples to your project.

Be sure to logon to the new Gitter Chat site for the UI Extensions project, if you have any questions, queries or suggestions
Much easier than posting a question / issue on YouTube, Twitter or Facebook :D

@pdeclercq

Hey! I found out about this extension a few days ago and it's been game changing. My current game's gameplay is pretty much menus on top of menus and UI wasn't really on point and smooth so thanks a lot for the dedication. I just want to report a very small glitch with the HorizontalScrollSnap (probably with the Vertical one too) where if you ask dynamically to move to an index if you don't deactivate the velocity, it scrolls to the next one (only happened to me at very low velocity). Thanks again for your work !

Simon (Darkside) Jackson

@SimonDarksideJ

Thanks for the feedback @pdeclercq , Can you log an issue on the bitbucket with replication steps and of possible a demo scene showing the issue.

papitosan

@papitosan

Hello! It maybe very simple but I can’t get the centered/selected page number in the Horizontal Scroll Snap.

I searched on the web but still not able to get this variable.

‌

Could you tell me step by step how to access this variable from a script?

‌

Thank you very much for this great extension!

Simon (Darkside) Jackson

@SimonDarksideJ

Both the Horizontal and Vertical Scroll snaps have a "CurrentPage" variable, which indicates the currently "snapped" page.
I've noticed the documentation only reflected properties available in the inspector and have updated them to include this property. Sorry for the confusion
https://bitbucket.org/UnityUIExtensions/unity-ui-extensions/wiki/Controls/HorizontalScrollSnap

papitosan

@papitosan

Hey thanks. "To get access to the Current or snapped page in code, use the CurrentPage property details above". So where do I reference this variable? I tried to write "public int CurrentPage" in HorizontalScrollSnap script but without success.

Simon (Darkside) Jackson

@SimonDarksideJ

Simply query the CurrentPage variable of the HorrizontalScrollSnap component, as follows:

    public HorizontalScrollSnap hss;

    // Start is called before the first frame update
    void Start()
    {
        hss = GetComponent<HorizontalScrollSnap>();
    }

    // Update is called once per frame
    void Update()
    {
        //Checking for the Currentpage
        var theSelectedPageIs = hss.CurrentPage; 
    }

As shown in the last line, I query the reference I have to the specific GameObject with the HorizontalScrollSnap component applied, and query the "CurrentPage"

pdeclercq

@pdeclercq

Thanks for the feedback @pdeclercq , Can you log an issue on the bitbucket with replication steps and of possible a demo scene showing the issue.

I'm not 100 % sure how to replicate it, i can't send a demo because as i said i found a solution (and didn't really think things through), but the main point is, if you move to a index using GoToScreen(index) while the scrolling is decelerating, it can go to the index + 1 or - 1 depending on the velocity (left to right / right to left)

I would love some help on the same scroller tho, im trying to delete or add children dynamically but i don't understand the RemoveChild() parameter "out". I'm using c++ in all my own script so the issue might be there but no real idea

pdeclercq

@pdeclercq

What I really want to do is to be able to hide a specific screen so the scroller ignores it

Simon (Darkside) Jackson

@SimonDarksideJ

I saw you logged an issue on Bitbucket for the same. As your requirements are slightly different here. Could I ask you to update that issue with the requirements for what you are trying to achieve and if possible, yes a sample scene to work with.

papitosan

@papitosan

Simply query the CurrentPage variable of the HorrizontalScrollSnap component, as follows:

    public HorizontalScrollSnap hss;

    // Start is called before the first frame update
    void Start()
    {
        hss = GetComponent<HorizontalScrollSnap>();
    }

    // Update is called once per frame
    void Update()
    {
        //Checking for the Currentpage
        var theSelectedPageIs = hss.CurrentPage; 
    }

oh I understand now, Thanks a lot. I was trying to reference the variable directly in HSS script.

Also I forgot to declare "namespace UnityEngine.UI.Extensions"

papitosan

@papitosan

Excuse me to bother you but I have one last question:

I want to have a menu where each page correspond to a level but at the beginning all level except level 1 would be locked so it would n't be possible to scroll to those page. then after completing level 1, level 2 become available and unlocked so you can now scroll to the page. How would you do that with HSS?

pdeclercq

@pdeclercq

@papitosan you can add a button on each screen and deactivate the interaction for the one locked or just add a new child if you don't want to show the level at all

papitosan

@papitosan

@pdeclercq Ok, got it!

for people who try to do it, it's not possible to make a child of a prefab. You have to put the plans on the scene as gameobject first and then call them by script as child.

JustWastingTime

@JustWastingTime

Hello. Is it possible to make the reorderable list grid scrollrect to scroll while clicking on the content? I disabled the IsDraggable to prevent the content from getting dragged instead. Or is there another UI Extension component that lets me make a grid with autolayouting?

Simon (Darkside) Jackson

@SimonDarksideJ

The Reorderable List, is only intended as a drag and drop interface and is designed that way @JustWastingTime , the component you're looking for is the "UIScrollToSelection" Component. The docs page was missed in the last big update, so I'll get it updated ASAP.
However, it is very easy to add, by simply adding the component to an existing ScrollRect

mahgo

@mahgo

I'm using UILineRendererList to render multiple lines, and am trying to style my lines with a sprite that I want to repeat/tile, but it is only stretching, even if I set Wrap Mode - Repeat on the sprite. What can I do to achieve this?

Artyom

@artyomabgaryan

@SimonDarksideJ is there way to use Scroll Snap & infinite scroll together ?

Simon (Darkside) Jackson

@SimonDarksideJ

You can use the HSS & VSS controls with the Infinite scroll control @artyomabgaryan . they have been updated to work together
