Question Are there no built-in keyboard (or controller) support for moving component in UI?

I made scrollrect and add gridlayoutgroup.

And many childrens inside above group positioned rectangle.

Now, most want here keyboard (or controller) up/down/left/right move through children elements.

But there is no built in function for this?

I should make code everytime from scratch?

 

Do you mean UnityEngine.UI's built-in Navigation mechanism?

Unfortunately Unity seems to have wrecked / removed their old UnityEngine.UI documentation and replaced it with the new incomplete stuff, which does not appear to mention navigation anywhere that I can find.

If you google for

unityengine ui navigation

you can find some interesting bits still held on by Google.

 

yes thx for remind the word, Navigation,

So now, it can't be using?

 

I didn't write that. It's all in there. I just cannot find the Unity official documentation anymore, but parts of it can be dug up via Googling the above links. I have no idea what parts you need to know, so that's why I suggest googling.

 

googled but default input actions does not generated with premade settings, package already installed.

so when make input action, it comes with total blank. Most googled result comes with default settings I remember this was I got in few years ago unity version.

 

still unity there is so many void holes for just this basic element. I should make whole wheel reinvention again and again from scratch for most cases needed for just very simple game.

 

You don't need to reinvent this stuff. It's right there built in.

Only Selectable UI elements support built in navigation, such as buttons. So long as one is selected, then navigation events will work based on your settings.

Also need to ensure there's an event system present as well.
