How to handle "a lot" of objects in a scrolling collection? #8817

Closed dtb49 closed 9 months ago

dtb49 commented 3 years ago

Overview

So I recently upgraded to the 2.5 release so that I could use the new scrolling object. I created a rather large list of items consisting of about maybe 50-60 text buttons from the mrtk and it seemed to really kill the app performance.

There's really nothing special about the buttons other than just a simple label on them. Even if I configure it to only show like 4 buttons at a time it still doesn't really help the performance of it at all. I kind of expected that if the buttons were disabled it would help with the performance but, this doesn't seem to be the case.

Is there a a way to optimize this? Or should I try to create some other controller to limit the number of items in the scroll view at a time?

Any help or advice would be greatly appreciated!

Unity Version

2019.15

Hi @dtb49 What MRTK button prefab are you using?

dtb49 commented 3 years ago

@vaoliva it looks like it is the Button prefab found under MRTK/SDK/Features/UX/Interactable/Prefabs

vaoliva commented 3 years ago

@dtb49 I was trying to reproduce the issue, by adding 100 x "PressableButtonHololens2_NoLabel" prefabs which contains 5 renderer children each. All of them using the correct material for clipping. But I couldn't replicate a perf hit like you describe. Could you try to use those instead of the regular Pressable Buttons? Also bear in mind, sprite dafault material are not well supported with the Scroll.
