Loading spinner animation

[Matt_SF]

@Sawer use a timer and Engine.getPreloadProgress()

https://docs.hise.audio/scripting/scripting-api/engine/index.html#getpreloadprogress

[Sawer]

@Matt_SF Thanks, Matt.

Just wondering where I should Implement the function?
Will This preload method occur also after the user selected the samples folder?

[Matt_SF]

@Sawer I've use it once quite some time ago, so I'll have to check how I implemented it but it's simple. I'll take a look when I'm at my computer

[Sawer]

@Matt_SF Thanks so much, waiting.

@Sawer IIRC : when loading new samples (i.e. by use of a button or menu) > start a timer which will get periodically the loading state. You'll get a value from 0.0 to 1.0 which you can use either to run a loading bar, or make a spinner run until the value is 1.0

[Sawer]

@Matt_SF Thanks for answering, however I dont know if I got your answer right.

What's IIRC?
Where in the code should I implement this? C++ side or Hise IDE side?

Maybe I should give more context of the outcome I'm thinking about:

For instance; User purchase product and installs it in the computer. Then the user opens the plugin in daw, it takes like 5/6 seconds to ask samples folder. After the user selected samples folder, it takes another 5/6 seconds again to show the alert window.

In between these waiting seconds, the spinning loadng progress will animate there.

Hope It is clear now. Thanks

@Sawer IIRC stands for "If I recall correctly"

You have to implement this in HISE. But the loading callback only fires when you change the sample content.
If it's not the case you'll have to find a way to implement a timer which will display a spinner according to something else.

This is what the docs says about the loading callback :

https://docs.hise.audio/scripting/scripting-api/scriptpanel/index.html#setloadingcallback

To display a spinner when changin samples, you should write :

if(isPreloading)
     t.startTimer(x);
else
   t.stopTimer();

In the timer you'll make the spinner move.

Edit: fixed typo

@Matt_SF typo in that code...

[d.healey]

This is how I'm doing it https://codeberg.org/LibreWave/RhapsodyBoilerplate/src/branch/main/includes/Spinner.js

[Matt_SF]

@DanH yeah I just tossed it like that to give an idea. It was not meant to be used as is . I just corrected it.

@Matt_SF @d-healey Agreed with consensus that the place to do this is in HISE. I'm using Lottie here, hit me up if you'd like more info/code.

[Dan Korneff]

@clevername27 please do. I'm looking at adding lottie to my next project. I've only tinkered with it briefly in the past

[d.healey]

@Dan-Korneff I have a video about using lottie in HISE (might only be available for Patrons at the mo though).

[Dan Korneff]

@d-healey I'm a subscriber :)

[d.healey]

@Dan-Korneff Thanks :)

[clevername27]

@clevername27 See my next post. There's a great example in the documentation, though, that shows you exactly how to do it. The short answer is, "manually" lol.

[Sawer]

@clevername27 @d-healey @Matt_SF Thanks so much for replying here.

Should the code be implemented in "onInint" callback right?

[clevername27]

@Sawer Not sure I understand the question. Have you seen this? Cheers.

[Matt_SF]

@Sawer put anywhere in you UI script == can be on init or in an include file. Remember to defer your UI script :

[Sawer]

@Matt_SF @clevername27 @d-healey Thanks so much for the reply.

However, the loading of the samples appears to happen in C++ side(somewhere in Frontendhandler.cpp) , based on what I’m understanding. I tried to implement the code provided but I still think that I do not have a proper context of how to apply
Here below is a video:

Hope the video explains my point .
