ScrollViewer not available in babylonjs-gui NPM package (3.3.0)?

Bugs
1

I’m using the latest NPM package for babylonjs-gui, but I can’t seem to find the ScrollViewer class. I’m using TS, and types are set up correctly, I can use all controls except the scrollviewer.

Also, I searched for ‘scrollviewer’ in node_modules/babylonjs-gui/babylon.gui.min.js and got no results.

hello!
the scrollviewer is a new feature of 4.0:

Sweet, thanks!

Hmm, after upgrading to 4.0.0-alpha.22, I am getting this error on the first draw call:

Uncaught TypeError: Cannot read property 'registerStep' of undefined
    at e.register (babylon.js:16)
    at E../node_modules/babylonjs/babylon.js.E._registerTransientComponents (babylon.js:1)
    at E../node_modules/babylonjs/babylon.js.E.render (babylon.js:1)

The error goes away if I do not create the Dynamic texture, IE commenting out this line:
var advancedTexture = GUI.AdvancedDynamicTexture.CreateFullscreenUI('ui', true, scene);

Edit: I assume I would need to use the BabylonJS version 4.0.0 as well? Still using 3.3.0

everything has to be on the same version: gui and bjs must be on the latest version

Gotcha… although I’m a bit hesitant to use an alpha build. How stable is the latest alpha (of babylonjs)?

We call them alpha not because of the quality but because of where we are in the dev cycle:

  • alpha: we add new features
  • beta: we document / fix potential issues / create demo
  • release: we package everything up

So you can blindly take the alpha version :slight_smile:
