Hi,

if possible can you please give some more information about the individual issues?

disappear material does not work

Can you please elaborate what "does not work" means and where it happens?

The sound works strangely in the main menu

Can you please share a screenshot of how the sound is triggered in the logic nodes? It sounds as if it is restarted as long as you hover over the buttons.

I also noticed that there is an audio related exeption when starting the level:

I'm not sure yet what causes it. If this exeption also happens on Krom it would be great if you could share it.

save and load system does not work

Which nodes are you using for that? The Write JSON node for example is only implemented on Krom currently, but using Write Storage should work.

sorry it is my mistake I mean visibility node dose not work but I think It dose not work because read and wright storage

I am using read and Write storage

So the problem with the sound is indeed that the OnCanvasElement node output is activated on each frame that the mouse is over the element. The problem with the way Zui works (it's an immediate mode UI) is that it is not straightforward to find out if an element is hovered for the first time in a row, at least I don't know a good solution. If the element ID input would be static (no input socket, just a text field), we could implement this very easily in the node, but when it can potentially change every frame it gets tricky.

So I guess the best would be to check this manually, something like this could work (untested!):

It's probably best to use a node group here to be able to reuse the nodes for different buttons.

Can you also please share a screenshot of how you are using the read/write storage nodes? They work for me on html5. What does not work with them? Is it the read or the write? The NaN (not a number) when loading the values for the first time when no storage file exists (that's probably because you haven't set a default value and null is returned)?
