How to click a button of a node inside the network of an asset?

[magneto]

Hi,

I am making an asset where I want to click a button of a node inside the subnet of the asset. I know how to do these for asset parameters but not sure how to do it for a node inside an asset.

Any ideas?

Thanks

RMB click button-> Expressions -> edit expression? Is this what you are looking for?

[magneto]

Thanks, no I mean something similar to this:

kwargs['node'].hdaModule().setHeight(kwargs)

where you use a callback script to trigger a button click if the user clicks a button in your asset.

But I want to click the button of a node inside the subnet like:

kwargs['node'].nodes('/uvproject1/initialize').pressButton()

You'll probably need to make the node inside the asset editable and then use this:

Thanks Christian. How do you make the node editable? It's an instance of UVProject SOP. Also I don't know how to access that parameter as it's deep inside the network not at the asset level.

He means in the Type Properties window under Basic just put the uvproject node in the list of "Editable Nodes"

Thanks ikarus, I didn't know of that feature.

I don't think the node has to be editable in order to trigger the click event on the button.

You can also promote buttons from inner nodes to the asset's properties and let users click inner node buttons.

Thanks hopbin, I will promote it to the asset level, hide and trigger the click in the callback script, because I want to press it anytime they change some numeric values.

But if anyone knows how to access a parameter in the subnet from a callback script without promoting it to the asset level, that would be great.

I'm not sure you have to promote it in order to press it.

Try something like this, as a Python callback.

kwargs['node'].node('inner_node_name').parm('button_name').pressButton()

That should work.
