RPG Inventory system

I’m stuck at around 10:40, he says in the video that you can migrate the UI into your own UI, but I’m not really sure how you do this?

This whole video is super outdated and really hard to follow.

Could anyone help me by putting some instructions down so I could follow them and migrate this into my project successfully?

Thank you.

When he says ‘migrate’ I think he probably means ‘put these same nodes into your widget’, no?

Yeah I’ve put the nodes into controller…
