There isn’t a signal because PathFollow3D doesn’t do anything on its own to move a Node. It just finds a point on the parent Path3D based on it’s progress/progress_ratio value.

I would suggest wherever you are updating the PathFollow3D’s progress, add a check for:

if path_follow.progress_ratio >= 1.0:
    # do something here, like emit a custom signal

I don’t think it has anything to do with “politics”. Blockchain / crypto is an area mostly focused on hype and marketing. So it’s not surprising that their “hackathons” have little to no substance.

I would say to give yourself the opportunity to have some fun with it. Maybe that could take the form of trying to apply what you know into some fun little project. Think about whatever you just studied and try to imagine what you could do with that knowledge. Don’t worry about constantly making progress. You will learn a lot just from picking a little project and trying to solve all the little problems you run into.

I know some people with privacy concerns will go out of their way to avoid any “smart” devices that communicate over WiFi. If you stick with Z-Wave/ZigBee/Matter, you don’t have to worry about any sort of external communications. I mean, even with WiFi devices you can isolate them by making a separate local-only network, but that’s a pain.

My friend and I recently released this short, sad unity game. Now I’m in-between projects and just making little prototypes for fun. This one’s an Earthbound-style RPG menu.
