I’m working on a game right now, and life would be so much simpler if I could emit a signal when a PathFollow3D crosses the progress mark of 1.0 and resets. This would signify the end of a stage, and I could then use it to pop up the end-of-level overlay.
Kind of like the finished signal for a sound.
Unfortunately, I can’t find any information on this.
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_ratiovalue.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 signalTried that, didn’t work. Progress_ratio is never greater than 1.0.
isn’t that why he used >= so when it’s equal to 1.0 it’s done
It may never be exactly equal to 1.0, as it’s adjusted discretely by a velocity, and it’s a floating point. If we were talking about integers you might be correct.
For the moment, I’m working around the apparent absence of such a signal by putting a collision shape at the end of the path. But, it really feels like it should be a thing.
It’s not a signal, but it is a quick check. In 2d there is a (in godot 4) progress_ratio that scales from 0 to 1. So a quick
If $pathfollow.progress_ratio==1: #I’m at the end of path end_of_level()
This is what I did in my game.
I don’t know the lemmy markup code for a code block so sorry for bad formatting
