How can I tell if a path has been completed?

I have a Path3D/PathFollow3D and a cube assigned to that basically just runs in circles. So far so good. But how do I detect if the cube has completed the path successfully? My idea was to check for the progress_ratio in func _physics_process(delta) and trigger my action every time it hits 1.00 but that never seems to happen.
Setting it to 0.99 causes it to trigger my action multiple times so that is also not reliable.

Any ideas? 🙂

This might depend on how you're moving along a path although typically, the progress_ratio property indicates the distance along the path [0, 1]: https://docs.godotengine.org/en/stable/classes/class_pathfollow3d.html#class-pathfollow3d-property-progress-ratio.

As it is a float, you likely want to compare using is_equal_approx(1.0, ratio) (that's assuming you weren't doing so already).

You do mention it running in circles so perhaps you're also looping rather than reaching an endpoint? For that, you'll need to note a reasonable endpoint and use a similar comparison.

spaceyjase ok, I have tried

if(is_equal_approx(1.0, $Path3D/PathFollow3D.progress_ratio)): multiplier += 1 print("loop complete")

but that also did not trigger.
I was thinking about a scenario where I would loop a path 3x and then change to another path to loop 2x and then back again.

It's probably helpful to share your code at this point so others can see how you're moving along the path, along with its settings.
