If you have an endpoint on the curve and the curve itself, and you need to get the neighboring point, you can check the point's ID on the curve using M_Curve:PointID(point).
If PointID == 0, then the neighboring point will have the ID PointID + 1. If PointID ~= 0, then the neighboring point will have the ID PointID - 1.

KuzKuz wrote: ↑Tue Aug 13, 2024 11:03 am Alright, I will write the code that returns the neighboring point on the curve. However, I recommend that you study other people's scripts.
You don't need to read 4740 lines of code to understand how curves and points work.
Use the search function to find methods related to curves and study how they are used.
That's how I learned.

Thank you!
Yea, That is my method as well, but in this case I'm looking for a more spicific function that support's all conditions, not only cases you implemented in that code, so yes, I need help from you to write a fuction that covers all cases.
For example when point have more than one curve.

The problem is when I iterate over Shape > Points, the point order goes in the wrong direction:
