Points of Segment

[MehdiZangenehBar]

We can get a segment of the shape using
M_Shape:GetEdge(edgeID, curveID, segID)
We can also get one of the points on the curve using:
M_Point:GetEndpointEdge(curveID, segID)
My question is how we can get second point?
In other word, any function to get two points that made a shape segment?

[KuzKuz]

Each point on the curve has its own ID, which is different from the ID of a point in the mesh.
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.

Thanks!
I'm little confused,
Is it possible for you to write it like a functions?

Try taking a look at how my script MR Curve Tool works.
There's a lot of code related to points and curves.
If you can't figure it out, I will write the function you need.

Yes! please do it!
it is very hard for me to read 4740 lines of code from someone else to undrstand which is which.

[KuzKuz]

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.

Please take a look at my other topic to undrstand why I need that function: viewtopic.php?t=37310
The problem is when I iterate over Shape > Points, the point order goes in the wrong direction:

Can you describe in detail what this function should do? What is the final result you want to achieve? As I understand it, simply accessing the neighboring point won't be enough for you? Please clarify what you mean by "covers all cases"?

If you just need to change the direction in your code:

MZ_Test_Script.counter = nil

function MZ_Test_Script:GetPointsTable(moho)
    local doc = moho.document
