how to get two or more point coordinate on spline at the same time

[ZeBoxx2]

have a peek at pathInterp and lengthInterp; not sure what you mean by "at the same time", though..


Shape Common Properties, Operators, and MethodspathInterp <shape> [ <curve_num> ] <parameter>

Return a point3 coordinate on the numbered curve (defaults to 1) corresponding to the parameter value (0.0 to 1.0) that matches the 3ds Max Path controller percentage (vertex-based) interpolation.



lengthInterp <shape> [ <curve_num> ] <parameter> [ steps:<integer> ]

Return a point3 coordinate on the numbered curve (defaults to 1) corresponding to the parameter value (0.0 to 1.0) that is that fraction along the curve's total length.

Hi, ZeBoxx2

The script only get one point coordinate ,If i want to get two point coordinate,How to do
I would like a long time, but no results.

if $ != undefined and subobjectlevel == 1 do
(
UpdateShape $
spline_int = #(0)

for i=1 to numsplines $ do
(
test = getKnotSelection $ i
if test[1] != undefined then spline_int = #(i)
)
knot_index_int = getKnotSelection $ spline_int[1]
knot_point = getKnotPoint $ spline_int[1] knot_index_int[1]
)

err.. not entirely sure what your code is supposed to do - but I'm going to guess you want an array of the positions of the currently selected knots?


fn getSelectedKnots = (
local mySelectedKnotsPositions = #()
if (((getCurrentSelection()).count == 1) AND (subObjectLevel == 1)) do (
for i = 1 to (numSplines $) do (
for knotIndex in (getKnotSelection $ i) do (
append mySelectedKnotsPositions (getKnotPoint $ i knotIndex)
)
)
)
mySelectedKnotsPositions
)
getSelectedKnots()

I mean is get coordinate of the currently selected knots,
your fn back results:

#([-64.2512,-3.77987e-006,86.4734], [-61.3527,-4.43449e-007,10.1449])

I want to get, like this:

[-64.2512,-3.77987e-006,86.4734]
[-61.3527,-4.43449e-007,10.1449]
--------------------------------------------------------
I modify that script but sometimes it can't correctly run
(
if $ != undefined and subobjectlevel == 1 do
(
UpdateShape $
spline_int = #(0)

for i=1 to numsplines $ do
(
test = getKnotSelection $ i
if test[1] != undefined then spline_int = #(i)
)
knot_index_int = getKnotSelection $ spline_int[1]
knot_point = getKnotPoint $ spline_int[1] knot_index_int[1]
)
)

(
if $ != undefined and subobjectlevel == 1 do
(
UpdateShape $
spline_int2 = #(0)

for k=1 to numsplines $ do
(
test2 = getKnotSelection $ k
if test2[2] != undefined then spline_int2 = #(k)
)
knot_index_int2 = getKnotSelection $ spline_int2[1]
knot_point2 = getKnotPoint $ spline_int2[1] knot_index_int2[2]
)
)

Hi ZeBoxx2

Thank you very much! I understand !
Use your code


mySelectedKnotsPositions = #()
if (((getCurrentSelection()).count == 1) AND (subObjectLevel == 1)) do (
for i = 1 to (numSplines $) do (
for knotIndex in (getKnotSelection $ i) do (
append mySelectedKnotsPositions (getKnotPoint $ i knotIndex)
)
)
)
mySelectedKnotsPositions
v1 = mySelectedKnotsPositions[1]
v2 = mySelectedKnotsPositions[2]


Thank you once again

[ZeBoxx2]

Yep - correct :)

Good luck with your script!
