[Closed] Distribute array of objects along spline lengthInterp

Sep 29, 2017 6:26 am

Hi there
Maybe so simple and i missed sth so basic but how to disterbute array of objects along spline path the way like this:
The first one be on 0 and last on 1 and other distributed evenly.
For example for the array of 7 elements teapot the first teapot on 0 and the last teapot on 1 and the 4th teapot on .5


delete objects
spline =Arc radius:100 from:314 to:225 pie:off reverse:off 
convertToSplineShape spline
new_objAr = for i=1 to 7 collect (Teapot radius:15  pos:[i*15,-100,0])
   
--
for i=1 to new_objAr.count do (new_objAr[i].pos = lengthInterp spline 1 (i/(new_objAr.count) as float))

well your 1st one is 1/7 = 1 seventh…when logic tells you that it should be ZERO

so here’s my fix…I’m sure other mxs gurus can give much more elegant solution…but you get the gist with mine…

new_objAr = for i=1 to 7 collect (Teapot radius:15  pos:[i*15,-100,0])
maxcount = new_objAr.count - 1

--
for i=0 to maxcount do (new_objAr[i+1].pos = lengthInterp spline 1 (i/maxcount as float))

I tried each part of your code except i= 0 and new_objAr.count – 1 TOGETHER.

Thanks you for the quick reply
