Hello Paul, hello all !
i've got a question about a YsplineLength and a little expression (theoric)
I take the same exercice BUT, if i want to make a shutter in place of glaze ?
So, I will make the defaut segement (left segment) to the same y dimension as the simple shutter (call it Y defaut value)
Then, if our Railclone split in twice our full window in the "sequence" i think about scatter the simple shutter with a Mode "Count" and to obtain automatically the good count for that simple shutter, i think to use the "Ysplinelength"
I need the Yvalue from top segment >> Input1
YValue from the cross segment >> Input2
and also YValue from the bottom segment >> Input3
And soustract them to the YSplineLength then divide by 2 the result (because our "window" is split by the middle)
So i tried that :
Return
(YSplineLength - (input1+Input2+Input3))/2
;
so it should result a length that now i can divide by the shutter Yvalue to obtain... the count i need automatically ?
So, i take the YValue from my defaut segment in >> Input4
Return
((YSplineLength - (input1+Input2+Input3))/2)/Input4
;
But.
It don't work.. :'( (middle section didn't appear
so i have to place a Numeric fonction with random manually each window size... too bad...
What is wrong in my formula ?
Here is the shutter window
thx in advance, i'm pretty sure it's as always a little thing :'(

Hi,
Please take a look at the attached. I changed a couple of things.
First of all, the counter parameter of a Sequence node technically can't be controlled with expressions, I was actually surprised to see it working as well as it was in your example. Instead I've replaced those with a Geometry Switch Macro which is basically just a Selector node that can be toggled using 0 or 1.
Secondly, in your expression, you are dividing the height of the array by the Y Size of the Default segment to find the count. This would be fine if the sides were the same height but they are in fact a little larger to create the gaps between the louvres. If you instead wire the Y Size of the Left Default segment to Input 4 of the expression you should get the expected results.
I hope that helps,
Paul

Damned Thx !
LOL : "a couple of things"
It's not with my knowledge i can think about that...
And if it work as well this is probably because the pivots ;) i make it smart
I know that it could take time, but i'd love to have explanations on that variables and macros you're using.
Cheers!
