I need help to make a Vector List in Animation node.

What I tried you can have it in the link https://blend-exchange.com/b/w7OPLjo6 this work if I use Append list (done for 2d vector ) with vector list inside the loop and same thing doesn't work when I pass the vector list in to the loop a take vector to append from the list through get element node (you can see scheme in the file finished with 3.blnd in github ).

What did I do wrong?

  • $\begingroup$ Hi Kebab, i really love animation nodes and i would help you - if you would be more thankful, but you aren't. And you aren't willing to try things out yourself and additionally although Duarte wrote several times you shouldn't write in all caps you are still writing in all caps. You expect people who write you an answer that you even get a blend file presented all on a silver tablet so that you have nothing to do and nothing to try out. But that's not the way how you learn to deal with Blender. $\endgroup$

  • $\begingroup$ And you ask a lot of questions - but you only hit "accept answer" one single (!) time - that's why you aren't thankful in my eyes. And by the way: if you cannot read an image, you can click on it, it will be zoomed. $\endgroup$

  • $\begingroup$ and blend files should be provided here: blend-exchange.com and not on github, because your question gets a bit worthless if you decide to delete your blend file on github. thx. $\endgroup$

  • $\begingroup$ Hello mrs Chris.Reguarding your alligation of not being kind I think I add "Thanks" @ the end of my question ,Any way From today I will give Accept every time some one give some answer .Further more I didn't know that file should be added in blender site & not in Github .Finally as you noticed I eidted my writing in small letters ,My only intention of using Caps was underling the title of the question.Anyway Please help with your knowledge, Because I tried a lot befor asking question here ,it's not true that I don't do anything my self. $\endgroup$

First create your base object (cylinder with icosphere as one object). Important is here that the origin point of the object is at the center (0,0) as here in my picture:

enter image description here

Then create a plane, add a geometry nodes modifier with this node setup:

enter image description here

result:

enter image description here

enter image description here

Explanation:

If you want to "debug" or understand a geometry nodes setup, it is always a good idea to mute nodes to see the difference or what's happening.

So here i muted these nodes:

enter image description here

and as you can see the objects will be just stacked on each other on the z axis by the unmuted nodes.

These four nodes here:

enter image description here

are responsible for the z-rotation of the object. Depending on the index they will be just multiplied with a certain value. Of course you can change this value if you want to have different angles. But keep in mind that you have to change other frame dependent values too so that the animation works correct again.

enter image description here

These four nodes make the instances visible after a certain time. So they are responsible for one part of the animation.

The last nodes here:

enter image description here

...are responsible for the animation of the "one" cylinder which is moving all around. It is moved on the z axis and rotated on the z axis as well. To be honest, i did not calculate the multiply-values but i just eye-balled it so that the animation looks ok. You can use calculated values if you want to - i was too lazy for that.

  • $\begingroup$ the first node setup (2nd image) is total clear. Just click on it and it will be zoomed, but i uploaded the blend file anyway. $\endgroup$
