copy different pieces to different point issue

[Gabriel_Wolf]

Hello,

Can you help me a little bit? I have an obj file about tetris pieces. I would like to copy randomly one piece to a random point.

What is wrong with my setup?

Thank you

I can see a couple of things wrong with your setup. Not sure why you have a for each there that you aren't using that is not why isn't working but not needed. Also, your objects that you want to copy they all should be at {0,0,0}. You are using a deprecated technique.
I think it will be better if you post .hip

Or have a look at, you are missing some fundamentals

Thank you. I will check the video. And I attached my hip file

Hello,

you didn't attach Tetris.obj. This is an example how you can achieve what you want.

First, thank you for your help. And I'm sorry but my hip file was a mess. And this time I attached the tetris obj. The main idea is to copy random pieces of the tetris obj to the points of the cube using the class attribute.

I've guessed that. What's wrong with my first example? In this new example file I just added transform sop to move pieces to the origin.

It is working. Thank you. Let me ask don't you want to mentoring a couple hours? I pay for it of course. Maybe we could make a skype session or something. 

It is a really good thing that you showed me how to do that. But my main goal is understand the workflow. And there are some things I don't really undestand in your setup. Mainly the VEX.  And my main issue is with the vex. For example I posted another question here where I asked how to add a custom velocity for only particles which are under age 1? And somebody wrote the same solution I've already knew. But I can't write it with vex.

I think my level not enough to be a mentor. This forum is the golden mine of knowledge and you can get it for free just should search carefully.

Workflow of this example is pretty simple. We take points and set randomly attribute i@id,  whose value is fit from 0 to quantity of pieces in .obj file. This attribute say “blast2” node if i@class equal to i@id then delete all but not this one.  For-loop iterate by points, one point per iteration which number gives us node “meta” from detail attribute i@iteration with expression.

 detail("../meta", iteration, 0)

At each iteration “blast2” with expression

`@class=`point("../OUT_pts", detail("../meta", iteration, 0), "id", 0)`

takes a point, finds i@id value of the point with number of iteration, and deletes pieces with i@class not equal i@id. Copy to points sop in for-each loop copies that piece to the point which is iterating at this moment.

Thank you for the explanation.
