set / get spatials from item

Hi all,

I try in vain to set "spatialy" of an Item in the OnEntry Trigger of Conveyor/ Basic Conveyor.
Found out till now that it´s not possible to change the value in tree. And similar what value is written "getnodenum(node(">spatial/spatialy",item));" it allways returns 0.

What I want to do is to set position of item (not only Shape offset) from center to one of the borders of Conveyor.
With Basic Conveyor I realized, by using kinematics, that items run to border while conveying. In tree "spatialy" of Item changes to 0. But it seems impossible to give this data to next Conveyor / Basic Conveyor!?

Attached a small Example model.
Can anybody give me a hint, how to solve this?

Greetings

Sebastian,

I would store the data you need on the next conveyor in labels on the item itself and set its position on the downstream conveyer according to these labels.
Be aware that this is only working for Basic Conveyors...the standard conveyor is too intelligent to allow you changing item positions while being on the conveyor.

Goos luck!

Hi Ralf,

thanks for your reply. Think storing data in a label isn´t the issue.
Just got problems with setting or getting the value on "spatialy" of Item.
It looks as if "setnodenum()" and "getnodenum()" doesn´t work in this case. Even "setloc()" doesn´t work. Similar for Conveyor and for Basic Conveyor. And I can´t find out why.

Sebastian,

once you added a kinematic to an item, you can't change its position manually anymore. You would need to make the position change in y-direction on the conveyor part of the kinematics (on the basic conveyor only. For the standard conveyor you just can't affect it).

Good Luck
