Movable object along path

NWA — Mon, 15 May 2023 13:34:03 GMT

Hi all,

with your help in my post (here) I was able to write an object with Hotspots to rotate and to move components of an object.

Something new that I would like to try is to make components of that object movable along a predefined path. In my example (see screenshot below) I would like to move the armchair along the edge of the carpet from the top to the right side.

The “3D Kitchen” from the Archicad library has that exact functionality, but I was not able to understand how it works, let alone reproduce it for my simple 2D object.

Can anyone hint me to some pointers or commands on how to achieve this modification?

Many thanks in advance.

If they are the same object, and they do not need to go around a corner, you can use a fixed x/y coordinate while the other is linked to your dynamic hotspot?

There you go.

The trick is in the parameter script.

You have 2 parameters, chair position x and y that must have different constraints depending on the side of the carpet the chair is on. GLOB_MODPAR_NAME lets the script know when to change those constraints.

Thank you both very much!

I finally managed to complete the object with all its functions. 🙂
