    Hi there,

    I'm attempting to create a script (or xpresso if possible) to automatically reference target objects in the constraint tag.

    eg: I have 100 cubes and I want them to all to have a minimum distance clamp on each other. That is 10 000 relationships, too many to do by hand.

    I've looked through the official COFFEE documentation but cannot see anything related to this.

    Is there something I'm missing?

    Having a lot of objects keep a minimum distance to each other sounds more like a task for a particle system. Try doing it with TP ;-)

    Hey, thanks for the reply.

    Unfortunately I'm not sure that TP is way forward for what I'm trying to achieve.

    Ultimately, what I'm creating is a large curved surface with lots of screens arranged in a mosaic formation. There are however a few variables to consider.

    1. There are 6 different types of screen (size)

    2. I need to retain full creative control over the locations and densities of the screen arrangement. (Over the course of the structure, density will be different depending on location)

    3. There needs to be a minimum distance so the objects don't collide.

    I'm quite new to TP and probably don't fully understand the full potential or limitations but I don't think you can control the particles individually?

    Constraints therefore seem to be the right tool to use but I need to be able to modify the modes and distance parameters for many targets simultaneously.

    If there is a way to iterate through the target list of a tag in xpresso?

    Also does anyone know how to access constraint tag information parameters through COFFEE?

    Cheers

    Adam

    Unfortunatly it's not possible to iterate through description elements in COFFEE.

    The only thing you can do is to directly access the link fields if you know the number of them.
    For instance the first clamp link field has the ID 50001, the second 50011, the third 50021 and so on. You create a clamp constraint and add all the targets by calling CallButton(). The ID of the button is ID_CA_CONSTRAINT_TAG_CLAMP_ADD. Then you fill the link fields.
