Summary 0003029: attach(key )attached) event unrecognized
Description The basic attach() event handler is still unrecognized although attachments seem to be working.

// should at least say something like:
// [14:19] Object: Running attach event test. Should say av key.
// [14:20] Object: Attached: 7a41dd02-dac9-4d4a-a013-92ca1a65335b

default
{
    state_entry()
    {
        llSay(0, "Running attach event test. Should say av key.");
    }
    attach(key _attached)
    {
        llSay(0, "Attached: " + (string) _attached);
    }
}

 Because attachments have no persistent state in opensim, the handling is different.

 Does this mean there are no plans to implement the attach() event as handles in Second Life currently? If so, just need to know so we can work around.

 There are no immediate plans for compatibility. Scripts in OpenSim will have to account for the fact that script state and data is lost and scripts restart from the beginning on each attach.

 I wonder if just an on_rez() event with more primitive llGetAttached(ATTACH_RHAND) might cover it. Will test.

 The following work around tested successfully in ReactionGrid. Primitive, but gets the job done at least for event handling that normally would have happened when first wearing/attaching an item.

default
{
    state_entry()
    {
        llSay(0, "Work around for missing attach() event handler");
    }
    
    on_rez(integer _param)
    {
        if (llGetAttached() == ATTACH_RHAND)
        {
            llSay(0, "Attached to right hand.");
        }
    }
}

 I can only assume the reason attach(key attached) event handling is being omitted is because the 'attached' key is part of the attachment state. Still couldn't we call the attach() handler without that property? Most just use it to indicate an attachment has been worn or removed. It seems ignoring that requirement would be unnecessary, even against the OpenSim goals of SL compatibility.

 Since no one has posted any comments here since January, I thought I would throw my two cents in and say I would love to see the attach event implemented, mainly for reasons of compatibility and code portability. I am just hoping, with all of the changes and refactoring that have taken place since January, that maybe it has become more do-able. If not...well, all thing considered, we're still doing OK.

 We need ROBUST to do it. attach() goes hand in hand with proper attachment state handling, which we can't have until we have overwritable private assets, which ROBUST provides API and functionality for.Without that, attach() makes no sense.

 Attach works on 2c0c21d0a5fd89120d8be47cd959acd96b286fe3.
