"Unable to find specified agent to request permissions" error on modified [AV]object script (AVsitter2 open-source)

[AdminGirl]

I've been modifying the [AV]object script so that a prop can remain attached and keep animating an avatar even after teleporting to another region. I've managed to get the prop to stay attached and keep animating, but once I'm in a different region, I keep getting the error message "Unable to find specified agent to request permissions".

I'm pretty noob to both SL and scripting.. is this the right place to ask?

This is certainly the place to ask, but without seeing the script it's a bit difficult to diagnose the problem.

You can use the <> toolbar button in the edit window (next to the smiley) to paste your formatted code in messages here.

Thanks for letting me know Innula 🙂

I'm not sure I quite understand what the [AV]object script is supposed to do... don't temp attached objects remain attached normally through teleports? I thought only a logoff would remove them?

However, I glanced over the code and the first thing that jumps out at me is your use of llDetectedKey(0). That function only returns meaningful results when used in a few very specific events. From the wiki page:

Quote

llDetected* functions only work if called from within Detection events (collision, collision_start, collision_end, sensor, touch, touch_start, touch_end) or in functions called by Detection events. They will fail silently and return unusable values if called during other events.

So your error is probably occurring when you try to feed it into the llRequestPermissions function inside your listen and timer events. Perhaps you could replace that with llDetectedKey in those events with llGetOwner, since an object has to be owned by the avatar wearing it. And in the case of temp attach, ownership is transferred to the new target for the duration of the temp attachment's worn existence.

Thanks for your reply Fenix.

The [AV]object script is used so that when an object is touched, a menu appears. When a menu button is selected and if permission to animate is granted, a prop will attach to the avatar. The [AV]object script is for the prop, and two other scripts are dropped into the object that is touched.

I've seen it used in a cake object, and after touching it, an avatar is animated to eat the cake with props and even after teleporting away, the animation and attachment remains.

After changing the llDetectedKey(0) to llGetOwner, the error messages don't appear anymore (yay), but the attachment disappears after teleporting.

I'm being a bit slow today, having trouble fully comprehending the flow of the code. But there are a few thoughts that come to mind.

Your code has three instances of calling llDie and another three instances that call llDetatchFromAvatar. Either of these will potentially remove the temp attachment. So I would suggest you add some instrumentation code to see if any of those are being called when you teleport. Basically, stick a llOwnerSay("debug message") line immediately before each llDie and llDetatchFromAvatar function call. Give each one a unique message. This will help indicate which (if any) of these lines are being called when you teleport and narrow down where the problem is occurring.

Now if it turns out that none of the above are being called when you teleport, then the issue may be with the other two scripts you say are being added to the prop. You may need to examine them to make sure they're not calling their own llDie or llDetachFromAvatar.

Oh you genius, it worked!

It was the first llDetachFromAvatar function under run_time_permissions, so I replaced it with llAttachToAvatarTemp(prop_point) and now it stays attached wherever I go. Thank you so much!
