What makes a item shout :Not permitted to copy that inventory.

This happen tonite while someone was looking at my beds.
Speedwell's MLP Sexbed, #1 shouts: Not permitted to copy that inventory.

I never had that happen before. And i dont know why the bed would feel the need to shout anything

A wild guess, but have you added any no-copy animations to the bed?

Shouts of that type are usually script run-time errors.

That shouting is scripted by the creator of the item. It's sort of like a car alarm, intended to make it obvious to all around that the person is trying to do something inappropriate with the item. In this case, I would guess that the animations in that bed are not allowed to be copied to your inventory. Most nice animations are no-copy. Why would the maker of a scripted bed want to allow you to freely use the animations from their product in your own product? Most would consider you copying their animations to be an extreme misuse of their product. So by scripting in a shout when the script detects an attempt to remove a no-copy script, they 'set off an alarm', warning the user that this is not an allowed operation. While they could just silently allow the removal to fail, making the thing shout could apply peer pressure from others to get you to stop trying to do that.

Sorry Ceera, but I don't think that's it.. a script can't stop you removing no-copy inventory from an object, although the SL permissions system will still ensure you can't copy it. It could technically shout and complain, but that isn't that effective, especially since you could simply remove the shouty script from the object first.

From the sound of it, it's an object he made himself anyway - MLP is MultiLovePose, an open source animation system.

However there are some circumstances where it's actually programmed into SL that an object will shout. The classic example is for objects which allow the general public to insert things into them (such as notecard mailboxes) - if you try to drop in a script, the recieving object will shout "Not permitted to edit this!" and ignore the attempt. Likewise, trying to have a scripted object link itself to something you don't own or have modify permission on makes it shout.

As far as I'm aware the only thing which causes shouting about "copying inventory" is when a script tries to give something in its inventory to another object without copy permission, and this is fairly often done when setting up poseballs, thus my question about animations..

I know of one situation that causes exactly this, and as Yumi said it's something built into the infrastructure of SL, not something caused by a script.

While making adjustments to an object which was owned and placed in-world by someone else and shared with a group so that it could be moved and edited by myself and other group members, the exact same thing happened when I tried to drag either a notecard or a script directly from the object to my inventory. The notecards and scripts were full perms, and I was free to open and edit the notecards (since the object was shared), but trying to drag them resulted in the shouted warning.

Now, when an object and all its contents has restrictive perms anyway, it seems like one is simply prevented from copying the contents; but in the case of items with full perm open-source contents, the shouted warning happens and the copy still fails.

I can't test right now to see if that's always the case, even for items like your bed which are probably NOT shared and NOT intended to be editable by anyone other than yourself, but your story sure makes it sound that way. In any case, I'd say it was somebody either trying to drag a notecard over or, maybe just as likely, someone poking in the contents who had their mouse slip in such a way that SL interpreted it as an "attempted drag and drop".

Yes it must be something built in because I gave my alt something once and when she opened it and tried to drag something out the object shouted at her. I'm pretty sure I didn't make any kind of script.

Yes the bed was made by me and all items in the bed are not copiable. That is why I wanted to know what caused the uhh "alarm" to go off
