LSL Protocol/Restrained Life Relay/delay

This is a discussion page for adding support of delays in the execution of relay commands.

!delay

Not implemented yet

Description

meta command to pass a delay (in seconds) the relay has to wait before executing subsequent commands from the device.

Background

Most of world objects just lock you in on some fixed piece of furniture, and thus can easily ensure you will eventually be released of every restriction, as it will do it at the time you are allowed to stand up. Other devices have other ways to ensure you're eventually released: for instance, zone controllers use a sensor and send a "!release" as soon as you exit the sensed zone.

In both case, the device is still nearby from the beginning to the end. What about if you want to restrict someone in some way, but don't want to prevent them from leaving? It is currently impossible to do it while ensuring a timely release (or you have to rely on the fact that the relay verifies the device is still nearby and active).

Here I propose to add another way to ensure the release of restrictions, by delaying of some fixed time the execution of a bunch of relay commands (hopefully including a !release).

Syntax

!delay/(integer)

(integer) is the amount of time, in seconds, you have to wait before executing subsequent commands.

Other parameters after a second "/" should be ignored, as they could be used for a future extension.

Discussion

I still don't know if !delay should be applied on every subsequent command from the device, or only the ones of the bench of commands the !delay belongs to, thus allowing to affect the target while some commands are still pending.--Satomi Ahn 17:20, 21 March 2009 (UTC)

I think we need a way to modify delayed commands that have already been sent. --Maike Short 08:39, 22 March 2009 (UTC)

LSL http server or llEmail may be a better way to keep contact between the world object and the relay if the agent leaves the llShout area. But I have not look at that in detail, yet. --Maike Short 08:39, 22 March 2009 (UTC)

I haven't used llEmail but I heard it wasn't that reliable. Is it?

And what about http server? I see you commented the page, have you experimented with it? If the whole relay protocol could use http, then this "!delay" thing becomes useless (the capturing device could run a timer instead of the relay). But then, wouldn't we need a metacommand for requesting the URL? --Satomi Ahn 12:01, 31 March 2009 (UTC)

Other big issue: the URL will be disabled when going to another region, which kills the purpose of using http instead of chat (in our case)... unless the relay polls the capturing device, instead of the contrary.

Another issue, maybe, could also be the per-parcel URL limit (equal to the prim limit). --Satomi Ahn 12:11, 31 March 2009 (UTC)
