DEM Relay HUD
OK, so this page is massively out of date - I'm starting to fix it
((current release of the Relay HUD is 200f))
The DEM Relay HUD is an implementation of a multi-object, multi-restriction relay for the Restrained Love viewer (RLV) in Second Life™. In addition to providing the interface between in-world furniture/toys, it implements some extensions to the RLV specs that allow for identification of WHO is operating a device trying to access the Relay and functions to provide vision restrictions without another attachment/hud. Note that these vision restrictions are becoming less necessary as RLVa, at least, has added new functionality (particularly the @setoverlay capability). The HUD implements some, but not all, of the features of the Open Relay Group. These extensions and scripts are released under the following license:
The Relay HUD is released under a modified "CopyLeft" license. The short form without legalese.
This code is provided AS-IS, OPEN-SOURCE and holds NO WARRANTY of accuracy, completeness or performance. It may be distributed in its full source code with this header and disclaimer and is not to be sold without permission. Optionally it may be distributed in a 'no mod' form within Second Life™ PROVIDED that either a link to the source IS provided (ie. this page or a .zip or .rar) within the object the code is contained AND/OR a off-world contact point (ie. email) that the source code may be requested from. This somewhat unusual (no-mod) distribution is allowed to maintain the integrity and reliability of the creator reference of in-world objects (scripts). Changes and improvement to this code must be shared with the community so that we ALL benefit.
Once based on Maike Short's 1030b relay, with thanks to Tahni Tarantal, RL Ansome, Nihal Quan and everyone else who helped with the shakedown and development of this device. Transitive thanks to everyone that has gone before on the development of the Restrained Life Relay, including (but not limited to) Felis Darwin, Nano Siemens, Azoth Amat, Gregor Mougin, Cerdita Piek, Satomi Ahn, Marissa Mistwallow, Chorazin Allen, and Marine Kelley.
The relay has changed a lot since it started as Maike's 1030b. Indeed it might now have changed beyond all recognition; it's been torn apart and rebuilt multiple times - there are still functions that look like the original, but they are few and far between. So don't blame Maike for any issues.
Major and mega thanks to Maike Short for her (all too brief) guidance and inspiration as keeper of the Relay Standards. We all wish you were still here, we won't forget you, ever. I really owe Maike and, also Satomi, a huge debt for everything, the original relay as well as suggestions for extensions.
A note about the script; I do all of my scripting using lslForge which has an import function which make it easy to share constants and commonly used functions. I've tried to minimize use of such functions, but I do use a couple of scripts that are not provided here as they contain script elements that I prefer not to share. The only one that really needs a replacement is the one that performs all the menu functions. There is liberal use of constants that are easily replaced with any set of unique numbers.
These are the pre-processed files; the post-processed ones are not something you want to see.
In-world (no mod) copies of this relay may be picked up for free at DEM Store🖈 or email to Chloe1982.Constantine@gmail.com for source.
Design Points
THIS PART IS MASSIVELY OUT OF DATE We went into the design of the tkPBA with the intention of making it as flexible as possible in its handling of multiple objects. Originally we looked at the single script concept but quickly discarded this as being rather unwieldy and subject to the whims of LSL to its use of memory. With the all in one design, you can't reliably check on memory utilization, excessive garbage collection with list management and other quirks of LSL. It also left the script more vulnerable to the unexpected stack/heap overflow if you didn't put a limit to the number of devices it would control. Therefore, we split the relay into three parts -
- - the DPU (Dominant Processing Unit) handling all the 'global' tasks of the relay (listens, mode (off/ask/auto/hardcore), and implementation of the !who and !vision commands.
- - the SPU (Slave Processing Unit) handling 'object specific' tasks (what object and it's restrictions are in place).
- - the GPU (Graphics Processing Unit)) the 'bare metal' interface for the !vision command.
With the advent of llSetLinkPrimitiveParamsFast we no longer needed the GPU to be in the actual GPU prim; for reasons of efficiency (and so that I no longer had to keep flipping the PBA to edit the back of it) we've merged the GPU and DPU scripts.
Further, we took the actual architecture of the relay down to the 'prim' level. Since we have made this a HUD ONLY device (a. can't drop scripts in 'no mod' items that may already have their own touch events, b. not enough body attachment points as it is, c. keep it and it's status and control where you can get it at easily), we could divide the scripts among different prims to let them do part of the work.
- - the DPU goes in the root, the SPU's go in separate prims (one per # of devices you want to control), the GPU lurks on the back of the root prim and gets prim modification to affect the vision of the user.
- - the SPU keeps the UUID of the object currently controlling it in it's description field and the UUID of the last AV that used it stored either in the description or internally depending on whether or not giving control to the specified object is still pending. The DPU, instead of having to pass link messages back and forth, or keep updating an internal list, can find the current state of the object simply by reaching over with llGetObjectDetails(SPUn link number), [OBJECT_DESC]) and get the UUID's of the object/operator or if NULL_KEY see that the SPU is free to use.
- - the GPU is a single tiny prim that is glued to the back of the tkPBA that can be manipulated in size, color, transparency, texture, etc... to affect the vision of the victim.
There is, however, with the advent of the tkPBA 110r and later, a big change in philosophy with respect to the relay. The tkPBA has functions beyond those of just the relay (e.g., the LOCKER and other functionality), the details of which are not germane to the discussion of a relay. Yet we're committed to making the relay publicly available, including the scripts. Our solution is to provide the scripts for the DPU/GPU and the SPU; these are all the scripts needed to create an embedded relay. What is missing from them is the controlling script, what we call the supervisor, but its only purpose is to set the state of the relay. Note, you won't see anything about safeword either, the reason is that safeword is not part of the relay spec, other than a recommended good idea! In our case, the supervisor handles safeword processing and the relay simply responds as ordered.
Logo's & Signage
Think Kink has developed a logo to brand our products showing them RLV compatibility that eliminates the SL "Eye in Hand" that has some restrictive usage rights. With the publication of these scripts, we are opening them for use by the community as long as attribution is given to Think Kink. Email Ilana.Debevec@gmail.com for a TGA of the logo. --Ilana Debevec 19:52, 27 February 2009 (UTC)
tlRLV logo
In reality, you will get a pack of logos; we use different colors of insert to represent state; the one shown above is for a relay that is on and in ASK mode, we also support Off, Play, Auto, Hardcore (with or without safeword) and remotely controlled (with or without safeword). --Chloe1982 Constantine 09:57, 4 May 2012 (PDT)
tkPBA Command Extensions
A better place to look at definitions of !x-who and !x-vision is the Open Relay Group pages [1] which Think Kink will continue to support and add a growing number of x-tensions to the PBA.
!who also !x-who
- Description
- !who is implemented as a meta command to pass the UUID of WHO is trying to operate your relay, not just WHAT device and the OWNER of the device (more often than not, WHO's the operator and WHO's the owner are NOT the same avatar).
- !x-who is a synonym for !who and was created when the future of !who was put in doubt
- Background
- Since the Restrained Life viewer was introduced to the grid, almost from day one we have people coming to our store wanting a way to know WHO is trying to control their relay, it's almost become a mantra "I don't care WHAT it is, I want to know WHO it is!". This gives the tkPBA the ability to give some useful information on the actions of someone that is attempting to 'use' your relay to help you make informed decisions when your relay is in ASK mode.
- Syntax
-
- !who/(key)
- where (key) is the UUID of the AV that you wish to present to the relay.
- !who/(key)
- Implementation
- THINK KINK is implementing this in our devices with the following few caveats -
- - !who must be the FIRST entry of a RL Command string that will RESTRICT or DIRECTLY EFFECT someone. So, anything that will (for example) 'lock', 'force', 'deafen', 'mute', etc somone will get a !who
- - !who would not be required for things like !release, or anything that UNRESTRICTS someone.
- - !who is not additive, only the last !who is tracked for any given SPU (object).
- - !who/NULL_KEY is moot, if you don't know !who, don't sent it.
- - If no !who is sent, normal object verification rules apply
- - NOTE for builders.
- On a 'self activated' device (such as an area effect device that, let's say, restricts chat or tp or flying), the !who should be the UUID of the VICTIM!. This makes possible the ASK text such as "You have activated Crafty Avatar's Area of Doom and it is attempting to control your relay, ALLOW/DENY?".
- A TRAP device however would generally have someone that 'set' the device (in the case of THINK KINK devices, we have an AUTOLOCK setting) and if the device knows that, it should send the UUID of the PERSON THAT SET THE TRAP ... ie. "Crafty Avatar wants to control your relay using their Dasterdly Device, ALLOW/DENY?"
- - NOTE for builders.
- Further Points of Implementation
- The ASK message should change if a !who command comes in, so instead of "Dastardly Device owned by Random Avatar wants to control your relay, ALLOW/DENY?"
- - the message becomes "Crafty Avatar wants to control your relay using Random Avatar's Dastardly Device, ALLOW/DENY?"
- - if the owner and the operator are the same, then a more succinct message could be "Crafty Avatar wants to control your relay using their Dasterdly Device, ALLOW/DENY?"
- - if a !who is present, then should the victim DENY the request, an IM should go back to the 'clicker' "Sitting Duck has denied your attempt to control their relay".

!x-vision
- Description
- meta command to control what the victim can see while under restraint. This will allow a full range of vision control of the victim. Full blindness, partial, color, textures, etc..
- Implementation
- using a small microprim that hides on the back of our RelayHUD, we can expand and texture this to control the sight of the victim. Put them in a dark cell, they go blind. Or in a forcefield change the color, make it partially transparant, put up a texture, etc. We are/will also be using this as a "MouseLook" enforcer to punish a victim when they won't stay in mouselook (get out of mouselook, go totally blind). Currently being implemented in devices from THINK KINK.
- Syntax
- !x-vision/(color)/(alpha)/(texture)/(repeats)/(offsets)/(rotation)
- (color) = color for the HUD covering prim in RGB format <r'g'b> 0-255 or 0-1.0(NOTE: the ' is the seperator instead of , to avoid parsing issues with the rest of the RLV command string. Second note: you cannot mix number ranges either all are in the range 0 to 1.0 or all are in the range 0 to 255)
- (alpha) = % transparent to make the HUD prim cover (in alpha format 0.0-1.0 or as a percentage 0 to 100)
- (texture) = UUID for a texture to apply to the prim
- (repeats) = x/y repeats for the texture, same format as the texture tab on an prim 1.0'1.0
- (offsets) = x/y offsets for the texture, same format as the texture tab on an prim 0.0'0.0
- (rotation) = rotation of the texture
- SPECIAL ENTRY, any of the parameters can be replaced with "*" for 'do not change existing value'
- NOTE: the 'default' value of the HUD prim is 100% transparent, white, TEXTURE_BLANK. ie. !x-vision/0.0/<255'255'255>/TEXTURE_BLANK/1.0'1.0/0.0'0.0
- if all you want to do is 'blind' someone, then !x-vision/<0'0'0>/1.0/*/*/*/*
- Examples
- Total blackout "!x-vision/<0'0'0>/1.0/TEXTURE_BLANK/1.0'1.0/0.0'0.0/0.0
- Light fog "!x-vision/<128'128'128>/0.5/TEXTURE_BLANK/1.0'1.0/0.0'0.0/0.0"
- In a plywood box no matter where they look "!x-vision/<255'255'255>/1.0/TEXTURE_PLYWOOD/1.0'1.0/0.0'0.0"
- Compatibility
- since this is a metacommand, relays that don't support this should ignore it
--Ilana Debevec 18:29, 5 March 2009 (UTC)
!x-vision/clear
- Description
- complimentary command to !x-vision. Reset and remove all !x-vision restrictions.
- Syntax
- !x-vision/clear
- Compatibility
- same as !x-vision, if the relay can't, then don't

The SPU
The SPU (Slave Processing Unit) is assigned to an in-world object as it attempts to control the PBA. Each SPU is located in a seperate prim that, in the tkPBA is a single 'pip' inside the loop of the padlock that is the tkPBA HUD. When a SPU is free, the pip is black, when it is actively being controlled by an object, it turns green. When an object is assigned to the SPU but the tkPBA is in 'ASK' mode, the pip turns yellow until permission is granted (green) or denied (black and freed). The description field of the prim holds the UUID of the object currently controlling the SPU and the UUID of the last Avatar to send it a command (if available).
The SPU maintains all the restrictions of the object on the wearer, and generally the 'dirty work' of the relay function.
