Transcript for Thursday May 31, 2012
| [16:01] | Sandry Logan | horatio come sit | 
| [16:01] | Lorca Linden | hey all | 
| [16:02] | Falcon Linden | so please report if that happens again and include the time and region | 
| [16:02] | Rex Cronon | hi lorca | 
| [16:02] | TheBlack Box | heya | 
| [16:02] | Lorca Linden | so not too much officially on the agenda for this week | 
| [16:02] | Lorca Linden | my main announcements are : | 
| [16:02] | Lorca Linden | 1) we did a server code roll this morning that looks pretty stable so far | 
| [16:03] | Lorca Linden | that means that 2) we will be moving over the next bunch of about 20 resident regions to the pathfinding channel tomorrow | 
| [16:03] | Dahlia Trimble | you rolled to agni? | 
| [16:03] | Lorca Linden | we did | 
| [16:03] | Dahlia Trimble | oh maybe my robots are fixed then | 
| [16:03] | Lorca Linden | this morning | 
| [16:03] | Lorca Linden | my other announcement is that we have decided to impliment automatic transitioning into the edit / unfrozen mode for pathfinding | 
| [16:04] | Lorca Linden | that is the last major feature planned before release | 
| [16:04] | TheBlack Box | are PF-sims still all in debug-mode ? after Lorca turned Pathtest4 to non-debug mode it was offline all week | 
| [16:04] | Lorca Linden | we believe that will simplify the builder workflow, esp on the mainland since people will not have access to the estate manager tools for pathfinding | 
| [16:04] | M√¶stro Linden | the non-debug build had a crasher | 
| [16:04] | M√¶stro Linden | well, any region would crash | 
| [16:04] | M√¶stro Linden | so that's why pathtest4 was offline | 
| [16:04] | M√¶stro Linden | because it was crashed :) | 
| [16:04] | Nal | automatic transitioning into the edit / unfrozen mode? | 
| [16:05] | TheBlack Box | :) i feel guilty | 
| [16:05] | Lorca Linden | that is correct, nalates | 
| [16:05] | Motor Loon | automatic transitioning into the edit / unfrozen mode? | 
| [16:05] | Jonathan Yap | Are you asking what that is all about? | 
| [16:05] | Lorca Linden | we will detect when a resident takes an action that could change the navmesh | 
| [16:05] | Lorca Linden | and automatically transition them into edit / unfrozen mode | 
| [16:05] | Falcon Linden | All we know so far is that you won't need to explicitly "unfreeze" in order to modify navmeshy objects | 
| [16:06] | Motor Loon | aha | 
| [16:06] | M√¶stro Linden | Falcon, that will only apply to viewer actions, right? | 
| [16:06] | Lorca Linden | you will be able to manually trigger a nav-mesh regen with the pathfinding UI tools, and one will happen automatically after a set amount of time with no nav-mesh changing action. The time window is TBD | 
| [16:06] | Falcon Linden | maestro: correct | 
| [16:06] | M√¶stro Linden | as in, if my LSL script tries to change the shape of a navmeshy object, it'll still fail | 
| [16:06] | M√¶stro Linden | when i'm frozen, at least | 
| [16:06] | Falcon Linden | oh, actually, now that I think about it, we know even a little less | 
| [16:06] | Falcon Linden | We're going to punt the rest of the conversation on modes until next user group | 
| [16:06] | Falcon Linden | Suffice it to say, we're working on making it less invasive | 
| [16:07] | Motor Loon | alrighty then | 
| [16:07] | Lorca Linden | we are still hashing out some of the details so I agree with falcon that now is not the time to get into the weeds on the automatic build mode transition | 
| [16:07] | Nal | So, any builder working in an area, say on a house, will be able to affect Navmesh? | 
| [16:07] | Dahlia Trimble | just checked my robot on agni, seems to be working properly now | 
| [16:07] | Falcon Linden | Nal: That's true already | 
| [16:07] | Rex Cronon | in what way is it invasive? | 
| [16:07] | Lorca Linden | but this change should alleviate alot of the concerns people have been posting on blogs about pathfinding's effect on mainland regions / large exisitng builds | 
| [16:08] | Lorca Linden | ok that topic is now closed for this user group ;) | 
| [16:08] | Motor Loon | hehe | 
| [16:08] | Motor Loon | suspects that may have to be said a few more times | 
| [16:08] | Dahlia Trimble | so non-pathfinding TPV viewers should be able to edit objects? | 
| [16:08] | Falcon Linden | We have not determined how that will work yet | 
| [16:09] | Falcon Linden | Any questions not related to viewer interaction? :) | 
| [16:09] | Nal | I asked about Havok License in Oz's meeting. Seems that is still in process. But, hoped to be resolved by PF roll... or shortly after. | 
| [16:10] | Motor Loon | good news | 
| [16:10] | TheBlack Box | just the debug-mode thing again .. is that solved now ? is there a non-crasher sim with PF and without dbug-mode available for testing ? | 
| [16:11] | Falcon Linden | the bug has been resolved, yes | 
| [16:11] | TheBlack Box | i'd like to shoot pf-creatures without crashing the sim :) | 
| [16:11] | TheBlack Box | kk Pathtest4 ? | 
| [16:11] | Falcon Linden | theblack: use llCastRay :P | 
| [16:11] | Motor Loon | castray still has bugs, I had to stop using it on my boats | 
| [16:12] | TheBlack Box | hehe ... noone sells Castray weapons yet i think :) that one didnt work according to plan afaik :) | 
| [16:12] | Sandry Logan | is there something i can do to control how close a character gets to its when target using llNavigateTo? | 
| [16:12] | Falcon Linden | motor: really? I haven't seen any jiras about that | 
| [16:12] | Falcon Linden | sandry: use a different point? | 
| [16:13] | Motor Loon | I'll see if I can find one... | 
| [16:13] | Falcon Linden | motor: because the limits are basically disabled on pf regions | 
| [16:13] | Dahlia Trimble | limits? | 
| [16:13] | TheBlack Box | castray in general seemed to work well when i tested ... the low resolution on small prims is a bit of a bummer ... but it worked | 
| [16:14] | Sandry Logan | well, lets say the red box is my pathfinding dog and i want him to get on his bed (the blue square) | 
| [16:14] | Red Box | near | 
| [16:14] | Red Box | here | 
| [16:14] | Motor Loon | oh talking about jiras... can one of you lindens take a quick look at VWR-14674 it suddenly seemed to be a permissions violation when I try to access it | 
| [16:14] | Jira Helper | Status 499 | 
| [16:14] | Falcon Linden | theblack: low resolution? It uses the physics shape exactly | 
| [16:14] | Motor Loon | I suspect by accident | 
| [16:14] | Sandry Logan | it barely gets onto the edge of it | 
| [16:15] | TheBlack Box | Falcon: small spheres look like crystals to cast ray | 
| [16:15] | Falcon Linden | ah. Yeah, an object will consider itself at the goal when it's within one character radius, iirc | 
| [16:15] | And all I got was this lousy DN | most ER jiras are closed | 
| [16:15] | Motor Loon | https://jira.secondlife.com/browse/SVC-7603 | 
| [16:15] | Jira Helper | [#SVC-7603] llCastRay fails, when sitting on object that has crossed simborder https://jira.secondlife.com/browse/SVC-7603 | 
| [16:15] | Motor Loon | that was the one causing me problems atleast... | 
| [16:15] | Falcon Linden | theblack: something else is wrong there since spheres are always represented as true spheres with correct raycast properties in the engine | 
| [16:15] | Falcon Linden | motor: shouldn't happen on PF regions since the whole cast ray resource pool system is off | 
| [16:16] | Motor Loon | I see | 
| [16:16] | Motor Loon | that going to stay like that for all regions when PF hits full grid? | 
| [16:16] | TheBlack Box | Falcon: then we found a problem ... i tested that a lot for a llCastRay-based scanner that creates collada-files .... small spheres do absolutly not look like sphere in castray :) | 
| [16:16] | Falcon Linden | theblack: that was done intentionally so that you could llNavigateTo and object's position even if it was, e.g., a pole or a box or something | 
| [16:16] | Falcon Linden | theblack: jirafy | 
| [16:17] | Falcon Linden | Motor: yes | 
| [16:17] | Falcon Linden | Motor: unless we discover it causing problems | 
| [16:17] | Falcon Linden | but I don't expect that to happen | 
| [16:17] | Motor Loon | ok | 
| [16:17] | Motor Loon | good news | 
| [16:17] | Dahlia Trimble | how small? | 
| [16:17] | TheBlack Box | hmm ... i might .. kinda busy with other stuff these days .. but i will go into castray again somewhen | 
| [16:17] | M√¶stro Linden | for SVC-7603, the raycast could be occurring when the script hasnt' crossed into the new region yet | 
| [16:17] | M√¶stro Linden | so it's currently casting into the void | 
| [16:18] | M√¶stro Linden | and not hitting anything | 
| [16:18] | M√¶stro Linden | that should behave better when neighboring regions share collision shapes | 
| [16:18] | Dahlia Trimble | it would seem a waste to have a very accurate physics shape for small objects | 
| [16:19] | Rex Cronon | u could scan snowflakes with raycast:) | 
| [16:19] | TheBlack Box | Dahlia: that depends ... it it is a parametric shere the size wouldnt matter would it ? | 
| [16:19] | Falcon Linden | dahlia: a sphere is as simple a physics object as you can get | 
| [16:19] | Dahlia Trimble | agreed | 
| [16:19] | Dahlia Trimble | its just a point and a radius | 
| [16:19] | Falcon Linden | almost anything else we turn into a box at very small scales | 
| [16:20] | TheBlack Box | right ... but that is not what i observed ... will look at it again somewhen soonish and jirafy | 
| [16:21] | Falcon Linden | Well, if there are no other questions, we can wrap up early and get back to work :) | 
| [16:21] | Lorca Linden | i have nothing else on the agenda | 
| [16:22] | Dahlia Trimble | when do we get pathfinding NPCs with animated meshes? o.0 | 
| [16:22] | Jonathan Yap | I have a little question--my pathfinding character goes around about 0.2m above the ground -- should I write a jira for this? | 
| [16:22] | any1 Gynoid | I was wondering about ... the wierd thing... that happens... | 
| [16:22] | Falcon Linden | jonathan: no, you should adjust the visible shapes down by 0.2m | 
| [16:22] | any1 Gynoid | PF characters seem to zoom off to infinity.. .. sometimes... | 
| [16:22] | Falcon Linden | any1: oh no, not the wierd thing! | 
| [16:22] | Jonathan Yap | Thanks Falcon | 
| [16:22] | Motor Loon | lol | 
| [16:22] | any1 Gynoid | but really don't .. it's just optical illusion.. | 
| [16:22] | Falcon Linden | any1: we'll need to push releasing pathfinding off until at least 2017 to fix /that/ thing! | 
| [16:23] | And all I got was this lousy DN | sounds good to me | 
| [16:23] | Sandry Logan | is there anywhere we can read about what changes are in new server or viewer releases? (pathfinding as opposed to 'regular' release notes) | 
| [16:23] | And all I got was this lousy DN | will the physics stub be avalibe then sometime 2020? | 
| [16:23] | And all I got was this lousy DN | :P | 
| [16:24] | Lorca Linden | sandry we will start posting build notes to the wiki | 
| [16:24] | Lorca Linden | the main pathfinding wiki | 
| [16:24] | Falcon Linden | sandry: that depends, do you have access to our internal network? :P | 
| [16:24] | Jonathan Yap | http://wiki.secondlife.com/wiki/Category:Server_Release_Notes | 
| [16:25] | Motor Loon | your bird crap alot Mr.box | 
| [16:25] | Sandry Logan | no, not that i am aware | 
| [16:25] | Falcon Linden | Lorca: thanks for volunteering to write those up, that's awesome! :) | 
| [16:25] | TheBlack Box | Motor: yes but the plants will eat it :) | 
| [16:25] | Lorca Linden | lol | 
| [16:25] | Sandry Logan | jonathan thank you, are the pathfinding server notes in there too? | 
| [16:25] | Motor Loon | kinda makes me glad I'm not a plant | 
| [16:25] | Lorca Linden | and if you all have any neat pathfinding builds to show us | 
| [16:25] | Falcon Linden | I'll show you the script that will dump all the commit logs and you can parse those 800 or so into a nice pretty doc :) | 
| [16:25] | Lorca Linden | please do tell! | 
| [16:25] | Falcon Linden | Yes! We want to see cool pathfinding things! | 
| [16:25] | Falcon Linden | Lots of things! | 
| [16:26] | Jonathan Yap | Sandry, I don't think so | 
| [16:26] | TheBlack Box | shall i puch it a bit ? get a bit of an ecosystem going around us ? :)) | 
| [16:26] | TheBlack Box | dont shoot the brids, thou ,,, that crashes the sim if it is in debug-mode (collsisions) | 
| [16:26] | Jonathan Yap | For viewer : http://wiki.secondlife.com/wiki/Category:Release_Notes | 
| [16:28] | Falcon Linden | theblack: if shooting the birds still crashes, let us know | 
| [16:28] | Lorca Linden | before next user group if you want to place some critters / PF objects out for show and tell | 
| [16:28] | Lorca Linden | that would be awesome | 
| [16:28] | TheBlack Box | kk ... | 
| [16:28] | Motor Loon | o.O | 
| [16:28] | Motor Loon | Falcon on a mission | 
| [16:28] | Dahlia Trimble | any word on a in-world group for pathfinding? | 
| [16:29] | blue marker | Distance to red box: 1.066388 | 
| [16:29] | TheBlack Box | falcon: try shotguns for stress-testing | 
| [16:29] | Motor Loon | birdkilla | 
| [16:29] | Falcon Linden | I don't have one | 
| [16:29] | Lorca Linden | no update on that @ this moment, Dahlia | 
| [16:30] | Lorca Linden | any other questions? | 
| [16:30] | Lorca Linden | otherwise, I'm going to call this a wrap | 
| [16:33] | Shimmering Rift | /me emits a burst of static. | 
| [16:33] | Second Life | Teleport completed from secondlife://Aditi/secondlife/LI%20Devbox%202/133/100/23 | 
| [16:33] | TheBlack Box | sorry sorry sorry sorry sorry | 
| [16:33] | TheBlack Box | sorry sorry | 
| [16:33] | Lorca Linden | it's ok ;) | 
| [16:34] | And all I got was this lousy DN | i did have one quick question | 
| [16:34] | TheBlack Box | ummm ... still crashes the sim ;) | 
| [16:34] | Yuzuru | Sim crashed? | 
| [16:34] | Lorca Linden | apprently so mr box | 
| [16:34] | And all I got was this lousy DN | when do you think a [hysics stub will be avalible so we can compile the source? | 
| [16:34] | Horatio | whispers: Greeting TheBlack . | 
| [16:34] | TheBlack Box | :( | 
| [16:35] | Rex Cronon | somebody shot the birds? | 
| [16:35] | Horatio | whispers: Greeting Lorca . | 
| [16:35] | TheBlack Box | shotgun ... yeah | 
| [16:35] | Ima Mechanique | wow, that crash was so hard, even my mushrooms got sent home | 
| [16:35] | Yuzuru | Falcon? | 
| [16:35] | Dahlia Trimble | didi sim crash? | 
| [16:35] | Ima Mechanique | no need for me to clean up then. | 
| [16:35] | Lorca Linden | it did | 
| [16:35] | TheBlack Box | sim got rolled back yeah .. i think that is part of debug-mode (?) | 
| [16:35] | Ima Mechanique | bye all | 
| [16:35] | Lorca Linden | bye ima | 
| [16:35] | Horatio | whispers: Greeting Dahlia . |

| [16:36] | And all I got was this lousy DN | did you see my question, lorca? | 
| [16:36] | Rex Cronon | hi oratio | 
| [16:36] | TheBlack Box | Horatio need a properly sized capsule | 
| [16:36] | Lorca Linden | I did, give me one sec tankmaster, checking on that date | 
| [16:37] | And all I got was this lousy DN | ok thx | 
| [16:37] | Horatio | whispers: Greeting Draconis . | 
| [16:37] | Sandry Logan | he has a problem when he can't get to a location. the parcel that dahlia and rex ae in, he cannot navigate to | 
| [16:37] | Sandry Logan | horatio come | 
| [16:37] | Sandry Logan | horatio go theblack sit | 
| [16:37] | Rex Cronon | who is horation? | 
| [16:37] | Rex Cronon | the white bear? | 
| [16:38] | Sandry Logan | yes | 
| [16:38] | TheBlack Box | sorry again to all ... i would have shot the bird ... a linden told me it would been fixed :) | 
| [16:38] | Horatio | whispers: Greeting Yuzuru . | 
| [16:38] | Horatio | whispers: Noticed Rex | 
| [16:38] | Lorca Linden | OK, i'll have an update for that next user group tank |

| [16:39] | Lorca Linden | lol rex | 
| [16:39] | And all I got was this lousy DN | sounds good, thx | 
| [16:39] | TheBlack Box | :) | 
| [16:39] | Dahlia Trimble | so shooting them crashed the sim? lol | 
| [16:39] | Rex Cronon | ok. no shoot the lindens. shoot the birds:0 | 
| [16:39] | Lorca Linden | ok thanks all | 
| [16:39] | Rex Cronon | :) | 
| [16:39] | Sandry Logan | horatio explore 50 | 
| [16:39] | Lorca Linden | see you next week! | 
| [16:40] | Rex Cronon | tc lorca | 
| [16:40] | TheBlack Box | Dahlia yes ... i have been told that is related to collisions in debug-mode | 
| [16:40] | Lorca Linden | and please let us know if there are neat builds for us to check out | 
| [16:40] | Sandry Logan | bye Lorca | 
| [16:40] | Lorca Linden | we really like to see cool PF areas / critters | 
| [16:40] | TheBlack Box | http://www.youtube.com/watch?v=AAhrf2MHepY | 
| [16:40] | Lorca Linden | you can email pathfinding-beta@lindenlab.com with the SLurl | 
| [16:40] | Lorca Linden | thanks! | 
| [16:40] | Rex Cronon | is unatural for asuch a small vear to move so fast | 
| [16:40] | TheBlack Box | thats a longer video of the evo/eco stuff | 
| [16:41] | Lorca Linden | very cool, I will definitely watch that | 
| [16:41] | Lorca Linden | alright I'm out all, thanks! | 
| [16:41] | Rex Cronon | tc everybody and have a nice day | 
| [16:41] | TheBlack Box | thanks for the OH | 
| [16:41] | Rex Cronon | :) | 
| [16:41] | TheBlack Box | see you | 
| [16:41] | Lorca Linden | till next time | 
| [16:41] | Dahlia Trimble | ty lindens :) | 
| [16:41] | TheBlack Box | and i ll try not to crash the sims here all the time :) | 
| [16:41] | Lorca Linden | ;) |
