#SL News 2 Week 43

by

I’ve been distracted on weekends, so I’m just getting to writing up the last of the news from last week (43). There is no great news, but there are some interesting things.

Large Group Edit

The code for this change rolled out Wednesday. It had problems and was rolled back the same day. It is however currently running on the Snack Release Candidate Channel. You can get the details of that in: Second Life Large Groups Edit Week 43.

Server Scripting Meeting Oct. 2012

Part of the reason for getting this change up and running is to get it where Third Party Viewer Developers can test their viewers against the new server code. To use the new Group Editing code on the server viewers need to change the viewer code. Getting the code on a release channels allows TPV Dev’s to get their QA people and Beta testers involved.

The Problem

The package with the Large Group Edit code had a problem with the llSenor() function. It stopped returning a sorted list of objects. The sort is on distance. Not being able to figure out what is close or far meant breedables were not able to find food or each other… you know… to breed… The lack of loving was tragic.

The problem has been fixed. So, this week (44) we should see it move into one of the main release candidate channels.

#SL Large Groups Edit Week 43

by

Getting this update out is proving to be a problem. Not so much the large group editing as the things it is packed with. You know, everyone bundles…

Oskar Linden posted in the SL Forum about the problems with the roll out to the Magnum Release Candidate Channel. See: Large Groups Fixes LIVE on AGNI.

The short story is the roll out was rolled back Wednesday due to issues in the llSensor() function.

Interest List

Andrew Linden is still working on rewriting the interest list code. He says he is seeing light and should have working code soon. He hopes to have it done this week (43).

Server-Scripting Oct 2012

Andrew told us, “…Dan Linden noticed that the “number of objects in view” right after the login curtain comes up, in a busy region, is less in my code than server-trunk, which means that my interest list wasn’t doing as good of a job of loading initial content. But I think I’ve got that fixed, and am planning on implementing the “gradually increase camera far clip on login” behavior that some 3rd party viewers have already hacked on their end, which should help the initial login sorting.”

Blake Sea and Le Tigre

You probably remember the region crossing problems sailors and pilots had with the previous Havok Physics Engine update. Putting different versions of Havok on adjacent regions creates problems. Havok was never designed for use across multiple versions of Havok. It’s use by Linden Lab™ is the only known use that encounters that problem. So, we will likely have crossing problems with each update of Havok.

Morris Region, ADITI Grid

With the addition of Pathfinding and possible other gaming features to Second Life™ we are likely going to see more updates of Havok, but fortunately, less crossing problems. ‘More’ is like a couple a year.

Region Organization

Some weeks ago the Lab tried placing adjacent regions in the same or adjacent servers, physically adjacent servers. This made what Oskar Linden described as a ‘MASSIVE improvement’ in performance. Now it is standard operating procedure to keep the regions and servers organized.

Scripting & Server News Week 42

For the release candidate on Le Tigre we have some new information that comes from the wiki release notes just recently updated. Some of those are:

Havok Update

The Havok Physics Engine updates to version 2012.1 in the release candidate. In week 35 I reported that this version was coming. At the time we had just updated to 2010.x, I think. This update enables Havok’s terrain optimized that simplifies the physics shape of the terrain for improved performance. This feature can be disabled by region owners and estate managers with the Region Debug Console command “set optimize_terrain false“.

Havok Physics

Some are reporting vehicle crossing are slower.

llGetSimStats

llGetSimStats() has yet to show up in the Linden Scripting Language (LSL)  pages of the wiki. Fortunately the release notes say:

Currently, this function accepts only [[SIM_STAT_PCT_CHARS_STEPPED]] as its parameter, which returns the % of Pathfinding characters skipped each frame, averaged over the last minute.  The returned value corresponds to the “Characters Updated” stat in the viewer’s Statistics Bar.

#SL News 1 Week 42

This Tuesday we got a roll to the main channel. This is the package that was on Blue Steel. This is the code to improve performance for Large Groups. It is not the Large Group Editing changes that Baker has made. Those changes are in a package still stuck in QA.

It has been quite since the roll out. That usually means things are working as expected.

Sever-Scripting Meeting September 2012

Magnum

Is going to continue to run the same package it has had for the last couple of weeks. This is a package that adapts the simulator to the new hardware. It contains various configuration changes for the Denebian OS running in the region servers. I have no information whether this is identical to last week or some configuration settings are changing. Whatever the case, it is expected users won’t see any difference.
