Scripting

Greifer Monday

by

Today we are seeing new griefer toy creating chaos.

The new Linden Realm’s Advanced Creator Tools currently in Magnum is being user to create teleporters with broken permissions. When taken outside Magnum the toys will teleport people without their permission.

This morning I got to see the Cornfield for the first time. Then they teleported a load of people into the Scripting UG Meeting.

An immediate fix is for a region owner to turn scripts off.

Or, if your region is in the Magnum Release Channel it is immune.

Otherwise expect chaos until the Lindens figure out a fix, which may be to roll the package running on Magnum to the main grid.

PS: Motor Loon says, “Hi mom!”

UPDATE: The server updates rolled  late Monday seems to have fixed the problem.

PATHBUG-136

PATHBUG-136 – llSetRot() completely broken in RC PF 12.05.10.256473. This is a problem only on the Pathfinding (PF) enabled servers/regions.

Andrew Linden thinks he has this one fixed and believes the fix for that was deployed yesterday, Thursday. I’m not sure if he meant to AGNI or ADITI and didn’t think to ask him at the time.

Andrew has moved on to fixing Keyframe bugs in the Pathfinding.

Server Scripting Meeting

Rebake the Navmesh

There was a problem where rebaking the Navmesh would go into a perpetual pending state. Falcon Linden thinks he has that fixed. The change rolled to the AGNI (I think) PF Test Regions Friday morning. Falcon wants you to report if that happens again. Include the time and region name in your report.

#SL News Week 22

We have a bit more news on this week’s roll outs to the Release Channels. Actually some BIG news.

More information below the fold.

Blue Steel

This channel will be updated Thursday instead of Wednesday. The package will contain an avatar render change. The avatars in the Library will now have pre-baked textures.

You probably know that the viewer downloads all the textures worn by an avatar and bakes them intop a composite texture. So, skin, tattoos, alpha layers, undershirt, and shirt layers are baked into a composite. That is uploaded to SL and is the image others download. Even you download a copy, which is why you see your avatar start blurry then render crisp, which is the end of the bake, then go blurry and then hopefully crisp again.

Region Idling

This is the server update that is advancing to the main grid today, Tuesday. I’ve been writing about Second Life® Region Idling for a few days now. So, if you don’t know about it see: #SL Region Idling and #SL News Update Week 20.

Open Source Meeting

Threaded Region Crossing

I’ve been writing about the Region Crossing Phase I code for some time, since about February. This is a major refactor of region crossing code. It touches many parts of the Second Life system. Because of its complexity it has been a difficult write. We have seen lots of problems from it. It has been rolled back from the Release Channels a number of times.

It looks like this code will stay on the Le Tigre and Magnum channels this week.

#SL News Week 19

by

Kelly Linden provided some information on the Linden Scripting Language (LSL) function llGetAgentList(). The server maintenance package with this new function rolled to the main grid Tuesday. It rolled in spite of a problem. See JIRA item:

SCR-311 – llGetAgentList() with scope AGENT_LIST_PARCEL or AGENT_LIST_PARCEL_OWNER returns empty list when attached to avatar.

Server Scripting User Group

Of course those most interested in getting this feature intended to use it in avatar attachments. Frustrating. Kelly believes they can fix the problem and we’ll either see the fix pushed to the main grid or pop up in a release channel, depending on how well the fix goes.

#SL Pathfinding Wk17 & Wk18

A little catching up… RL work has interfered with my making a couple of User Group meetings. One of the Lindens was kind enough to send me transcripts for the meetings I missed.

Land Impact

The Lindens were testing the modified Land Impact system in week 17. They were using the algorithm that set a cap on Streaming/Download Weight of 1 on all non-mesh-prims.

Also, the Script Factor of increasing Server Weight by 0.5*prim_count for unscripted-prims and scripted was switched to 0.5*prim_count + (0.25*number_of_scripts) with a cap of 2. Rounding is done on linksets. The Lindens believe that change would only cause the Land Impact cost of existing objects to decrease.

While one could probably prove the deceasing cost belief mathematically, on a practical level bugs tend to add chaos to and invalidate clean logical proofs. So, they test.
