#SL Scripting UG Week 2

by

Tuesday the next server maintenance pack should roll out to a release channel. For scripters this roll will have llSetRegionPos(), the frame_number parameter for llGetEnv(), and some llSetKeyframedMotion() bug fixes. We’ll find out which channel gets the update Tuesday.

Roll outs are a bit off and the pipeline is a little dry because of last week’s network switch failure. So, I think we will see release channels roll Tuesday instead of Wednesday.

A backend feature has been added. Kelly Linden says it is a % scripts run stat. This tells one what percentage of scripts ran in the last frames as an average. We will eventually see it in the viewer. But, it has the QA pipe to make it through before we see it. Version 3.2.7 made it to the development alpha today. So, % scripts will likely be one or two versions behind that.

This new stat is the average percentage of scripts that ran in the last frames. A 100% average means all scripts are running in every frame.

LSLEditor Updated

by

For those using the LSL Editor it’s time to update. This update adds lots of constants and a function or two. This brings it much closer to the current LSL (Linden Scripting Language) state. If you don’t know about the LSLEditor, it is a third party offline editor and debugger for SL scripts. It is  open source. … Read more

#SL Scripting News Week 51

by

Kelly Linden learned that when iTunes locks up the SL Viewer can’t open… Computers are full of complications. The viewer will never get past Initializing VFS, if iTunes freezes. This is Windows. No telling what will happen on a Mac.

Server Roll Out

Kelly says the server maintenance release from Le Tigre seems to be running well. This is the release that got rolled back from the main channel once. It is good it is running well. Because this is the release we will run until next year.

The roll out means both LSL functions llTransferLindenDollars() and llGetParcelMusicURL() are on the main grid.

Region Crossings

The rumor about more region crossing failures came up. Apparently there is no statistical data to tell the Lindens that is the case. So, unless people are filing JIRA’s it would be an invisible problem from the Linden side of the equation.

Kelly says the Lab is currently working on projects to improve region crossings. The Lab is also working on projects to reduce what Kelly called ‘up time bloat’. I suppose that is things like memory leaks and other things that tend to degrade region performance over time.

Main Channel

This week the code from Le Tigre/Magnum rolled to the main channel. This is a server maintenance pack. It includes the LSL function llTransferLindenDollars(). The thread that links to is now about 5 pages long. The details of the function are:

  • Attempt to transfer amount of L$ from the owner of the object to ‘id’. Requires PERMISSION_DEBIT. Returns a key used in a matching transaction_result event for the success or failure of the transfer.
  • New LSL event: transaction_result(key id, integer success, string data) This event is triggered from an llTransfer* call (currently only llTransferLindenDollars).
  • id: matches the return value of the llTransfer call and if the transaction was a success will match the ‘transaction id’ shown in transaction history on secondlife.com
  • success: TRUE if the transfer succeeded otherwise FALSE.
  • data: On successful transactions will contain a CSV of destination ID and amount transferred. In failure cases it will contain an error tag on failure.
  • Error Tags for llTransferLindenDollars:
    • LINDENDOLLAR_ENTITYDOESNOTEXIST – The destination UUID is not a valid agent.
    • LINDENDOLLAR_INSUFFICIENTFUNDS – The source agent does not have enough L$ for the transfer
    • INVALID_AGENT – Destination agent is not a valid UUID
    • INVALID_AMOUNT – Amount is <= 0
    • THROTTLED – The scripted L$ throttle was hit for this object owner.
    • MISSING_PERMISSION_DEBIT – The script does not have debit permission
    • GROUP_OWNED – The object is group owned and thus can’t give money
    • TRANSFERS_DISABLED – L$ transfers are disabled in the region
    • EXPIRED – The simulator timed out waiting for a response from the back-end service.
    • SERVICE_ERROR – There was an error connecting to the back-end service

    #SL Server News Week 50

    by

    I’ll do this update and another later in the week. We have some good news and some bad news.

    First, the good. It seems the kernel (3.0) upgrade is working and roll has reached 20% of the grid. We may see that roll out increasing its pace. It does mean a region restart so many regions will be seeing 2 restarts today and some tomorrow. Others will be seeing an additional restart later in the week.

    FBS Dagger's Large Airplane

    Second, the Le Tigre region was rolled to the main channel. (Release Notes) Some people are reporting teleporter device problems. It seems to be associated with posJump(vector target_pos). However some people are having problems and others are not.
