    llSetLinkPrimitiveParamsFast & PRIM_TEXTURE

    in LSL Scripting

    Posted · Edited by Rachel1206

    I am getting this script error message:

     llSetPrimitiveParams error running rule #2: unknown rule.

    The code is a below, worked without problems, then suddenly the error message above - I have tried to replace the texture name llList2String(digits, value) with the UUID of a texture - same error... I cannot see, what causes the error, I'm blind to the bug... :(

        llSetLinkPrimitiveParamsFast(
        LINK_THIS,
        [
            PRIM_TEXTURE,
            4,
            llList2String(digits, value),    // List of UUID textures
            <1.0, 1.0, 0.0>,
            ZERO_VECTOR,
            0,0
        ]);

     

    Help needed , Please

    To get the display name of an avatar:

    string strName= llGetDisplayName(llDetectedKey(0));

    Now it is an bad idea to use display name in an objects name field, because display names can contain characters outside valid range of an objects name field and description field. Username though is ok llGetUsername()

    If you want to use display names, use for example llSetText( strName, <1.0, 1.0, 1.0>, 1.0);

    I would use llDetectedTouchST() to get the coordinates (X,Y) and use the formula cosv= vector(A) x vector(B)/length(A)*length(B) to find the angle.

    To my knowledge there is no easy way to do it  - unless there are some handy LSL functions B|

    I'm a bit stumped.

    Yes, you understood it correct

    • texture to be displayed
    • product description
    • price of item

    The script is original from a book, often copies floating around  the internet/web sites miss something or the content is broken, because information found in the original book/article is omitted.

    In the dataserver part use this to bypass the remark lines of the note card:

    if (llSubStringIndex(data, "//")==-1)
    notecardList += [data];

     

    Rotation around two axises

    in LSL Scripting

    Posted · Edited by Rachel1206

    To follow up on Rolig's excellent explanation - some thoughts:

    Quaternions is to overcome the limitations of a vector based system - basically quaternions makes smooth interpolating between two arbitrary points easier. If we only used vector based operations in say a script, we would need very complex and time consuming calculations to establish the matrix of the objects position(s).

    See also: https://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation

    And yes - very few humans - find it essay to to make quaternions - we do though something similar automatic and with nearly with no delay, with our movements and body parts positioning, even using tools with our hands at same time - and talking and maybe drinking coffee also  - all smooth in real time with right positions and movements.

    The computer though - and games mechanics in particular - need another approach (quaternions) and this conflicts with our natural understanding of orientation in 3D real world, hence making it hard to understand and use.

    OK, you can right click and select edit of Maitreya Mesh Body HUD V4.1 in your inventory.  It looks like the rotation is wrong, try this numbers before getting a redelivery:

    Rotation:
    <0.00000, 270.00000, 270.00000>

    Position:
    <0.58981, -0.30068, 0.86731>

    Wow, thanks for all of those ideas. My PC is less than a year old with an SSD drive, Windows 7....would upgrading to 10 make a difference? Do you think  the tweaks you suggested are still worth trying? I think my next step was to put my cache on a different drive (a partitioned one). I guess all I am out is some time. If worse comes to worse, I guess I will have to downsize my house some. I really do not have a lot of furnishings though, certainly far less than some people. Lol...that was the fun of upgrading my PC, so that I could put out all of my knickknacks and art. My old PC would not run above low, so I could not put hardly anything out and the scene was not pretty at all, lol. I guess I hear so many different things about what effects performance that I do not know what to look for in objects to decorate with. Oh well. Thank you very much. I will try to put the cache on its own drive I think, see what happens. 

     

    Windows 10 is faster provided all your hardware is supported; I got better performance after upgrading to Windows 10 from Windows 7 (64 bit).

    The tweaks I suggested should not be necessary on a new system with SSD, but making partitions for cache and disable indexing on those partitions should give a performance boost, but less compared to old style hard-disks.

    But  try this first

    Have you tried to purge all the texture files in the cache? Corrupted texture files could degrade performance. Assuming you use Firestorm, be sure Firestorm is closed. Now the cached textures are in the folder …FirestormOS_x64\texturecache with sub-folders named “0” to “f“

    With File Explorer in Windows, select the folder “texturecache” – delete the folder“texturecache”  and be patient, there can be a huge amount of files, purging can take minutes.

    Firestorm will rebuild the folders again, so no worries. Start Firestorm and log in,  if you get better texture loads and no problems after having purged the texture cache, corrupted texture files were the problem.

    That Pesky Script Error Trying to Stop Animations - PERMISSION_TRIGGER_ANIMATION permission not set

    in LSL Scripting

    Posted · Edited by Rachel1206

    I would ensure correct handling of animations by doing as below:

        timer()
        {
            llSetTimerEvent(0.0);
            
            //      Sanity check - did our avatar somehow disappear without saying goodbye?
            if (llGetAgentSize( llGetPermissionsKey()) != ZERO_VECTOR )
            {
                //  Never assume permissions are valid!
                if (llGetPermissions() & PERMISSION_TRIGGER_ANIMATION)
                {
                    llStopAnimation(  MY_ANIMATION );
                    
                    //  Force looped frame animations to stop
                    llStartAnimation("stand");
                    llStopAnimation("stand");             
                }
            }
        }

    Further use of the event attach( key id ) and check for valid key,  also ensure correct handling. And yes, lot of stuff and checks for something really simple.

    Some further tips for boosting performance on older systems with Windows 10

    If you do not have a SSD (solid state drive) and is using Windows 10 and your computer is some years old, the following can improve performance.

     

    Windows Service: Superfetch

    On some hardware/Windows 10 combinations this otherwise brilliant service can make performance sluggish, especial with programs/games requesting and freeing memory all the time.

    How to disable Superfetch? Press Windows key + R, type "services.msc" and hit Enter, find Superfetch in the list, right click it and disable the service.

    You can always enable it again.

     

    Disable indexing of files

    Now this is ONLY recommended if you have your FS/SL Viewer cache on a separate partitions ( another hard-disk). Right click the hard-disk on which you have your cache,
    select Properties, uncheck "Allow files on this drive to have contents indexed in addition to file properties". Be sure to click "Apply changes to drive LETTER:, sub-folder and files"

    Let it remove indexing, which can take some time. Be patient  and wait to it is done!

     

    Use separate partitions for caching

    I have my viewer cache and sound cache on two separate partitions sized 12 GB each ( hard disks I and K  in my case) and  the above steps boosted my performance.

     

    Optimize - defragmentation

    Optimize you cache hard-disk(s) regularly.

    Experience ID - my own owned Experience?

    Where do I find/get the experience key to my own owned Experience? I have searched the wiki, examined the Experience tab dialog in FS, but either I'm blind or it is buried deep down some obscure place. I want to list the experience details as below.

    key keyXP= ....

    llGetExperienceDetails( keyXP )

    ban_lines_001.thumb.png.7f6a6ef6b3e7ea660ad99357fe57d98b.png

    The joy of test driving... ban lines on a public road owned by Governor Linden - both sides of the road with ban lines.

    And many likes this without making any sense. Now the place I passed, is public on the other side, which makes it even weirder.

    And lot of ban lines on empty land and like above killing  a vehicle while no scripts allowed. And if you are really lucky, you are kicked with zero seconds warning, and you never entered the parcel/land area... :S
