[Vehicles vs. sim crossings, why it's so awful]

Again this unexplained term. What are you even rambling about?  You started to use your animats-newspeak term on page 3 of this thead and continue using it like everyone knows what you are talking about... I bet everyone in the thread thinks of this problem as something different as you didn't define it anywhere...

@Fionalein: animats said: "half-unsit" - the vehicle makes it across the sim crossing but, for some reason, the avatar does not. In that situation you can't unsit.

@animats: Thanks for your work on all this. Your persistence and patience is much appreciated.

An extended version using states to do this cleanly

 

list    gData = [];integer gDataCount;integer gDataLine;list    gNoteNames;integer gNoteCount;integer gNoteIndex;/* initialize -------------------------------------------------------------*/default{    state_entry()    {        llSetText("Initializing... please wait", <1.0,0.0,0.0>, 1.0);        gNoteCount = llGetInventoryNumber(INVENTORY_NOTECARD);        llWhisper(0, (string)gNoteCount);        integer i;        for (i = 0; i < gNoteCount; i++)            gNoteNames += [llGetInventoryName(INVENTORY_NOTECARD, i)];        gNoteIndex = 0;              state data;      }}/* data fetch -------------------------------------------------------------*/state data{    state_entry()    {       llSetText("Fetching data... please wait", <0.0,0.0,1.0>, 1.0);       gData = [];       gDataLine = 0;       llGetNotecardLine(llList2String(gNoteNames, gNoteIndex), gDataLine);    }    dataserver(key id, string data)    {            if (data != EOF)        {                    gData += [data];            llGetNotecardLine(llList2String(gNoteNames, gNoteIndex), (++gDataLine));            }        else  // no more lines of data in notecard            state main;    }         state_exit()    {        gDataLine = 0;        gDataCount = llGetListLength(gData);        gNoteIndex = ((++gNoteIndex) % gNoteCount);    }         }/* ----------------------------------   put user actions in state main*/state main{    state_entry()    {        llSetText("Ready for user actions", <0.0,1.0,0.0>, 1.0);            }    touch_end(integer n)    {        llSay(0, llList2String(gData, gDataLine));        if ((++gDataLine) == gDataCount)            state data;     }}

When doing this kind of task then the prequisite is that we are going to partition the data in some way

Option 1) partition the data into separate files (multiple notecards) and treat each file as a page. A synchronous application operation when using states

Option 2) retain the data in one file (single notecard) and do in-memory paging

The downside with option 1 is the delay when reading pages from file into memory

The downside with option 2 is that this is an asynchronous operation. The main issue is with the reader while the in-memory page is being updated, so that the reader doesn't get invalid data

Approaches for Option 2 are:
 a) pause the application interactions while reading, making the application synchronous
 b) remain application asynchronous by implementing a reader request queue manager as well as a data request manager

A clean way to do this when all the notecard data can fit into the script's memory

 

list gData = [];

integer gLine = 0;

 

/* ----------------------------------------------------

   use default state to load notecard data into memory

   then on data loaded go to state main

*/

default

{

    state_entry()

    {

        llSetText("Loading data... please wait", <1.0,0.0,0.0>, 1.0);

        

        llGetNotecardLine("ANotecard", gLine);

    }

 

    dataserver(key id, string data)

    {

        if (data != EOF)

        {        

            gData += [data];

            llGetNotecardLine("ANotecard", (++gLine));    

        }

        else  // no more lines of data in notecard

            state main;

    }

}

 

/* ----------------------------------

   put user actions in state main

*/

state main

{

    state_entry()

    {

    llSetText("Ready for user actions", <0.0,1.0,0.0>, 1.0);        

    }

 

    touch_end(integer n)

    {

    llSay(0, llDumpList2String(gData, "\n"));

    }

}
