Lsl notecard reader3/30/2023 This is an implementation of a binary search. It is fast as is, and can be adjusted to be faster if you have an idea about the notecards you will be getting the size of. We are also rescued by the invariant that objects cannot have the same name in the inventory which eliminates hash collisions on same names. Notecard Reader: There is an LL function that does this now: // llGetNumberOfNotecardLines // // This is a fast way to find the number of lines in a notecard. Since 293 does not equal 289, it deletes 289 such that the description reads:Īs you can see, by XOR-ing with the position of the character in the name of the notecard we can avoid collisions in palindrome cases. In case we now delete the notecard named aab, the script will start to compute the hash of the notecards in the inventory. make a vb script that checks the database for new changes, if it detects a new line, it shows a popup with 'name is now online or offline and then delete that row. if their status changed, make an http call to a database with the name and new status. If we read the baa notecard, the description will now read: add a list to store if the person was online/offline at last check. If we now add a different notecard, named baa, the dropbox script will update the description to: ![]() After reading, the script will update the description to: Now suppose that we read the notecard by touching the object and requesting it. The script will thus update the description to: Contribute to Outworldz/LSL-Scripts development by creating an account on GitHub. This allows us to determine which notecard was deleted because, in case of a deletion, the string in the primitive's description will not have the same hash numbers such that we delete from that string whenever we have a mismatch.įor example, suppose that we drop a notecard named aab into the dropbox. Free LSL Scripts for Second Life and Opensim. Whenever a notecard is read, we generate that hash and concatenate it in the primitive's description. More precisely, for a notecard named aaac the hash stored will be 296. Secondly, to track "read" notecards, every time a notecard is sent to an agent, we generate a hash of all the characters of the notecard name, using Pedro Oval's Ord function, plus its index in the name. nPose is an LSL script for use in Second Life that allows one or more avatars to sit on (and otherwise control). To address the first challenge we use key-value data storage to store a CSV serialized string in the primitive's description, thus making sure that the data is still there after a simulator restart. They can (and should) be used to eliminate the dataserver hell that LSL puts a scripter through. Secondly, LSL does not report which notecard has been added or deleted - it only triggers the changed event handler and with the INVENTORY_CHANGED flag we can only know that something in the inventory has changed. OSSL Script Library/Simple Notecard Reader This script is intended to demonstrate the use of osGetNotecard functions in OSSL. Firstly, if we were to use the script memory to store the notecard names and their read status, after a restart that data will be gone. Note: This function delays the script for 0.1 seconds.Įxample: // Read out a complete notecard from the object's inventory.There are some particular challenges to this script. This is widely used in a lot of products so the end user can easily configure some settings without the need to modify a script. Requests from notecards that contain embedded inventory items will always result in EOF, regardless of the line being requested. Read info from a notecard in LSL Since LSL scripts are not meant for storing permanent data, the best way to achieve this, besides using a database, is using a notecard. Note that lines longer than 255 characters will be truncated without any indication that this has been done. ![]() If name is not a valid notecard, or if the notecard is empty, the object will print to the Script Errors/Warning window, “Couldn’t find notecard NAME” where “NAME” is the name of the invalid notecard. you should keep in mind that any time you edit and save such a notecard, it will get a new key. Name can be either a string containing the name of a notecard in the object’s inventory, or a key pointing to a notecard (that can be anywhere and doesn’t have to reside in the object). ![]() The key returned by llGetNotecardLine is a unique identifier which will be supplied to the dataserver event as the queryid parameter. You can get the number of lines in a notecard with llGetNumberOfNotecardLines. If the requested line is past the end of the notecard, the dataserver event will return the constant EOF (“End Of File”) string. This function fetches line number of notecard name and returns the data through the dataserver event. Key llGetNotecardLine( string name, integer line)
