Advanced LSL Programming: Web Interaction and Sensor Applications

This tutorial delves into advanced programming with LSL, focusing on web interactions and sensor applications. Learn how to retrieve and parse an RSS feed using a designated URL, fetch the first link, and open it in the user's browser when touched. Additionally, discover how to create and manage sensors to detect nearby objects and residents. Master the llSensor function, its arguments, and the different types of searches available. Enhance your Second Life experience by visualizing sensors and finding object owners seamlessly.

  1. CS590VC – Tutorial 5 Advanced programming with LSL

  2. Interacting with the web • Retrieves an RSS feed from web • Parsing the feed

  3. What we will do ……. • Get the first link in the first item of the RSS feed • Open the link in the user’s browser when the object is touched. • The URL for the feed is: http://blog.secondlife.com/feed/

  4. Download the file: 0711_Fetching_A_URL_And_Parsing_The_Result

  5. A sensor application • To detect objects or residents near the selected object. • Event handler: sensor • Creating a sensor: llSensor & llSensorRepeat • Removing a sensor: llSensorRemove

  6. The basic function llSensor We have three arguments as follows: (a) A string: the name of the object/residents to search for. (b) A key: the unique ID of an object/residents to search for (c) A type: AGENT/ACTIVE/PASSIVE/SCRIPTED (d) Three Floats: the range to look for objects, the arc in radian to search, the rate in seconds to repeat the search

  7. llSensor type argument • AGENT: finds the avatar • ACTIVE: finds objects that are being acted on by simulator physics • PASSIVE: finds objects that are not ACTIVE • SCRIPTED: finds objects that have a running script

  8. What we will do • To turn the object into a transparent, phantom dimpled sphere that matches the area being searched by the sensor • To find object's owner, position this object in front of owner and point in the direction owner is looking
