9. Learn how to control Walk Run Fly Control View + drag mouse

10. Creating Objects Right click any place in the island to Edit Choose Create button Pick one shape and click any location where you want to place the prim at.

11. Editing Object If you click the object, you can change the xyz coordinate Rotate the object with keep pressing Ctrl Change the size of the object with keep pressing Ctrl + Shift

12. Link Objects together Shift + click objects you want to link together Then, Ctrl + L to link If you want to edit only a part of linked object, click Edit linked.

13. STATES A "State" in LSL is a section that is running, and waiting for events. Only one state can be active at a time per script. Every script must have a default state. Except for the default state, each state is defined by the word STATE followed by the name of the state.

14. EVENTS Events are inside of states. When that state is active, those events wait to be triggered and run the code inside them. "state_entry": triggered by the state being enteredstate_entry "touch_start": triggered when anyone touches an object.touch_start

15. FUNCTIONS Functions lay inside of events. Built in functions: ◦ all start with two lowercase L's. E.g., llSay(0, "Hello")llSay ◦ llSay takes arguments of a number and a string. User define functions: ◦ You can define own function before default ◦ E.g.: sayOutloud(string message) { llSay(0, message); }

16. Scripting! Right Click Object -> edit -> Content -> New Script -> Open New Script This script will basically say "Hello, Avatar!" on the public channel which is 0, and will then say "Touched." on the public channel when a user touches or clicks it.

17. Output in a chat box 10m range: ◦ llWhisper(Channel, "WHISPER STUFF"); 20m range ◦ llSay(Channel, "SAY STUFF "); 100m range ◦ llShout(Channel, "SHOUT STUFF"); Anywhere on the region ◦ llRegionSay(Channel, "REGION SAY STUFF"); Use Channel 0 to talk, others (-2147483648 ~ 2147483647) for obj-to-obj communication

18. LSL variables examples integer count = 2; //A whole number float measure = 1.2; //A number with decimal places string chars = "Lee"; //Any text within " " list words = ["This", "Is", "A", "List"]; list entries = ["A list may contain many types of values such as", 2, 1.2, ]; vector vec_2 = ; //Generally used for position as xyz, but can be used to store 3 numbers to be parsed out later rotation _rot = ; //Can also be used to store 4 numbers to be parsed out later

19. On/Off Example Using States default { state_entry() { llSay(0, "turning on!"); llSetColor(, ALL_SIDES); } touch_start(integer total_number) { state off; // sets the script to a new "state" and starts running "state off" } state off { state_entry() { llSay(0, "turning off!"); llSetColor(, ALL_SIDES); } touch_start(integer total_number) { state default; } If you click, it changes the state and changes the color

20. Use If /else. default{ state_entry(){ llSay(0, "Hello, Avatar!"); } touch_start(integer total_number){ if (llDetectedKey(0) == llGetOwner()){ llSay(0, "Owner Touched."); } else{ llSay(0, "Someone Else Touched."); } If the Owner touch, it says “Owner Touched.” Else it says “Someone Else Touched”

21. Obj-to-Obj communication Sender default { state_entry() { } touch_start(integer total_number) { llWhisper(5, "SayOne"); } Receiver default { state_entry() { llListen(5,"","",""); } listen(integer channel,string name, key id, string message) { if(message == "SayOne") { llSay(0, "One"); } Object 1 sends a command “SayOne” through the channel 5. Object 2 listens to the channel 5, and whenever it receives the message “SayOne”, It says “One”.

22. Use PHP key requestid; default { state_entry(){} touch_start(integer total_number){ requestid = llHTTPRequest("http://.../a.php?ids=a", [HTTP_METHOD,"GET"],""); } http_response(key request_id, integer status, list metadata, string body){ if (request_id == requestid{ llOwnerSay(body); } Send http request to a certain php file and receives the response

23. If you wanna program in C# OpenMetaverse foundation provides a C# library to directly connect to the SL http://openmetaverse.org/
