State of the Project Presentation• Project Overview• User Interface Design• Architecture

▫ Second Life objects▫ Linden Scripting

Language▫ Classroom concerns

• Software Demo


26

Objects - Primitives• Basic shapes

▫ Square▫ Torus▫ Sphere▫ Cone▫ Cylinder

• Complex Objects▫ Made of joined prims▫ Imported from design

programs▫ Cost to upload


27

Objects – Prim Limits• Limited Number Of Prims

▫ Determined by land• Monthly Land Use Fees

▫ Sponsor has 512 m2

• Limit Cost To Sponsor▫ Import objects▫ Reduce prim count


28

Objects - Imported• Sculpted Prims

▫ Image based▫ Grid mapped

32x32 grid▫ Limited base geometries


29

Objects - Imported• Imported mapping is

awkward• May not render correctly


30

Object - Imported• Benefits

▫ Allows for complex objects

▫ Works well on small scale• Detractions

▫ Does not scale well▫ May not render correctly▫ Difficult to texture


31

Linden Scripting Language• LSL, Second Life Scripting

▫Java-like syntax▫Nearly complete language▫Runs in sandbox

• Attachable To Any Object▫Drag script into object container▫Provides actions to objects

• Easy Execution▫Run at touch action▫Run at specified event▫Run at specified time


32

LSL – System Calls• Provided Functions

▫ Get system info▫ Get object info▫ Get user info▫ Change object properties

• Example System Calls:▫ llGetTextureRot▫ llGiveInventoryList▫ llPlaySound▫ llDetectedTouchPos

http://wiki.secondlife.com/wiki/LlGetTextureRot

http://wiki.secondlife.com/wiki/LlGiveInventoryList

http://wiki.secondlife.com/wiki/LlPlaySound

http://wiki.secondlife.com/wiki/LlDetectedTouchPos


33

LSL – Attach To Object• Place Script In Object

▫ Objects have contents• Script Auto-Starts

▫ Runs at all times▫ Waits for action


34

LSL Door Action Scriptdefault { touch_start(integer total_number) { //defines action event rotation rot = llGetLocalRot(); //define rotation variable if (rot.z == 0) { //if door is in closed position rot.z = .707107; //rotate 90 degrees rot.s = .707107; } else { //if door is open, set to closed rot.z = 0; rot.s = 1; } llSetLocalRot(rot);}}


35

Classroom Concernsor “a spoonful of sugar”…


36

Blackboard-Second Life IntegrationFrom a team at Ball State:• Register a student’s newly acquired avatar name from

within Second Life• Once registered, maintain online status of each student• Display the class list with avatar name, class name,

and SL Online Status• Provide the SLURL of the Class• Provide class list information to Second Life, including

BB administrator list• Allow logging of discussions in second life into the BB

Discussion forums• Security based on validation with blackboard.


37

SchedulingMinimally, students coordinate with

proctors and instructorsIn-game scheduling:•Groups have notices and proposals•Notices are one-way announcements•Proposals are open to voting


38

Other Concerns•Tutorial document – succinct but general•“Learner engagement type” –

collaboration, presentation, experience?•User tests will reveal the average

learning curve
