Create a container with hotspots

Texture them properly

Scripting – What was touched? ClickedPrim=llDetectedLinkNumber(number); if (ClickedPrim==3) { state rotation_three; } else if (ClickedPrim==9) { pageURL="http://google.com/search?hl=en&q=librarian";} … An arrow launches state rotation_three which changes the prim’s rotation Or – the hotspots launch set the URL

ClickedPrim=llDetectedLinkNumber(number);

if (ClickedPrim==3)

{ state rotation_three;

}

else if (ClickedPrim==9)

{ pageURL="http://google.com/search?hl=en&q=librarian";}

…

An arrow launches state rotation_three which changes the prim’s rotation

Or – the hotspots launch set the URL

Scripting – do that pull down llLoadURL(llDetectedKey(0), "Click 'Go To Page' to visit.", pageURL ); llDetectedKey senses the avatar who touched it You get a nice message on the pulldown

llLoadURL(llDetectedKey(0), "Click 'Go To Page' to visit.", pageURL );

llDetectedKey senses the avatar who touched it

You get a nice message on the pulldown

Advanced Scripting 2 Building a simple HUD

Steps overview Find the Dice container Empty it (mostly) and add a blank script Add the script parts and test it on the ground Attach to HUD top and resize & position

Find the Dice container

Empty it (mostly) and add a blank script

Add the script parts and test it on the ground

Attach to HUD top and resize & position

Clean the dice Remove everything but the “dice_drop” sound Set “Stretch textures” before resizing Set the object to nonphysical and .2 on a side

Remove everything but the “dice_drop” sound

Set “Stretch textures” before resizing

Set the object to nonphysical and .2 on a side

Starting the script Two variables that are predefined: list rots = [< 0.00000, 1.00000, 0, 1>,<0.00000, 0, 0.70711, 0.70711 >, < -0.00000, 0.00000, -1.00000, 0.00000 >, < 0.00000, 0.00000, -0.70711, 0.70711 >,< 0.00000, 0.00000, 0.000, 0.70711 >,< 0.00000, -1, 0.000, 1 >]; list numbers = [&quot; 一 &quot;,&quot; 二 &quot;, &quot; 三 &quot;, &quot; 四 &quot;, &quot; 五 &quot;, &quot; 六 &quot;]; 6 quaternions describe rotation of dice to make each sides show. The list of Chinese numbers is for fun.

Two variables that are predefined:

list rots = [< 0.00000, 1.00000, 0, 1>,<0.00000, 0, 0.70711, 0.70711 >, < -0.00000, 0.00000, -1.00000, 0.00000 >, < 0.00000, 0.00000, -0.70711, 0.70711 >,< 0.00000, 0.00000, 0.000, 0.70711 >,< 0.00000, -1, 0.000, 1 >];

list numbers = [&quot; 一 &quot;,&quot; 二 &quot;, &quot; 三 &quot;, &quot; 四 &quot;, &quot; 五 &quot;, &quot; 六 &quot;];

6 quaternions describe rotation of dice to make each sides show. The list of Chinese numbers is for fun.

Rotation and Eulers

When the prim is born: default{ state_entry() { llSetRot( (rotation) llList2String(rots,0)); } “ Set the rotation of the prim to the first item in the list “0”. Notice the type assignment making the string into a rotation.

default{

state_entry()

{

llSetRot( (rotation) llList2String(rots,0));

}

“ Set the rotation of the prim to the first item in the list “0”. Notice the type assignment making the string into a rotation.

Prim is touched = set random rot. touch_start(integer total_number) { integer random = llFloor(llFrand(6.0)); llSetRot((rotation)llList2String(rots,random)); “ Take a random number 0 to 6 and round it down (floor)” “Set the rotation of the prim to a random item in the list”

touch_start(integer total_number)

{

integer random = llFloor(llFrand(6.0)); llSetRot((rotation)llList2String(rots,random));

“ Take a random number 0 to 6 and round it down (floor)” “Set the rotation of the prim to a random item in the list”

Prim is touched = have some fun llOwnerSay(llList2String(numbers,random)); llPlaySound(&quot;dice_drop”, 1.0); } } “ Use the same random number to pick a Chinese character and say it to owner.” “ Play the sound at volume 1”

llOwnerSay(llList2String(numbers,random)); llPlaySound(&quot;dice_drop”, 1.0);

}

}

“ Use the same random number to pick a Chinese character and say it to owner.”

“ Play the sound at volume 1”
