Animated Attachments Test

llTargetOmega

• Create 3 boxes and color the top sides red.
• Link 2 of the boxes together.
• Add the following script to both objects and verify the objects are spinning counterclockwise with the red sides still on top.

//llTargetOmega script
default
{
    state_entry()
    {
        llTargetOmega(<0,0,1>, 2, 1);
    }
}

• Attach the objects to your avatar.
• Verify the objects are still spinning counterclockwise with the red sides still on top.
• Edit the script and change the 2 to -2.
• Verify the objects spin in the clockwise direction.

• Add the following script to 2 boxes.

default
{
    state_entry()
    {
    llOwnerSay("spin off");
    llTargetOmega(<0,0,1>, 0, 0);
    }

    touch_start(integer total_number)
    {state spin;}
}

state spin
{
    state_entry()
    {
    llOwnerSay("spin on");
    llTargetOmega(<0,0,1>, 2, 1);
    }

    touch_start(integer total_number)
    {state default;}
} 

• Link the boxes together.
• Touch each of the boxes and verify they start and stop spinning.
• Attach the object
• Touch each of the boxes and verify they start and stop spinning.
• When both boxes are spinning around their own center, teleport to a different sim.
• Verify both boxes are still spinning around their own center.

llSetRot

• Create 3 boxs and color the top sides red.
• Link 2 of the boxes together.
• Add the following script to both objects and verify the objects are spinning counterclockwise with the red sides still on top.

//llSetRot script
float counter = 0;
default
{
    state_entry()
    {
        while(1)
        {
            llSetRot(llEuler2Rot(<0,0,counter>));
            counter = counter + 0.1;
            if (counter > TWO_PI) counter = 0;
        }
    }
}

• Attach the objects to your avatar.
• Verify the objects are still spinning counterclockwise with the red sides still on top.
• Edit the script and change the 0.1 to -0.1.
• Verify the object spins in the clockwise direction.

llSetLocalRot

• Create 2 boxs, one above the other.
• Color the North face of the bottom box red.
• Color the Top face of the top box green.
• Select the top box, then the bottom box, and link them together.
• Add the following script to the child(top) box (select Edit Linked Parts to do this)

//SetLocalRot script
float counter = 0;
default
{
    state_entry()
    {
        while(1)
        {
            llSetLocalRot(llEuler2Rot(<0,0, counter>));
            counter = counter + 0.2;
            if (counter > TWO_PI) counter = 0;
        }
    }
}

• Add the following script to the root object.

//SetLocalRot script
float counter = 0;
default
{
    state_entry()
    {
        while(1)
        {
            llSetLocalRot(llEuler2Rot(<0,counter, 0>));
            counter = counter + 0.2;
            if (counter > TWO_PI) counter = 0;
        }
    }
}

• Attach the object to your head
• Verify the red side of the root object rotates from top to left shoulder to chest to right shoulder
• Verify the child object rotates along with the root object and also rotates around it's own green face

llSetPos

• Create 2 boxes and link them together.
• Edit the child object (with Edit Linked Parts) and add the following script.

default
{
    state_entry()
    {
        llSay(0, "Hello, Avatar!");
    }

    touch_start(integer total_number)
    {
        float x = llFrand(40);
        float y = llFrand(40);
        float z = llFrand(40);
        llOwnerSay((string)x +", "+ (string)y +", "+ (string)z);
        llSetPos(<x,y,z>);
    }
}

• Click the child object a few times.
• Verify that the child object's position is restrained to 20m from your avatar.

Areas to expand this script:

llSetScale

llGetScale

llGetLocalPos, llGetRootPosition

llGetRot, llGetRootRotation, llGetLocalRot

Performance

• Make animated attachments that can be activated/deactivated by anyone shouting "on" or "off"
• Get 20 people together wearing the animated attachments
• Turn all the attachments on and off, and compare your framerate and network traffic.
• Is your framerate affected?
• Is your network traffic significantly higher?
