llStartAnimation

Summary

Function: llStartAnimation( string anim );

129	Function ID
0.0	Forced Delay
10.0	Energy

Start animation anim for agent that granted PERMISSION_TRIGGER_ANIMATION if the permission has not been revoked.

• string

anim

–

an item in the inventory of the prim this script is in or built-in animation

To run this function the script must request the PERMISSION_TRIGGER_ANIMATION permission with llRequestPermissions.

Caveats

Permissions

Do not depend upon the auto-grant status of permissions. Always use the run_time_permissions event. If the script lacks the permission PERMISSION_TRIGGER_ANIMATION, the script will shout an error on DEBUG_CHANNEL and the operation fails (but the script continues to run). Once the PERMISSION_TRIGGER_ANIMATION permission is granted there may be no way to revoke it except from inside the script (for example, with a new llRequestPermissions call) or if the script is reset. For Viewer 3.6.7 and up: If the object is not attached to the permission granter but is in the same region, then Me>Movement>Stop Animating Me will revoke both PERMISSION_TRIGGER_ANIMATION and PERMISSION_OVERRIDE_ANIMATIONS (other permissions will remain).

• If anim is missing from the prim's inventory then an error is shouted on DEBUG_CHANNEL.
• Only 30 animations can be played at a time. (Prior to 1.25.4 the limit was 15 and prior to 1.25.3 there was no limit at all.)

Examples

default
{
    touch_start(integer detected)
    {
        llRequestPermissions(llDetectedKey(0), PERMISSION_TRIGGER_ANIMATION);
    }
    run_time_permissions(integer perm)
    {
        if (perm & PERMISSION_TRIGGER_ANIMATION)
        {
            llStartAnimation("sit");
            llOwnerSay("animation will end in 5 seconds");
            llSetTimerEvent(5.0);
        }
    }
    timer()
    {
        llSetTimerEvent(0.0);
        llStopAnimation("sit");
    }
}

Add an animation or pose inside the same object as this script:

string animation; // the first animation in inventory will automatically be used
  // the animation name must be stored globally to be able to stop the animation when standing up

default
{
    state_entry()
    {
        // set sit target, otherwise this will not work 
        llSitTarget(<0.0, 0.0, 0.1>, ZERO_ROTATION);
    }
 
    changed(integer change)
    {
        if (change & CHANGED_LINK)
        {
            key av = llAvatarOnSitTarget();
            if (av) //evaluated as true if not NULL_KEY or invalid
                llRequestPermissions(av, PERMISSION_TRIGGER_ANIMATION);
            else // avatar is standing up
            {
                if (animation)
                    llStopAnimation(animation); // stop the started animation
                llResetScript(); // release the avatar animation permissions
            }
        }
    }
    
    run_time_permissions(integer perm)
    {
        if (perm & PERMISSION_TRIGGER_ANIMATION)
        {
            animation = llGetInventoryName(INVENTORY_ANIMATION,0); // get the first animation from inventory
            if (animation)
            {
                llStopAnimation("sit"); // stop the default sit animation
                llStartAnimation(animation);
            }
        }
    }
}

Common script to play some kind of a "holding animation" while an object is attached to an avatar:

string animation_name = "hold";

default
{
    // Whenever this object is attached or detached...
    attach(key id)
    {
        if (id)
        {   // If it was just attached, request permission to animate.
            llRequestPermissions(llGetOwner(), PERMISSION_TRIGGER_ANIMATION);
        }
        else
        {   // It's being detached...
            if (llGetPermissions() & PERMISSION_TRIGGER_ANIMATION)
            {   // If we have permission to animate, stop the animation.
                llStopAnimation(animation_name);
            }
        }
    }

    // Whenever permissions change...
    run_time_permissions(integer permissions)
    {
        if (permissions & PERMISSION_TRIGGER_ANIMATION)
        {   // If permission to animate was granted, start the animation.
            llStartAnimation(animation_name);
        }
    }
}
