PASS_* flag

Whether Touches are passed to the root prim depends not only on which PASS_* flag is selected, but may also depend on if there is a script that in the prim that handles one of the touch events. For this reason most users will want to use PASS_ALWAYS or PASS_NEVER as they do not have this variable behavior.

The default value for this attribute is PASS_ALWAYS.

pass Constant	Value	touch Script	No touch Script	Description
PASS_IF_NOT_HANDLED	0	not passed	passed	Touches are passed if there is no script handling the event in the prim.
PASS_ALWAYS	1	passed	passed	Default: Touches are always passed to the root.
PASS_NEVER	2	not passed	not passed	Touches are never passed to the root.

Caveats

• Has no known effect if called from within the root prim.
• This has no effect when called on the root prim.

Examples

Make a two prim LINK_SET (Object). Name the root "Parent" and the child "Child". To the root add this script:

integer told;

default
{
    state_entry()
    {
        told = FALSE;
    }
    touch_start(integer total_number)
    {
        if(!(llDetectedLinkNumber(0) == llGetLinkNumber()))// We can use a condition like this to filter from which prims touches are triggered.
        {
            llSay(0, "My child tells me you touched it. Abuse report pending.");// This will only be spoken if the child is touched twice.
            told = TRUE;
        }
        else
        {
            if(!told)
                llSay(0, "You can touch me all you like");// The unaware Parent leads you on.
            else
                llSay(0, "If I had my way you would have your hands cut off!");// Not any more.
        }
    }
}

And to the child add this script -

integer once_is_too_often;
default
{
    state_entry()
    {
        llPassTouches(FALSE);// Innocent child doesn't know to say something the first time.
        once_is_too_often = FALSE;
    }
    touch_start(integer total_number)
    {
        if(llDetectedLinkNumber(0) == llGetLinkNumber())// Again we check who is being touched.
        {
            if(!once_is_too_often)
            {
                llSay(0, "If you touch me again I'm telling.");
                llPassTouches(TRUE); // But if a second time, it will tell.
                once_is_too_often = TRUE;// And then fall silent.
            }
        }
    }
}
