Description

Event: state_exit( ){ ; }

Triggered on a qualifying state transition.


Caveats

  • Events queued during state_exit, are dumped before the next state is entered. use state_entry to avoid this, when possible. See state for further caveats.


Examples

default
{
    state_entry()
    {
        llOwnerSay("Entering default state");
    }
    touch_end(integer detected)
    {
        // Note: NEVER do a state change from a touch_start event -
        // - this can result in a missed touch_start on re-entering this state
        // Here we do the state change safely from within touch_end
        state other;
    }
    state_exit()
    {
        llOwnerSay("leaving default state");
    }
}

state other
{
    state_entry()
    {
        llOwnerSay("Entering state \"other\"");
    }
    touch_end(integer detected)
    {
        state default;
    }
    state_exit()
    {
        llOwnerSay("leaving state \"other\"");
    }
}

Notes

While the default state_entry is triggered on script reset, state_exit is not triggered prior to the reset.

Deep Notes

Signature

event void state_exit(  );
