(The information is useful but it does not belong in the state_exit article, it should be in the touch articles and state article. Also, the user may not care about touch_end, so the advice is bad.) |

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
<lsl>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\"");
}
}</lsl>
Notes
While the default state_entry is triggered on script reset, state_exit is not triggered prior to the reset.
