default state definition. When a state target; is encountered at runtime, if the current state and the target state are different:
- Trigger state_exit in the current state if it exists and clear the event queue.
- Change state to target, any listens are unregistered.
- Trigger state_entry in the target state if it exists.
If target state is the same as the current state, no state change occurs nor do any of the side effects.
Caveats
- On state change all listens are released.
Examples
default
{
touch_start(integer a)
{
state hello;
}
}
state hello
{
state_entry()
{
llOwnerSay("Hello");
state default;
}
state_exit()
{
llOwnerSay("Goodbye");
}
}
