The correct title of this article is state. The initial letter is shown capitalized due to technical restrictions.

state target;

state target;
• label target name of a state to run

When a state target; is encountered at runtime, if the current state and the target state are different:

  1. Trigger state_exit in the current state if it exists and clear the event queue.
  2. Change state to target, any listens are unregistered.
  3. 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.

state target{ events }

• label target state name
• event events one or more events

State definition.

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");
    }
}
