State

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.

default { events }

• event

events

–

one or more events

The default state definition.

state target { events }

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

target state definition.

Caveats

• On state change:
  • All listens are released.
  • The event queue is cleared
• The default must be defined before all others.

Examples

default
{
    touch_start(integer a)
    {
        state hello;
    }
}

state hello
{
    state_entry()
    {
        llOwnerSay("Hello");
        state default;
    }
    state_exit()
    {
        llOwnerSay("Goodbye");
    }
}
