Description

Event: state_entry( ){ ; }

Triggered on any state transition and startup


Specification

Triggered

  1. Script save or adding to object
  2. State change
    • A state_exit is triggered in the old state and the state_entry is triggered in the new state. All other events in the queue are lost as a result of the state change.
  3. On script reset, either by client or llResetScript/llResetOtherScript
  4. When the object is rezzed without a saved script status
    • If it was a copy taken from inworld
    • If the event had not been triggered due to no-script land.

Not Triggered

  1. When the object is rezzed with saved script status, not even on change of owner
    • Use on_rez event in this situation
  2. When the task moves to another SIM, nor on SIM restart

Caveats


Examples

default
{
    state_entry()
    {
        llSay(0,
            "You either just saved the script after editing it"
            + "\nand/or the script (re)entered the default state.");
 
        llSetText("Click to change states", <1.0, 1.0, 1.0>, 1.0);
    }
 
    touch_end(integer num_detected)
    {
        // Note: NEVER do a state change from within a touch_start event -
        // - that can lead to the next touch_start on return to this state to be missed.
        // Here we do the state change safely, from within touch_end
        state two;
    }
 
    state_exit()
    {
        llSay(0, "The script leaves the default state.");
    }
}
 
state two

        state default;
    }
 
    state_exit()

        llSay(0, "The script leaves state 'two'");
