Description

! Event: moving_start( ){ ; }

Triggered when task begins moving


Caveats

  • The moving_start and moving_end events require special handling when scripting attachments.
    • After adding or editing a script you must:
      • Take off the attachment and then wear the attachment again.
  • This event is also triggered when an object is rezzed (unless, presumably, you happen to rez it in precisely the same spot it was before.)
  • This event's behavior is undefined for non-physical movement (llSetPos, movement via build tool, etc.)
  • This event is triggered when an object initiates a new keyframed motion, or when motion is resumed via KFM_CMD_PLAY

Important Issues

   Behavior of moving_start() and moving_end() is inconsistent.

integer trigger_multiple = FALSE; // This bad boy will prevent spam of moving start event
integer trigger_slave = 1;

setPhysical(integer status_physics)

}
