Free Hero Mesh

Moved : bool
  After a Move instruction successfully moves this object, it will set
  this flag. During the trigger phase, it will send the MOVED message
  to all objects which have moved; you can set or clear this flag by
  yourself if you want to cause it to trigger even though it didn't
  move or to not trigger even though it did move.

Moving : bool
  This flag indicates that a deferred movement is scheduled for this
  object. The direction of movement is specified by the Dir variable.

Player : bool [c] [ro]
  If this object is the player. This is used implicitly as the From of
  some messages sent by the game engine, and has a few other purposes.
  (Normally, a level should have exactly one object of such a class,
  although this is not mandatory; any number (including zero) is allowed.)

Shape : int16 [c]

  values for the sides that are touching will be compared. If the Sharp
  value for one is greater than the Hard of the other, then the object
  with insufficient Hardness is destroyed.

Shovable : int16 [c]
  Defines what directions the object may be shoved, where bit0 means east,
  bit2 means north, bit4 means west, and bit6 means south. Bit1, bit3,
  bit5, and bit7 can be used for diagonal shoving; the high 8-bits are
  currently unused but may be used in future.
  bit5, and bit7 can be used for diagonal shoving. Higher bits are
  reserved for future and should not be used.

Stealthy : bool [c]
  If this flag is set, then the Arrived and Departed variables of other
  objects are not automatically set when this object moves.

Strength : int16/int32 [c]
  When this object's code tries to move this or other objects by the use

  Similar to Move but adds Strength to Inertia without resetting Inertia.
  (The reason this exists is for compatibility with a bug in EKS Hero
  Mesh; you probably do not need to use this yourself.)

,Move+  ( obj dir -- bool ) **
  As Move+ but for a specified object.

+Move  ( dir -- bool ) **
  Schedules a deferred move for this object in the specified direction
  (which may be absolute or relative). Some things are checked at this
  time, while other things are checked at the time that the movement will
  be made; its working is different from non-deferred movements. The
  result is true if the move was scheduled or false if it isn't. (Note:
  Do not confuse +Move with Move+; they are unrelated.)

,+Move  ( obj dir -- bool ) **
  As +Move but for a specified object rather than necessarily this one.

-Move  ( dir -- bool ) **
  Cancel a deferred move in the specified direction, and possibly also
  other things that are shoved by it. The result will be true if it was
  scheduled and successfully removed, or false otherwise.

,-Move  ( obj dir -- bool ) **
  As -Move but for a specified object rather than necessarily this one.

MoveNumber  ( -- number )
  The current move number. This is initially zero, and is advanced after
  each input phase (before the beginning phase).

MoveTo  ( x y -- bool ) **
  Teleports this object to the specified coordinates; the MOVING message
  (and PLAYERMOVING if applicable) are sent to check if it is allowed.

  from the specified object.

ObjLayerAt  ( layers x y -- obj )
  Find an object with the given CollisionLayers bits set at that location.
  If you specify multiple bits, it finds one with any of those bits. (It
  is not possible for there to be more than one such object.)

ObjMovingTo  ( x y -- ... )
  Push on the stack all objects scheduled to move to the specified X and Y
  coordinates. There may be zero or more such objects; you can add a mark
  to the stack in order to delimit this list (it won't do so automatically,
  since you may be putting multiple lists together).

ObjTopAt  ( x y -- obj )
  Find the object on the top at the specified location. The result will be
  zero if that location is vacant or out of range.

over  ( x y -- x y x )

oz?  ( any -- bool )

  Display a percentage sign; does not consume an argument.


=== Messages ===

This section describes when the various standard messages are sent to
objects, and what return values are expected. (Do not confuse CREATE with
CREATED, or DESTROY with DESTROYED, or COLLIDE with COLLIDING; they have
CREATED or DESTROY with DESTROYED; they have different purposes.)
different purposes.)

(Some standard messages are in the names.js file but not used; do not use
them in your own code, since their names and meaning may change later. The
ones listed here are (probably) considered stable, and their numeric value
(used in level files) will (probably) remain unchanged.)

ARRIVED
  Sent during the trigger phase if the Arrived value is nonzero. Arg1 is
  the saved Arrived value. The Arrived variable will usually be set
  automatically; see the section about variables.

BEGIN_TURN
  Sent to all objects during the beginning phase (the phase after the
  input phase). From is an object with the Player flag (if there is any),
  Arg1 and Arg2 are the X and Y coordinates of that object, and Arg3 is
  the most recent return value from a KEY message. The beginning phase may
  be suppressed; if it is, then the ending phase is also suppressed.

BLOCKED
  When scheduling deferred movement, if the moving object is blocked by
  another object, then the moving object sends this message to the object
  which is blocking it. From is the object attempting to move, Arg1 and
  Arg2 are that object's coordinates, and Arg3 is 1 for +Move or 0 for
  -Move. Of the return value, bit0 clears the Moving flag (causing the
  move to fail), and bit1 causes it to not send any more BLOCKED messages.

COLLIDE
  Received when this object is trying to move into a location where there
  is a collision, so it can't move there. Of the return value, bit0 means
  to prevent the movement (even if the objects are moved out of the way or
  destroyed in order to make room), bit1 means to not send any COLLIDEBY
  messages, and bit2 means to pretend the move attempt was successful even
  if it isn't successful. Even if bit0 is set, that won't prevent sending

  attempt is successful even if it isn't (there is no effect for creating
  objects; this bit is meaningful only for moves), and bit4 means that if
  necessary, it will try to destroy this object to make room. From is the
  object attempting to move here, and Arg1 and Arg2 are its location (if
  attempting to create an object, then From, Arg1, and Arg2 are all zero).
  Arg3 is the class of the object being moved or created.

COLLIDING
  Called when deferred movement is being performed if the move cannot
  occur due to a collision with some other object. From is the object
  that it is colliding with, Arg1 and Arg2 are its location, and Arg3
  is the type of collision (0 if this object is trying to move into a
  stationary object, 1 if another object is trying to move into this
  stationary object, 2 if two objects are trying to move into the same
  space, or 3 if two or more objects forming a loop are trying to move
  into each other). There is no guarantee that this will only be called
  once; sometimes it will be called multiple times for a single collision
  or for multiple collisions with the same objects. (TODO)

CONFLICT
  Called during scheduling of a deferred move if it is already currently
  scheduled to move but in a different direction. Arg1 is the direction
  that it is trying to schedule the move in. If the return value is false
  then the schedule fails; if true, then it succeeds.

CREATE
  Sent when the object is created by the Create instruction. This is done
  after the object is created, but before sending any other messages. The
  From is the object that created it. The return value will be used as the
  Arg3 of the SUNK and CREATED messages it might send if appropriate. From
  is the object which executed the Create instruction to create it.
