(Arrivals <numbers...>)
  Define the Arrivals variable for this class. This is twenty-five numbers
  each of which is either zero or one. They are meant to be on five lines
  of five numbers each, making a 5x5 matrix, where the centre means this
  object's location.

Bizarro
  Means that objects of this class created using the Create instruction
  will be created in the bizarro world by default. (This has no effect on
  objects placed in the level editor.)

(Climb <number>)
  Define the Climb variable for this class.

(CollisionLayers <numbers...>)
  Define the CollisionLayers variable for this class. The format is the
  same as for Misc4 (see below), but only the low 8-bits are usable.

  arrivals (according to the Arrivals variable), the corresponding bits
  are set in the Arrived variable. If this value is nonzero, then it will
  also send a ARRIVED message during the trigger phase. You can write all
  bits of this variable, but only the low 25-bits can be read back; if you
  write a nonzero number with only the high bits set, then it will still
  be triggered but will be read back as zero.

Bizarro : bool [c]
  Set if this object is in the bizarro world. Objects in the bizarro world
  are invisible and intangible, and mostly do not interact with other
  objects. However, they can still be accessed/affected by anything that
  references it directly, it is still possible to broadcast messages to
  them, and they are still affected by most turn-based actions (although
  not the compatible part of the trigger phase). Objects in the bizarro
  world are effectively stealthy as well, so do not cause messages due to
  being moved, created, or destroyed. In some circumstances, attempting
  to change this flag will have no effect.

Busy : bool
  If any object has either the Busy or UserSignal variable set, then the
  player input is blocked, and the turn may continue. Use this to control
  the timing of effects in LASTIMAGE blocks.

Class : class [ro]
  The class of this object.

Climb : int16/int32 [c]
  In order for this object to move, this object's Climb must equal or
  exceed the Height of all objects at the target location, otherwise it
  is prevented from moving.

CollisionLayers : int8 [c] [ro]
  Any set bit means no other object with that same bit set in this field
  may exist at the same location.
  may exist at the same location. (There is no effect in bizarro world.)

Compatible : bool [c] [ro]
  The compatibility flag. Class definitions imported from EKS Hero Mesh
  always set this flag; in new puzzle sets it is normally not set.

Density : int16/int32 [c]
  Determines the order that objects are stacked within each cell. When an

  Destroy the given object without sending any messages.

band  ( in1 in2 -- out )
  Bitwise AND.

(bit <numbers>)  ( -- number )
  Make a number with only the specified bits set, given numbers 0 to 31.

BizarroSwap  ( x y | obj1 obj2 -- number ) **
  Attempt to exchange either two objects (one in the bizarro world, one
  not) at the same location or all objects at the specified location into
  or out of the bizarro world. If it is successful, then the result is 0.
  If unsuccessful due to CollisionLayers, then the result is the bits in
  the CollisionLayers which are conflicting; if unsuccessful due to any
  other reason then the result will be 256.

bnot  ( in -- out )
  Bitwise NOT.

bor  ( in1 in2 -- out )
  Bitwise OR.

  the code of the class it is inheriting.

,Super  ( ? -- ? )
  Same as Super but return to this code after it is finished.

swap  ( x y -- y x )

SwapWorld  ( -- ) **
  Exchange the entire game with the bizarro world. Sometimes, this might
  fail due to CollisionLayers bits; in this case, it is an error.

Synchronize  ( slot startimage -- ) **
  Start a synchronized animation. Give the slot number of the animation,
  and the starting image number. The length and speed are defined in a
  global definition, and the animation is always a non-oscillating loop.

Target  ( -- bool )
  Check if Arg1 and Arg2 are the coordinates of this object. It is an
