Thanks ! I didn't get any display problem too.

        I haven't fixed this - that is more problematic.

        At issue is that it is pretty easy to know that 2 one spaced objects can
     
     swap

        However, for 2 spaced objects, this is much more difficult.  Think of

        For the player to swap with the wyvern, either the player has to hop two

        Now at least the push code does work now, so in that second example, if
     
     you

        I'm not sure what to do with this long term.  One could certainly make
     
     the

        I looked at the code to do the swap position - it isn't as straight
     
     forward -

      the check to see if space is available sort of needs to be custom written

      this - first, you need to see if the space the monster is moving into has
     
     a

      This gets pretty tricky - in the second case above, all of those would
     
     initially

      seem to check (wyvern would get moved to place player current is and place
     
     a

      peice of it currently is).  The player is also trying to move to a piece
     
     the

      wyvern is currently in.  However, that space will still be occupied after
     
     the

      wyvern moves.  So now you need to do the logic that the player would swap

For this  second problem, reading your drawing and descriptions, I think
it's perhaps more logic to keep the push system you write.

But the lack of swapping can sometime really block, with, for example,  this
map :

(P is the player, G is the ground and W is the Wivern)
---------
|
     
     PWW|
     
     |
     
     GWW|
     
     ------|G|

(It can apear, for example, where there is stairs under P)

You would like to go to the exit on the bottom-right, and the wyvern is
blocking you...
In this case, swapping would work fine, but if the ground on the bottom-left
where a wall, you where really blocked.


So I had an idea that could work around, and that could be helpfull elswhere
:
     
     
     
What do you think of a command, a spell, a saying, a skill or something else
to "Banish" your pets :
 --> so when you don't need anymore a pet, you could get out of it.
 --> so when a pet is blocking your way, you could get out of it too.

Yes I know you can kill it, but it's perhaps not really a good idea to be
forced to kill a pet when it has well helped you and you don'need it
anymore...

What do you thing of something like that ???

Olivier.
