Ludus in the current amber > compilation issue

I am trying to get Ludus working again with the current version.

I am facing a compilation error, associated with Javascript <> notation:

$ amberc Ludus.st -l Web -n HOS

Reading: Ludus.st

[Error: Compiler error in section:

Game methodsFor: 'events'

while processing chunk:

mouseMove: evt

        |canvasPosition windowScrollTop windowScrollLeft canvasRelative|

        windowScrollTop := <$(window).scrollTop();>.

        windowScrollLeft := <$(window).scrollLeft();>.

        canvasPosition := 'canvas' asJQuery position.

        canvasRelative := (canvasPosition left - windowScrollLeft) @ ( canvasPosition top - windowScrollTop ) .

        mousePosition := (evt clientX - canvasRelative x) @ (evt clientY - canvasRelative y).

a RethrowErrorHandler does not understand #handleError:]

How is this code now supposed to be written?

Once done, this will be good material for a screencast.

TIA

Phil

The keys instance variable (class Game) is initialized to
    keys := #().

I wonder what it is supposed to contain.

Yes I found the documentation and it quite comprehensive. However it
does not talk about instance variables and the general design. Mainly
method comments.

There is no ludus.html in https://github.com/philippeback/Ludus but 4
other html files

Documentation in Game.html

whileKeyPressed:do:
While the key given by the first argument is pressed, it evaluates the
block given by the second argument.


MyGame >> step
    self whileKeyPressed: Key upArrow do: [ superheroe moveCentreBy: (0 @ -1) ].



The code:

whileKeyPressed: aKeyCode do: aBlock
        ( ( keys at: aKeyCode ifAbsent: [ false ] ) and: [ keys at: aKeyCode
] ) ifTrue: aBlock

What is this last line supposed to do? Key code is 37. I open the
Sokoban game and only press 'UpArrow' once and the debugger comes up.

I really should take a deeper look at my old code, but the idea is:

((keys at: aKeyCode ifAbsent: [ false ]) and: [ keys at: aKeyCode ]) ifTrue: aBlock

If the keys dictionary doesn't have an entry for this key in it, evaluate to false. Otherwise evaluate to its value. Then, if the previous evaluated to true, execute aBlock.

Without having looked at it, I'm guessing the error may come from keys not being a Dictionary. Back in the day, Amber had a unique way to create dictionaries on the fly, but I think it's not there anymore, am I right?
