World: r4wp

it is a bit difficult to see which one is solid, a different color 
might be better. It's a great game by the way.

I have to change it but first the kids to bed.

:))

Remove the bad lines version 1.04 works for me here. Mailed and uploaded 
just in between some modifications to clean things up a bit. Sorry 
for the inconvenience!

I think I know the source of this problem! The script did work on 
my machine without ANY error!
Why?

Because on MY REBOL environment labelfont still had a valid definition! 
It was still in memory from the earlier execution of the script. 
If tomorrow I start it again it will fail too!

Where is everybody?? 
(-:

Arnold, I looked at the script (btw very cool game!) and you can 
replace nested 'either in zet-label-kleur with 'case for better readability.

@Rebolek Thanks, that wil be on the list together with line width 
and color and font-size preferences, a multilingual help function 
and a resize mechanism. ((:

I am not fond of case/switch statements because for every language 
it is doing things differently then you expect, sometimes you need 
break statements because otherwise the next statement will perform 
too and other confusing stuff (not) happening. Rebuilding switches 
to nested ifs mostly solves these problems for me.

Of course REBOL's 'case you mean 'switch (REBOL 3 knows a 'case)

is pretty straightforward

To be honest, I liked the eithers better than the switch/default 
with an extra default block. I like the :p part of the script too, 
maybe it is better to rewrite this as :P

And switch is missing its case argument.. back to the eithers it 
is...

can't play the game like this :))

And switch is missing its case argument
 - what do you mean by this?

Rebol2 has a pretty straight forward case construct

you can use something like this:
case [
	n < 9 do-something
	n < 17 do-something-else
	n < 25 do-something-different
]

From the docs:

num: 10000
case [
    num < 10 [print "small"]
    num < 100 [print "medium"]
    num < 1000 [print "large"] 
    true [print "huge"]
]
huge

and switch is useful as it allows multiple tests

>> print switch 1 [ 2 1 [ "yes" ] 3 [ "no" ]]
yes

mirror is MUCH more fun now that the numbers on the edge react in 
real time.... really makes it one big step more playable.

its also much more obvious what the game is about.

it would also be much easier to help and add features if all the 
code where in english  ;-)

Not for Dutch kids :-)

got most of it understandable using google translate   :-)

This is the benefit of speaking another language than English that 
is the base for so many computerlanguages. You can say things like 
rij: array [100] where array: array [100] would be a sure syntax 
error, and rij means array in Dutch off course. If you are in need 
of additional translations, just say so. Next I will build a multi-lang 
support lbl-something/text: lbl-something-tekst and a preferences 
panel with file (mirror.ini or mirror-pref.ini) for language (En 
De Nl Fr Es Pt additional wishes?), mirror line-width normal(1)/bold(3 
wide) for placed or both kinds and/or the grid, color of added mirrors, 
color for ok color for not ok.

I'm adding a visual and interactive mirror tracing layer so that 
you can just hover over the numbers and they shoot a visible ray 
across the grid   :-)

(bouncing off the mirrors obviously)

Is yours also workig on android and iPhone yet? :)))

hehe  I wish  ;-)

I'm still working on figuring out the grid walking function... nice 
trick using xor and direction bits btw.

Thanks, when I did the trick in my Java applet I had never expected 
to use XOR at all ever. In Java I had an field of 10by10. I'll explain 
a little. Starting top left having an initial direction south start 
on the first field of the grid. determine the next direction to go 
then step and repeat until you step of the board stap=step r row, 
k for column (kolom) so stapr or stapk will be 0 or 9. then you are 
on the other end of the board. the values along the board is a series 
of 32 elements going clockwise around the board. Go to the next field 
clockwise when right your init direction is west etc.

When determining the values around the board you skip the ones that 
already have a value.

yeah, I'm pretty close to getting it ,  right now I'm adapting the 
function which returns the current row-column based on the position, 
since I need it to handle position outside the edge of the grid-box. 
 then I'll have the initial cell to use to start "walking" the grid.


in the end, I'll just add a refinement to the function which does 
the waking so it returns a block of all the tiles is crossed and 
an indication of what edges it came in and out of (to make it easier 
to loop and draw).

(right now = last I played... right now I'm at work, and can't play 
with this directly)

;-)

Having the 3 layers on top of each other was a nice REBOL feature 
saving a little time redrawing the grid and other mirrors as was 
necessary in Java (well I am not an experienced Java programmer, 
so it was necessary for me to solve it like that)

Somewhere I have read that someone had a problem with a similar drawing 
trick, can't remember where unfortunately, but it made me fear this 
trick might be impossible. Luckely it did work like I implemented 
it right on the first try..

Don't you hate that about work?

hehe

I have seen that one before
Try
lbl-language-text: "en"

It really should say " Choose your language here" or somthing

Was your mirror-lang.r loaded properly? the next error would be  
lbl-mirror-color-text .

That prediction was correct. Now diving in to find what was already 
loaded when building this, just like last time. Hang in there!

This one is tricky lots of prints now.

Fixed it but now the ****really bad words**** radio buttons are protesting 
again D:

It works now, and I made the files .rebol extension again.

@Marco: great work!

Blowing on the whistle ;-) It's Win only because the RepRap is Win 
only.

Marco, very nice.

Very cool. We have been looking into doing something with the RepRap, 
preferably with Red
