Community news and announcements / SyntaxBomb - Code a game competition
« Last post by Richey on 03. November 2017, 21:33:19 »
Here is another forum for indie and retro game coders - its called 'SyntaxBomb'

They are running a 'Code a game competition'.

Too late for entries now but I thought the site and the games might be of interest to people here...and there is always next year  :)

Looks like most entries are coded in different flavours of Blitz BASIC but one of the entries is coded in BBC BASIC for Windows 'Forces of Darkness' by David Williams a.k.a BasicBoy

http://www.syntaxbomb.com/index.php/topic,3325.45.html

Here is a YouTube video of the game in action:

David Williams is also the author of the games found on the site mentioned in this older thread:

OK so too much candy = revolutions, rebellions and revolting retributions, with parades and fireworks thrown in for decoration. :D

Somehow, Richey, I can't see the American people celebrating an act of terror against a sitting government on Nov. 5th :D

(Though what we actually celebrate is one of the perpetrator's punishments which would make even the most pro-Capital-punishment states populations cringe in unison - but such is the British justice system, I suppose!)

Hi Richey, what do they do for Halloween across the pond? Anything special for teachers?

Hi B+

Well, Halloween has British Celtic roots and is derived from Gaelic and Welsh traditions before being later influenced and shaped by Christianity. As D says, we celebrate it pretty much the same as you do in the US with pumpkins, dunking for apples (we still do that!) and children dressing up as witches and ghouls etc. No trick-or-treaters this year though and my own daughter went to a Halloween party. Nothing special for teachers in my daughters school, although the children had a Halloween disco. Now we are looking forward to Guy Fawkes Night on 5th Nov - lots of fireworks, which I guess you don't celebrate in the US (or anywhere else except in the UK - and perhaps UK dependent territories and Commonwealth countries  :) )

Mike, do you still visit?

Hi B+,

Yes, I do from time to time, though mostly lurking without actually signing in. I've been massively into old-skool rock'n'roll and related retro audio gear this year as my primary hobby, rather than into programming in BASIC. And my computers will have to wait yet a while longer. :)

We don't have anything like Halloween in our culture. But if we had, I guess it should've been the date of the Great October Socialist Revolution (well, y'know, Lenin, Stalin, bolsheviks, and stuff). ;)

Hi Cybermonkey,

Your Fasnet reminds me of New Orleans Mardi Gras.

Hi D,

Yes, feeding sugar to already overactive spirits is evil, that is the trick from a treat.


Dang it! I forgot JJ  :-[

Well maybe he doesn't go in for this child's play anyway?


Hi JJ,

How goes it with you and your part of the woods?


Oh and Peter!

Hi Peter,

I missed you too! heck, you might actually give the Re-occurrence a go at translation.


The scariest part of this whole deal is my spelling of reoccurrence.

Round our way it's "All Hallows' Eve" when traditionally evil spirits, warlocks and witches would be knocking around up to no good. The idea was to carve a scary face in a pumpkin and light it from the inside with a candle before leaving it outside your front door - it would scare the evil away.

Now the American tradition of "Trick or Treat" has taken hold over the last few decades, and the roots of the day have been all but lost in the scramble for as much sugar as it is possible to get in a tacky bucket. Now the pumpkin is used to signal (around here at any rate) that the occupants of the house are welcoming of Trick-or-Treaters and have stashes of sweets indoors.

I love it personally, but there are a fair few that don't.

Not a big deal here in Germany. We have Carnival (usually in February), or as we call it in southern Germany: "Fasnet".

Sorry, no screen shots. I didn't want to spoil the surprise ending.

JRS, maybe you will give us a shot?

D, feel free to Smash it after Halloween, with appropriate music of course. :D

Galileo, yes should work in YAB.

Rick3137 or Marcus, yep SdlBasic and Naalaa too!

Hi Richey, what do they do for Halloween across the pond? Anything special for teachers?

Hi Cybermonkey, and in Germany?

In the states, Halloween is second biggest holiday of year, some of the decorations are better than Christmas as far as imagination goes.

Who did I miss?

Aurel, but I hear they have Halloween every week in Croatia, so no big deal.

Mike, do you still visit?
