Old School Demo 1 (PC)

It’s an incredibly poorly kept secret that I love a good DYCP, but the latest Cosine release which includes one wasn’t actually programmed by me for a change! Old School Demo 1‘s name is a subtle, nuanced hint at what it might contain…

…and yes, it has a parallax starfield, Amiga-style colour rolling effects, two scrollers – one with the aforementioned DYCP – and a remix of the Uridium 2 titles tune playing in the background which was done by Jason Page himself. I sort of had a hand in the graphics, aNdy used the Cosine copyright symbol logo I did a while back but reworked it for the PC.

The download includes some handy PureBasic source code as well for those who fancy a dabble and, because aNdy wrote the code in part for folks who wanted to learn their way around said language, it’s been pretty much documented to within an inch of its life.

Workprint – April 2018

I haven’t had a lot of time for programming recently so there’s not much to talk about today – the workprint posts are moving to Tuesdays in case I forgot to mention that – but one thing I’ve been doing which is sort of related is a spot of digital archaeology, working through a pile of older hard disks in what turned out to be a surprisingly fruitful attempt to locate a few bits and pieces which have gone astray over successive machine rebuilds. One of the things I found is this…

…which was originally drawn on my old Amiga 1200 ‘030 with Deluxe Paint 4 over a decade ago which doesn’t make me feel old in the slightest of course. The intention was to release a small demo written in Blitz 2D with all of the effects running on the monitor’s screen, but I didn’t get much of that code written. What I’m thinking of doing is reworking the background, expanding the image to 16:9 ratio and using it as the basis for a video thumbnail for YouTube because I reckon that’d look nice.

A lot of other interesting files have been found including a couple that I needed for a future blog post and some game graphics which might have to be rolled into a little potential project I was messing around with earlier this evening whilst procrastinating… I’m not sure if what I’m trying to do is actually viable right now so the whole thing might not be going anywhere and I’ll therefore remain annoyingly cryptic about it for the foreseeable future.

Workprint – March 2018

So let’s get some workprint business out of the way first; since there are now two people showing an interest in converting Vallation to other platforms I might just have to properly shuffle it to the front burner and get on with building the new levels so they actually have a full game to convert. This process will doubtless involve lots of expletives – all aimed at myself for taking shortcuts or bodging – and possibly some rewriting or at least refactoring of the code because it seems to take far more processing time than I remember.

The RLE-based background compression I was mumbling about in the last update is also implemented and works surprisingly well, in fact there’s a simple but functionally complete game wrapped around it now. It has over 56K of background data in there which has been compressed into a mere 23.1K and takes around six minutes to scroll through at one pixel a frame. My intention is to get the entire game done rather than doing a “development diary” so I know it’s finished when writing the C64CD blog posts.

I’ve done a few more tests as regards grabbing video footage, again using VICE and OBS to this time accidentally record a full ten level playthrough of Warhawk. The results look quite solid, but there’s a bit more fiddling with settings I want to do and I have Vegas Pro courtesy of the Humble Bundle to install and get my head around… so who knows, perhaps I’ll become a rich and famous YouTuber? Well okay, probably just a YouTuber but I’m only doing it for the groupies anyway.

In other news, whilst I was away in Kent I met up with fellow Cosine inmates Darren Nevell , Frank Gasking and Sean Connolly for the twice-yearly internal meeting; that makes things sound all official and stuff, but we basically take up a corner of Starbucks and natter for the best part of a day. After nursing a coffee each for a couple of hours we then piled into Level Up and spent a happy hour or so trying to persuade ourselves not to buy everything in sight! Amongst other things I ended up with a PSU for one of my spare Atari 800XLs, a collection of books which are destined for the racking going into my office once it’s decorated including one about BASIC for the Dragon 32, an unboxed freebie of A64 – a C64 emulator for the Amiga which has a dongle for connecting peripherals – and… well, this thing:

Despite looking like an adolescent Enigma machine it’s actually a joystick interface for the Spectrum where each direction and the fire buttons can be connected to keys so pushing left on the stick is, as far as the computer is concerned, someone holding down the O key. I absolutely adore the bizarre but functional nature of this thing; it’s such a perverse work-around for the problem but at the same time will literally work on anything that doesn’t require actual typing to play. Come to think of it, you could also “type” rude words with the joystick…
