Microsoft has open source’d GW BASIC, originally released in 1983. You can browse the source here on GitHub, but the article looking back at what was also going in in tech in 1983 is also a fascinating look back in history.
BASIC 10Liner 2017 contest results
My first attempt at writing and submitting an entry in the BASIC 10Liner game contest and I placed 18/19. Not bad for my first try!
BASIC 10liner 2017 contest entry – Boulder Jumper
I’ve seen posts about the BASIC 10Liner contest before, but this time I spotted posts for the 2017 contest with time to put an entry together. This weekend I spent a few hours putting together an entry using Sinclair BASIC on an emulated Spectrum, using Fuse for MacOS.
My entry is a take on the infinite runner style games, like Temple Run, but re-imagined in glorious 8 bit Sinclair BASIC style, I’ve called it ‘Boulder Jumper’.
If that’s not enough I went completely retro and implemented the graphics using only characters. This is my first entry to the BASIC 10Liner contest, and the first time I’ve written any Sinclair BASIC for maybe 33 or maybe more years.
My first thoughts were how can you possibly write a fully functioning game in 10 lines of code, but you can have multiple statements per line, and enter in either the 80 chars, 120, or 256 characters per line category. I think I’m just about squeezing into 120 per line.
Here’s a screenshot of the awesome gameplay:
Your character is a ‘b’ character, and rocks come from the right moving to the left, as ‘o’ characters. You press ‘m’ to jump and jump over the rocks or get squashed. You get points per rock you jump over, and have 3 lives.
Here’s the code in all it’s Sinclar BASIC glory:
And here’s the 10 lines in the Fuse emulator:
It’s not great and you could do a lot better (this is probably better suited to a ZX-81 than the ZX Spectrum), but it’s my first attempt for the 10Lines contest, and I had run writing and playing it!
