Thank you! I wonder if other Stardotters are participating...

Thanks Lee!

Nice game and well thought out logic such as a little randomness to prevent ball getting stuck horizontally Cracked 1k points

Couple of bytes you could reclaim with unused variables ME$ and YEAR

Thanks! I see you have read the source code well

Need to finish the accompanying required documentation!

I had a quick play with getting the game to work on BBC Basic for SDL (attached). You'll need to rename it to OUTBREA.bbc. It was interesting as the centre of the "O" character is not in the centre of the "O" on this version of BBC Basic so the collision detection didn't work. What I did to get around this was define char 224 an O character to match the BBC Micro O.

I really take my hat off to you - the game is ingenious, and it's only when you try and take something like this to bits you realise just how clever it is.

Thanks! And great to see what is basically the reverse process of me getting the game down to 10 (short) lines of BASIC
You even spotted the statement that I removed in the final version (ball_y=5). It is indeed unneccesary.

One of the most interesting things I found in your listing was how you had to move some bits of code out of what might be the most obvious order to put them in, so that you could keep the lines within the character limit. It's a really remarkable little program!

Very impressive game coding
Hope it wins!!

Characters are 7 pixels wide in an 8-pixel-wide cell. I think the original BBC Micro's characters were 'right justified', i.e. they have a gap on the left but not on the right. I chose to make mine 'left-justified', with the gap on the right, so they are shifted left by one pixel. I think the main reason was to demonstrate that I had not simply reproduced the BBC Micro's character set, which is protected by Copyright.

Copyright is already a tricky issue for emulators, so using the original Acorn character set probably isn't a big deal for them. But in the case of BBC BASIC for Windows and BBC BASIC for SDL 2.0 I needed to be ultra careful in respect of IPR. Whether in practice the one-pixel shift helps I don't know, but it shows I thought about the issue.

Thank you! I'm pretty proud of my 4th place in the PUR-80 category

You woz robbed!

Seriously, though, Outbreak is fantastic!

Incidentally, The Children, which won the "EXTREM-256" category is another cracking little game (once you get the convoluted emulation setup right!). Would be great to see a Beeb port of it...

[0xC0DE]

Honestly, I haven't looked at many of the other programs. There is a lot to learn from these for sure!
