Re: Source code for old BBC Micro games

Kevin Edwards recently released the source code for his BBC Micro game 'Galaforce':

https://stardot.org.uk/forums/viewtopic.php?f=1&t=16628

It's obviously not applicable to BB4W though, because Galaforce is written in 6502 assembly language.

Can we expect a Disco 3 at some point in the future?
I don't think this forum needs any more of my failed experiments. :D

Re: 1983 program listing

What version of BBC BASIC are you trying to run that program under? If you are trying to run the program under 'BBC BASIC for Windows' or 'BBC BASIC for SDL 2.0' then it couldn't possibly work because their built-in assemblers don't understand 6502 assembly language (the BBC Micro is based on the 65...

As a test, I'm currently putting together a text "adventure" inspired by a long-running thread on syntaxBomb relating to whether the moon landings were a fake...
Moon hoaxers are on the same level as Flat Earthers and Young Earth Creationists.

Best avoided.

Re: The power of GPU shaders

Once I'd found the texture the Clouds demo posed no particular problems, except that it seems to be even more demanding on the GPU than the Seascape! Unusually, I found that trying to record the output - for uploading to YouTube - reduced the frame rate and I ended up having to do it on a faster PC...

there any other examples at ShaderToy that you think would be worth porting to BBCSDL? Having done one it might not be too difficult to do others, but that remains to be seen.
This one looks nice:

Re: The power of GPU shaders

Exercise for the interested (and clever) BBC BASIC user: port this 'Seascape' shader/demo to BBCSDL Here you go! It needs a relatively powerful GPU for full frame rate (and runs extremely slowly on a Raspberry Pi). A complete code listing is below. Brilliant! :D Whilst I'm not getting consistent re...

Re: Code a game comp - The Great Christmas Adventure - Nov 4th to Dec 23rd

That red balloon in the video took about 4 hours to model and texture in Blender! I have seen many Blender videos. I have tried Blender in the past and it is quite the tool. I also tried and bought Hexagon 3D. I am surprised you have become skilled in Blender so quickly. Not skilled, but calmly sle...
