Re: Reducing Basic Program Size

I'm currently setting PAGE to &1100 when running the main game file - the first file displays the instructions, and has page set at &1900. I'm assuming a BBC DFS system. If I could, I would relocate page to &E00, but when the game is over, a third part is loaded containing your verdict, which needs ...

Re: Reducing Basic Program Size

Thanks, I'm getting confused. &E00 is where DFS starts. My screen data has some repetition - the top and bottom lines of each level are always filled in, and are therefore not necessary. This will shave some data off. I'll keep stabbing away at this. bbcmicro.co.uk is immensely useful for this type ...

Re: Reducing Basic Program Size

Thanks Lurkio. Looks like I can use &A00 (1300 or &514 bytes) takes me into &E08, which I think is ok. This old game - Gold Mine - http://bbcmicro.co.uk//game.php?id=1590 - uses some data file loaded into &2200. The BASIC code then pokes at this memory location to grab the level layout. I can always...

Re: Reducing Basic Program Size

I wanted to pick up further on a point made with regards to storing DATA statements into a memory location. My Androidz game has 20 levels of compressed level data. Each level occupies 65 bytes. How would I go about pushing this into a given location, .e.g. &A00, and keep it in memory once I load th...

In short, the described behaviour of the magnet is incorrect. It has no affect on moving chests, only Up blocks are affected by it's movement. Thanks for looking into this.

Re: Using a Mac or PC for BBC games authoring

Well done with building BeebAsm locally and creating SSDs! BeebVSC is great (I have it installed) but yes, it's more for assembler than BASIC. In the end, I didn't use BeebVSC's 'build' and 'run' features. Instead I just used Visual Studio Code's 'tasks' feature. I created some simple script files ...

Re: Using a Mac or PC for BBC games authoring

The -boot option unfortunately defaults to performing a *RUN, which is no use for a Basic file. I did create a blank template SSD, containing a manually made !Boot file with the CHAIN"DROID1" in it. However, running the above command overwrites everything, which is a shame. I think you can work aro...

Re: Using a Mac or PC for BBC games authoring

FWIW, I think it would generally be useful if SDLIDE could output Acorn-format tokenised BBC BASIC programs that are compatible with at least a BBC Micro Model B. I don't think there's any technical difficulty with that, but having saved to an Acorn-format (pre-BASIC V) tokenised file what does one...

Re: Using a Mac or PC for BBC games authoring

By the way, if what you want to do is create a BASIC program in a text editor and then run it under emulation, one way might be to use BeebAsm to create SSD files which contain the tokenised BASIC program and are already set up to auto-boot and run that program. You could then edit your BASIC files...
