I have changed it to load the system messages into an array ...

Re: New adventure game and BASIC framework (don’t expect a new Ravenswood)

As a guide without adventure specific code the program is about 5.2K and with the verbs etc. loaded for the Ransom adventure there is about 2.2K of heap used by variables / data.
I make that about 17K free for user code and additional verbs etc. on a beeb model B with DFS in mode 7.

Re: New adventure game and BASIC framework (don’t expect a new Ravenswood)

I have changed it to load the system messages into an array rather than on demand every time. This takes up an extra 300 to 400 bytes (mostly for the messages array) but any actions using them are now significantly faster, e.g. TAKE LAMP is more or less instant, while LIGHT LAMP (which still loads a...

Thanks for reminding me about that. Someone did mention it before and I had already forgotten!

The beeb speaker often has background noise. I suspect one of the technical people on here can tell you how to sort it - I believe you need to solder a resistor somewhere. For loading and saving I have just ordered two of these:- http://stardot.org.uk/forums/viewtopic.php?f=8&t=12689&start=30

I have spent additional time looking at where it is slow and while it is down to the conditions it is not down to quantity of them so much as the functions they call when activated so I think this while thing may still be reasonable in BASIC.

Thanks. Some of it will definitely need to be relaced with machine code, specifically the parser first - that is the slowest part. Packing will help a little and I will give it go.

Done. Change Q% on line 30 from 1 to 0 to re-enable CLS on change. I may have to do it properly with a command like CLS ON and CLS OFF etc.

I have also added SAVE and LOAD. They seem to work! :shock:

That mostly leaves carry weight and a lot of work on the spreadsheet...
