Thank you for being so frank. This will be my last ever post to this group.

What sarcasm? None was intended. I would reiterate my forum signature: "I am suffering from 'cognitive decline' and depression. If you have a comment about the style or tone of this message please rep

What precisely do you mean by "does not work"? That's such a vague description it's hard to give advice. One observation is that the code, as listed above, does no checking of return values. For examp

As far as OOP is concerned, your attitude to BBC BASIC will probably depend on which side of the 'debate' you are on. If you consider the essence of OOP to be Classes and Objects, then the 'classlib'

That of course raises the question: why switch to Java rather than continuing to use BBC BASIC on the MacBook? As I mentioned in my previous reply, BBC BASIC's multi-platform support is one of its gre

Has anybody been in contact with Andy recently? My emails to him aren't being answered so I'm a little concerned.

I've released version 1.22a of BBC BASIC for SDL 2.0 - the cross-platform programming language for Windows, MacOS, Linux, Raspberry Pi OS, Android, iOS and in-browser. The changes in this version are

Remember that as well as the built-in graphics statements (MOVE, DRAW, PLOT etc.) BBC BASIC provides an easy route into Anti-aliased graphics, OpenGL (3D) graphics and Shader graphics. Using the suppl

According to the linked article, "Platforms such as those only providing payment processing ... are excluded from the deemed supplier provision". My understanding is that PayPal fall into this categor

BBC BASIC for Windows is a paid-for product for 'historical' reasons only, and the income it generates is negligible; I certainly do not want or need 'donations'. However it isn't a trivial matter to

Further details of how things are changing on 1st July can be found here. I had hoped that PayLoadz, who provide the download of BBC BASIC for Windows, would look after the collection and reporting of

Not exactly. As with the Shove Ha'penny suggestion 'vertical' friction (in your case the friction between the wheels of the dodgem cars and the floor) is crucial to the operation, but that cannot be m

Update: it appears that Firefox Nightly for Android now supports WebAssembly Threads. So that provides an alternative to Chrome for those who want to run BBC BASIC in-browser on an Android device. The

Yes and no. Box2D cannot accurately reproduce the 'rolling friction' of the ball against the cloth, because that involves the third dimension, but it certainly can take account of the friction between

I now know more about Shove Ha'penny than I did before (not difficult). If I've understood correctly it relies crucially on friction between the coin and the surface on which it is sliding, but that f

That should be achievable with Box2D, but probably suits a pure 2D approach (like most of the existing Box2D demos). I don't think that the introduction of a 3rd dimension into the rendering (which is

I don't know the first thing about it, I'm probably from the wrong part of the country, but I'm not averse to educating the world in the weird ways of the British! I'll see what a web-search reveals.

Thanks, but I still think 'a little bit of knowledge can be a dangerous thing'. If one approaches structures (and arrays of structures) from a 'high level' viewpoint, bearing in mind that one of their

When I recently wrote the Pinball program I came to the conclusion that it was probably the only 'interesting' (read 'interactive') example of applying 2D physics to a 3D system. Being an inclined pla

Just to add, I notice that the documentation does use the word header when it means heap entry (or record or whatever you choose to call it). That's a typo: clearly a 'header' is something that immedi
