Re: Plasma Squares

Well, I use Spectaculator generally, as I like it. But, that only saves rzx files. Spin however can save an animated gif. So, I make a snapshot in spectaculator, and load onto Spin. It does fail quite often, but if anyone’s a better solution then I’m all ears!

Re: Plasma Squares

Ahhhhhh, now then, it works better when we reduce the separation span in the plasma data;

Re: Plasma Squares

Glad you like it, but I still think 50% faster would give a more fluid feel to it.

Still fiddling to try and squeeze more speed out of it though.

Re: Using TR-DOS software on real hardware +2e, DIVMMC

Yes, indeed, its just a disk system really, however its lack of popularity in the UK means that most stuff available in the TRD format is likely to be of Russian origin. It is only timings with Demos etc that suffer

Re: Using TR-DOS software on real hardware +2e, DIVMMC

As long as the DivMMC is running ESXdos as its system, then yes, TR-DOS calls are supported. Its just timing issues with running certain things that will still cause issues, as the Pentagon and Scorpion don't have contended memory as far as I know. I also have a +2e sitting on a shelf gathering dust...

Re: Plasma Squares

This demonstrates the slow and clunky look of the character square version;

I've just about optimized the core of it about as much as possible and its still a bit too pedestrian in my opinion

Re: Plasma Squares

Would be good to see an example of such a thing, though that sounds like a rather more complex animal than I'm used to producing. Incidentally, I made a version of this one that works on character squares, 768 of them, but its crap! Its far too slow, even with unrolled loops. I've a little work stil...

Re: Plasma Squares

I'm also happy that my explanation managed to convey the mechanics of it in a clear enough way. I'm trying to work on a Screen Clear version, but the attributes are making it look clumsy. I'm also planning the plasma creator and perhaps a version that creates plasma based upon some random values, th...

Re: Plasma Squares

Another example, using one of RedBalloons Lovely creations For one of Einars Games (I think?)

Benefits from being mono and heavy on the pixels side of things.

Re: Plasma Squares

At a very basic level; the 192 bytes of the plasma table relate to 192 (2x2) blocks that the screen gets divided into (16 x 12) Each plasma byte is checked and incremented upon each pass through the routine. Once the byte is within the range 00-07 then the square is 'active'. Being active means that...
