Re: printing to the screen without using rom calls
when you say call plot, do u mean the plot rom routine? Any plot routine will do, there's even one in the book. But if you want to have at look at this one, it plots OVER 1 at the position in DE = (y,x) where (0,0) refers to the top-left corner of the screen. Plot: ; plot over 1 at de=(y,x) ; chang...

Re: BASin - How to load code from assembler?
These are uncompressed data? Yes, 70 fullscreens with 6912 bytes and 70 dithered versions with 6144 bytes. Due to the 16:9 aspect mode, 48 lines of data are thrown into the bin. The BASin profiler shows that it takes 2.8 frames for two LOAD operations. So it gets to about 230 Kb/s. I am reading doc...

Re: BASin - How to load code from assembler?
Here's a warp effect that uses the file access feature from BASin. Currently a small Basic prog that LOADs the frames one by one and a small USR routine to throw the bytes onto the screen. The crisp effect is caused by loading the coloured frame directly followed by the dithered version of the same ...

Re: Guess the screen$
Here's the palette from Fuse. And below, the same pic in ZX Paintbrush. I think Paintbrush is more accurate. Notice how blue and bright-blue hardly differ? In Fuse the contrast is somewhat cranked up beyond what's true on a CRT I think. And the non-bright red comes out as fox brown. :? https://i.pos...

I did a few titles from Hebdogiciel mags but when I try to generate the request there's a popup "Original = Yes must be specified only once!". No idea what's causing this.

Re: Simple path finding algorithm in assembler
I know that I'm several days late on this subject with answers that are going to be superior to mine, but I would like to say that for my game F'n Balls, I used the Wavefront algorithm for my pathfinding needs. It ran quite quickly and took a nominal amount of memory to implement. I write about it ...

Re: jump if signed 16-bit number is >0, <=0, fastest code
but than it is slower than 24ts case. 4*5+10=30. might be useful if HL cannot be destroyed, though. but then we have 18/32 version, which is not much slower, and sometimes faster. still, might be useful for stable timings. Yes, and maybe A is already 0 from a previous operation which would allow us...
