Re: Drawing lines - BASIC vs machine code

That's very good actually! It's an impressive 3D effect for so little code. I have to admit I was pretty encouraged to pursue the idea once I saw it running, but was worried about how slow it would become in pure BASIC once all the logic was in place. One optimisation I can spot straight away is th...

Re: Drawing lines - BASIC vs machine code

I suppose I'd better give the full details as it seems there are all sorts of angles I haven't thought of. Basically I started by wondering about "bringing Deathchase for the ZX Spectrum to the BBC": https://www.youtube.com/watch?v=djHoBBrtzKY I like the very simple concept. Just dodging t...

Re: Drawing lines - BASIC vs machine code

Sounds like a good plan. What you should do next is define exactly what you want, ie: - Do you need to be able to draw lines at all 160 x-positions? - What heights of lines do you need, and again do you need to cater for the full range of 256 pixels? - What colours are required? - What happens to t...

Re: Drawing lines - BASIC vs machine code

Thanks people, lots of interesting thoughts and tests there! My 2c... 1) Basic uses generic drawing routines, so every time you make a call to the line drawing routine it has to go through initialisation, work out X,Y coordinates relative to the character based screen memory, then plot the all pixel...

Drawing lines - BASIC vs machine code

Some questions about drawing lines on the BBC micro: 1) If I were to execute in BASIC something like this, to draw a vertical line in the bottom left corner: MOVE 0,0: DRAW 0,100 Am I right in assuming that there is little speed benefit in trying to do that in assembler instead? Because mostly what ...

I've had a thing about this game ever since I stumbled across it a few weeks ago.

For those who don't know the game, he's...
