Re: 'Dixel' scrolling... Ghosts 'n' Goblins

Pre-shifting offloads much of the work in a scrolling game to outside of the game loop. For example: You are scrolling from right to left. You draw a column of blocks at the right hand edge of the screen, and then you literally process every single byte in the display - rotating the bits in each byt...

Re: 'Dixel' scrolling... Ghosts 'n' Goblins

The word "Dixel" is indeed a thing and does mean a two-pixel scroll. I never heard of it in the context of the aforesaid game, but it does crop up in a type-in on page 74 of issue 19 of Your Sinclair. Hmm... I suppose it's possible that my addled mind got it mixed up and it wasn't in relation to Gn...

Re: Spectrum namedrops...

Back in 2000ish I discovered that I lived literally round the corner from none other than Woodster, the legendary Speccy emulator coder! I sh*t you not, that was probably the best thing to happen that day.

Re: SpecBAS: Voxel landscape

Yeah, the PNGs (one for the colour data and one for the heightmap) are both 1024x1024. They're loaded into a graphics bank and then PEEK$ transfers the bank's contents to a string. cofs is the memory address of the colour data's string (c$) and hofs is the corresponding heightmap string's first char...

Re: SpecBAS: Voxel landscape

12 lines of code, one of which is a REM. :shock: To be honest, line 120 is only there because I couldn't be arsed to use an END IF. There's no practical limit (well, 2GB of characters and it might get weird to edit) to line length in SpecBAS so it can actually be done in 3 lines. What I need is mor...

SpecBAS: Voxel landscape

Here's my latest adventure in coding in BASIC: https://youtu.be/xln4HuvZpUc And here's the code - you'll need a bleeding edge build from the SVN to run it due to some new commands and a couple of bugfixes that surfaced while making it: 10 REM Voxel landscape. Try changing rz for accuracy/speed trade...

Re: Problem with games not running on Spectaculator

If a program's tape starts with a "Bytes: " header then to get it to run you need to LOAD "" CODE <enter>. That should sort it.

Re: Best Monty Mole game?

I voted for Auf Monty. That was a great game and was truly fun to play, bringing new things to the franchise after a glut of MM/JSW clones of varying quality. It added objects that had to be moved from one place to another, collectables that had noticeable effects when grabbed, great animations, a s...
