Its all in the Algorithms…
Often before any coding begins, I would transfer the plan in my head about just how things worked down onto paper. Sometimes I needed paper to draw up visuals, or to scribble bench tests for code to make sure that the numbers would add up/work.
This I recently dug up, a plan for writing a centipede arcade game clone on the ZX Spectrum. All the algorithms and concepts were in place, as well as a couple of pages of Z80 Assembler at the end. I even dug up the original source file on tape for this (called “Armourpede” (its what it says at the top when loaded in ZEUS assembler)) and from memory I seem to recall that this is all about animating a centipede on screen… (Hmmm, now I’m going to have to review it and test it)
Its how games would start (including the many old basic games from many years prior) – however not all game designs were written as neatly in books, but instead a variety of loose bits of paper that will have been lost over time.
