Just catching up with these, brings back memories of my early teens spending warm summer days indoors trying to write a version of Bomb Jack in BBC Basic

[@ColinHoad]

I spent plenty of sunny days indoors in a similar fashion when I was growing up... and probably still do 😅

Great stuff!!

[@ColinHoad]

Ah, thanks Steve! I wasn't sure if these videos would find favour with my regular viewers of the games review series, really pleased to see you're finding them interesting as well 😄

Not long found your channel - slight error in your explanation. The % after a variable name just means integer variable as, by default, a variable that holds a number would be a floating point variable. The reason behind specifying integer variables is because it's slightly faster than floating point and in something like a game speed is essential. Also, there's a second way to use REM and that's with a star command: *| which in mode 7 appears as *||

[@ColinHoad]

Thanks, those are both very helpful corrections / extensions on what I covered 😀

[@YesiPleb]

@@ColinHoad Just bear in mind that REM can be tokenised to one character whereas *| will be two characters so if one is running out of memory, REM would be the better option.

I didn't think REM did anything either... and then I saw submissions to BBCmicrobot that drew planets with one REM statement and one CALL PAGE+5 statement (or something like that). But yes in BASIC at least they don't do anything :D

[@ColinHoad]

I've not seen REM used for generating planets before! 😄 Will have to check out the bbcmicrobot archives...
