for(rx=-1; rx<2; rx++) <br /> for(ry=-1; ry<2; ry++) <br />'This code simply means “any particle touching a heater particle”.' I probably sound like a moron but how do those numbers, letters and symbols work out into “any particle touching a heater particle”. I'm not actually stupid so i'll make an attempt to understand any explanation given, but i don't really get any part of step 4 on this page (https://powdertoy.co.uk/Wiki.html?id=coding-tutorial).
Essentially. rx starts at -1 The for loop will execute the body while rx is less than 2. each execution of the body rx increases by 1. (The same happens for ry)
it still won't show on any powder toy windows though. sorry about this, i saw gamerboy8864's video and he looks around my age so i thought i'd try modding. actually it says the system cannot find the file specified and it can't start the program
