Quote from: DJ Omnimaga on May 12, 2015, 10:06:41 PMWith this one (and actually, most programs I write), I really wanted to challenge myself. I want it to be in pure BASIC, and need as few extra files and subprograms as possible. Same with that pi program. I'm not sure how it'll exactly work (unless you can stand a full wash of black before the game begins...actually, I'll be right back)
Wouldn't spaces work? With text(-1, two spaces are like 12x8 pixels large and it makes an entire rectangle white. Then the black 8xi file can be used to erase them. That said, having to redraw everything might still slow things down.
Otherwise you could use xLIB or DCS7 rectangle command, unless your goal was to absolutely make the game pure basic.
