Simple bouncing ball algorithm
Made some more progress on my DS coding. Po_Ng now has two bats and a ball. The ball bounces around the screen using this absurdly simple bit of code:
if (xpos < 0 || xpos >= 256) xv *= -1; if (ypos < 0 || ypos >= 192) yv *= -1; xpos += xv; ypos += yv;
Yeah, making stuff bounce around the screen is that simple 
So simple I had to use Google to find out how…
Tomorrow I make it bounce off the bats too.
