So my last idea didn't work, but then I thought "why not just calculate each next point on the line between those two points"? So simple, so fscking obvious that I literally kicked myself for not thinking of it sooner.
Then came my next problem "how do I graph the next point on the line". I was sure I learned this in h.s. geometry, but since that was awhile ago (and about 3 1/2 years of funtime college ago), I embarked on a mathematical quest to figure out how to graph the next point of the line. So I figure out that I can subtract my destination x from my origin x, and destination y from my origin y, and the resutling numbers give me a rough plot point. Wow. Amazing.
Yea. Considering that every 7th grader learns how to do that under the name "rise over run", or the more technical term "slope", I think I will be encouraging youngsters not to fall asleep in algebra and geometry.
DOH! DOH! DOH!.
