Ok so I got s'more progress. I tried writing the algorithm that places the line points, but it doesn't seem to be doing anything. I have a hunch that it is because of the "pick" command, because I don't really know how to use that. Please let me know if you see any potential bugs (the code runs when the player moves into a blue area, changing the point to red and thus updating the line. also, the bottom 2 lines are copy pasted and altered beneath the screenshot so it also checks and places above, below, and down, in theory at least.)
