There is a lot of good info around on calculating parabolas and the like, but I can't seem to apply it to my specific situation.
Basically, I have two sprites (start & end). I want them to be connected by a loosely hanging wire type of thing.
and I'm not using physics. or plugins.
so basically, I want to draw a droopy line from (start.x,start.y) to (end.x,end.y).
I'd also like to be able to change the length (and thus, the droopiness) of the line.
I'm sure this isn't hard. But my brain just isn't doing it.
