There we go! And to think that the the whole problem of yesterday was a a wrong minus signal. Or rather, a wrong approach to the problem The problem was that I was checking which of the given start and end points was greater, then doing a different order in the subtraction. I was doing this if start > end: x = start - end; if end > start: x = end - start; When all I needed was this: x = start - end; Simply because I don't need to know the positive, natural value of the difference between the points, which was what I was worried about, I just needed to get the result. Example: starting at -20 and going to -10, x would be +10 in the first case, or -10 in the second. In that first case, I would also have to multiply the result by -1 before dividing by number of interpolation steps. Next up, I plan on stopping at arbitrary between points, creating a very smooth face turning animation that can stop at any angle. Messing with eyes and mouth in those cases will prove challenging ANYWAY, I probably won't work much on this for the next couple of days as I scored a side gig with a deadline for monday. #programming #gamedev #raylib #nim
