Its a somewhat glitchy tri filler! drag the points! the 3 corner points are the x/y difference, and the center one is the x and y or the shape. has nobody ever thought of this before? very compact in under 100 blocks and 1 var! it glitches a bit, and won't work for every triangle. Check out my rec filler too! (also by me) https://scratch.mit.edu/projects/556223303/
all by me (incuding idea)
