I’m trying to come up with a way that I can make an interactive animation that first takes x and y coordinate inputs from the user via something like a text box and then uses them in several array and matrix operations.
My second option is to build the input system in a way that a 20x20 coordinate system is visible and the user selects the points by clicking on them. I still need to record the coordinates users clicked to do further matrix operations on them, though.
