Code a slider widget from scratch. It’s okay to ignore the changing color of the slider track, but in general feel free to use color and change the size of everything!
HINT: the dist( ) and constrain( ) functions will help. No cheating. :)
Step 1. set up the canvas. Sliders are generally small, and longer than they are tall (or vice versa)
Step 2: Set up the slider bar and the dot.
Okay, I got to the point where I want to click the dot to move, but now I'm stuck because I want the dot to always be visible, not just when mouseIsPressed.
Okay, I figured out how to move the dot with the mouse, but now I need to figure out how to make it stay at the mouse position when the cursor is released...
