This project visualizes how a sprite moving with the "if on edge, bounce" block moves. Follow instructions in the project. Press s to change the volume of the pops the block makes when it hits the edge of the stage. Some recommended direction inputs (turbo mode suggested for the full effects): 53.9: Makes the cube not only perfectly hit the corner but also make a perfect grid. 42: Makes the cube always stay on the same path and never fill the whole stage. 24: Creates another interesting grid pattern. 0.01: Makes the cube slowly fill up the right side of the grid. Turbo mode is necessary for this one otherwise you'll be here all day! 15 (credit to @abubriski for finding this one): Creates an interesting pattern at the bottom and top edges.
Everything is by me.
