Challenges for update-player

Referenced from lesson Player Animation (Spring, 2021)

For each of the challenges below, see if you can come up with two EXAMPLEs of how it should work!

1 Warping - Program one key to "warp" the player to a set location, such as the center of the screen.

examples:
  update-player(                 ) is

  update-player(                 ) is
end

2 Boundaries - Change update-player such that PLAYER cannot move off the top or bottom of the screen.

examples:
  update-player(                 ) is

  update-player(                 ) is
end

3 Wrapping - Add code to update-player such that when PLAYER moves to the top of the screen, it reappears at the bottom, and vice versa.

examples:
  update-player(                 ) is

  update-player(                 ) is
end

4 Hiding - Add a key that will make PLAYER seem to disappear, and reappear when the same key is pressed again.

examples:
  update-player(                 ) is

  update-player(                 ) is
end
