When I play Pong, I don't really pay attention to whether my mouse is in
the Pong window. That means that sometimes, annoyingly, the window loses
my mouse, and I lose control of the paddle. Gasp! D:
This commit teaches Pong the wonders of global mouse tracking, thus
enabling the player to focus solely on the game.
This application was including, opening and unveiling the path for
a config file, however it never actually reads or saves anything
from the configuration file.
Since it's easy enough to add it back later if needed, probably
makes sense to remove the unused code right now?
Problem:
- `static` variables consume memory and sometimes are less
optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
every time the function is run.
Solution:
- If a global `static` variable is only used in a single function then
move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
`constexpr`.
Just because you're the player, doesn't mean you can cheat ;)
- Limit paddle speed when following mouse cursor.
- Unhide pointer -- can't grab it, can't see when it's about to leave
the window otherwise.
- Add last pointer y position indication for the player paddle.
- Prevent the paddle from following the mouse when Up or Down is being
held (avoid controls fighting).
Player 1's score used to be score's width offset to the right. Now it's
score_margin away from the divider line, same as player 2's.
Also factored out score margin and increased it from 2px to 5px just
to make it look a little nicer.
