I removed a print statement that printed out every position of the ball, because it was no longer necessary.
I also added code to clear the background before drawing to the screen at the start of the game, to remove
any lingering un-erased objects. Finally, and most substantially, I finished the initial implementation of
the client-side GUI. The client should now be able to specify a connect code through the GUI, and connect
to the appropriate server.
I moved the GameType struct (and the Mode enum) to a separate file, as I will need
to use it in the check_server and check_client functions as well. I also added the
signum function (which was previously in sign.hpp) to this file, since it was the only
function in sign.hpp. Finally, I added a check, that will only display the GUI, if the
user didn't provide any command-line arguments.
I added code to display a help text after the user selects a mode. Currently,
this text is only displayed in single player mode. Additionally, I added a rudimentary
'form' to input IP address and port, if the user selects server mode.
The most important addition is that the program now parses data in the
Serial_Data struct, and updates the positions accordingly. I also removed
the old implementation with strings, and fixed a bunch of bugs along the way.
Specifically, I added code to send a message from the client, after the client is launched. This message is used to try to connect to the server. Once the server receives this message, it responds back. After the client receives this response, the connection has been established, and the game can begin.
I also added code to wait (on the client side) for the server to press the spacebar.
The agnostic struct consists of a 'Mode' enum, and a 'Sock' type. The
'Sock' can be either a Server or Client, depending on the type of game.
This allows polymorphism, as I don't have to worry about whether the game
is being run in Server or Client mode, and I can call the same methods regardless.
