Pausing and restarting the game

We will add code so that when the game is first run, it will be in a paused state. The player will then be able to press the Enter key to start the game. Then, the game will run until either the player gets squashed or runs out of time.

At this point, the game will pause once more and wait for the player to press Enter to restart again.

// Variables to control time itself

bool paused = true;
while (window.isOpen())
{

Now, whenever the game is run, we have a variable, paused, that will be true.

Next, we will add another if statement where the expression will check to see whether the Enter key is currently being...
