Pausing the game

To get the game to pause correctly, we will tweak some scripts we've written previously using the following steps:

1. Open the PlayerBehaviour script and add the code highlighted in bold to the FixedUpdate function:

/// <summary>
/// FixedUpdate is called at a fixed framerate and is a prime place
    /// to put
/// Anything based on time.
/// </summary>
void FixedUpdate()
{
    // If the game is paused, don't do anything
    if (PauseScreenBehaviour.paused)
    {
        return;
    }

    // Check if we're moving to the side 
    var horizontalSpeed = Input.GetAxis("Horizontal") * dodgeSpeed;

    // Rest of FixedUpdate function...

The added code makes it so that if the game is paused, we will not do anything within the function.

2. We then also need to add the same script to the top of the Update function as well:

/// <summary> 
/// Update is called once per frame
/// </summary> 
private void Update()
{
    // If the game is paused, don...
