The TypedWord static variable will reference the complete word being typed as a string; that is, an accumulation of the letters typed, letter by letter, until a word match is found with a zombie or a mistake is made which resets the typing.

The TyperText variable references the Text UI object for displaying the text animation. This variable is automatically assigned in the Awake event. There, the GetComponentInChildren function is called, which searches downwards in the hierarchy for the first matching component. In this way, the text component on the child object can be found. More information on GetComponentinChildren can be found in the Unity online documentation at: https://docs.unity3d.com/ScriptReference/Component.GetComponentInChildren.html.

The variable ThisAS references the AudioSource component on the object. This is needed for playing sounds when keys are pressed.

The ElapsedTime and RecordLettersPerSecond variables are currently place-holders for functionality to be implemented later. They'll determine the fastest typed words and phrases for bonus points and rewards.

The Update function (called once per frame) references the Input.InputString variable to determine which keys, if any, have been pressed since the last update cycle.

All input strings are converted to lowercase to make string matching simpler. This also means Dead Keys is not case-sensitive.

The UpdateTyping event is called when new keys are pressed. This calls the OnTypingChanged.Invoke method, which activates all visually scripted behavior for the typing event inside the object Inspector.

The UpdateTyperText method is responsible for selecting and playing a random attack sound.
