7.2 Adding Interactivity: Buttons, Sliders, and Input Fields

Interactive UI elements improve player engagement and control.

Step 1: Buttons

• Add buttons to trigger game events (e.g., starting a game or pausing).
• Assign a function to the button’s OnClick event in the Unity Inspector.

Step 2: Sliders

• Use sliders for settings like volume or brightness.
• Link the slider’s value to a script for real-time adjustments:

public Slider volumeSlider;
public AudioSource audioSource;

void Start() {
    volumeSlider.onValueChanged.AddListener((value) => {
        audioSource.volume = value;
    });
}

Step 3: Input Fields

• Add input fields for text entry (e.g., entering a player name or setting game parameters).
• Access the entered text via a script:

public InputField playerNameInput;

public void StartGame() {
    Debug.Log("Player Name: " + playerNameInput.text);
}

Activity: Create a settings menu with buttons, sliders, and input fields for customizable gameplay options.
