The ButtonClicked script is a simple Unity MonoBehaviour class that demonstrates how to interact with UI elements using the TextMeshProUGUI component. Let's break down what this script does:

• Purpose: To display a message when a button is clicked.
• Components Used:
  • TextMeshProUGUI: A component for rendering text in Unity's UI.
  • Button (not shown in the script): The UI button that triggers the DisplayMessage method.

1. Namespace and Using Statements:

   • The script starts with necessary using statements to import required namespaces.

2. Fields:

   • private TextMeshProUGUI TextMeshPro;: A private field to hold a reference to the TextMeshProUGUI component attached to the same game object.

3. Start Method:

   • void Start(): Called once when the script starts.
   • Initializes TextMeshPro by getting the component from the same game object.

4. Update Method:

   • void Update(): Called once per frame.
   • Currently empty (no code inside).

5. DisplayMessage Method:

   • public void DisplayMessage(): A custom method.
   • Sets the text of the TextMeshPro component to "Button Clicked!" when called (presumably triggered by a button click).

1. Attach this script to a game object with a TextMeshProUGUI component.
2. Create a UI button (not shown in the script) that calls the DisplayMessage method when clicked.
