Using AddComponent which adds a new component instead of getting one.

Using FindObjectOfType which searches the whole scene.

    Button btn = GetComponent<Button>();

Common Mistakes

Using 'enabled' instead of 'interactable' to disable the button.

Using Debug.print which does not exist.

The interactable property disables the button interaction. Debug.Log prints a message to the console.

5fill in blank

Fill all three blanks to add a button listener in Start and define the click function that changes button text.

Unity

public Button myButton;
public Text buttonText;

void Start() {
    myButton.onClick.[1](OnClick);
}

void [2]() {
    buttonText.[3] = "Clicked!";
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using wrong function names that don't match the listener.

Trying to set buttonText.text without referencing the correct property.

Use AddListener to add the click event. The function name is OnClick. The button text is changed by setting the text property.
