Changing TextMeshPro Text which is child of 2D Sprite via script in Unity

Question

I have a 2D square object sprite that has a child TextMeshPro object which stores a number.

Hierarchy in Unity:

Unity Scene:

I want to dynamically change the number in the TextMeshPro object via a script that is a component of the 2D square object. Below is the code I'm using.

'''

[SerializeField] private TextMeshProUGUI m_playerText;

// Start is called before the first frame update
void Start()
{
    m_playerText.text = "8";
}

'''

However I am getting the error "NullReferenceException: Object reference not set to an instance of an object"

Would appreciate any feedback to solve this.

Use GetComponentInChildren<TextMeshProUGUI>() for solve the problem:

void Start()
{
    m_playerText = GetComponentInChildren<TextMeshProUGUI>();
    m_playerText.text = "some text...";
}

Do you mean to drag and drop onto the inspector tab of the player object? – Abhishek Venkatesh May 28 '22 at 09:31
