Behaviour.isActiveAndEnabled

Description

Checks whether a component is enabled, attached to a GameObject that is active in the hierarchy, and the component's OnEnable has been called.

Behaviour.isActiveAndEnabled returns true only if all the following conditions are met:

• The GameObject that the Behaviour is attached to is active in the hierarchy (GameObject.activeInHierarchy == true).
• The Behaviour is enabled (Behaviour.enabled == true).
• The component's MonoBehaviour.OnEnable method has been called.

Important: Even if a component is enabled and its GameObject is active, isActiveAndEnabled still returns false until OnEnable is called on the component. This is by design in Unity's scripting lifecyle. For more information, refer to Event function execution order in the User Manual.

public class Example : MonoBehaviour
{
    public Image pauseMenu;

    public void Update()
    {
        //Checks if the GameObject and Image are active and enabled.
        if (pauseMenu.isActiveAndEnabled)
        {
            //If the Image is enabled, print "Enabled" in the console. Stops when the image or GameObject is disabled.
            Debug.Log("Enabled");
        }
    }
