Button appears when switching between scenes or quitting game
Scenario:
There are two Scenes - Scene A and B.
In Scene A there is a Watch Ad Reward Button with the below button cool down script.
Then user clicked Watch ad reward button. The button disappears. (I have set button to appear again after 1 hour).
When I go to Scene B and back to Scene A the button get appeared, also when quit the game. (So there is no point of 1 hour timer to appear the button).
What I need here is the button need to appear after 1 hour even when user switching between scene A and B or quit and restarting the game.

void Awake()
{
// Get a reference to your button
myButton = GetComponent<Button>();
if (myButton != null)
{
// Listen to its onClick event
myButton.onClick.AddListener(OnButtonClick);
}
}
// This method is called whenever myButton is pressed
void OnButtonClick()
{
StartCoroutine(Cooldown());
}
// Coroutine that will deactivate and reactivate the button
IEnumerator Cooldown()
{
// Deactivate myButton
myButton.interactable = false;
// Wait for cooldown duration
yield return new WaitForSeconds(cooldownDuration);
// Reactivate myButton
myButton.interactable = true;
}
}
Here is a version of @dharmesh_b script that will use PlayerPrefs to save and reload the countdown timer.
