Adjust Popup Logic

Background Knowledge

Popups are a crucial aspect of any interactive application, providing users with essential information and options at the right moment. In our current implementation, popups are handled by instantiating an "empty popup prefab," which allows any popup of any type to be created on the fly. This approach seems to save space and works well in theory. However, it can lead to issues when multiple popups need to be displayed simultaneously.

The Problem with Current Implementation

Let's consider a scenario where a user is modifying a setting in-game and decides to leave the menu while trying to alt-f4 to exit the program. In this situation, two popups would be displayed: one for "are you sure you would like to leave [settings] without saving your changes?" and another for "Are you sure you would like to quit? [the program]". Currently, if this situation were to occur, the first popup, the settings confirmation, would be displayed, and then "overwritten" by the quit game popup. Both would be displayed at once, but the first one would lose all functionality and would be permanently stuck on the screen.

This issue arises because we are using a single variable to hold the instantiated popup, rather than a list to store multiple popups. As a result, when a new popup is created, it overwrites the existing one, causing the first popup to lose its functionality.

The Solution: Using a List for Instantiated Popups

To resolve this issue, we can create a list to store all the instantiated popups. This list would initially have a length of 1, since this is the normal number of popups to be displayed at once. However, when the situation arises where another popup is needed, we can add it to the list, and both popups would be able to be displayed without either losing any functionality.

Here's an example of how we can implement this solution:

Creating a List for Instantiated Popups

// Create a list to store all instantiated popups
List<Popup> popups = new List<Popup>();

// Function to create a new popup and add it to the list
public void CreatePopup(Popup popup)
{
    // Check if the list already has a popup
    if (popups.Count > 0)
    {
        // If the list is not empty, add the new popup to the list
        popups.Add(popup);
    }
    else
    {
        // If the list is empty, set the new popup as the first item in the list
        popups.Add(popup);
    }
}

Displaying Multiple Popups

// Function to display all popups in the list
public void DisplayPopups()
{
    // Iterate through the list of popups and display each one
    foreach (Popup popup in popups)
    {
        // Display the popup
        popup.Display();
    }
}

By using a list to store all instantiated popups, we can efficiently manage multiple popups and ensure that each one retains its functionality. This approach provides a seamless user experience, even in situations where multiple popups need to be displayed simultaneously.

Benefits of Using a List for Instantiated Popups

Using a list to store all instantiated popups offers several benefits, including:

  • Efficient management of multiple popups: By storing all popups in a list, we can easily manage multiple popups and ensure that each one retains its functionality.
  • Seamless user experience: With a list-based approach, we can display multiple popups without any issues, providing a seamless user experience.
  • Improved code organization: Using a list to store popups helps to organize our code, making it easier to maintain and modify.

Q: Why is using a single variable to hold the instantiated popup causing issues?

A: Using a single variable to hold the instantiated popup is causing issues because when a new popup is created, it overwrites the existing one, causing the first popup to lose its functionality. This is because the single variable is being reassigned to the new popup, effectively erasing the previous one.

Q: How does using a list to store all instantiated popups resolve the issue?

A: Using a list to store all instantiated popups resolves the issue by allowing us to add new popups to the list without overwriting the existing ones. This way, each popup retains its functionality, and we can display multiple popups simultaneously without any issues.

Q: How do I implement a list to store all instantiated popups?

A: To implement a list to store all instantiated popups, you can follow these steps:

  1. Create a list to store all popups.
  2. Create a function to create a new popup and add it to the list.
  3. Create a function to display all popups in the list.

Here's an example of how you can implement this:

// Create a list to store all popups
List<Popup> popups = new List<Popup>();

// Function to create a new popup and add it to the list
public void CreatePopup(Popup popup)
{
    // Check if the list already has a popup
    if (popups.Count > 0)
    {
        // If the list is not empty, add the new popup to the list
        popups.Add(popup);
    }
    else
    {
        // If the list is empty, set the new popup as the first item in the list
        popups.Add(popup);
    }
}

// Function to display all popups in the list
public void DisplayPopups()
{
    // Iterate through the list of popups and display each one
    foreach (Popup popup in popups)
    {
        // Display the popup
        popup.Display();
    }
}

Q: What are some common use cases for using a list to store all instantiated popups?

A: Some common use cases for using a list to store all instantiated popups include:

  • Displaying multiple popups simultaneously: When multiple popups need to be displayed at the same time, using a list to store all popups ensures that each one retains its functionality.
  • Managing complex user interactions: In complex user interactions, multipleups may need to be displayed to provide the user with essential information and options.
  • Improving code organization: Using a list to store popups helps to organize our code, making it easier to maintain and modify.

Q: How do I troubleshoot issues with using a list to store all instantiated popups?

A: To troubleshoot issues with using a list to store all instantiated popups, you can follow these steps:

  1. Check the list for errors: Verify that the list is being populated correctly and that there are no errors in the code.
  2. Verify popup functionality: Ensure that each popup is retaining its functionality and that there are no issues with displaying multiple popups.
  3. Review code organization: Check that the code is well-organized and that the list is being used correctly to store all popups.

By following these steps and using a list to store all instantiated popups, you can efficiently manage multiple popups and provide a seamless user experience.
