How to Make Loading UI Wait for Level Data to Finish Loading Before Hiding?

Are you tired of dealing with wonky loading screens that disappear before your level data has finished loading? You’re not alone! In this article, we’ll dive into the world of asynchronous loading and explore the best practices for creating a seamless loading experience. Buckle up, folks!

Understanding the Problem

So, why does this issue occur in the first place? It all comes down to the way our browsers handle asynchronous requests. When you send a request to load level data, the browser sends the request and then continues executing the next lines of code. Meanwhile, the request is still being processed in the background. If your loading UI is set to hide after a certain amount of time or when the request is sent, it will disappear before the data has finished loading, leading to a broken experience.

The Solution: Async/Await to the Rescue!

One of the most popular ways to handle asynchronous requests is by using async/await. This syntax sugar allows you to write asynchronous code that looks and feels like synchronous code. It’s a game-changer!

async function loadLevelData() {
  try {
    const response = await fetch('/level-data');
    const data = await response.json();
    // Do something with the data
  } catch (error) {
    console.error('Error loading level data:', error);
  }
}

In the above example, we’re using the async/await syntax to send a request to load level data. The await keyword tells the browser to pause execution until the promise is resolved or rejected. Once the data is loaded, we can then do something with it.

Implementing the Loading UI

Now that we’ve got our async/await syntax in place, let’s talk about implementing the loading UI. We’ll use a simple HTML structure to display our loading animation and a JavaScript function to toggle its visibility.

<div id="loading-ui">
  <img src="loading-animation.gif" alt="Loading animation">
  <p>Loading level data...</p>
</div>

In our JavaScript code, we’ll create a function to toggle the visibility of the loading UI:

const loadingUI = document.getElementById('loading-ui');

function toggleLoadingUI(visible) {
  loadingUI.style.display = visible ? 'block' : 'none';
}

Putting it all Together

Now that we have our async/await syntax and loading UI implementation in place, let’s put it all together:

async function loadLevelData() {
  toggleLoadingUI(true);
  try {
    const response = await fetch('/level-data');
    const data = await response.json();
    // Do something with the data
    toggleLoadingUI(false);
  } catch (error) {
    console.error('Error loading level data:', error);
    toggleLoadingUI(false);
  }
}

In the above example, we’re calling the toggleLoadingUI function to display the loading UI before sending the request to load level data. Once the data is loaded or an error occurs, we’re calling the toggleLoadingUI function again to hide the loading UI.

Additional Tips and Tricks

Here are some additional tips and tricks to keep in mind when implementing loading UIs:

• Use a loading animations library

  Instead of using a simple loading animation, consider using a library like Loading.IO or Loaders.css. These libraries provide a wide range of customizable loading animations that can enhance the user experience.

• Display a progress bar

  Displaying a progress bar can give users an idea of how much longer they need to wait. You can use the Fetch API’s progress events to update the progress bar.

• Use a timeout

  If you’re dealing with slow internet connections or large datasets, consider implementing a timeout to hide the loading UI after a certain amount of time. This can help prevent users from getting stuck on the loading screen.

• Test thoroughly

  Testing your loading UI on different devices, browsers, and internet connections can help you identify and fix issues before they become major problems.

Conclusion

And there you have it! By using async/await syntax and implementing a simple loading UI, you can create a seamless loading experience that waits for level data to finish loading before hiding. Remember to test thoroughly and consider using loading animations libraries, progress bars, and timeouts to enhance the user experience.
