How to Create a Global Chatting App in code.org

In this tutorial, I will guide You on how to Create a global chatting app using code.org. Code.org is a platform that allows you to develop apps and games using Java. With the app we will build today, users will be able to chat with each other from all around the world. Let's get started!

Introduction

Creating a global chatting app is a great way to connect with people from different parts of the world. In this tutorial, we will use code.org to build our app and add various features to make the chatting experience enjoyable.

Creating an App in code.org

To begin, open Google Chrome and search for "Studio.code.org" in the search bar. Press enter and sign in to your code.org account. Once you're signed in, click on the "Create" button and select "App Lab" from the drop-down menu. Wait for the interface to load.

Designing the Chat Interface

Once the interface has loaded, you can start designing your app. First, rename your app to "We Chat" to give it a personalized touch. Next, let's focus on the design portion. I suggest using a polar theme as it gives a good look for a chatting app. You can also add an image and an icon to make it visually appealing.

Now, let's select the font family. I recommend using the "Arial Black" font as it looks nice and is suitable for a chatting app. You can also adjust the positioning of the elements to make them visually pleasing. For a 3D look, you can duplicate elements and keep the icons white.

Adding Functionality to the App

Now that the design is complete, let's move on to adding functionality to the app. We will start by setting up event handlers. These handlers will be triggered when certain actions are performed, such as clicking a button or typing in a text input.

Next, we will create records in the data table to store the messages sent by users. By creating a record for each message, we can display them in the chat interface. The sender's name will be taken from the username entered by the user, while the message content will be taken from the text input.

Finally, we will display the sent and received messages in the chat interface. By using the "on Record event" function, we can retrieve the messages from the data table and display them in the text area.

Testing the App

Before we conclude, it's important to test the app to ensure everything is working as expected. Make sure to delete any previous records and start testing with a fresh interface. Send messages to see if they are displayed correctly and test the chat functionality to ensure a smooth user experience.

Conclusion

Creating a global chatting app in code.org is a fun and rewarding project. By following the steps outlined in this tutorial, you can confidently build your own app and connect with people from all over the world. Enjoy coding and happy chatting!
