Corona SDK: Create an Alphabet Soup Game - Interaction

Welcome to the final tutorial in our Alphabet Soup game series! In this tutorial, we'll handle word selection and the steps necessary to build the final app.


Step 1: Hit Test Objects Function

We'll use an excellent and useful function for collision detection without physics. You can find the original example and source at the Ansca Code Exchange website.


Step 2: Detect Letters

The next function will run when the user lifts the finger used to select the word. It will calculate the selected letters using the function created in the previous step.


Step 3: Get Selected Letters

A string variable is created to store the letters highlighted by the line.


Step 4: Check If Word is On List

This code checks the generated string and compares it to the elements in the words table. If the word is found a sound is played and the counter rises.


Step 5: Check for Game Over

When the counter reaches the same amount of words in the table an alert is called.


Step 6: Alert

The alert function stops the game, removes the listeners, and displays a game status message.


Step 7: Call Main Function

In order to initially start the game, the Main function needs to be called. With the above code in place, we'll do that here:


Step 8: Loading Screen

The Default.png file is an image that will be displayed right when you start the application while iOS loads the basic data to show the Main Screen. Add this image to your project source folder, it will be automatically added by the Corona compiler.


Step 9: Icon

Using the graphics you created before you can now create a nice and good looking icon. The icon size for the non-retina iPhone icon is 57x57px, but the retina version is 114x114px and the iTunes store requires a 512x512px version. I suggest creating the 512x512 version first and then scaling down for the other sizes.

It doesn't need to have the rounded corners or the transparent glare, iTunes and the iPhone will do that for you.


Step 10: Testing in Simulator

It's time to do the final test. Open the Corona Simulator, browse to your project folder, and then click open. If everything works as expected, you are ready for the final step!


Step 11: Build

In the Corona Simulator go to File > Build and select your target device. Fill the required data and click build. Wait a few seconds and your app will be ready for device testing and/or submission for distribution!


Conclusion

Experiment with the final result and try to make your custom version of the game!
