Time for action – modifying our application

Before we dive into more complex examples, let's alter some minor things in our program by performing the following steps:

1. Let's alter the second line of main.lua to display as follows:

   textObject = display.newText( "Hello World!", 160, 80, native.systemFont, 36 )
   textObject:setFillColor( 0.9, 0.98 ,0 )

2. Save your file and go back to the Corona simulator. The simulator will detect a change from your file and automatically relaunch with the changes. If the simulator doesn't relaunch automatically upon saving your file, press Command + R (Mac) / Ctrl + R (Windows). You will see the following output on the screen:
   

Note

As you continue learning more Corona functions, you'll notice that some of the text values will be optional. In this case, we need to use five values.
