Hello World

Edit

"Hello World" is a common example of getting started with programming, here we will show you how to add Hello World with HaxeFlixel's FlxText. You can compile this test for any supported target platform.

Make sure you have installed Flixel, as well as set up the lime and flixel commands as explained previously.

Create a new HaxeFlixel Project

HaxeFlixel requires a basic structure of files for any project that you can automatically create with the template command (tpl for short).

flixel tpl -n "HelloWorld"

You will now see a new folder named "HelloWorld" with all the files for your project being created automatically.

Add the "Hello World" FlxText

Adding the text is as simple as opening the PlayState.hx file in the newly created source folder. The file should look like this:

package;

import flixel.FlxState;

class PlayState extends FlxState
{
    override public function create():Void
    {
        super.create();
    }

    override public function update(elapsed:Float):Void
    {
        super.update(elapsed);
    }
}

All you need to do is add the following three lines to the create() function (and save the file):

var text = new flixel.text.FlxText(0, 0, 0, "Hello World", 64);
text.screenCenter();
add(text);

This will create a new FlxText instance with font size 64, center it on the screen and add() it so it is displayed.

Test the Project

Return to your command line window. Now we can compile the project.

Without running the lime setup commands you can compile to Flash, Neko and HTML5 out of the box.

Test your project with the following commands:

lime test flash
lime test neko
lime test html5

Note: While compiling, you may see some warnings such as "Use programPath instead" (or "Could not find generated font file" for HTML5). These can safely be ignored.
