Innovation Face-Off: Solar2D vs LibGDX

For cross-platform mobile app development, amateurs to experts should turn to Solar2D. The language of games, Lua, powers this vibrant community-backed tool, offering supreme designing options and monetization. However, if you’re wedded to the Java ecosystem and desire granular control, opt for LibGDX.

Key Differences Between Solar2D and LibGDX

• Solar2D uses Lua as the primary development language while LibGDX uses Java.
• Solar2D provides a single code base applicable to variety of platforms, whereas LibGDX relies on platform-specific frameworks.
• Solar2D enables instant updates over local network through Live Builds, whereas LibGDX lacks a similar feature.
• LibGDX supports OpenGL ES 2.0/3.0 rendering, whereas Solar2D does not specify its rendering capabilities.
• Solar2D offers an easier entry point for beginners, while LibGDX offers fine-grained control beneficial for experienced developers.
• In Solar2D, users retain rights to source code, while it remains unclear in LibGDX.

Solar2D vs LibGDX: Pricing

Both Solar2D and LibGDX offer robust capabilities for game and app development without incurring any direct monetary costs.

Solar2D

Solar2D operates under an open-source, MIT license. This promotes significant cost efficiency by ensuring developers can access and manipulate the platform without encountering hidden fees or royalties. The benefit of operating in an open-source environment is the right to retain the source code. Essentially, Solar2D is 100% free to use.

LibGDX

LibGDX, an established Java game development framework, operates under the Apache 2.0 License, meaning it’s open source and free to use. Its big draw includes access to a vast array of extensive features and third-party ecosystems at no cost. The lack of a price tag coupled with the exhaustive resources make LibGDX a highly cost-effective choice for developers.

Code Examples for Solar2D & LibGDX

Solar2D

The following code snippet demonstrates a simple yet delightful splash screen built in Solar2D (formerly Corona SDK). The splash screen is a quintessential element to every mobile game, providing personality and setting the mood for the game. Make sure you have Solar2D installed version 3597 or newer, along with Lua 5.1 above.

        --Define splash screen image
local splashScreen = display.newImageRect( "splash.png", 1280, 720 )
splashScreen.x = display.contentCenterX
splashScreen.y = display.contentCenterY

--Fade out the splash screen
local function removeSplashScreen()
    transition.fadeOut( splashScreen, { time=3000 } )
end

-- call the removal function after 3 secs
timer.performWithDelay( 3000, removeSplashScreen )
    

LibGDX

This LibGDX code snippet illustrates a basic interactive button in a 2D game. Useful for designing menu interfaces which may include, start, settings, help, and quit buttons. Ensure you have LibGDX 1.9.10 or above, along with a working version of Java 8 or newer.

        import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.scenes.scene2d.Stage;
import com.badlogic.gdx.scenes.scene2d.ui.TextButton;
import com.badlogic.gdx.scenes.scene2d.ui.TextButton.TextButtonStyle;

public class MyGdxGame extends ApplicationAdapter {
    Stage stage;
    TextButton button;
    TextButtonStyle style;
    
    @Override
    public void create() {
        stage = new Stage();
        Gdx.input.setInputProcessor(stage);
        
        style = new TextButtonStyle();
        style.font = new BitmapFont();  
        
        button = new TextButton("Start Game", style);
        stage.addActor(button);
    }

    @Override
    public void render() {
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        stage.act(Gdx.graphics.getDeltaTime());
        stage.draw();
    }
    
    @Override
    public void dispose() {
        stage.dispose();
    }
}
