Breaking Down the Numbers: Raylib vs Libgdx

For versatile, user-friendly game development, raylib is your optimal choice, especially for C language enthusiasts. It’s cross-platform, handles 3D with aplomb, and features unique extras like VR support. However, if Java is your language and finer control a compulsion, then libGDX with its extensive third-party ecosystem and robust feature set is the right match for you.

Key Differences Between Raylib and LibGDX

• Language: Raylib uses C, libGDX operates in Java.
• Versatility: Raylib supports over 50 programming languages, libGDX integrates well with Java-related tools.
• Target Users: Raylib is designed for prototyping, education, and embedded systems; libGDX targets game developers seeking fine-grained control.
• Support and Community: Both technologies have robust communities, but libGDX’s support is older and more extensive.
• Virtual Reality: Raylib supports VR stereo rendering while libGDX offers VR support via 3D APIs.

Code Examples for Raylib & Libgdx

Raylib

Here’s a snippet for creating a simple 2D physics simulation using Raylib. These parameters can be adjusted according to the object’s weight, simulation speed, and other physics-related properties. Ensure you have the latest version of Raylib installed to execute the code below.

#include "raylib.h"
int main() {
    int screenWidth = 800;
 int screenHeight = 450;
    InitWindow(screenWidth, screenHeight, "Raylib example");
    Vector2 ballPosition = { (float)screenWidth/2, (float)screenHeight/2 };
    Vector2 ballSpeed = { 0.0f, 0.0f };
    int ballRadius = 50;
    int gravity = 1;
    SetTargetFPS(60);
    while (!WindowShouldClose()){
        ballSpeed.y += gravity;
        ballPosition.y += ballSpeed.y;
        if (((ballPosition.y) > screenHeight - ballRadius)) ballSpeed.y *= -1;
        BeginDrawing();
        ClearBackground(RAYWHITE);
        DrawCircleV(ballPosition, ballRadius, DARKBLUE);
        EndDrawing();
    }
    CloseWindow();
    return 0;
}

Libgdx

This Libgdx code is a simple platformer game implementation. It showcases actor creation and handling user input for movements. This script must be run with a running instance of Libgdx.

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Game;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.scenes.scene2d.*;
import com.badlogic.gdx.utils.viewport.ScreenViewport;

public class MyGdxGame extends Game {
    Stage stage;
    Actor square;
    @Override
    public void create () {
        stage = new Stage(new ScreenViewport());
        square = new Actor();
        square.setX(stage.getWidth()/2);
        square.setY(stage.getHeight()/2);
        stage.addActor(square);
        Gdx.input.setInputProcessor(stage);
    }
    
    public void handleInput(){
        if(Gdx.input.isKeyPressed(Keys.RIGHT)){
            square.moveBy(1, 0);
        }
        if(Gdx.input.isKeyPressed(Keys.LEFT)){
            square.moveBy(-1, 0);
        }
        stage.act();
    }

    @Override
    public void render () {
        Gdx.gl.glClearColor(0, 0, 0, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        handleInput();
        stage.draw();
    }
    @Override
    public void dispose () {
        stage.dispose();
    }
}

The Final Stand-Off: Raylib vs LibGDX

When it comes down to Raylib and LibGDX, the decision rests in your hands, your project needs, and your preference of language and frameworks. Let’s cut to the chase.

The Passionate Prototyper

If you’re a developer who’s all about quick prototyping and craves simplicity, Raylib should be your top candidate. Developed in C, it’s a gem due to its focus on prototyping and tooling. Glacier-like graphics library inspiration flows here, with no external dependencies and support for over 50 programming languages. Plus, its powerful math module for Vector, Matrix, and Quaternion operations is a serious Game Changer.

The Java Junkie

An undeniable LibGDX attribute is the leverage it provides from the expansive Java ecosystem. The Java fanatics among us would surely choose it for being a reliable workhorse with fine-grained control and an extensive third-party ecosystem. The access to IDEs, debugging, and profiling tools, in conjunction with a well-rounded feature set from audio streaming to gesture detection, will have Java gamers cheering.

The Cross-Platform Conqueror

If your passion lies in creating products that break platform boundaries, both platforms have you covered, but LibGDX pulls ahead with iOS support, in-app purchases, and easy integration of game services. Its networking features transition smoothly across platforms, making it a preferred choice for games that require online multiplayer or cloud functionality.

Between Raylib and LibGDX, your choice boils down to personal programming preference and project specifications. If C is your tongue and prototyping your game, go Raylib. On the other hand, if Java jives with you and you require hefty cross-platform services, drive towards LibGDX.
