Code Examples for LibGDX & LWJGL

LibGDX

Let’s showcase a small example of sprite flipping in LibGDX. This is a key technique in creating animations in a game. We assume you have a working knowledge of sprite creation.

                import com.badlogic.gdx.Game;
        import com.badlogic.gdx.graphics.g2d.Sprite;
        import com.badlogic.gdx.graphics.g2d.SpriteBatch;

        public class FlipDemo extends Game{
            private Sprite sprite;
            private SpriteBatch batch;
            
            @Override
            public void create(){
                batch = new SpriteBatch();
                sprite = new Sprite(new Texture(Gdx.files.internal("image.png")));
            }
            
            @Override
            public void render(){
                batch.begin();
                sprite.draw(batch);
                if (Gdx.input.isTouched()){
                    sprite.flip(true, false);
                }
                batch.end();
            }
        }
    

LWJGL

Let’s dive into LWJGL with a code example that features the creation of a simple window. To run this code, LWJGL and GLFW dependencies must be appropriately set up.

                import org.lwjgl.*;
        import org.lwjgl.glfw.*;
        import static org.lwjgl.opengl.GL11.*;
        import static org.lwjgl.system.MemoryUtil.NULL;

        public class GLFWWindowDemo {
            public void run() {
                long window;
                
                // Initialize the library
                if (!glfwInit())
                    throw new IllegalStateException("Unable to initialize GLFW");

                // Create our window
                window = glfwCreateWindow(800, 600, "Hello LWJGL", NULL, NULL);
                
                // Make the OpenGL context current
                glfwMakeContextCurrent(window);
                
                // Loop until the user closes the window
                while (glfwWindowShouldClose(window) == GLFW_FALSE) {
                    glfwSwapBuffers(window); // swap the color buffers
                    glfwPollEvents();
                }
            }

            public static void main(String[] args) {
                new GLFWWindowDemo().run();
            }
        }
     

“` The code language to be used in the lang class and data-lang attribute should be “lang-java” as both LibGDX and LWJGL use Java.

The Face-off: LibGDX vs LWJGL – Which to choose?

The battle between LibGDX and LWJGL for supremacy is an intense one, with both Java libraries offering unique traits. Dig in to find which fits the bill for your requirements.
