Texturepacker Libgdx May 2026

// Before Texture playerTex = new Texture("player.png"); // After (no logic change needed in your entity class) TextureRegion playerTex = gameAtlas.findRegion("player"); 1. 9-Patch (Scalable UI) Name your raw files with .9 (e.g., panel.9.png ). In TexturePacker GUI, enable StripWhitespace and Ignore blanks . LibGDX will automatically load them as NinePatch objects. 2. Pixel Perfect (Retro Games) If you make pixel art, turn off filtering (set to Nearest ) and turn on edgePadding = false to prevent bleeding between sprites. 3. Debug Visualization LibGDX has a built-in debugger for atlases. Render this to see if your packing is efficient (red = empty space):

public class AtlasPacker public static void main(String[] args) // Settings TexturePacker.Settings settings = new TexturePacker.Settings(); settings.maxWidth = 2048; settings.maxHeight = 2048; settings.pot = true; // Power of two (required for legacy devices) settings.filterMin = TextureFilter.Nearest; settings.filterMag = TextureFilter.Nearest; // Input: raw images, Output: folder for assets TexturePacker.process(settings, "../raw-assets/ui", "../android/assets/ui", "ui-atlas"); System.out.println("Packing complete!"); texturepacker libgdx

If you’ve been developing with LibGDX for more than a week, you’ve likely heard the mantra: “Batch your draw calls!” // Before Texture playerTex = new Texture("player

Set up your assets like this:

assets-raw/ ui/ buttons/ backgrounds/ characters/ player/ enemy/ Every folder you point TexturePacker at becomes one "Atlas" (one .atlas file + one .png ). Step 3: Running the Packer (The LibGDX Way) Inside your LibGDX project (usually in your core module or a standalone desktop launcher), write a small one-off packing script. LibGDX will automatically load them as NinePatch objects
