Texturepacker Libgdx (2024)

// Or create an AtlasSprite for advanced animation AtlasSprite cursorSprite = new AtlasSprite(gameAtlas.findRegion("cursor")); Here’s where the magic happens. You don't need to change your code logic.

If your game uses "player_stand.png" and "player_run.png" , pack them into the atlas. LibGDX’s TextureAtlas can act as a drop-in replacement for AssetManager . texturepacker libgdx

Set up your assets like this:

SpriteBatch batch = new SpriteBatch(); TexturePacker.renderDebugImage(gameAtlas, batch, 0, 0); | Problem | Solution | | :--- | :--- | | White lines around sprites | Enable edgePadding and duplicatePadding in settings. | | "Texture too large" error | Lower maxWidth to 1024 or 512. (Or check GPU limits). | | Animation frames out of order | Name files run_01.png , run_02.png . The packer sorts alphanumerically. | | AssetManager reload crash | Don't create a new TextureAtlas for every screen. Dispose the old one first. | Final Verdict: Don't Ship Without It I’ve seen prototype LibGDX games run at 25 FPS. After packing the UI and sprites into 2 atlases, they jumped to 60 FPS instantly. // Or create an AtlasSprite for advanced animation

// Instead of loading 100 textures... TextureAtlas gameAtlas = new TextureAtlas(Gdx.files.internal("ui/ui-atlas.atlas")); // Grab a single region TextureRegion buttonRegion = gameAtlas.findRegion("green_button_01"); LibGDX’s TextureAtlas can act as a drop-in replacement

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.
