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.
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. texturepacker libgdx
Now, load them in your game:
If you’ve been developing with LibGDX for more than a week, you’ve likely heard the mantra: “Batch your draw calls!” SpriteBatch batch = new SpriteBatch(); TexturePacker
