![]() (Or, manually copy the files after publishing them.) The basename of the files should be fine at this point, but feel free to change them as you see fit. Change the "Data file" and "Texture file" entries in Texture Settings to save directly to your libGDX project's Android "asset" folder.The libGDX TextureAtlas expects these two files to be in the same directory (and the name of the image file is embedded in the.txt file that describes the atlas (in a format that libGDX expects), and an image file (. TexturePacker will generate two files for a libGDX atlas: a. Under Output change the "Data Format" to "LibGDX". ![]() In the Texture Settings along the left side, make sure the Output section is open.I use "packed.tps" as the save-file name in this example. Click 'Save As.' in the File menu to save your state and give the output files some default names.Add a couple sprites to this Atlas, you can add more later. Click 'Add Sprites' on the toolbar or in the Edit menu.Note that you can have multiple atlases open for editing (each time you click 'New' a new TexturePacker window is opened.) By default a new, empty project is started. Texture files, and you just want to switch to a texture atlas. Ideally, you should have an application that already works with individual I assume you've got your libGDX application set up already (especially This tutorial is based on the Pro version of TexturePacker 2.4.2. This tutorial walks through the most basic aspects of using it with I’ll be developing my Infinite Runner further, so visit again soon for more.Tags: libgdx, texture atlas, texturepacker Tutorial for TexturePacker and libGDXīuilding an optimized texture atlas for texture-heavy applications. TexturePacker GUI (also free and my tool of choice)Īfter this was done, I hooked it all up and ended up with a player sprite running, jumping and falling around the screen like this!.Slice up your sprite sheet manually and repack it using a repacking tool, for example:.Follow the examples and note that the coordinate system is where (x, y) = (0, 0) is the top left corner and positive in the right and down directions. There are two ways to go about this generally: atlas file provided with most sprite sheets (understandably, since who knows what kind of game engine programmers want to use). It’s defined in an *.atlas file and sits alongside the image in the libGDX assets folder. Creating a Texture Atlas for LibGDXĪ texture atlas can basically define regions on your sprite sheet. In order to split up the one sprite sheet into four separate animations easily, I created a Texture Atlas for the sprite sheet. To simplify drawing, I created a PlayerDrawer class, which chooses which animation and which frame to draw based on the time and player state. getKeyFrame() method which will return the frame in the sprite sheet that is to be drawn at that point in time. An Animation object can be instantiated with an Array of the textures that make up an animation. Perfect for my infinite runner game! Player Animation with LibGDX This sprite sheet contains frames for standing, running, jumping and falling. An example is shown below, taken from OpenGameArt – link here This sequence of images can be collated into one image, called a sprite sheet. The Basics of Animation with Sprite SheetsĢD Animation, like in Television and Film, works by displaying images (each called a frame) in quick succession. To do this, we need to know a little about Animation. No more default libGDX happy smiley face Texture □ I know I haven’t posted in a while, but the Infinite Runner project continues! Today I’ll be adding a character sprite sheet to the game.
