Using LibGDX, how do you have an animation using seperate images ?

Question

I\'m learning how to make games using LibGDX and I\'m trying to make a small platform game (using Eclipse). I made 4 images on the main character running to make an animatio

You should use a TexturePacker with TextureAtlas. Adding every texture by hand is not the right way.

The texture packer packs your several images into one image. Use names like this: img_01.png, img_02.png etc, and you extract them all in one line of code in an Array.

I will post code examples in a few hours when i get home.

I actually had an separate class for dealing with loading of assets:

public abstract class Assets {
private static AssetManager asm = new AssetManager();
private static String assetsPackPath = "assets.pack";
public static TextureAtlas atlas;

public static void load(){
    asm.load(assetsPackPath, TextureAtlas.class);
    asm.finishLoading();

    atlas = asm.get(assetsPackPath);
}

public static void dispose(){
    asm.dispose();
}
}

And the code that loads animation :

playerRun = new Animation(1/10f, Assets.atlas.findRegions("run"));
playerRun.setPlayMode(Animation.PlayMode.LOOP);

My original animation images were run_001.png, run_002.png, ...

Because your file names have a format name_0001.png the Texture packer puts animation keyframes in one file and they all have one name "name" and a additional parameter "index" that is the number in your file name, for example 001, 002, 003, etc.

And Assets.atlas.findRegions("run") returns an Array with the keyframes.
