libgdx动画采用Animation实现，即通过帧动画实现。
代码如下：
1 package com.fxb.newtest; 2 3 import com.badlogic.gdx.ApplicationAdapter; 4 import com.badlogic.gdx.Gdx; 5 import com.badlogic.gdx.graphics.GL10; 6 import com.badlogic.gdx.graphics.Texture; 7 import com.badlogic.gdx.graphics.g2d.Animation; 8 import com.badlogic.gdx.graphics.g2d.SpriteBatch; 9 import com.badlogic.gdx.graphics.g2d.TextureRegion; 10 11 public class Lib002_Animation extends ApplicationAdapter{ 12 13 Texture texture; 14 Animation animation; 15 SpriteBatch batch; 16 float currentTime = 0; 17 18 @Override 19 public void create() { 20 // TODO Auto-generated method stub 21 batch = new SpriteBatch(); 22 texture = new Texture( Gdx.files.internal( "data/koalio.png" ) ); 23 TextureRegion region = new TextureRegion( texture ); 24 TextureRegion[] regions = region.split( 18, 26 )[0]; 25 26 animation = new Animation( 0.1f, regions[1], regions[2], regions[3], regions[4] ); 27 } 28 29 @Override 30 public void render() { 31 // TODO Auto-generated method stub 32 Gdx.gl.glClearColor( 1, 1, 1, 1 ); 33 Gdx.gl.glClear( GL10.GL_COLOR_BUFFER_BIT ); 34 35 currentTime += Gdx.graphics.getDeltaTime(); 36 TextureRegion region = animation.getKeyFrame( currentTime, true ); 37 38 batch.begin(); 39 batch.draw( region, 100, 100, region.getRegionWidth(), region.getRegionHeight() ); 40 batch.end(); 41 } 42 43 @Override 44 public void dispose() { 45 // TODO Auto-generated method stub 46 super.dispose(); 47 } 48 49 }
运行效果：
