libgdx学习记录3——动画Animation

libgdx动画采用Animation实现，即通过帧动画实现。

代码如下：

 package com.fxb.newtest;

 import com.badlogic.gdx.ApplicationAdapter;
 import com.badlogic.gdx.Gdx;
 import com.badlogic.gdx.graphics.GL10;
 import com.badlogic.gdx.graphics.Texture;
 import com.badlogic.gdx.graphics.g2d.Animation;
 import com.badlogic.gdx.graphics.g2d.SpriteBatch;
 import com.badlogic.gdx.graphics.g2d.TextureRegion;

 public class Lib002_Animation extends ApplicationAdapter{

     Texture texture;
     Animation animation;
     SpriteBatch batch;
     float currentTime = 0;

     @Override
     public void create() {
         // TODO Auto-generated method stub
         batch = new SpriteBatch();
         texture = new Texture( Gdx.files.internal( "data/koalio.png" ) );
         TextureRegion region = new TextureRegion( texture );
         TextureRegion[] regions = region.split( 18, 26 )[0];

         animation = new Animation( 0.1f, regions[1], regions[2], regions[3], regions[4] );
     }

     @Override
     public void render() {
         // TODO Auto-generated method stub
         Gdx.gl.glClearColor( 1, 1, 1, 1 );
         Gdx.gl.glClear( GL10.GL_COLOR_BUFFER_BIT );

         currentTime += Gdx.graphics.getDeltaTime();
         TextureRegion region = animation.getKeyFrame( currentTime, true );

         batch.begin();
         batch.draw( region, 100, 100, region.getRegionWidth(), region.getRegionHeight() );
         batch.end();
     }

     @Override
     public void dispose() {
         // TODO Auto-generated method stub
         super.dispose();
     }

 }

运行效果：
