今天总得东西比较多吧。到现在才把学习的结合起来用，其实，啥也没有做。不废话了
1、Actor，演员类
2、Stage，舞台类
今天2个结合起来，看看效果，今天实现的是魂斗罗的界面，由于多学的比较少，所以比嘛，比较粗糙吧。
思路吗，先从欢迎页面，点击2个人物，进入战斗界面，战斗界面通过2个按钮控制人物的左右移动，地图也随之移动。
这个用到了之前的知识，正好加强一下吧
此次用到了，Animation，TextureRegion，Texture，ImageButton，Stage，Actor
对于字体样式的就没有使用到了
废话不多说，上码
MapActor主要是用来管理地图的移动，人物的移动

关于舞台的切换
这里我使用了接口回调，主要是让MyGdxGame知道是哪个舞台发起的切换指令
舞台的切换我这里通过boolean变量在控制的
1 package com.mygdx.game; 2 3 import com.Stage.GameStage; 4 import com.Stage.IndexStage; 5 import com.badlogic.gdx.ApplicationAdapter; 6 import com.badlogic.gdx.Gdx; 7 import com.badlogic.gdx.graphics.GL20; 8 import com.badlogic.gdx.scenes.scene2d.Stage; 9 10 public class MyGdxGame extends ApplicationAdapter implements MyChangeListener { 11 /** index舞台 */ 12 IndexStage S_index; 13 /** 游戏舞台 */ 14 GameStage S_game; 15 /** 主页是否已经显示 */ 16 boolean isShowIndex = true; 17 /** 是否显示游戏页 */ 18 boolean isShowGame = false; 19 20 @Override 21 public void create() { 22 S_index = new IndexStage(this); 23 Gdx.input.setInputProcessor(S_index); 24 } 25 26 @Override 27 public void resize(int width, int height) { 28 super.resize(width, height); 29 } 30 31 @Override 32 public void pause() { 33 super.pause(); 34 } 35 36 @Override 37 public void resume() { 38 super.resume(); 39 } 40 41 @Override 42 public void dispose() { 43 super.dispose(); 44 } 45 46 float time = 0; 47 48 @Override 49 public void render() { 50 Gdx.gl.glClearColor(0, 0, 0, 1); 51 Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); 52 stage(); 53 } 54 55 private void stage() { 56 if (isShowIndex) { 57 S_index.act(); 58 S_index.draw(); 59 } else { 60 if (isShowGame) { 61 S_game.act(); 62 S_game.draw(); 63 } 64 } 65 } 66 67 @Override 68 public void changeType(Stage stage) { 69 if (stage instanceof IndexStage) { 70 isShowIndex = false; 71 isShowGame = true; 72 S_game = null; 73 S_game = new GameStage(this); 74 Gdx.input.setInputProcessor(S_game); 75 } else if (stage instanceof GameStage) { 76 isShowIndex = true; 77 isShowGame = false; 78 Gdx.input.setInputProcessor(S_index); 79 } 80 } 81 }
主要类就这2个，代码就放在了http://www.cnblogs.com/gorden178/p/4340006.html
