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;
