我知道我的标题很困惑,但不知道如何以最容易理解的方式提出这个问题。希望你明白。
在我的游戏中有2个类
- “mainActivity”游戏 View 。
- “Game”扩展了 SurfaceView 并实现了 Runnable(游戏循环)。
第一个屏幕显示“开始新游戏”按钮,一旦您单击该按钮,setContentView 将替换其显示 View game.class。
目前一切正常。现在,假设玩家输了,我想返回主屏幕,只要他点击“开始新游戏”,游戏就会从头开始。
当前点击返回键“从0重新开始游戏”
这是我的类(class):
主要 Activity :
public class MainActivity extends Activity implements OnTouchListener {
DialogPause pauseDialog;
public MyPreferences pref;
private TextView txCoins;
public Game game;
public static Music music;
ViewAnimator viewAnimator;
@SuppressLint("ClickableViewAccessibility")
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
pref = new MyPreferences(this);
music = new Music(this);
pauseDialog = new DialogPause(this);
setContentView(R.layout.menu);
view();
}
public void view(){
txCoins = (TextView)findViewById(R.id.txCoins);
txCoins.setText("Coins "+pref.getInt("coins"));
}
public void newGame(){
if(game != null){
game.destroyed();
}
game = new Game(this);
game.start();
game.setOnTouchListener(this);
setContentView(game);
}
public void click(View v){
newGame();
}
protected void onStart() {
super.onStart();
}
@Override
protected void onStop() {
music.StopBackgroundMusic();
super.onStop();
}
@Override
public void onBackPressed() {
newGame();
}
游戏循环类:
public class Game extends SurfaceView implements Runnable{
public static MyPreferences pref;
public static Levels level;
public static int SCREEN_W;
public static int SCREEN_H;
public static boolean running;
public static boolean pause = false;
private Thread thread = null;
private SurfaceHolder holder;
private Canvas canvas;
private Paint p = new Paint();
public static Handler handler = new Handler();
public static Resources res;
public Timer timer;
public Game(Context context) {
super(context);
res = getResources();
holder = getHolder();
level = new Levels();
timer = new Timer();
pref = new MyPreferences(context);
System.out.println("Create Game instance");
}
public void run() {
init();
long lastTime = System.nanoTime();
double delta = 0;
double ns = 1000000000.0 / 30.0;
System.out.println("Run method" + running);
//Start looping...
while (running) {
//If it's not pause
long now = System.nanoTime();
delta+=(now - lastTime) / ns;
lastTime = now;
if(!holder.getSurface().isValid()){continue;}
canvas = holder.lockCanvas();
SCREEN_W = canvas.getWidth();
SCREEN_H= canvas.getHeight();
while (delta >-1) {
if(!pause)tick();
delta--;
}
level.level1();
render(canvas);
holder.unlockCanvasAndPost(canvas);
if(ControlPanel.PLAYER_POWER <=0){
System.out.println("Loose!");
ControlPanel.PLAYER_POWER = 100;
stop();
start();
}
}
}
private void render(Canvas c) {
handler.render(c);
textOnScreen(c);
}
public void tick(){
handler.tick();
}
public void init(){
ControlPanel.COINS = pref.getInt("coins");
MainActivity.music.backgroundMusic();
handler.addSpaceShip(new Player(500, 500, 10, 10, handler, Sprite.getSprite(0)));
// handler.addKing(new King(Game.SCREEN_W / 2, 100,
// 40, 40, handler, Sprite.getSprite(18), 0));
}
public void start() {
//If the tread are new one
if(thread==null){
thread = new Thread(this);
thread.start();
timer.start();
}
//if it not running
if(!running) {
pause = false;
running =true;
}
}
public void stop() {
pause = true;
running = false;
timer.stop();
pref.putInt("coins", ControlPanel.COINS);
}
public void pause() {
pause = true;
}
public void destroyed() {
System.out.println("Stop");
running = false;
this.stop();
}
public void textOnScreen(Canvas c){
p = new Paint();
p.setColor(Color.YELLOW);
p.setTextSize(50);
c.drawText("POWER = " + ControlPanel.PLAYER_POWER, SCREEN_W / 2 ,50 , p);
c.drawText("Time = " + timer.timeFormat(), 100 ,50 , p);
c.drawText("Coins = " + ControlPanel.COINS, 10 ,SCREEN_H - 10 , p);
p.setColor(Color.WHITE);
c.drawText("Bullets = " +ControlPanel.BULLET, SCREEN_W - 390,SCREEN_H - 10 , p);
p.setColor(Color.WHITE);
c.drawText(ControlPanel.Distance + " km ", SCREEN_W /2 - 200,SCREEN_H - 10 , p);
}
}
请帮忙!!我已经一个半星期了,无法解决:((
最佳答案
我想当它到达 System.out.println("Loose!");
时您想返回到第一个菜单,因为您说它现在已经运行良好。我没有时间阅读所有代码,但如果它是你想要的,那么你可以尝试这个解决方案。我在每个类中添加了处理程序变量以重新启动程序。
public class MainActivity extends Activity implements OnTouchListener {
DialogPause pauseDialog;
public MyPreferences pref;
private TextView txCoins;
public Game game;
public static Music music;
ViewAnimator viewAnimator;
Handler uiHandler = new Handler(){
@override
public void handleMessage (Message msg){
restart();
}
}
@SuppressLint("ClickableViewAccessibility")
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
pref = new MyPreferences(this);
music = new Music(this);
pauseDialog = new DialogPause(this);
setContentView(R.layout.menu);
view();
}
private void restart(){
setContentView(R.layout.menu);
view();
}
public void view(){
txCoins = (TextView)findViewById(R.id.txCoins);
txCoins.setText("Coins "+pref.getInt("coins"));
}
public void newGame(){
if(game != null){
game.destroyed();
}
game = new Game(this, handler);
game.start();
game.setOnTouchListener(this);
setContentView(game);
}
public void click(View v){
newGame();
}
protected void onStart() {
super.onStart();
}
@Override
protected void onStop() {
music.StopBackgroundMusic();
super.onStop();
}
@Override
public void onBackPressed() {
//newGame(); //comment out this
}
和游戏类:
public class Game extends SurfaceView implements Runnable{
private Handler handler;
public static MyPreferences pref;
public static Levels level;
public static int SCREEN_W;
public static int SCREEN_H;
public static boolean running;
public static boolean pause = false;
private Thread thread = null;
private SurfaceHolder holder;
private Canvas canvas;
private Paint p = new Paint();
public static Handler handler = new Handler();
public static Resources res;
public Timer timer;
public Game(Context context, Handler handler) {
super(context);
this.handler = handler;
res = getResources();
holder = getHolder();
level = new Levels();
timer = new Timer();
pref = new MyPreferences(context);
System.out.println("Create Game instance");
}
public void run() {
init();
long lastTime = System.nanoTime();
double delta = 0;
double ns = 1000000000.0 / 30.0;
System.out.println("Run method" + running);
//Start looping...
while (running) {
//If it's not pause
long now = System.nanoTime();
delta+=(now - lastTime) / ns;
lastTime = now;
if(!holder.getSurface().isValid()){continue;}
canvas = holder.lockCanvas();
SCREEN_W = canvas.getWidth();
SCREEN_H= canvas.getHeight();
while (delta >-1) {
if(!pause)tick();
delta--;
}
level.level1();
render(canvas);
holder.unlockCanvasAndPost(canvas);
if(ControlPanel.PLAYER_POWER <=0){
System.out.println("Loose!");
ControlPanel.PLAYER_POWER = 100;
stop();
handler.sendEmptyMessage(0);//restart the game menu as u want
//start();//Comment out this
}
}
}
private void render(Canvas c) {
handler.render(c);
textOnScreen(c);
}
public void tick(){
handler.tick();
}
public void init(){
ControlPanel.COINS = pref.getInt("coins");
MainActivity.music.backgroundMusic();
handler.addSpaceShip(new Player(500, 500, 10, 10, handler, Sprite.getSprite(0)));
// handler.addKing(new King(Game.SCREEN_W / 2, 100,
// 40, 40, handler, Sprite.getSprite(18), 0));
}
public void start() {
//If the tread are new one
if(thread==null){
thread = new Thread(this);
thread.start();
timer.start();
}
//if it not running
if(!running) {
pause = false;
running =true;
}
}
public void stop() {
pause = true;
running = false;
timer.stop();
pref.putInt("coins", ControlPanel.COINS);
}
public void pause() {
pause = true;
}
public void destroyed() {
System.out.println("Stop");
running = false;
this.stop();
}
public void textOnScreen(Canvas c){
p = new Paint();
p.setColor(Color.YELLOW);
p.setTextSize(50);
c.drawText("POWER = " + ControlPanel.PLAYER_POWER, SCREEN_W / 2 ,50 , p);
c.drawText("Time = " + timer.timeFormat(), 100 ,50 , p);
c.drawText("Coins = " + ControlPanel.COINS, 10 ,SCREEN_H - 10 , p);
p.setColor(Color.WHITE);
c.drawText("Bullets = " +ControlPanel.BULLET, SCREEN_W - 390,SCREEN_H - 10 , p);
p.setColor(Color.WHITE);
c.drawText(ControlPanel.Distance + " km ", SCREEN_W /2 - 200,SCREEN_H - 10 , p);
}
}
