關閉暫停菜單，並返回遊戲畫面 - Java遊戲與LIBGDX

Question

我需要你的幫助，一個簡單的問題。

我使用LibGDX庫實現了我的Java遊戲。我的遊戲有以下結構： - 主菜單有一些按鈕; - 遊戲畫面; - 當用戶按P關鍵字時暫停menù打開。

問題是這樣的。當我按P時，暫停菜單打開。如果我在暫停菜單中單擊MainMenù按鈕，屏幕將繼續主菜單。之後，如果我按下游戲按鈕，它會暫停菜單屏幕而不是遊戲屏幕。

我該如何解決這個問題？

我知道這是一歲，但我回答呢。

不要在渲染的每一幀中創建菜單項。創建一次。

public class GameScreen implements Screen{ 

private State state; //this keeps track of where 


public static enum State{ 
    RUNNING, PAUSE, SAVEGAME 
} 


public MenuPause(MyGdxGame game, int era){ 
    this.game=game; 
    state = State.RUNNING 

} 

@Override 
public void show() { 
    //do the loading and creating here 
} 


@Override 
public void render(float delta) { 

    Gdx.gl.glClearColor(1, 1, 1, 1); 
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); 

    switch(state){ 
     case RUNNING: running(); 
         break; 

     case PAUSE:  pause(); 
         break; 

     case SAVEGAME: savegame(); 
         break; 

     default:  break; 
    } 

} 


private void running(){ 

} 

private void pause(){ 

} 

private void savegame(){ 

} 

}
