我LibGDX遊戲，倒塌幾分鐘後，我不知道爲什麼。我已經讀了一些關於這個問題的文章，並且說解決方案是「處理」bitmapfont，或者類似的東西。我是LibGDX的新手，我不太瞭解。完整的解釋表示讚賞。對不起，我英文很差。這是Play類。請，需要幫助。謝謝。5分鐘後的磨合，我libgdx遊戲崩潰，然後呈紅色

對於那些明顯需要幫助代碼的人，我不會得到滿意的結果。 Upvoted。 –

每次設備準備好更新屏幕時都會調用渲染。您正在每幀創建新對象。其中一些必須手動處理，這意味着調用該對象的方法.dispose()。

呼叫

font.dispose();

當你用的字體完成，以防止它吃了所有的記憶。

理想情況下，您希望在渲染循環之外創建該字體。

您應該在構造函數中創建對象，以便它們不會在每一幀中重新創建。除非這是預期的行爲。

嘗試是這樣的

public class PlayScreen implements Screen{ 

    Stage stage; 

    LabelStyle style; 
    BitmapFont font; 

    TextureAtlas backbuttonatlas; 
    TextButtonStyle backbuttonstyle;

    SpriteBatch batch; 
    Texture pibe; 
    Sprite sprite; 
    Vector2 position; 
    Game game; 

    Texture texture; 

    public PlayScreen(Game game){ 
     this.game=game; 
     font = new BitmapFont(Gdx.files.internal("font.fnt"), false); 
     style = new LabelStyle(font, Color.WHITE); 
     stage=new Stage(); 
     backskin = new Skin(); 
     backbuttonatlas = new TextureAtlas("buttons/backbutton.pack"); 
     backskin.addRegions(backbuttonatlas); 

     backbuttonstyle = new TextButtonStyle(); 
     backbuttonstyle.up = backskin.getDrawable("backbutton"); 
     backbuttonstyle.over = backskin.getDrawable("backbuttonpressed"); 
     backbuttonstyle.down = backskin.getDrawable("backbuttonpressed"); 
     backbuttonstyle.font = font; 

     backbutton = new TextButton("", backbuttonstyle); 
     backbutton.setWidth((float) (Gdx.graphics.getHeight()/8)); 
     backbutton.setHeight((float) (Gdx.graphics.getHeight()/8)); 
     backbutton.setPosition((Gdx.graphics.getWidth()/20), (float) (Gdx.graphics.getHeight()-(Gdx.graphics.getWidth()/8))); 

     backbutton.addListener(new InputListener(){

嗨。首先，需要努力。當我將所有對象的創建移動到構造函數時，它會要求我更改：'公共PlayScreen（遊戲遊戲）'。公共PlayScreen（最終遊戲遊戲）'。我該怎麼辦？。另外，如果我移動這些objets，我遇到了一個問題：'stage.addActor（backbutton）;'。它說：線程中的異常「LWJGL應用程序」... – Nicocoen97

你必須把你的「創造」像 batch = new SpriteBatch()裏面的東西

@覆蓋公共無效創建（

）{

）

你創建數十億個導致內存問題的SpriteBatches。
