libgdx 一段时间后加载纹理失败

Question

所以我正在制作一款运行良好的僵尸射击游戏，但在运行一段时间后我遇到了这个异常：

Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: 
    Couldn't load file: 1zom3.png

我知道图像在工作时确实存在，但似乎在运行之后它崩溃了。

这是它崩溃的方法：

public void changeState(int i)
{
    //changes the state and concurrently the image associated with the given state
    state = i;
    sprite = new Sprite(new Texture(Gdx.files.internal(name+i+suff)));//crashes here
    bounding = (sprite.getBoundingRectangle());
    if (sprite.getTexture().getTextureData().isPrepared()==false)
    {
        sprite.getTexture().getTextureData().prepare();
    }
    playerMap = sprite.getTexture().getTextureData().consumePixmap();
}

正如@Tenfour04 指出的那样，这可能是内存不足的问题。

而不是这样做：

sprite = new Sprite(new Texture(Gdx.files.internal(name+i+suff)));

创建一个全局对象（and/or 可能 static and/or 可能 final）Texture 对象，并在游戏开始时仅加载一次并重复使用它。

像这样：

public static Texture myTexture_1;           //<< your texture
public static final int ID_MY_TEXTURE_1 = 1; //<< this will work as an ID

// This method is called once in your game (like in the create() method)...
public static void load() {
    myTexture_1 = new Texture(Gdx.files.internal(name + ID_MY_TEXTURE_1 + suff));
}

// when no longer necessary, remove it...
public static void dispose() {
    myTexture_1.dispose();
    // and so on...
}

然后，在您的 changeState() 方法中，进行切换以检索正确的纹理：

public void changeState(int i) {
    state = i;
    switch(i){
        case ID_MY_TEXTURE_1 :
        sprite = new Sprite(myTexture_1);
        break;
        // rest of cases...
    }
    // rest of your code...
}
