gradle - libgdx一段时间后无法加载纹理

Question

因此，我正在制作一款效果不错的僵尸射击游戏，但是在运行了一段时间后，却遇到了以下异常情况:

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

我知道一个事实，就是它可以正常工作，但是运行了一段时间后似乎崩溃了。

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(和/或可能的 static和/或可能的 final) Texture对象，并在游戏开始时将其加载一次，然后重复使用。

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 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...
}
