AndEngine Loading Graphics:我在哪里放置我的资源文件夹和我的资源?

在使用Android Studio的AndEngine创建游戏时,我将我的资源文件夹放在项目的根级别。我还在它下面创建了一个名为gfx的文件夹,并将我的splash.png放在那里。

当我拨打启动画面时:

 public void loadSplashScreen()
{
    BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
    splashTextureAtlas = new BitmapTextureAtlas(activity.getTextureManager(), 390, 534, TextureOptions.BILINEAR);
    splash_region = BitmapTextureAtlasTextureRegionFactory.createFromAsset(splashTextureAtlas, activity, "splash.png", 0, 0);
    splashTextureAtlas.load();
}

这是产生的错误

我把东西放在错误的地方吗?资产应该在哪里?

2 个答案:

答案 0 :(得分:5)

你必须在路径app / src / main /中创建“assets”文件夹,并将带有splash.png的“gfx”文件夹放入其中

答案 1 :(得分:0)

如果你正在使用Eclipse,你应该直接从eclipse创建“gfx”文件夹,然后将splash.png图片拖放到文件夹中,确保你复制文件,而不是链接它,当提示。链接可能会产生可访问性问题。 这是我在eclipse中的一个小项目中的一个工作项目结构:

enter image description here

以下是我的调用方法:

public void loadSplashResources() {
    BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/splash/");
    mSplashTextureAtlas = new BitmapTextureAtlas(mActivity.getTextureManager(), 480, 800, TextureOptions.BILINEAR);
    mSplashTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(mSplashTextureAtlas, mActivity, "splash.png", 0, 0);
    mSplashTextureAtlas.load();
    mFont1 = FontFactory.create(mActivity.getFontManager(), mActivity.getTextureManager(), 256, 256, Typeface.create(Typeface.DEFAULT, Typeface.NORMAL), 10, Color.GRAY);
    mFont1.load();
}

为资源优化目的使用卸载器方法也是明智的:

public void unloadSplashResources() {
    mSplashTextureAtlas.unload();
    mSplashTextureRegion = null;
    mFont1.unload();
    mFont1 = null;
}

在我的主要活动中,我在加载资源时调用加载闪屏:

@Override
protected void onCreateResources() {

    mResourceManager = ResourceManager.getInstance();
    mResourceManager.prepare(this);
    mResourceManager.loadSplashResources();
    mSceneManager = SceneManager.getInstance();

}

一旦我创建了一个新场景,我就会卸载它:

@Override
protected Scene onCreateScene() {
    mEngine.registerUpdateHandler(new TimerHandler(2f, new ITimerCallback() {
        public void onTimePassed(final TimerHandler pTimerHandler) {
            mEngine.unregisterUpdateHandler(pTimerHandler);
            mResourceManager.loadGameResources();
            mSceneManager.setScene(SceneType.SCENE_MENU);
            mResourceManager.unloadSplashResources();
        }
    }));

希望您可以交叉引用这些示例以查看您的启动是否在任何类似配置的位置,并找到问题的原因。
