AndEngine加載圖形：我將資產文件夾和資源放在哪里？

[英]AndEngine Loading Graphics: Where Do I put my assets folder and my resources?

問題描述

在Android Studio中使用AndEngine創建游戲時，我將資產文件夾放在項目的根目錄下。 我還在其下創建了一個名為gfx的文件夾，並將我的splash.png放在那里。

當我調用啟動畫面時： 

 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();
}

這是產生的錯誤

我在錯誤的地方放東西了嗎？ 資產應該在哪里？

2 個解決方案

解決方案1
 5  2015-01-24 13:49:26

您必須在路徑app / src / main /中創建“ assets”文件夾，並將帶有splash.png的“ gfx”文件夾放入其中

解決方案2
 0 已采納  2015-05-17 17:38:46

如果使用的是Eclipse，則應直接從eclipse創建“ gfx”文件夾，然后將splash.png圖片拖放到該文件夾​​內， 確保在出現提示時復制文件而不是鏈接文件。 鏈接會產生可訪問性問題。 這是我在eclipse中的一個小項目中的一個工作項目結構：

在此處輸入圖片說明

這是我的調用者方法的樣子： 

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();
}

出於資源優化目的，最好有一個卸載程序方法： 

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

在我的主要活動中，然后在加載資源時調用啟動屏幕的加載： 

@Override
protected void onCreateResources() {

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

}

創建新場景后，我將卸載初始畫面： 

@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這些示例，以查看飛濺是否在類似配置的任何地方，並找出問題的原因。
