I am working on a game and I want to set the layout of game such that it works on Multiple device screens. So, instead of fetching images from asset's folder, I making looking for some way to fetch it from the drawable folder. So, that later on I can get the images according to the screen of the device.

Update:

I tried it using

mFaceTextureRegionLifeLine = (TiledTextureRegion) TextureRegionFactory.createFromResource(mTextureLifeLine, this, R.drawable.icon, 100, 100);

And, it fired me with and error below-

Here's the method that will do this for you:

public static TextureRegion createFromResource(final Texture pTexture, final Context pContext, final int pDrawableResourceID, final int pTexturePositionX, final int pTexturePositionY)

If you need to create a tiled texture region, use this:

public static TiledTextureRegion createTiledFromResource(final Texture pTexture, final Context pContext, final int pDrawableResourceID, final int pTexturePositionX, final int pTexturePositionY, final int pTileColumns, final int pTileRows)

Hope this helps.

  • Thanks for reply, I tried that before also and it fired me an error, please look at my update question. – Lalit Poptani Sep 05 '11 at 13:40
  • @suri sahani, Last two parameters are the number of tiles you have in columns and rows. For example if you have 6 tiles: 2 rows with 3 tiles in each, you should pass (3, 2) as parameters. – Egor Sep 05 '11 at 14:04
  • Thanks a lot! Its working fine. but do tell me what are tiles. – Lalit Poptani Sep 05 '11 at 14:13
  • @suri sahani, So what for do you need to make a tiled region? Actually, tiles are parts of an image, needed for animated sprites. Check the AnimatedSprites example in AndEngineExamples to see what effect does it give. – Egor Sep 05 '11 at 14:14
  • Well, I want to animate the images later on the Scene and that all I had done fetching images from assets folder. Thanks a lot. – Lalit Poptani Sep 05 '11 at 14:21

If you simply specify the drawble id (Such as R.drawable.icon) then depending on your device it will pull it from the folder in /res/ which is most appropriate to the device:

ie, 

/res/drawable/icon.png 
/res/drawable-large/icon.png

Would mean large devices used the second png.

See the android site for more information on supporting multiple screens.

If you want fetch images from drawable folder, you should try this ->

Context ctx = getApplicationContext();
Resources r = ctx.getResources();
Drawable d = r.getDrawable(R.drawable.image_name);
