How to get Resources from drawable folder - AndEngine

Question

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-

So, if it is possible let me know. Thanks, Suri Sahani.

Answer 1

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.

Answer 2

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.
