来自 Drawable 的 AndEngine 纹理

我是 AndEngine 的新手。

由于某种原因，我必须从 Drawable 变量创建一个 TextureRegion。

不知道可不可以

但我的代码不起作用...

public class DrawableTextureSource implements ITextureSource {
    private final int mWidth;
    private final int mHeight;
    private final Drawable mDrawable;
    private final Context mContext;
    public DrawableTextureSource(Context context, Drawable D) {
        mContext = context;
        mDrawable = D;
        mWidth = D.getIntrinsicWidth();
        mHeight = D.getIntrinsicHeight();
    } // end DrawableTextureSource()
    public DrawableTextureSource(Context context, Drawable D, int W, int H) {
        mContext = context;
        mDrawable = D;
        mWidth = W;
        mHeight = H;
    } // end DrawableTextureSource()
    public int getWidth() {
        return mWidth;
    } // end getWidth()
        public int getHeight() {
        return mHeight;
    } // end getHeight()
        public Bitmap onLoadBitmap(Config pBitmapConfig) {
        Bitmap bitmap = Bitmap.createBitmap(1024, 1024, pBitmapConfig);
        mDrawable.draw(new Canvas(bitmap));
        return bitmap;
    } // end onLoadBitmap()
    public DrawableTextureSource clone() {
        return new DrawableTextureSource(mContext, mDrawable, mWidth, mHeight);
    } // end clone()
} // end class

我知道这不是解决这个问题的最好方法，但你可以把你的Drawable to a Bitmap然后创建一个TextureRegion来自Bitmap。 这是创建一个的代码TextureRegion from a Bitmap:

public class BitmapTextureSource implements ITextureSource {

        private Bitmap mBitmap = null;

        public BitmapTextureSource(Bitmap bitmap) {
            this.mBitmap = bitmap;
        }

        @Override
        public int getWidth() {
            return mBitmap.getWidth();
        }

        @Override
        public int getHeight() {
            return mBitmap.getHeight();
        }

        @Override
        public Bitmap onLoadBitmap() {
            return mBitmap.copy(mBitmap.getConfig(), false);
        }

        @Override
        public BitmapTextureSource clone() {
            return new BitmapTextureSource(mBitmap);
        }

    }

这是一个link https://stackoverflow.com/questions/3035692/how-to-convert-a-drawable-to-a-bitmap帮助您制作一个Bitmap从你的Drawable.

希望您能找到一种更简单的方法，但这也应该可以完成这项工作。祝你好运！
