Question

I want to be able to rotate a moving sprite which is also animated (atm has 3 images in a row). How would I go about this?

The current sprite moves around the screen and rotates.

So far I’ve got this code: (But it looks messed up)

    this._rect = new Rect(0,0, this._spriteWidth, this._spriteHeight);

    //this._rect.left = 1 * this._spriteWidth;
    //this._rect.right = this._rect.left + this._spriteWidth;

    //What the bitmap will be fitted into.
    Rect dest = new Rect(current_Position.x, current_Position.y, current_Position.x + this._spriteWidth, current_Position.y + this._spriteHeight);

    mMatrix.reset();
    mMatrix.postRotate(Degrees, _spriteWidth / 3, _spriteHeight / 2);
    mMatrix.postTranslate(current_Position.x, current_Position.y);

    this._modified_bitmap = Bitmap.createBitmap(_bitmap, 0, 0, _bitmap.getWidth(), _bitmap.getHeight(), mMatrix, false);

    canvas.drawBitmap(_modified_bitmap, _rect, dest, null);

Can anyone help thanks?

    mMatrix.reset();
    mMatrix.postRotate(Degrees, _spriteWidth / 3, _spriteHeight / 2);
    mMatrix.postTranslate(current_Position.x, current_Position.y);

    this._modified_bitmap = Bitmap.createBitmap(_bitmap, 0, 0, _spriteWidth, _spriteHeight);

    canvas.drawBitmap(_modified_bitmap, mMatrix, null);
