Matrix Object reference not set to an instance of an object

Hi Will,

Thanks about the tip about the call-stack that one helped with some other things that I had read.
Turned out I didn’t properly initialize every instance of grass.

            grass = new Animation[Width, Height];
            Vector2 position = Vector2.Zero;
            for (int i = 0; i < Width; i++)
                for (int j = 0; j< Height; j++)
                    //grass[i,j] = new Animation();
                    position.X = i * TileWidth;
                    position.Y = j * TileHeight; 

Adding the commented line (uncommented) solved everything. I will keep in mind to make my own little bugs once in a while :wink:
