If I am building my level from a text file
0,0,0,0,0 0,1,0,1,0 0,2,1,0,0 0,0,0,0,0
and I want to draw a large image, how do I go about doing that? do I take the image, separate it in tiles (the same size as the other ones) and then add a value to each image
or is there another way to do this? Lets say I want to add a house, or a something like this ship?
