Hi Denki,
Thank you for responding to all of my questions. You have greatly help me to enjoy Autonauts and to understand how it works. I have another question for you about the Save.txt file. I see that after the large section of "Tiles" in it, the next section starts with "TileExtra":[{"x":324,"y":26,"T":0},{"x":325,"y":26,"T":0}, and there are very many of what I call these "Pair-Triplets". The "Pair-Triplets" all contain {"x": followed by a value and then ,"y": followed by a value and then ,"T": followed by a value followed by }, . I presume that the "x" value refers to the column location and "y" value refers to the row location and "T" value might refer to a type value.
Would you please clarify the actual meanings and uses of the "TileExtra" information? If the "T" values refer to types, what are those types and how are the used? Thank you.
