Hi, I recently downloaded the version of Solarus with the Quest Editor because I wanted to create my own Zelda-like game someday. When I figured out that I needed a DAT file and learned how to make one for my sprite sheets, I am confused about something. When reading the DAT file for a chest, I noticed how a 16-pixel by 16-pixel chest has an origin_x of 8 (which is understandable since it's half the length of the chest), but I am so confused as to why the origin_y is 13. Could someone knowledgeable explain this to me?
