The Camera

pet_camera/ holds one file per camera, named after the camera's item id; the mod's own is pet_camera/camera.json, and it decides how Hachiware takes photos. For how it plays, see Hachiware's Camera.

Using something else as a camera. Write another file under your own namespace, named after that item's id, and a Hachiware with that item in its backpack will take photos too.

Who takes photos. Only Hachiware takes photos. That is written in the code, and data can't change it. Whether Hachiware goes and buys a camera and film on its own is written in likes in its personality file.
