The idea is to separate the exported data (bin, json, xml) from the project
configuration, so someone could create a new project on his main folder and
point where the images (probably before a texture pack) are, and map the images
with a key to be identified when loading the fixtures, for example:
project file:
export location
default export type
map of key,imagelocation
door -> images/mysuperdoor.png
house -> images/somehouse.png
exported fixtures file:
door -> a polygon
house -> another polygon
Working in this way, you can avoid having the images location as the exported
fixtures identifier instead you use the key you want for them. Also, the
exported fixture file could be anywhere.
Don't know if I explained the issue well, hope I did and hope you find this
useful.
