Exactly so the idea is that for some repetitive scripts that require engaging several separate entities, we could make a universal script (for whatever function it is required) and then using those empty fields input custom information.
Essentially avoid having to make a new FPI file for every new entity that has to perform the same function.
You can in fact create a new property field in FPE file of an entity by simply typing it in a new line. It won't do anything, of course, since if it's not Hard Coded as a registered FPE function like "material" "collisionmode" or "scale" BUT it will appear none the less..
Just like if you want to use a value of the variable in an FPI function, you put a % sign before the function value place,
(AMBIENCE=%variableName) the &0 sign does seem to reference to the audio input field of the entity (sound=&0).
Question is can you fetch the newly created fields?
