Question regarding modifiers in Data_Desktop_5E

Hi everybody,
can anybody explain what this code is good for?

Code:

---

_tModifierExclusionSets =
{
        { "DEF_COVER", "DEF_SCOVER" },
};

---

P.S.: I think, I figured it out. These 2 values/buttons are mutual exklusiv, e.g. pressing one will deselect all other in the same array.

Yes, that's correct. There are several game systems with mutually exclusive modifiers.

Regards,
JPG
