But when trying to add a new element on this property, it simply does nothing (array is still empty). Using the same script with no modifications, but filling the array with a "dummy" element via CK suddenly works just fine. | But when trying to add a new element on this property, it simply does nothing (array is still empty).

After some further testing I found the issue: If you have a property array, you have to make sure that it is either assigned a value via CK, or initialise it somewhere in the code (preferably in OnInit()). If you do not initialise the array via CK with at least one element, the array will be none and thus no functions such as Add() will work. | After some further testing I found the issue: If you have a property array, you have to make sure that it is either assigned a value via CK, or initialise it somewhere in the code (preferably in OnInit()).

All you need to do is create a new array with a zero size. The zero size lets the array expand its length when used with the Array.Add and Array.Remove functions. There is no need to check if an array is none before setting its value. | |||

That way it will overwrite any elements that had been set via creation kit. If you do a check first, it will not overwrite the changes made in CK, but only initializes it if it is empty.[[User:Shirakami|Shirakami]] ([[User talk:Shirakami|talk]]) 2016-09-26T18:44:14 (EDT) | |||
