final static function class<Object> GetLastOverrideFunctionClass(class<Object> c, Name FunctionName, optional out Array<class<Object>> IteratedClasses)
/*
    Returns closest script Class in parent chain of script Class "c" that overrides Function/Event named "FunctionName".
    IteratedClasses Array is used to prevent calling function multiple times on same script Class.
    Usage examples:
    GetLastOverrideFunctionClass(class'Hat_NPC_MetroCreepyCat_FoodShop', 'OnInteractedWith') -> class'Hat_NPC_MetroCreepyCat_FoodShop'
    GetLastOverrideFunctionClass(class'Hat_NPC_MetroCreepyCat', 'OnInteractedWith') -> class'Hat_NPC'
    GetLastOverrideFunctionClass(class'Pawn', 'OnInteractedWith') -> None
*/
{
    if (FunctionName == '' || c == None || IteratedClasses.Find(c) > -1)
        return None;
    IteratedClasses.AddItem(c);
    if (DynamicLoadObject(PathName(c)$":"$FunctionName, class'Function', true) != None)
        return c;
    if (c.default.ObjectArchetype == None)
        return None;
    return GetLastOverrideFunctionClass(c.default.ObjectArchetype.Class, FunctionName, IteratedClasses);
