When editing the rules in the inventory of a structure or dino, a 'hint' is displayed in the top center of the window to provide guidance as to how the structure will behave in general. There are limitations that may cause it to not behave as expected. However, the hint is good at understanding the general behavior.

There are nine possible hint values:

1. Accept All (Overflow)
   
2. Accept All except Red (Partial Overflow)
   
3. Accept All, Reject Red (Partial Overflow)
   
4. Accept Green
   
5. Accept Green, Else Ignore
   
6. Accept Green, Reject Red, Else Ignore
   
7. Accept Green, Else Reject
   
8. Reject All (Drop Box)
   
9. Idle (Ignore All)

In the following explanations, the following phrases will be used:

Explicit Accept Rule is a rule in the middle for either a resource or folder with Green letters.
Explicit Reject Rule is a rule in the middle for either a resource or folder with Red letters.


This is a passive configuration where the inventory will accept any known item, provided there is capacity and the inventory does not prohibit that class of object.


This is a passive configuration where the inventory will accept any known item other than those that have an explicit reject rule defined and the inventory does not prohibit that class of item and there is capacity to accept it.


This is an active version of the above but it also will actively attempt to move the items with explicit reject rules out of the inventory if there is an available target with capacity.


This is a passive configuration where the structure will accept any of the items that match the accept rules and that there is capacity and the inventory does not prohibit that class of item.


This configuration is similar to the previous configuration.


This is an active configuration where items with reject rules are pushed out to target inventories that can accept them while only accepting items with explicit accept rules. Any other items are ignored.


This is an active configuration where the items with explicit accept rules are accepted while all other known items are pushed out if there is an available target.


This is an active configuration where all known items will be pushed out if there is an available target that can accept them.


This is a configuration where the rules are disabled. In general, to disable a structure, switch it to Disabled instead of this to preserve the rules.
