Portal Exit
Portal Exit: Exits for items leaving Subsystems
When an Item has to leave a subsystem to go to the screen above, it needs a place to leave inside the portal.
The Portal Exit provides passage to the screen above, where the item will appear at the Portal object.
A Portal Exit is created automatically for every sub system screen, which in turn is created when a Portal object is added to a model.
The Portal Exit is much like a normal Exit, but instead of it destroying items it returns them to the screen containing the Portal object associated with the sub system screen it is on.
Portal Entries are for items entering Subsystems.
All subsystems must have at least one Portal Entry and one Portal Exit.
No interaction editing is necessary for Portal Entries and Portal Exits.
Portal Exit States
Idle Portal Exits always appear as idle.
They can however have different icons selected for them.
Portal Exit Object Editing
The following object menu options are available in a Portal Exit.
Menu Item
Description
Up To Portal
Enables the user to switch the screen display "up" to the Sub-system screen containing the Portal Object that owns the current subsystem.
Attributes
Attributes can be added to a Portal.
Click on the Attributes option brings up a list of Attribute names for editing, or enables you to name a new attribute.
(This option is also at the Portal Entry and the Portal itself).
Connect To
This option lets you select from a list of objects the one you want to assign to this Portal Exit.
Items entering th portal from this object will now appear always at this Portal Exit.
When you assign an object to a Portal Exit, its name appears above the Portal Exit. Note that an outside object with a leading underscore in its name will not be displayed.
Many Portal Exits can be linked to "Any".
When there are numerous paths of the same class leaving a portal, Portal Exits set to "Any" (i.e. no specific target object) will send items out of the subsystem along the first flow (lowest numbered path) or first-created appropriate track leaving the Portal, that will accept the item.
Portal Exits that are connected to a specific object will NOT allow an item to take alternate paths, or objects when the connected object is blocked.
Add Alternate Entry
Places a new Portal Exit on the screen for you to use.
Each can be assigned as the link to a specific object outside the subsystem, using the "Connect To" menu option.
