The use of special prefixes is only actually required during the import phase - the first conversion of rooms, roomgroups, and portals from Spatials and MeshInstances (based on the workflow of importing from blender).
Once converted to the native Godot nodes there is no longer a need for the naming requirements.
This PR removes the requirements except for the import. Manual portal linking after the initial conversion is now done exclusively using the `linked_room` nodepath property of the Portal.
Due to a quirk in CSG Shapes, updating is usually deferred to the next frame. This is problematic as we need to read back the geometry on the first frame when converting levels.
This PR adds a function to CSGShape to force immediate updating (if dirty), and calls it during room conversion.
The default autoplace algorithm places instances in the highest priority Room. It became apparent that there are some situations in which users will want to override this and force placement in a Room from a particular RoomGroup, especially an "outside" RoomGroup.
This setting allows the user to specify a preference for Room priority. When set to 0, the setting is ignored and the highest priority Room is chosen.
Although explicit portals did a check to detect internal portals, this check was missing from autolinked portals. This meant they were incorrectly clipping the room bounds of the enclosing outer room.
This PR adds a check for internal rooms during the autolinking and sets the internal flag where needed.
The default portal margin is stored in the RoomManager. Previously this was propagated to Portals when the value was changed, and Portals each stored this default value.
This caused a bug during loading, if the RoomManager was loaded before Portals, the value was never propagated.
This PR makes the default margin a static value stored in the RoomManager, and the Portals now read directly from the static value when required, and do not store locally. This gets around the problem.
Due to an oversight in the autoplace recursive search for static objects, static objects were getting added twice to the portal renderer, which meant they were being rendered twice, lowering performance.
This PR corrects this horrendous error.
Allows users to have the RoomManager as the roomlist.
Fixes a couple of bugs dealing with situations where users attempt to link Portals to Rooms outside the roomlist.
Adds a PortalEditorPlugin allowing you to flip individual portals.
In order to make level building easier, the system can now support STATIC and DYNAMIC objects in the roomlist that are not placed in rooms. The system will automatically place them in the appropriate room.
It turned out the new autolinking feature was linking portals AFTER the static meshes had been added to rooms in the PortalRenderer. This meant that large meshes weren't being sprawled across these portals. The fix involves doing the autolinking BEFORE adding the static meshes.
Fixes a bug in the warning for portals being in the wrong direction, they should have only been checkout for outgoing portals. This was resulting in erroneous warnings.
Also the room conversion logs are refined to be more compact and informative.
A warning icon is also added in the gizmo for portals where autolink fails.
