Some logging messages were still being issued when portals/debug/logging was false. This could be annoying in games that stream in parts of levels and repeatedly call `rooms_convert()`.
This PR allows all but essential logging to be disabled.
In order to properly support the resource sharing paradigm, Occluders are split into Instances and Resources in the VisualServer. Instances are owned by a Scenario, and Resources are global. OccluderShape resources can now correctly be shared by multiple OccluderInstances.
Due to an optimization to prevent processing except when camera rooms changed, the ticking synchronization and updating of previous and current lists could get out of sync for affected objects, leading to missing gameplay notifications.
This PR adds new paths to properly support and synchronize objects in this "room based" path.
The gameplay monitor wasn't being unloaded correctly in between levels. This meant that exit signals were not being sent, and entered signals for the new level were being missed.
This PR sends appropriate exit signals on unloading, and clear the data.
Previously a crude metric was used to decide on the roaming expansion margin, but it created unexpected results in some scenarios. Instead this setting is exposed to the user via the RoomManager, allowing them to tailor it to the world size, room sizes, roaming objects sizes and the speeds of movement.
Sphere occluders are now tested for self occlusion. Spheres that are behind another sphere in the current view are superfluous so can be removed, cutting down on the runtime calculations.
AABBs are now maintained for Occluders as well as individual spheres, meaning a bunch of occluder spheres can be frustum rejected as a block.
Add framework for supporting geometrical occluders within rooms, and add support for sphere occluders.
Includes gizmos for editing.
They also work outside the portal system.
Fixed a bug in the complex PVS generation which was causing recursive loop.
Move some of the settings out of RoomManager into Project Settings.
Allow PVS generation method to be selected from Project Settings, and control PVS logging.
This PR makes the 'convert rooms' button permanently on the toolbar and accessible whichever node is selected, so you can convert rooms without having to select the RoomManager first.
It also adds a togglable item 'view portal culling' to the 'View' menu which is a simple way of setting the RoomManager 'active' setting without the RoomManager being the selected node.
Both of these have keyboard shortcuts, which should make it much faster to reconvert rooms and edit.
In addition there the string in the 'Perspective' Listbox is modified to show [portals active] when portal culling is operational, for visual feedback. This is updated when you change modes, and when the rooms are invalidated.
Portal margins were not being correctly sent to the PortalRenderer from the SceneTree, so all margins were being used as default (1.0). This PR fixes this.
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.
