## Dev smoke (NEON-28 occluder): action [code]dev_toggle_occluder_obstacle[/code]
|
|
## (default **Ctrl+Shift+K**). Toggles `Obstacle` **visibility + collision** —
|
|
## does not call [method Node.queue_free].
|
|
## Uses [member Node.process_mode] [code]PROCESS_MODE_DISABLED[/code] so the [StaticBody3D] is
|
|
## **removed from the physics simulation**
|
|
## (default [member CollisionObject3D.disable_mode] is [code]REMOVE[/code]).
|
|
## Layer/shape tweaks alone left a **Jolt ghost collider** (invisible wall) in practice.
|
|
## When hidden, reparents `Obstacle` under [member _world]: [NavigationMesh] source geometry scans
|
|
## [NavigationRegion3D] children only ([code]SOURCE_GEOMETRY_ROOT_NODE_CHILDREN[/code]), and the
|
|
## default [code]geometry_parsed_geometry_type[/code] is [code]PARSED_GEOMETRY_BOTH[/code], so a
|
|
## child [MeshInstance3D] still carved a hole even with collision disabled — rebake alone was not
|
|
## enough.
|
|
## After each toggle, rebakes (main thread) and syncs the player [NavigationAgent3D].
|
|
## **F9** / **F10** are debugger shortcuts in the embedded game; use the Input Map action.
|
|
## For a true **freed-node** occluder test, reload the scene or remove the body in the editor.
