Instance Methods
(void)	- onActiveBuildingFocused:
	Called when camera enters a building's bounding box.
(void)	- onActiveBuildingLeft
	Called when camera leaves all buildings (no building bbox contains the camera).
(void)	- onActiveSublocationChanged:
	Called when the active sublocation (floor) of the focused building changes.

Detailed Description

Listener for outdoor scenario when camera focuses on a building or leaves it.

Definition at line 18 of file NCBuildingListener.h.

Method Documentation

onActiveBuildingFocused:

- (void) onActiveBuildingFocused:

(nullable NCBuilding *)

activeBuilding

Called when camera enters a building's bounding box.

Parameters

activeBuilding

The building that is now focused.

Swift code snippet:

    func onActiveBuildingFocused(_ activeBuilding: Building) {
        // [swift_Building_getSublocations]
        let floors = activeBuilding.getSublocations()
        print("Focused building, floor count: \‍(floors.count)")
        // [swift_Building_getSublocations]
 
        // [swift_Building_getActiveSublocationId]
        let activeFloorId = activeBuilding.getActiveSublocationId()
        print("Active sublocation id: \‍(activeFloorId)")
        // [swift_Building_getActiveSublocationId]
 
        // [swift_Building_setActiveSublocationId]
        activeBuilding.setActiveSublocationId(activeFloorId)
        // [swift_Building_setActiveSublocationId]
    }

Objective C code snippet:

- (void)onActiveBuildingFocused:(id<NCBuilding>)activeBuilding {
    // [objc_Building_getSublocations]
    NSArray<id<NCSublocation>> *floors = [activeBuilding getSublocations];
    NSLog(@"Focused building, floor count: %lu", (unsigned long)floors.count);
    // [objc_Building_getSublocations]
 
    // [objc_Building_getActiveSublocationId]
    int32_t activeFloorId = [activeBuilding getActiveSublocationId];
    NSLog(@"Active sublocation id: %d", activeFloorId);
    // [objc_Building_getActiveSublocationId]
 
    // [objc_Building_setActiveSublocationId]
    [activeBuilding setActiveSublocationId:activeFloorId];
    // [objc_Building_setActiveSublocationId]
}

onActiveBuildingLeft

- (void) onActiveBuildingLeft

Called when camera leaves all buildings (no building bbox contains the camera).

Swift code snippet:

    func onActiveBuildingLeft() {
        print("Camera left all building areas")
    }

Objective C code snippet:

- (void)onActiveBuildingLeft {
    NSLog(@"Camera left all building areas");
}

onActiveSublocationChanged:

- (void) onActiveSublocationChanged:

(int32_t)

activeSublocationId

Called when the active sublocation (floor) of the focused building changes.

Parameters

activeSublocationId

New active sublocation id.

Swift code snippet:

    func onActiveSublocationChanged(_ activeSublocationId: Int32) {
        print("Active floor changed to sublocation id: \‍(activeSublocationId)")
    }

Objective C code snippet:

- (void)onActiveSublocationChanged:(int32_t)activeSublocationId {
    NSLog(@"Active floor changed to sublocation id: %d", activeSublocationId);
}
