Description

Methods

Public procedure Activate(const Time: TX3DTime; const ATransform, AInvertedTransform: TMatrix4; const OverPoint: TVector3); override;

This item has no description. Showing description inherited from TAbstractPointingDeviceSensorNode.Activate.

Activate pointing device sensor. Used by the events engine (like TCastleSceneCore) to notify this sensor.

OverPoint indicates 3D point (in global, that is TCastleSceneCore, coordinates) pointed by the mouse.

In TAbstractPointingDeviceSensorNode class, this simply sends isActive := TRUE event.

Public procedure Deactivate(const Time: TX3DTime); override;

This item has no description. Showing description inherited from TAbstractPointingDeviceSensorNode.Deactivate.

Deactivate pointing device sensor. Used by the events engine (like TCastleSceneCore) to notify this sensor.

In TAbstractPointingDeviceSensorNode class, this simply sends isActive := FALSE event.

Public procedure Drag(const Time: TX3DTime; const RayOrigin, RayDirection: TVector3); override;

This item has no description. Showing description inherited from TAbstractDragSensorNode.Drag.

Called by events engine (like TCastleSceneCore) when you move your mouse over the active drag sensor.

Public procedure CreateNode; override;

Create node fields and events.

Public class function ClassX3DType: String; override;

This item has no description. Showing description inherited from TX3DNode.ClassX3DType.

Node type name in VRML/X3D, for this class. Normal VRML/X3D node classes should override this to return something non-empty, and then X3DType automatically will return the same value.

Empty for classes that don't have a hardcoded VRML/X3D node name, like a special TX3DUnknownNode. Such special classes should override then X3DType to return actual non-empty name there.

You usually should call X3DType. The only use of this method is that it works on classes (it's "class function"), without needing at actual instance.

Properties

Public property FdAxisRotation: TSFRotation read FFdAxisRotation;

Internal wrapper for property AxisRotation. This wrapper API may change, we advise to access simpler AxisRotation instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property AxisRotation: TVector4 read GetAxisRotation write SetAxisRotation;

This item has no description.

Public property FdDiskAngle: TSFFloat read FFdDiskAngle;

Internal wrapper for property DiskAngle. This wrapper API may change, we advise to access simpler DiskAngle instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property DiskAngle: Single read GetDiskAngle write SetDiskAngle;

This item has no description.

Public property FdMaxAngle: TSFFloat read FFdMaxAngle;

Internal wrapper for property MaxAngle. This wrapper API may change, we advise to access simpler MaxAngle instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property MaxAngle: Single read GetMaxAngle write SetMaxAngle;

This item has no description.

Public property FdMinAngle: TSFFloat read FFdMinAngle;

Internal wrapper for property MinAngle. This wrapper API may change, we advise to access simpler MinAngle instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property MinAngle: Single read GetMinAngle write SetMinAngle;

This item has no description.

Public property FdOffset: TSFFloat read FFdOffset;

Internal wrapper for property Offset. This wrapper API may change, we advise to access simpler Offset instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property Offset: Single read GetOffset write SetOffset;

This item has no description.

Public property EventRotation_changed: TSFRotationEvent read FEventRotation_changed;

This item has no description.
