Description

Methods

Public constructor Create(const AX3DName: string = ''; const ABaseUrl: string = ''); override;

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

Constructor. Initializes various properties:

  • Name, BaseUrl are initialized from given parameters.

  • The Fields, Events lists are filled in every descendant, to have all the fields/events defined by the specification.

  • DefaultContainerField, and other node-specific stuff, is filled in descendants. This is actually implemented in CreateNode, that is called at the end of this constructor.

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

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

Public procedure CreateNode; override;

This item has no description. Showing description inherited from TAbstractChildNode.CreateNode.

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 FdAutoOffset: TSFBool read FFdAutoOffset;

Internal wrapper for property AutoOffset. This wrapper API may change, we advise to access simpler AutoOffset instead.

Public property AutoOffset: Boolean read GetAutoOffset write SetAutoOffset;

This item has no description.

Public property EventTrackPoint_changed: TSFVec3fEvent read FEventTrackPoint_changed;

This item has no description.
