Class TCastleVector3Persistent
Unit
Declaration
type TCastleVector3Persistent = class(TCastleComponent)
Description
TVector3 record represented as a TPersistent descendant, to be able to visually edit it (in Lazarus and Delphi visual designer, and Castle Game Engine visual designer) and to serialize it.
Normal user code does not need to deal with this class or it's instances. Instead directly operate on TVector3 values, which is faster and more natural. TVector3 are simple records, so they are naturally copied on assignment, and various operators like additions work in a natural way too.

This item has no description. Showing description inherited from TCastleComponent.ValueIsStreamed.
Whether the current value of this object should be written to the stream. This should be This is used by CastleComponentSerialize, which is used in Castle Game Engine for all serialization. In simple cases, this just says whether the current value of this object equals to some default value. The default implementation of this class returns Descendants that override this to sometimes return The name of this method is consistent with TPropertyEditor.ValueIsStreamed in LCL. | |
