Properties

Public property FdUrl: TMFString read FFdUrl;
 
Public property Initialized: boolean read FInitialized write SetInitialized default false;

Initialize / shutdown of the script. Read this to know current script state, write this is to actually initialize/shutdown if needed.

Note that the script node doesn't initialize itself at any point. Reason: there's no comfortable moment to do this: 1. in constructor some routes and such are not initialized yet, and we should initialize script after whole VRML graph is loaded. 2. tricks with BeforeTraverse, like used for TInlineNode, are not Ok, since scripts must work even when they are in the inactive part of VRML graph.

If you want scripts to work, you have to initialize them yourself. If you use TCastleSceneCore, this will be done for you automatically when you change TCastleSceneCore.ProcessEvents, so it's not a problem in practice.
