public class LoadSensor
extends X3DConcreteNode
implements LoadSensor
LoadSensor generates events as watchList child nodes are either loaded or fail to load.

X3D node tooltip: [X3DNetworkSensorNode] LoadSensor generates events as watchList child nodes are either loaded or fail to load. Changing watchlist child nodes restarts the LoadSensor.
  • Hint: use multiple LoadSensor nodes to track multiple loading nodes individually.
  • Hint: Background is not sensed due to multiple-image ambiguity.
  • Warning: watchList child nodes are not rendered, so normally USE copies of other nodes to sense load status.
  • Hint: use Inline 'load' field to prompt or defer loading.
  • Warning: new X3D node, not supported in VRML97.
  • Hint: example scenes and authoring assets at https://x3dgraphics.com/examples/X3dForWebAuthors/Chapter12EnvironmentSensorSound

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
