Class TAbstractTouchSensorNode

Event generated when we register a "click" on the shapes within the same group as this TouchSensor node. The "click" definition corresponds to the X3D touchTime event generation.

Note that, in order to register clicks, TCastleScene must be configured to process events (TCastleSceneCore.ProcessEvents) and be able to detect clicks on particular shapes (TCastleSceneCore.Spatial should contain ssDynamicCollisions). Usually you will initialize scene like this:

MyScene := TCastleScene.Create(...);
MyScene.Load(...); // load X3D graph with TouchSensor node
MyScene.Spatial := [ssRendering, ssDynamicCollisions];
MyScene.ProcessEvents := true;
