24	<!-- To make the lamp go on and off, a TouchSensor is routed into a 'toggle' script that alternates between TRUE and FALSE outputs, sending TRUE on the first TRUE input, then FALSE on the next TRUE input. These TRUE/FALSE values are routed into a SpotLight node within the lamp, turning it on and off. -->
25	<!-- A second script converts an incoming TRUE or FALSE in to one of two colors. Those colors are routed into the lamp's bulb to change it from an on color to an off color. -->

Event Graph ROUTE Table entries with 8 ROUTE connections total, showing X3D event-model relationships for this scene.

Each row shows an event cascade that may occur during a single timestamp interval between frame renderings, as part of the X3D execution model.

LightSwitch TouchSensor isActive SFBool	→ ROUTE event to (1)	Toggle Script set_active SFBool	then	Toggle Script on_changed SFBool	→ ROUTE event to (2)	LampLight SpotLight set_on SFBool
			then	Toggle Script on_changed SFBool	→ ROUTE event to (2)	ColorSelector Script set_selection SFBool	then	ColorSelector Script color_changed SFColor	→ ROUTE event to (3)	BulbMaterial Material set_emissiveColor SFColor
