Part 2: Learning About Widgets with VRML

"Finishing Up" >Page 1, 2

Let's put it all together in a single file. Now our masterpiece button cube file looks like:

#VRML V2.0 utf8

Background { 
#note that this Background example is copied from VRML 2.0 Source book a great VRML reference
   skyColor        [ 
   		0.0 0.2 0.7,
		0.0 0.5 1.0,
		1.0 1.0 1.0 
		] 
		skyAngle [1.309, 1.571 ]
		groundColor [
			0.1 0.1 0.0,
			0.4 0.25 0.2,
			0.6 0.6 0.6
			]
		groundAngle [ 1.309, 1.571 ]
   }
   
   Transform {
	   translation 0 0 -4
	   children	[
		   DEF ELMO TouchSensor {}
		   Shape {
               appearance Appearance {
                     material DEF WHITE Material {
                              diffuseColor 1 1 1
                     }
               }
	
               geometry Box { }
           }
		]
	}

	DEF	LIGHT  PointLight {
	location 3 0 0
	color  1 0 0
	on FALSE 
	}

DEF ToggleScript Script { 
    field SFBool value FALSE 
    eventIn SFBool set_boolean 
    eventOut SFBool value_changed 
    url "javascript: 
        function set_boolean( bool, eventTime ) { 
            if (bool == false ) { return; } 
            if (value == true ) { value = false; } 
            else { value = true; } 
            value_changed = value; 
    }" 

} 

ROUTE ELMO.isActive TO ToggleScript.set_boolean 
ROUTE ToggleScript.value_changed TO LIGHT.set_on

Next week we're going to actually make this thing look like and act like a switch!
