• Script Node
  Scripts allow the developer to perform logic and process events.

DEF TOGGLE Script {
    eventIn SFTime toggle
    eventOut SFInt32 which 
    field SFInt32 thisVal 0                                
       behavior "
          function toggle() {

                 thisVal = 0;                                   
             else 
                 thisVal = thisVal+1;
          which = thisVal; 
      }"
},

• Switch Nodes
  Events in switch representations

  DEF SWITCH Switch {
    whichChild 0
      choices [
