Hi,

I need to dynamically create a button and within this button, I need to detect the TouchSensor and perform according. How do I include a script inside another script? To create the button dynamically, I use createvrmlfromstring and within I need to include a PROTO.

Example :
.......
url "vrmlscript:
function set_time() {
newvrml = 'DEF ' + node_name + ' Transform {';
newvrml +='translation 0.6 0 0';
newvrml +=' children [';
newvvrml+=' TouchSensor{}

......

createvrmlfromscript(newvrml);

I need to implement script to handle TouchSensor. How can I do it. Any idea?

When doing the createVrmlFromString, it return nodes, and you can
access those nodes for either storing them, copy its properties,
adding a route or, the most common, adding it to the scene.

This might be what you're looking for:

Viewpoint{}

DEF brain Script{
field SFNode self USE brain
eventIn SFTime touched
eventOut MFNode addChildren
url "java script:
function touched(){trace('Clicked !');}
function initialize(){
nodes = Browser.createVrmlFromString('TouchSensor{}
Shape{appearance Appearance{material Material{}} geometry Box{}}');
Browser.addRoute(nodes[0], 'touchTime', self, 'touched');
addChildren = nodes;
}
"
}
ROUTE brain.addChildren TO gr.addChildren
