VRML: ROUTE as a parameter in PROTO
I have a PROTO of some object with TouchSensor and I'd like to link different ROUTEs to it when creating objects
e.g. I have
PROTO plate[]
{
Shape {..something..}
DEF TS TouchSensor {}
}
I want to call
plate{ROUTE ...}
plate{ROUTE ...}
with different ROUTEs, but having one PROTO
How to implement this?

You would use IS
to expose the event from the TouchSensor in the prototype.
For example:
#VRML V2.0 utf8
# First, define the prototype "plate".
PROTO plate [
eventOut SFTime touched
exposedField SFVec3f translation 0 0 0
]{
Transform {
translation IS translation
children Shape{
appearance Appearance {material Material {}}
geometry Sphere{}
}
}
TouchSensor{touchTime IS touched}
}
# Then create one or several instances of the object
DEF plate1 plate{translation -2 0 0}
DEF plate2 plate{translation 2 0 0}
DEF myscript Script{
eventIn SFTime receive_event
url "javascript:
function receive_event(){
trace('A sphere was clicked');
}
"
}
# Each instance had a different DEF name, so you can choose where to send the event independently from each other
# but for the example, I send them both to a script that says in the console when it was clicked
ROUTE plate1.touched TO myscript.receive_event
ROUTE plate2.touched TO myscript.receive_event
