i have been involved in learning vrml on my own since the last 5 years
and my unofficial teachers have been you all....thanks a lot..ive
learnt so much from the questions already posted that i ner had to
come out in open...

...but a small problem forced me too....could you please tell me whats
wrong wid this code..

...all i am trying to do is to highlight a location by drawing a
sphere whose radius increases wid time...something wrong in the SCRIPT
i know.....

THANKS in advance

Try this:

DEF SCRIPT Script {
eventIn SFTime timenow
eventOut SFVec3f scalenow
url "vrmlscript:
function timenow(value) {
scalenow = new SFVec3f (Math.round(value)*4, Math.round(value)*4,
Math.round(value)*4);
}"

Renember the name of the function must be the same as eventIn and not
eventOut. Do not forget the ';' at the end of lines. The values that
can be transported by the routes always a value and a timestamp of the
value (timenow ist the function and not the value).
