Hi,

Thanks for the help for my previous problems.

Now I need some help about how to change a SFFloat format to SFString
format ?

I want to display the speed of a car in TEXT, but the output of
eventOut is in SFFloat format stype,, how can I change it to SFString
in order to input set_string eventIn.

Thanks in advance for replies !

There is a .toString() function in ECMAscript.

#VRML V2.0 utf8

DEF Script1 Script
{
eventIn SFFloat float1_in
eventOut MFString mstring1_out
url
[
"java script:

// eventOut MFString mstring1_out //

function float1_in(value)
{
// value SFFloat
var r = Math.round(value * 10) / 10;
mstring1_out = new MFString(r.toString());
}
"
]
}

DEF TimeSensor1 TimeSensor
{
loop TRUE
}

ROUTE TimeSensor1.fraction_changed TO Script1.float1_in

}

ROUTE Script1.mstring1_out TO Text1.set_string
