Hello

Has anybody got idea how to extract single char from
MFString?

I tried this:

#to field into incoming data from counter = 1,2,3,...n
#from field out single char should be send to string field in Text node
#all ROUTE under script (not shown) are OK

DEF GeneratorTextu Script {
eventIn SFInt32 into
eventOut MFString out
field MFString napis ["some char for checking generator"]
url ["java script: function into (value){
out = new MFString( napis[value] );
}
"]}

But ISDN {It Still Does Nothing), cortona show string "undefined"

thanks in advance

napis[value] is the value.th string of the napis, but napis currently
have only one string.

For cosmoplayer, i have success with

function into (value){
out = new MFString(napis[0].charAt(value));
}

http://www.web3d.org/x3d/specificat....html#TableC.23

| Table C.23 -- MFString property

| Property
| Description
| numeric length
| property for getting/setting the number of elements

Use arrayvariable.length for that. An example:

----------
#VRML V2.0 utf8

Script{
field MFString myStrings ["jjj","ll","lki"]
url "java script:
function initialize(){
trace('Number of rows: ' + myStrings.length);
trace('First row: ' + myStrings[0]);
trace('First character: ' + myStrings[0].charAt(0));
trace('First 2 characters of the third row: ' + myStrings[2].substring(0,2));
}
"
}
