Mel Script: Looking for a command if something is selected or not

Fran127

Hi all!
I am trying to do a script who can do two diferent things depending if something is selected or not.
I am looking a command like the “object exists,” let’s say…

if( something is selected ) {
// do this
} else {
// do this instead
}

I think it could be something like this but is not working

if ( `ls -sl True` ) {
print "something selected";   
}
else {
print "nothing selected";
}

I hope some guru of mel can help me with this, I coudn’t find anything on the web

I don't know the answer but I suggest to put [Maya] in front of the title

You are right, Thanks!

you can try this:

string $sel[] = `ls -sl`;<br>if ($sel[0] == "") <br>    {<br>    print "Nothing";   <br>    }<br>else<br>    {<br>    print $sel;    <br>    }

Aw yeah! Thank you very much!!

//checks if object is selected<br>string $selt[] = `ls`;<br>for ($node in $selt) {<br>    if (size(`ls -sl $node`)) {<br>        //node is seleted<br>        print($node + "\n");   <br>    }<br>}

Thanks Tekoppar!
Here is another one I got that I think is more simple and I like avoiding variables for this:

if (size(`ls -sl`))
{
print "yes";
}
else{
print "no";
}

Ah I misread your question, I thought you wanted to check if a specific node was selected or not.

you didnt finish the condition.

{<br>    if (size (`ls -sl`) > 0){<br>        print "yes";<br>    }<br>    <br>    else{<br>        print "no";<br>    }<br>}

There is no need to add the greater than 0. 0 is false and anything else is true. Thus there's no need for the greater than 0

interesting, didn't know thanks for pointing that out.
