First Script Problem

I think you just have some bad sytanx.

// ls returns an array, so the varible you cast it to must be an array
string $selected[];
$selected = 'ls -sl';

// becasue the array could have any number of elements in it
// loop through it and add the attrs
for($i=0;$i<size($selected);$i++)
{
addAttr -ln NiData_ObjectString -dt "string" $selected[$i];
setAttr -type "string" ("collision_" + $selected[$i]) $selected[$i];
}


I haven't tested this, but it should get you pretty close.

Thanks for the help, but it is giving me a syntax error on

$selected = 'ls -sl';

Opps, didn't notice that it's the wrong tick mark.
You should use the back tick (the one by the 1 key) not the single quote.

$selected = `ls -sl`;

Cool that helps, Now it creates the attribute but it is not putting the "collision_object name" in the the field. Here is the error I am getting

// Error: line 10: No object matches name: collision_StreetLights_4 //

Sorry, never really looked that close at how you where setting the attr. The line should read:

setAttr -type "string" ($selected[$i]+".NiData_ObjectString") ("collision_" + $selected[$i]);

That did it thanks alot. Quick question though. You said before that the ls command returns an array, but when I looke up the command it said it returns a string. I am trying to understand how all this works, if you could shed some light on this for me that would be very cool. I guess I still have alot more reading to do on this MEL stuff, but it is very cool so far. Thanks again.

The docs says it returns string[], which is an array ( [] == array).
String is just the type of array, you can also have float[] and int[].

OK thanks, good to know. :thumbsup:
