MEL array weirdness

[bigfatMELon]

Can you post your entire Do/While loop? There isn't enough info here to figure out how you are getting that result.

Sure, here is the source

//declare variables for the rotate x and y values

float $initalx = 0;
int $pike_count = 0;

seed (1);


do {

float $rotx = `rand 0 78`;
float $roty = `rand -30 30`;
float $trans = `rand .5`;


//create cone
string $pikes[] = `polyCone -r 1 -h 2 -sx 3 -sy 1 -sz 0 -ax 0 1 0 -tx 1 -ch 1`;

//scale into shape of pike
scale -r .088 10.001 .076;

//move pivot to base of pike
xform -ws -piv 0 -10 0;

//move pike to groundplane
move -rpr -y 0;

//duplicate with random xy transform
//duplicate -rr; move -r 1;

//rotate in the x and y axes to tilt forward and to side
rotate -ws $rotx $roty 0;

//add one to $pike_count
$pike_count ++;


print $pike_count;
}
while ($pike_count < 10);

umm... I don't see any place where you are gathing up $pikes to print it. The way you have it now everytime your do while loop runs it resets $pikes with the new results from polyCone.

If you wan to keep an array with all of the names of the objects you create in your loop, I'd do it like this:

string $allNames[];
int $pike_count = 0;

do{
//create cone
string $pikes[] = `polyCone -r 1 -h 2 -sx 3 -sy 1 -sz 0 -ax 0 1 0 -tx 1 -ch 1`;

// add this name to the array
$allNames[size($allNames)]=$pikes[0];

//add one to $pike_count
$pike_count ++;

}
while ($pike_count < 10);

print $allNames;

Thanks for the reply it is exaxtly what I needed. Could I trouble you to tell me what exactly the following line does?

// add this name to the array
$allNames[size($allNames)]=$pikes[0];

I am familiar with using size () and I see that it does the job I need it to do but how is it going about doin it? I would look it up in the docs but the syntax is such I am not sure what to look up : )

Thanks again for your help!

the result ead like this:

Put the first item of $pikes into $allNames at the index position that is one larger than the last one in that array. Array indexes start at zero, so the following works:

$pikes[0] = "this is the first position";
$pikes[1] = "this is the second position";
$pikes[2] = "this is the third position";

Now, if you don't know what the next available position is, like when you are adding things to an array within a loop, you need a while to assign data to the next available spot in the array. Conveniently, the size of the array will always point to the next available index because indexes are zero inclusive. Using the array we created above:

size($pikes);
//3

There are three items in the array and the last item is index #2, so that brings us to:

$allNames[size($allNames)]=$pikes[0]

Thanks for the details! I get it now :)

I just started a search and was directly linked with this thread!
I was searching for
relationshipPanel1RightAttrFilter

this nodes get created when I execute my UI Script!

This is what creates a panel:

string $camera = `columnLayout -adjustableColumn true`;
string $subTestcam = `frameLayout -w 600 -h 600 -mw 0 -lv false -bv true -bs "etchedOut"`;
string $testcam = `modelPanel -l "Facial Controlls" -cam "front1"`;
modelEditor -e -grid 0 $testcam;
setParent $camera;

weird!
