View Full Version : Need help - working with vectors.

Hi, I'm trying to write a script at the moment that uses a lot of vectors and I've run into a scripting issue. I need to work with vector arrays but I can't seem to access array elements properly. For example:

This works:
vector $testb = <<1,1,1>>;
print ($testb.x);
//Returns: 1

So does this:
vector $test[3] = {<<1,1,1>>,<<2,2,2>>,<<3,3,3>>};
print ($test[2]);
//Returns: 3 3 3

However, this doesn't:
vector $test[3] = {<<1,1,1>>,<<2,2,2>>,<<3,3,3>>};
print ($test[2].x);
// Error: print ($test[2].x); //
// Error: Line 2.17: Syntax error //

So my question is - does anyone know how to access vector array elements? How about assigning new values to an element (e.g.: $test[2].x = 4)?

Any help would be greatly appreciated. :)

Yup vectors are funny. How about this?

vector $temp = $test[2];
print $temp.x;

?

Hey,

I know of one way to do it, might be more.

But you can create a temp vector variable and place the vector at array X into that.
Might not be best explanation, but here is a code snippet:
--------------------------------
vector $VectorData[] = {<<0,1,2>>, <<3,4,5>>};

vector $tempData = $VectorData[0];
print ($tempData.x);

---------------------------------

not sure how to assign new values to an element though.

Thanks for the idea guys. Yeah looks like vectors are really strangely handled in MEL. :(

I'm finding a lot of limitations in MEL these days that makes me think I should learn how to program in the API.
