View Full Version : Using pointPosition

I stored a name of the selected object using-
string surfaceName[] = `ls -sl -o`;

then later on in my script, i wanted to store the position of a random vertex on that object mentioned before using pointPosition -
float $vertPos[] = `pointPosition $surfaceName.vtx[$randomNum]`;

However it returns with,
"Error: Too many arguments. Expected 1, found 2"

I know it has something to do with using $surfaceName as it works if i type the actual name of the object instead. But i need to be able to use this script with any name.

Any ideas?

Thankyou

You need to catenate the data stored in the variables together int one string, like this:


float $vertPos[] = `pointPosition ($surfaceName+".vtx["+$randomNum+"]")`;


Try that out.

when i use that, it returns

" Error: Illegal operation "+" on data type string[]. "

$surfaceName is an array, you want to concatenate to some string in that array. To do that you'd need to index it:

float $vertPos[] = `pointPosition ($surfaceName[0]+".vtx["+$randomNum+"]")`;
