Hi all,

i have a code fragment I am referencing (credit given below) and I would like to use a returned value from it in the main draw.

However, it doesn't seem to be returned ,  except as zero perhaps. it's the calculateTextHeight below that I want. It would seem to be returned as textHeight unless I am wrong.

I'm using the below fragment in a class called Node, and am calling other values from the class in draw, but this one has me stumped.

It's a float if that matters, but I feel I am doing something basic wrong.

//from steven http://processing.org/discourse/beta/num_1195937999.html
int calculateTextHeight(String nodeString, int specificWidth, int fontSize, int lineSpacing) {
 String[] wordsArray; 
 String tempString = ""; 
 int numLines = 0;
 float textHeight;
 wordsArray = split(nodeString, " "); 
 for (int i=0; i < wordsArray.length; i++) { 
 if (textWidth(tempString + wordsArray[i]) < specificWidth) {
 tempString += wordsArray[i] + " ";
 }
 else {
 tempString = wordsArray[i] + " ";
 numLines++;
 }
 } 
 numLines++; 
 textHeight = numLines * (textDescent() + textAscent() + lineSpacing); 
 return(round(textHeight)); 
 }
}
