使用ProcessingJS将返回值从一个函数传递到另一个函数的语法？

Question

With ProcessingJS, I have a function that determines a number that I would like to give to another function:

int number;
int theNumbers() {
  // calculations for number

  int number = 10; // sample number
  return number;
}

void mousePressed() {
  // calculations for aLongNumber

  // pass theNumbers() number value
  theNumbers();
  long numberLong = aLongNumber + (number * aLongNumber);
}

For some reason, right now numberLong = aLongNumber and doesn't add (number * aLongNumber) because number has yet to pass to mousePressed() after calling theNumbers();

Answer 1

Try this and see if you get the required results:

int number = 0;
int theNumbers() {

number = 10; // sample number
return number;
}

void mousePressed() {
number = theNumbers();
long numberLong = aLongNumber + (number * aLongNumber);
}
