Fucntion input
Apr 26th, 2010, 2:31am  
This one has me scratching my head.... I can use the code below like I want, it counts from one number towards another.

How can I place this code into a single function????
I would need to pass the result of the function back to the function....... I feel like my answer is recursion. I just need a nudge in the right direction. I know that what I want is a Python generator but I don't think Java has anything similar.

void setup(){
 size(200,200);
 background(255);
 frameRate(10);
}

int x=100;
void draw(){
 x=towards(x,10);
 println(x);
}

int towards(int current ,int target){
 if(current!=target){
   if (current <target){
     current=current+1;
   }
   else {
     current=current-1;
   }
 }
 return current;
}
