Recieving an unexpected token error on my collision attempt

Jeremy_Ortiz88

My apologies guys, I know that I've posted questions in regards to this subject before and I think I'm headed in the right direction, I am recieving an unexpected token error in my code. It's highlighting my "int tempxpos" variable. Can someone inform me what may be the problem, much appreciated.

Ball b1, b2;
int mouseClick=0;
String msg;
int steps = 20;
int difx, dify;
void setup() {
  msg="";
  b1 = new Ball(mouseX, mouseY, 50);
  b2 = new Ball(mouseX, mouseY, 50);
  size(600, 400);
}



void draw() {
  background(0, 153, 0);
  fill(255, 255, 255);
  b1.update();
  fill(0, 0, 0);
  b2.update();
  textSize(20);
  text(msg, 0, height-5);

  if (mouseClick==0) {
    b1.xpos=mouseX;
    b1.ypos=mouseY;
    msg="click twice to place the ball";
  } 
  else if (mouseClick==1) {
    b1.xpos=mouseX;
    b1.ypos=mouseY;
    fill(255, 255, 255);
    b1.update();
  } 
  else if (mouseClick==3) {
    msg="click to shoot";
    difx = b1.xpos-b2.xpos;
    dify = b2.ypos-b2.ypos;
    b1.xpos-=difx/steps;
    b1.ypos-=dify/steps;
    b1.xpos+=5;
  }

  if (mouseClick==2) {
    msg="click to place the eight ball";
    b2.xpos=mouseX;
    b2.ypos=mouseY;
    b2.update();
  }
}

  mouseClick++;

CTRL+T is your friend! You're missing a bunch closing curly braces in your class Ball! 3:-O

Another tip, leave blank lines among methods. Makes much easier to read your code! >-)
