[Processing3] joc labirint

Salut ! Recent am inceput sa invat sa lucrez in Processing3 si am o problema cu o aplicatie pe care incerc sa o fac.

Jocul urmareste sa muti cursorul de pe spatial rosu pe spatial verde al ecranului, evitand obstacolele. Problema este ca functia care verifica sa nua tingi obstacolele ( sau impelmentarea ei) nu este buna.
Are cineva ceva idei?

Obstacle1[] obs1 = new Obstacle1[100];
Obstacle2[] obs2 = new Obstacle2[100];
int n=30;
float x, y, d1, d2;
boolean touch=false;
void setup() {
  size(1024, 768);
  background(50);
  for (int i =0; i<obs1.length; i++) {
	obs1[i]=new Obstacle1( x, y, d1, d2 );
  }
  for (int i =0; i<obs2.length; i++) {
	obs2[i]=new Obstacle2( x, y, d1, d2 );
  }
}
void draw() {
  if (touch == false && mouseX < width-100) {
	//desenare background
	background(50);
	fill(255, 0, 0);
	rect(0, 0, 100, height);
	fill(0, 255, 0);
	rect(width-100, 0, 100, height);
	//bila in jurul mouse-ului	
	stroke(255);
	strokeWeight(5);
	noFill();
	ellipse(mouseX, mouseY, 15, 15);
	//afisare obstacole
	strokeWeight(1);
	for (int i =0; i<n; i++) {
	  obs1[i].display();
	  obs1[i].move();
	}
	for (int i =0; i<n; i++) {
	  obs2[i].display();
	  obs2[i].move();
	}
  }
  //conditie castigare joc
  else if (touch==false && mouseX >= width-100) {
	background(255);
	textSize(180);
	fill(0);
	text("YOU WON", 100, height/2+90);
  }

  //conditie pierdere joc
  else /*if (touch==true)*/ {
	background(255);
	textSize(180);
	fill(0);
	text("GAME OVER", 100, height/2+90);
  }
}
void collide() {
  for (int i=0; i<n; i++) {
	if (mouseX>obs1[i].x-d1/2 && mouseY>obs1[i].y-d1/2 && mouseX<obs1[i].x+d1/2 && mouseY<obs1[i].y+d1/2);
	touch=true;
	break;
  }
  for (int i =0; i<n; i++) {
	if (mouseX>obs2[i].x-d1/2 && mouseY>obs2[i].y-d1/2 && mouseX<obs2[i].x+d1/2 && mouseY<obs2[i].y+d1/2);
	touch=true;
	break;
  }
}
