精灵正在绘制错误但正确的位置

Question

public void render() {
if (TimeUtils.nanoTime() - lastSpawn > 2100000000)
            chooseLane();
}

private void spawnCar() {

        Rectangle car2 = new Rectangle();

    float Pos123 = MathUtils.random(0, 2);
    if (Pos123 == 0) {
        car2.x = 60;

    }
    if (Pos123 == 1) {
        car2.x = 180;

    }
    if (Pos123 == 2) {
        car2.x = 300;
    }

    car = new Rectangle();
    car.width = 100;
    car.height = 172;

    car2.y = 1000;
    car2.setWidth(100);
    car2.setHeight(172);
    carb.add(car2);
    lastSpawn = TimeUtils.nanoTime();

}

精灵每次都在这三个位置中的一个位置进行绘制但是当我执行System.out.println(Pos123)时，精灵与它产生的实际车道没有关联。这也是将碰撞探测器扔出去的打它，因为它在错误的车道中触发
