As you see, my code does not work. When armor1 is true, it would add my life. goldA is another class.

public void goldenArmor(GameContainer gc, StateBasedGame sbg, Graphics g)
    {
        if(armor1==true)
        {
                goldA.life = life;
                goldA.intelligence = intelligence;
                goldA.power = power;
                goldA.lifeLeft = lifeLeft;

                goldA.head();
                goldA.body();
                goldA.legs();
        }

    }

My other class:

The life, intelligence, power, lifeLeft are nothing but to use it as just reference to prevent stack overflow. And at my main class, it becomes my real booleans, int, doubles. How do I fix this? It does not add it to my normal int.
