I need grav. in my game so I want to know how. I have one characters class and I will have 4 Object classes. (As in ground stuff.)

Oh I forgot I need to detect collisions on all 4 sides too! I looked at the Greenfoot API but couldn't make sense of it.

Okay I don't know how much you need but here is one way to work around the problem. First of all put a fall method in your act() 
public void act()
{
     if (notOnGround())
    {
         fall();
    }
}
The notOnGround() would have to detect wether the hero/player what ever is on the ground (please tell me if you need help with that too). The fall code could be very simple and look like this: 
public void fall()
{
     setLocation(getX(), getY() + 1);
}
Though I have seen some people on this site using acceleration and stuff to make the fall look more realistic. For the collision part I would like to know what you mean exactly. Is it platforms, the world edges or something else you want to check collision with?

There are platforms plus bricks in the middle of the world to jump on and stuff.
