how do i limit my scenario so my object cant pass it?
Add another condition, for example: if(Greenfoot.isKeyDown ("W") && y>getWorld().getHeight()/2). Instead of getWorld().getHeight()/2 you can substitute any value.

i have to create a variable with the y? cause its not recognizing the "y" aloneI usually enter the variable y and write x=getX(); as the first line in the object code(x I also create) y=getY(); and then I already use variables, because it is more convenient for me.
i'm a little lost right now
my code look like this
im not very good at progamming im sorry
how do i set the height of the world?
public class buzz extends Actor
{
private int dir = 3;
public void act()
{
if(Greenfoot.isKeyDown("down"))
{
setLocation(getX(), getY()+dir);
}
if(Greenfoot.isKeyDown("up"))
{
setLocation(getX(), getY()-dir);
if (getY()<getWorld().getHeight()/2);
{
move(0);
}
}
}
}
Try this:
//At the class beginning
private final int maxHeight = 0;
//In your act method
if(Greenfoot.isKeyDown(„up“)&&getY()<maxHeight){
serLocation(getX(), getY - dir);
}

Depends on how far up the object should be allowed to movelilshopa wrote...

public class buzz extends Actor
{
private int dir = 3;
public void act()
{
if(Greenfoot.isKeyDown("down"))
{
setLocation(getX(), getY()+dir);
}
if(Greenfoot.isKeyDown("up") && getY()>getWorld().getHeight()/2)
{
setLocation(getX(), getY()-dir);
}
}
}
