next level
so could i do this
if Counter counter = (Counter)getWorld().getObjects(Counter.class).get(100);
{
Greenfoot.setWorld(new Level());
}
If you had one hundred and one counters and you wanted the last one, then yes (I guess that was a bit facetious -- I know you do not have one hundred and one counter objects). You only have one, so 'get(0)' would refer to it. You then need to get the value of the counter object using the 'getValue' method of the Counter class and compare it to 100.
so how do i put together the 'getValue' and
together?
if Counter counter = (Counter)getWorld().getObjects(Counter.class).get(0);
{
Greenfoot.setWorld(new Level());
} thank you! im sorry i just dont quite understand it yet.
but now i get an error?
non static method getValue() - cannot be refrenced from a static context...
what does this mean?
If you cannot put the pieces together with what has been provided up to this point, you really need to review the Java tutorials, especially the trail on Learning the Java Language.
ok

what does this mean?well that just went over my head :s
i have no idea whats going on... :s
what does that error mean..?
/**
* Return the current counter value.
*/
public int getValue()
{
return value;
}
{ if (Counter.getValue() >= 100)
{
Greenfoot.setWorld(new Level1());
}
}plz help...
In line 8, you are using the class name and not an object of that class to get the value from. I repeatedly have shown how to get an instance of the counter class if you only had one in the world.
so would it be...
** 02. * Return the current counter value. 03. */ 04. public int getValue() 05. { 06. return value; 07. } 08. { if (value.getValue() >= 100) 09. { 10. Greenfoot.setWorld(new Level1()); 11. } 12. } There are more replies on the next page.
