How do I use methods from the World?
Ups, I accidentally posted it.
Well, I just write it here:
and then how can an actor use this void?
I tried
but this doesnt work
public class world extends World
{
GreenfootSound backgroundmusic= new GreenfootSound("backgroundmusic.mp3");
public void bgstart()
{
backgroundmusic.playLoop();
}
...getWorld().bgstart();
You can use this:
which will allow the compiler to find the method in your 'world' class (as opposed to only looking in the 'World' class, and Object class, for it).
However, as the background music is something you would want global access to, you could change line 3 to:
and then, you can use:
from anywhere.
((world)getWorld()).bgstart();
static GreenfootSound backgroundmusic= new GreenfootSound("backgroundmusic.mp3");world.bgstart();
Oh yes thanks, I found the exact same way you wrote I time ago in another discussion
This works, thanks
