Based upon this scenario http://www.greenfoot.org/scenarios/20781 How can i tell greenfoot to write down the best scores to an EXCEL file? Thank you!!

Locally, the UserInfo class stores data to a 'csv' file which Excel opens and works with. On the site, data is stored to a database on another server.

Distance Comparisons

Is there a way I can compare distance so I can give the dart a target based of that instead of only targeting one actor or the other?

By "based on that", do you mean by which one is closer? Does your World subclass keep references on the players? Will both players always be in the world? What are the class names involved? Show code for class of dart.

HELP!!!!

First, you need some kind of list to hold the key sequence (probably a character array, aka: a String object, would do nicely). Then, you need an int to track the progress of the playing of the sequence. When the sequence is to start, set the int field to the length of the sequence. This way, when the int field is zero, the sequence is not playing and when it is not, the sequence is playing. When the int field is greater than zero and either the field value equals the length of the sequence or the current note is not playing, (call a method to) play the note and decrease the int field (no

thanks though. and do you have a youtube channel on coding for greenfoot

No -- just the two tutorials uploaded here. Most of your other recent posts were answered by my last post (without code -- but quite straightforward). The walls also can be set when you save the world.

[Help Needed :)] Changing the Actor target of a troop

does that mean that when I remove the resource with getWorld().removeObject(this);, the resource still exists, but is not in the world?

As long as a valid reference exists on the object, it will not go to the gc. The field 'currentTarget' references the actor (even if removed from the world). Think of when you create an object, before it is added to the world. It must remain or you would never be able to do anything with it. The only thing removing it from the world does is (1) remove its reference from the list of actors the World object keeps; and (2) set

Greenfoot.ask() causing number format exception (null)

By temch55, with 1 reply.
Replied to by danpost, almost 8 years ago:

That is crazy, because for the last half hour or so I was working with just that -- using Greenfoot.ask in a constructor. I had not come across any issues with it; however, I have not yet closed out and opened it again. It may just be that without some world already having been created, it has no width to place the text in, thereby disallowing it. I say this because I did change my world to a (1, 1, 1) size and it did set the input box to the previous width size. I am glad you came across this because I was about to inform someone else that it would actually be possible, where this proves
