Sorry. I was mistaken in the above. The check on line 10 limits the number of tiles that could be detected to two -- which will not work. The other tile detected will be the tile that the character is current at. If you import java.util.List into the class you can replace my lines 10 through 12 above with the following:

Thank you soooo much! I was close on my own, but just couldn't get there!

Thanks so much for your help.

I was suggesting something like this: <Code Omitted>

Thank you danpost, this solved my problem!

If you want to pause the whole scenario, you can use 'Greenfoot.delay(200);'. This will be like 3-4 seconds with the speed slider in the middle.

Thanks. The reference soulution is way better...

If you are referring to your 'Bee' scenario, it seems okay to me. It is also showing your score of '40'.

I think my Use of 'this' demo may be something for you to look at. Basically, what the scenario demonstrates, as far as world changing, is that you can create all your portal pairs and place them each in their respective worlds right at start-up. Randomly placing the portals in their worlds will not effect their capabilities and they can be made to be one-way, circular (back and forth), or chained (one to the next). Also, when used, the receiving portal can remain (as I have it in the demo), be relocated, or even removed. If you have an

You could get a MouseInfo object if 'mouseClicked(null)' and then see if 'getActor', if not null, returns an actor of said type. However, I would just keep references to all three colonist objects in the world class and check for clicks on each one in its act method:

There are other problems as well -- but, the main one is where you are putting the code. It should not be in the Animal class, but in your World subclass and called from the constructor of that class. Also, a better name for the method might be 'addObjects' (plural), since it adds multiple actors into the world:

UPDATE: The problem has been fixed, thanks all for replying. There was an extra letter in the "Level" subclass that didn't belong. Sorted now.

@azazeel: I think this code was given and you have to find out the value of 'sales'. If you change the given code like you did, you will get a different result. @ipeefreely: You used 'bonus0' in the code above. If 'bonus0' is 0 or 'bonus', then at the end, 'bonus' will be 20. The reason is the following: 'if (sales>300)' checks if 'sales', which is 500, is greater than 300. It is, so it executes the if-block (which is the next line). So 'bonus' is set to 'bonus0+20'. The next condition isn't even checked because it has this 'else' before the 'if'. That means it would only check the conditi

I wonder this myself. This is what I see: <Code Omitted>Your line 48 and 49 get some random numbers that are not being used; so line 46 through 50 are meaningless. Besides, the actor would have to come in contact with two Zuko object at one time for line 46 to detect one because you are removing one in the previously calle

The code will not compile as 'sum' and 'x' are not declared anywhere. However, if you had this: <Code Omitted>then sum = 0+2, +3, +4, +5 = 14. I believe that this would work also: <Code Omitted>In fact, this may even work: <Code Omitted>
