Greenfoot On-Screen Test Part 6 - Adding a Counter 

do u wanna meet up??

Arthur B that's great news, really pleased for you, well done!

good luck, this gunna be harder than the paper 1

Can confirm, was on the bench earlier

Zuthandrapus best of luck!

Update on the exam, WJEC sent a message to the invigilator to tell us not to do question 9 at all - question 9 is the Greenfoot question. This because somebody messed up the code for the counter

Zuthandrapus no they told centres to use the wrong version of Greenfoot

Woozle 03 Productions Check you haven’t got another piece of code decrementing the counter somewhere. Compare the code carefully. Also make sure you are not adding the counter every time something happens otherwise the default value of zero will be implemented.

Jaden Hercules You must have made an error because as you can see from the video it works.

Yeah, what had happened was I didn't have an actor for my counter which was my mistake. Not sure if it's working now, but I'll let you know once I go to my class.

Jaden Hercules Great, good luck!

Nevermind I found the problem. My problem was that I used different code so as to remove the icebergs. Thanks for this.

Oisín O'Connor Same I’m so confused

I know it’s been 2 years but help me please

cardaroy you need to create the getCounter method in the world class

Vladiboy I’ve got the same problem, and I’ve created the method In world

Same

@@Vladiboy This worked for me. Thank you.

@@Vladiboy where do I add this code in my world or the ship please help I have the same problem

feel free to add your response as a helpful point

declare 'score' in the counter class (before any method) public int score = 0; then just add these lines to the main actor's class (at the bottom of the act method) Counter counter = (Counter) getWorld().getObjects(Counter.class).get(0); counter.score = counter.score + 1 if you need to take away score (e.g a secondary actor taking away score if it collides with the main actor) then simply put those lines into the secondary actor's class and change the + 1 to - 1

KillaElectriix- im getting a nullPointerException error, should I be putting 'new' anywhere?

GEITH ABDUL MAJID use the method in this video, works just fine.

Mr A Heard -I tried the method in the video but there is one problem: in my main actor where I typed "Counter counter = Ocean.getCounter ();" there is an error on "getCounter" that says non static method getCounter() cannot be referenced from a static context.
