So now I have my addedToWorld() code written up: << Code Omitted >> I also know that the world(Water) class should call the object into existence, so my question is how would I call it into the world class

Looks like an infinite loop waiting to happen. If line 9 assigns any number other than zero on the first time through the do loop, the condition to repeat will never be false. I am not sure how your code will prevent the actors from moving toward the corner they are placed in at times, although the chance is somewhat low. I was thinking you should h

That game seems quite helpful. Is there anyway I could see the code for it?

Run the scenario. Click on buttons (ground platforms -- "Where", "What" and "Who" buttons).

The class code itself should have one pair -- one (opening bracket) after the class declaration line and one (closing bracket) at the end of the class. Each method, likewise, should have one pair -- one after the declaration line and one at its end. Any and all local code blocks (for iif, for, switch, do, while, etc) should have one pair -- one at the beginning and one at its end. Any and all excess brackets must be removed (see lines 24 and 50).

Apparently, you need to subtract from the timer to increase game time (which is what I presume you want to do). There is insufficient information to help any further.

How do I auto generate an ID using arrays? And how do i create a freight status for each freight order?

I just thought it was required to store the number in the array and have it auto incremented. This is what I attempted although I know it is completely wrong << Code Omitted >> I just cant seem to understand how I should auto generate and increment a freight ID as well as create a freight status for every new order. Thanks for any help in advance

Hint: the assignment is asking you to describe an object; that is, create a class that creates freight order objects. It will have an ID and a status (as fields). The value of these fields should be assigned during th

Looks like you are missing a class closing squiggly bracket at the end. If you indent properly (use Control-Shift-I, on Windows), you might spot it easier.

Problems with getOneIntersectingOnject

Last reply by RcCookie, 14 days ago:

You are right with the classes, I´m not that good at java just jet. Also, my problem was solved simply by adding these brackets around the "getOneIntersectingObject()" and adding the "(Surface)". I knew the problem with the nullPointExeption though. Thanks a lot, RcCookie
