Need help saving world instances when moving to new worlds

Alright. Btw, line 15 doesn't do anything since you are doing the same thing in the next line again. And if you change the 'coastalFrame' in line 16 to 'this', you can also remove line 10 ;)

how to make a swing object?

By williandutras, with 3 replies.
Last reply by danpost, almost 10 years ago:

You probably need to double the width or height of the image for the rope. Try this in the Rope class constructor ('public Rope()'): <Code Omitted>This will work if the image of the rope at zero rotation is hanging straight down. The code takes the original image and draws it on an image frame that is twice as tall, moving the point of rotation to the top of the original rope image.

The game does not what I want.

I had the same problem, and I figured that there is an error in the exporter, where it doesn't also bundle external .jar libraries as well. The libraries in question for me: <Code Omitted> I suspect that any external libraries are not being packaged into the jar

How to save and intersecting object?

By nathe2000, with no replies.

I am making a game where a "knight" will go up a lane and attack another object, like Clash Royal. My issue is that I need it to attack and the way that I thought of to do it was to save the object that the knight intersected with first, then have another method that would get that object and reduce its health. I don't know how to save the object that the knight intersected and how to get its health variable. This is my code so far...<Code Omitted> Any help would be appreciated. Thanks!

My code won't work

By Lars2501, with 1 reply.
Replied to by Super_Hippo, almost 10 years ago:

The 'size' method returns a number, not a boolean. You could check if the number is higher than 0. Or you could use the 'isEmpty' method.

Calling a method from within itself is not something you should do without great care (as coded above, the calling of the method will continue indefinitely, causing the project to throw an exception); anyway, Super_Hippo said to call the method from the constructor -- not from the method itself.

Didn't realize i added setup() there actually thats my bad, i figured it out for the most part though thanks for the help guys

Need help with code for World

By Lars2501, with 1 reply.
Replied to by danpost, almost 10 years ago:

A single equal sign, '=', is an assignment operator; and you cannot assign a value to a method call. The operator you need to use is the conditional equality operator, which is a double equal sign, '=='. Also, the 'ready' method, which returns a boolean value (or any method that return anything) must have a 'return' statement. I believe the method should read: <Code Omitted>
