I can normally turn, move, and fire at the same time but it does not work while using the left key. << Code Omitted >>

It may just be a keyboard thing, Try a different key combination (maybe use 'x' instead of 'e').

I'm creating a program that contains multiple instances of an object. These instances spawn in a while loop and I want to say if ANY one of those instances is touching object x then do delete all further instances which I plan to do by using the break method in the loop. The problem I'm finding is that there is no direct way to say if ANY of the instances are touching object x. I was wondering how you guys would work around this problem.

Let me get this straight. You want to stop creating these object once any placed into the world ends up touching this object x.

Help with collision system

As I understand it, clone() copies all object fields exactly. But Actor keeps an internal identifier number, so clone() copies that identifier. Using clone() is almost certain to mess Greenfoot up, as it assumes each actor has a unique identifier. Instead, write a copy-constructor that copies the state you want.

I'm trying to create two drop down menus - one for month, one for day, to input a birthday. I found some posts about how to create a drop down menu, but none of them will run on my computer because they're from older versions of greenfoot, I guess. Can anyone help? (Also I'm literally terrible at this so please be patient.)

My latest scenario, Smooth Mover Demo, contains a DropDownMenu class and has source available. I also recently uploaded a Calendar Actor Class

I do not see anything wrong with your code. Maybe you already have a Score class (??). Or, maybe there is a hidden character in your code the compiler does not like (try deleting and retyping white space around that line).
