Your java control panel needs to first allow java content to be shown; as well as needing security level at 'High' (not 'Very High') and 'http://www.greenfoot.org/' needs to be added to the 'Exception Sites' list. All these setting are in the 'Security' tab of the java control panel.

NEVERMIND, found a rogue statement that was setting finishedDialogue to true when it shouldn't be. All fixed.

Open up the greenfoot application and load your project. Then, use the menubar and select "Edit/Import class...". Finally, select the SmoothMover class and click on the 'Import' button. As an alternative to using that class, you could just save the original location of the bullet and add a step counter as follows:

Thanks it works now

You need the java security status on 'High' -- not 'Very High'. You also, on the same panel, need to have the checkbox that enables Java content in the browser checked and 'http://www.greenfoot.org/' in the Exception Site List.

If you are talking about the scoreboard that uses the UserInfo class, then the problem is that the latest updates on java have tighter security and the UserInfo storage server is not accessible to the scenarios on the si

Thank you!

Oh, I got it working! Thank you so much Dan! I'll probably ask more questions a bit later after I do a few more things with the game. Thank you!

The only way the Crab class would show up in the "Other classes" area is if you removed what class it extended or changed it to something other than Actor or World. Just make sure you have the class extending the Actor class. If you have issues with bringing it back, post the code for the class so we might be able to tell what is happening and why it is not showing up where you want it to.

Thank you danpost :)

@SPower, I see where you see an assignment symbol ( '=' ) in place of a conditional equality symbol ( '==' ); however, it will never actually change the value there as it was just set to 'true' in a previous line. What this means is that the question does need to be asked. Removing lines 9, 10 and 14 will not change what the code does. Also, a timer is not what ZacBuzzsaw is going to need -- a boolean field is indeed what is wanted (like the 'isShot' field), but the way it is used is incorrect (hence, its name is also misleading). The field should track the state of the "space" key or shou

Thanks for your help, I ended up using a solution similar to the one found in this thread: http://www.greenfoot.org/topics/200 BTW, lines 11-15 do not work without a method, the linked thread uses a for loop to do something similar.

I appreciate that - you do great work and so many benefit from your contribution to teaching future programmers.

For one thing, once the method has completed its execution, the 'bg' variable is lost. By creating a new GreenfootImage object, you are not dealing with the image returned by the use of 'getBackground'. but making a copy of the background image.

The 'shoot' method in the Alien class is not being called at all. You should probably have it called from the act method under some random condition.
