@Laurence, start a discussion thread on this. Show your complete world class and Lamp class codes and explain the problem and what the fix should do.

@Laurence, if the actor points in the direction of the cursor, then the beam will also. The beam will always follow the "source" actor and point in the same direction that actor faces.

You cannot download this scenario as the source was not published. However, you can view the code used in the two main classes by clicking one of the buttons near the bottom of the scenario window while it is running.

@Sepho, you cannot download any scenario that the one who uploads it does not allow for it. When uploading a scenario, a checkbox in the sharing dialog box determines whether the source is made available or not.

@GameCounts, you cannot download any scenario where the user does not upload the source. You could ask that freddy_siagian upload the scenario again, this time including the source; but, doing so is entirely up to that user.

@ReggaeCheeseMan, it does not work on the site because the scenario tries to write to a file which an applet is not allowed to do for security reasons. You need to download it and open it up in greenfoot to check it out.

@Tanonic, you should probably start a new discussion thread on this. Show the code you are using for placing the actors in the world and the movement code of your main actor.

Why does this take so long to load??? You have no music files and the three questions are always the same -- so it is not like you need a whole bunch of images.
