We need to see any (and all) code related to adding and removing the actor to and from the world. That would include your world constructor (or 'prepare' method; or whatever code initially adds the actors to the world) and probably the Arrow class code, as I did not see anything to remove actors in the classes given above, First and foremost, copy/paste the exact error message you were getting (clear the terminal before running the scenario and copy the whole message).

Thanks

@Danpost: No, you didn't hurt my feelings at all. But rather I was attempting to express awe at your superior method in a humorous way, which didn't work out so well. :P

jahama, the UserInfo class can be used to store player-specific data which persists between sessions (page refresh etc). Take a look at the documentation for it.

Too late, the assignment was due @ 11:55. But this will probably be on the quiz tomorrow. Thanks

Thanks, it works. I made lastEnemyHit an int variable that increases as Hero makes contact with an enemy. When it hits a certain value, it plays the code. The whole thing is an if-statement.

'getWorld().score();' will not work, either. The score() method is not located in the 'World' class, but in the sub-class of World that HayleyG created. I will use 'WorldName' to refer to that sub-class of World. <Code Omitted>will access the score() method.

You could use the GreenfootImage methods getWidth() and getHeight() and then perform your calculations with them.

how does one go about doing that? and will the data be lost when traveling to a different world?

Here is a collection of a lot of scrolling engines.

Remove line 18 in the GameBall class, it is closing the class and the compiler cannot interpret the following lines because they are not what is expected at that point.

lulzy lulz Just about all of my games involve this frame mechanics (although it is only with my later works that I implement the static global variables) involving multiple images for actors (alongside the additional framechange variable). But then my stuff isn't as nearly as great as yours...
