Make sure that the object you want to turn to, is in the world. Or the list is empty and you can't get the first object from an empty list.

Oh, thank you for your help, in both cases. :)

yeah even after I do that its still blank. The first time, it worked though.

What class is line 71 supposed to be initializing? What happens if you just remove that line (is it really needed, there)?

ty for your quick replay

Line 15 in the Nyawa class will only set the value of 'nyawa' to '1' when the project is compiled (because you have made it a ''static' (or class) field. As such, you need to set its value either during the construction of the world or during the construction of the Nyawa object..

Thanks, Danpost! Your're a life saver! Thanks!! I really appreciate your help!!

Oh, I see. This makes things a lot easier and more flexible, I understand where I went wrong. Thanks Dan,

Thanks but we got it sort of fixed already. Appreciate the feedback!

I cannot see how you are getting that error on that line, especially considering the condition before it (line 4) and that no action is taken between that and the next previous line (line 3) where you assign 'x' its value. However, an improvement that will probably solve the issue is that you really do not need that particular condition on line 4. You can just use this: <Code Omitted>

No. But you can make your world smaller to fit the monitor size and scroll the background image using program code.

Did you review this page?

There are a couple of ways (at least) to improve the direction of movement. Probably the best one is to track the location and rotation of the actor using finer units of measure (rather than units of whole pixels and whole degrees). The SmoothMover class provided with greenfoot provides a finer coordinate system, but does not provide finer rotation. My QActor support class, however, provides both. It can be found in my Asteroids w/Improved QActor class scenario.

Thank you!
