But that does not do what I want it to do. I have a second actor which is "ball2". 2 of those should be added when bullet touches the actor "Ball". You mentioned using the split method in ball class but the above mentioned split code just creates millions of balls right when I click run.
Sorry. I should have stated that the split method should be as Hippo wrote it above. Adjust it to create ball2 objects as required. If still getting millions of ball2 objects, post entire class codes for review.

My game has a big world. The image goes to the right and left. But when i place my testperson und you walk in one direction, he moves out the image. So my question is, is it possible that the world moves with the charakter?
Please refer to my Scrolling Tutorial scenario, which refers to a class that is demonstrated in my Scroller Class Demos scenario.

I have been trying to figure out how to do something like ray casting but I ran into a problem

By Triangluminati, with no replies.
For starters I just started learning to code about 4 or 5 months ago for my school so I'm sorry if I get terminology or something wrong. I have been trying to learn how to code ray casting in Greenfoot so I can apply it to the project I have been working on. I have been following a tutorial somewhat (https://sinepost.wordpress.com/2012/06/16/raycasting/) but I have been trying to come up with my own solutions in areas. I have gotten a useable, but not very playable, version of ray casting to work but the rays have to travel far enough that once they reach an object, the distance between them is so large and the result comes out very blocky/chunky. My main question is if there is a way to shoot out more rays to make the objects appear more smooth or if there is a different approach to reach the same effect. I will add my code here for my player:<Code Omitted>and I will add my world code <Code Omitted>

This might just be a stupid mistake by me, but I cant for the love of god figure out why it does not work. In the following code, I made it so, if my "Bullet" object, touches either the Edge or the "Ball" class, it should get removed, but for some reason it just stays?
Is the remove method being called from anywhere? If so, from where? If not, then why not?
As I thought im just Stupid lol. I had to call the remove method. works now, thanks.

Thanks a lot to both of you @RcCookie can it be also written as <Code Omitted> ?
No, because Button is not the interface with one method. But you could write <Code Omitted>

the program's not creating my world
<Code Omitted>and <Code Omitted>The iterators, i, remain at zero (no increments given). So, it is stuck in a loop. World object never completes initializing. In fact, Key objects are created for the first white key multiple times, repeatedly, until memory runs out, whereby you will get a OutOfMemoryException.

Screen change

Last reply by danpost, almost 3 years ago:

But do you know a way I can add a world on a world? Like a little screen on my current World?
Two ways to do that (at least). One is to create a world whose background mimics the real world, like in a paused state. It is not a world in a world, but it could be made to appear as such. Another way, which does not involve another world altogether, is to just use an actor for the "little screen". Just have all operations suspended while that actor is in the world. For further details, just ask.
