I don't know if I should create another post on this but is it possible to create a highscore leader board using the scores. So I have a MainMenu world and I created a button that says Highscore and when its pressed it takes you to the HighscoreScreen World. I want the leader board to be in this world. If it is possible do you mind teaching me how to do it. Thanks

Thanks! Works like a charm!

Well, you call methods on m before you check if it is null. You have to check ‘m != null’ before calling getX() and getY() on it. <Code Omitted>

If using showText, you will not be able to unshift the text. If using an actor, creating the image by way of the GreenfootImage constructor with a String parameter, the you can vary its position in the world so that the left edge of its image is always at the same place. The other way would be to draw the text image in the above on another image large enough for any input string given by the user; thereby maintaining the same image size and keeping the text left-aligned. I guess a fourth way would be to draw the text image directly onto the background image (so, not usin

Okay sorry, apparently I didn’t read your first post carefully. Didn’t notice that the code was available. I looked at your code and I can tell you what’s wrong with it. You code does remove the enemy. It is not really efficient or easy to read, but it does remove it. The problem is that the world has a list of all skeletons and is constantly updating the location so they correctly move with the background when that moves. The following code (line 142–144 in class “ground”) reads: “if the skeleton isn’t in the world, add it”. And that’s what’s happening. It is removed and then, in the next a

Okay, thank you!

Yeah I'm not great at this at all haha. Thanks for your help mate

It works without throwing an exception in the terminal, but there's still the issue of currentIndex not increasing at all within Calculate class, and a new issue of ... Never mind, I made a couple small changes while typing this message which fixed these issues. All I had to do was change '//world.updateDisplay();' from a comment to code (in button class) and add 'Calculator world = ((Calculator)getWorld());' a couple lines above it. For some reason, hitting an operator throws an exception, but I haven't tried resolving that issue so I'll post another reply if I'm having difficulties wit

superb thank you

Actually, I think I got it! Thanks!

Changing the state (image, in this case) of one Player object does not do the same to all Player instances. You need to change the image of the one player already in the world (not create a different Player object and change its image; as well, that one was never put in the world, so its image is immaterial). Replace your first two lines with this: <Code Omitted>

thank you! it works.

Your Soldier class has one constructor. The one with a bunch of parameters. The subclasses should have a constructor which exists in the super class. So you could either create a constructor in the Soldier class without parameters. And/or the subclasses constructors should match. So the constructor of your Heavy class could look like this.

Apparently, rand is alternating between 0 and 1 inside the do loop, making x add and subtract; add and subtract. You need to be very careful with loops and make sure that they will eventually, at some point, be broken out of. Unfortunately, your coding is (1) undocumented; (2) bulky, and not easily readable; and (3) unfactored; -- making it virtually impossible to see what is going on (especially for an outsider). All I can say at this point is that you need better control of the flow within the loop. A visited cell should not be re-visited.

Thank you so much!!!!
