oh yeah thanks master

oh, yeah. thanks master,,,, thanks a lot for this tutorial

how come we can help you if there is no specific clue, and you did not give any initial code. please make it a little bit practical. okey let me do my best, 1. make class number using label, import from existing class in greenfoot (provided by greenfoot) 2. make 2 object from label and set it with random number (Greenfoot.getRandomNumber(abc)) 3. show dialog box (Greenfoot.ask( )), and compare the user input against addition of those numbers

You could make your level worlds subclasses of my Level class (a support superclass that facilitates many aspects of a level changing scenario). It is in my Super Level Support Class scenario. It is well documented and will let you know what can be changed and what cannot; as well as what is needed in each of your level worlds (subclasses of Level). Look over the classes within my scenario to get an idea of what is going on. I tried to keep things to a minimum so as not to overcomplicate things as it is being looked over. You will notice

My Bee Quick (ImgScroll Demo) scenario has an ImgScroll class that is used to keep the boy in the middle of the screen while allowing scrolling to the limits of the background image. You can add the class (un-modified) into your project and easily use it. If you look at the Welt class, you will see 5 lines of interest. Lines 18 and 19 declare fields that hold the scrolling engine (scroller) and the main character (boy). Line 32 creates the ImgScroll object and line 38 creates the Boy object and adds it into the world. Both are assigned t

Your issue was due to excessive transparencies in your Red_laser image. The method was picking up one of more than one intersectors (the one that did not sing a bad note); so, the one that was supposed to be removed was passed up. After removing the excess transparency from its image, it seemed to be having no problems with detecting and removing the bad note singer.

Please do not revive old discussions. Start a new one with a short description of the issue in the title. Then explain your issue in detail supplying relevant code and information in the post (read the 'Posting code? read this!' link below the reply box before posting any codes).

Oh okay. It worked. Thank you!

Oh, thanks man. It's working now. :D

Ok thanks :)

Highscore ,which located in world class,nd i wants to access it from where its permanantly stored... Nd i haven't do any code for to store nd retrieve the value bcZ i don't know how to do that..

Maybe you should add a setter method in the world class to set the value of the room variable: <Code Omitted>Then, in your Joe1 class, you can (instead of 'room = 1.4', for example) use: <Code Omitted> Using just 'room = 1.4;' you are only changing the local variable in the method, not the value of the field in the 'fearmine' class.

You have to read out the coordinates first. <Code Omitted>And so on

Oh I think I misunderstood - Greenfoot.getKey() can be null thus calling compareTo on it would cause an exception.
