Put a check in the Dart class, first determine its distance from where the mouse was clicked and set its location there if within one move of the location. If not that close, do the normal move (use an 'if-else').

For a smooth movement you just need to use double values instead of int values for the location of the players. If you have a look at the class Player in Operation: Crash Test you'll find what you need. Just use the class Player as the superclass and it should work.

You could have something like this: <Code Omitted>

Thank you! Worked great!

You should be creating objects for the world in the world constructor or a 'prepare' method that it calls. You would use something like 'new Platform(100, 300)' to create a Platform object that will move vertically between the two values given.

Thank you it works! You are BEST!

sorry im quite new, what does that mean?

It works! :) Thanks for help!

Look at my scenario and just copy the explosion code : http://www.greenfoot.org/scenarios/8371

A simple class for a scolling textbox might look like the following:

The problem with the code is what I have made bold: if("c".equals(Greenfoot.getKey())){ newBomb(); }else if ("x".equals(Greenfoot.getKey())){ newBullet(); } You are calling 'getKey' twice within the same act cycle. The second call will always return 'null'. So, what you need to do is save what is returned the first time in a local field and use its value for comparing. <Code Omitted>

Then you should set the location of the coins to the other edge of the world: <Code Omitted>
