Never mind I figured it out I just went into the world class and edited the size so never mind.

thanks guys :)

maybe if(Greenfoot.getRandomNumber(100)<10){ } or what do you mean?

Do you have a reference to an Actor named 'lorry' declared in the class? What is the code to the 'BinBump()' method?

thx

ok, so put all the lookforsmting() stuff into eat thx

make a variable to store the x and y values of the object that you don't want to go through the maze private int x; private int y; the method to make it stop at walls is simple public void stopAtWalls() { if (getOneIntersectingObject(Wall.class) != null) { setLocation(x,y); } else { x = getX(); y = getY(); } }

Thanks for all the suggestions, I'll go with splitting height in images since I can implement that fairly easy but is still quite good.

The easiest way is to instantiate a different world that shows the title page and waits for the enter key to be pressed, when the crab world would then be instantiated.

The Java tutorials - this page has all the links neccessary to get you on you way in learning the language. The second section on the left 'Trails Covering the Basics' is the place to start. There is also a link to the API documentation a little bit down on the right side in 'Other Resources'. Greenfoot Documentation - this page has links to instruction on using Greenfoot; plus links to videos and the Greenfoot API.

Line 7 compares a class with a number. Obviously, that cannot be done; hence the error. You need to compare the number with the size of the list of items of that class that are in the world. <Code Omitted>Lines 2 and 3 are not needed at all.

Thank you so much for your help :)

@Peach, it might be good for you to review the Java Trail; Learning the Java Language. The section on 'Classes and Objects' explains how to write methods. The section 'Language Basics' has most of what you will need to get started in programming.

If the compiler cant find the variable wormsEaten you haven't declared it or you have declared it but somwhere (probably in an othere class) where you cant find it from your worm class. Have you got a variable wormsEaten somewhere? If yes show us the code then we can help you.

The name of your lobster object is 'lobster2'. The class name that the object was created from is 'Lobster'. You cannot set the location of a 'class'; only an object. Try the following <Code Omitted>The line 'Lobster.setLocation(390,200);' tries to set the location of a class. The line'Lobster2.setLocation(28,546);' tries to set the location of an undefined object (Lobster2 is not lobster2 -- Java is case sensitive).
