to stop an Actor from passing through walls, first create a variable to store x and y: private int x; private int y; the method is: public void stopAtWalls() { if (getOneIntersectingObject(Wall.class) != null) { setLocation(x,y); } else { x = getX(); y = getY(); } }

Here is what your new class should look like:

Erm, can you show an example of the code you are using that is not working, as it should work, if I am understanding your explanation correctly.. There is no reason for there to be brackets around move();.

Yay! Thank you, Penguin-man!

First thing to do is to create a variable to store X and Y values. private int x; private int y; you can use any method to move that you want, for example: if (Greenfoot.isKeyDown("right")) { setLocation(getX() + 5, getY()); } the stop at walls method should look like this public void stopAtWalls() { if (getOneIntersectingObject(Wall1.class) != null || getOneIntersectingObject(Wall2.class) != null) { setLocation(x,y); } else { x = getX(); y = getY(); } }

There really is no problem with clearing the world. If in the hero class: <Code Omitted>This saves the location of the hero and saves a reference to the world; then removes all objects, creates the new area and re-inserts the hero at the same location it was removed from.

Make sure your bracketing is proper. If not resolved, post your class code.

You will have to somehow keep track of the current state of the actor; whether it be a boolean that holds a true/false value of the state 'isSick' or a String that holds the current name of the file the image of the actor is set to. The value of this new field can then be used to determine if the actor is currently sick. It will have to be set to 'true' when first contracting a mikrobe.

OMG... never mind. Share button. LOL I feel like one of my students.

Change <Code Omitted>to <Code Omitted>

<Code Omitted>I condensed the code so it would not take so many lines (I had to properly indent the code anyway, so I could check the bracketing). You do no

it is ! .. but it doesnt work

In your 'Background' constructor, add the statement that adds the new object to its world.

Thank You. Actually the problem is so simple, I'm surprised I didn't figure it out! Oh well :/
