The best thing to do is to keep them off the walls: (1) move (2) if intersects wall, move back

One more thing needs to be dealt with. We need to remove the healthBar of the zombie before removing the zombie. So the 'act' method should be more like this: <Code Omitted>

Another thing -- with the code as it is written (referring to the last 'if-else' segment), you have no movement to the pinball after contact with the bumper. It will just rotate in place (it will still be on the bumper on following act cycles).

OK, thank-you. Completely forgot about the tutorials!

No, as I've said, it's unlikely that you'll see a measurable cost to function calls.

Add an instance boolean field to the class for tracking the state of the button -- call it 'buttonDown' (or you can be more specific and give the button name in the field name; like 'spaceDown' or 'xDown'). The two conditions for incrementing on a button down action would be (1) the 'buttonDown' field is currently 'false' and (2) the 'isKeyDown' method returns 'true'. The two conditions for the button up action would be (1) the 'buttonDown' field is currently 'true' and (2) the 'isKeyDown' method returns 'false'. In both 'if' blocks, you will change the value of the 'buttonDown' field and i

The value of the constant CELL_SIZE in your Ground class is declared with an assigned value of 20. My last post shows ways you can use to have that value accessible to other classes.

Maybe you do not understand the reason behind my last comment. If you do not set anything to the image fields ('image1' and 'image2') then what do you think would happen if you tried to set one of them as the image for your actor?

This message, 'invalid method declaration return type required', is trying to tell you that you need to include type declarations to the elements within the round brackets. When the compiler reads this line (line 22 above), it recognizes that you are declaring a method or constructor. It will then need to know certain things about it so it can direct the calling statement(s) to it. Mainly, it needs to know the name of the code-block and the order and type of the arguments passed to it. I have never seen literal values as arguments -- only have I seen variable names (with thei

Yes your code worked. Made it so that when the Humvee hits the side now it gets "teleported" to the other side of the screen. Thank you so much for helping

You need to draw the lines on the world background to produce the edges of the cells (horizontal and vertical lines gapped by the value of CELL_SIZE pixels). The default background image of the world has a default drawing color of WHITE, so it will need to be changed before drawing the lines.

Right. Thanks for the information :)
