You need to explain what behavior you want for the forcefield -- how it should react with other objects (like the enemies). As is, the behavior is that the forcefield will move diagonally up and to the left quickly with each enemy in range. It could end up moving as much as two-thirds across the screen in under half a second (with just one enemy).

Please read >this<. (Hint: you can use getOneIntersectingObject or one of several other methods for this.)

As far as deleting all the images manually placed -- no. Just re-compiling the project will remove them. As far as the code -- there was no mention in the instructions of any randomness; also, if they are to be placed horizontally across the top and across the bottom, there would be no change in the y coordinate for either the Me or the Face objects and dividing vertically by 8 has no bearing on the placement unless you want to use that value to place the rows of objects at that distance from the top and bottom edge. The 'for' loop parameters you are using will only produce 7 objects; t

Even with the fix the test question is still wrong. :/

The problem is that the 'move' method provided by the Actor class has the signature 'move(int)' while the one in the Animal class has the signature 'move()'. You can use 'move(int)' from any Actor subclass (including the Animal class) because that method is defined in the Actor class; for the same reason, you can only use 'move()' from any subclass of Animal (or from the Animal class itself, since it is an editable class).

Line 3 creates a new Hero object and line 4 tries to get its x coordinate in a world; however, it has not been added into any world (you may have a Hero object in the world, but it is not the same Hero object referenced here).

You might be interested in the java tutorial trails. The second section on the left titled Trails Covering the Basics would be a good place to start.

setRotation(getRotation()+5); or just turn(5);

x=0; y=4; x=y+3; // x = 4+3 = 7 x=x+2; // x = 7+2 = 9

thank you i got it

Okay, thank you! :)

Or more simply: <Code Omitted>As an alternative to this way, you could put the following in your world class constructor: <Code Omitted>and then the deer will detect clicks on themselves without the crosshairs being in the way.

Ohhhhh thank you :) It all works now.

The '-5' is not overriding the rule. It is an adjustment to the current transparency value: <Code Omitted>At this point, 't' is just an integer value, not a transparency value. <Code Omitted>This line checks to see if that value is less then zero. The value is set to zero if found below zero before actually setting the transparency of the image. To make an object blink, you need a timer. I think Super_Hippo just replied to someone about this.
