From what I can tell from what was given, getRandomNumber appears to be an undefined variable. Also, the expression for the if condition looks to be an int value, not a boolean one (which is required for a condition). Another problem is the previous line which is just a loose int value -- it is like coding a line like: <Code Omitted>or <Code Omitted>(both uncommented) which is really equivalent to <Code Omitted>a non-operative statement. Create a local int variable and assign the random value to it:

Basically, you are wanting to make two buttons, which are, in essence, text display actors that clicks are detected on. Please refer to my Value Display Tutorial scenario.

Yes -- and no. The setPaintOrder method can be used to have ALL of one type object showing over ALL of another type. Otherwise, there is no documented way of doing it. Currently, however, objects more recently added into the world will show over those objects already in the world. This means you can take an actor and remove and re-add it into the world to have it show above another actor.

With what you have given, I cannot see any reason for what you say is happening. The only strange thing I see (which I cannot expect to be related to your issue) is the exclamation mark inside the filename of the image -- and that may be fine, as is.

Remove the counter and add a boolean to track the state of the "space" key. Check for a change in the state of the key by comparing current state to previous state (held by field). When a change is detected, update the field and check its new value to determine when to shoot.

The first line was moved outside the method so the values can be retained (not reset every time the method is called). The second line was added to track the (last known) state of the "space" key. Line 6 checks to see if the state of the key had changed (either just pressed or just released). Line 8 updates the tracking field when a change in the state of the key is detected. Line 9 reverses gravity if the new state is the down state (ju

Actors use setImage and worlds use setBackground. However, I doubt you want this particular image to be tiled on your world's background. You probably should create an actor, give it this image to use and add it into the world. Another option is to use setText on the world; however, then you will not be able to control color, font and size.

the problem is fixed now, i did the commenting thing but that wasnt what fixed everything.. for some reason i just needed to right click the class in the main screen and click new StartWorld(). not sure why that happened but atleast now i know what to do in case it happens again, thanks for the quick response dan

In what class is the code given placed into? Line 3 looks like it takes an object of one type and places it in a field that holds a different type.

Remove those two lines you just added. Below in 'public Sky()', modify these lines: <Code Omitted>

I think you want: <Code Omitted>

In liine 4, what does 'level.getLevel()' do?
