You need to save which image is currently being shown. Since it’s only 2 images you can simply use a boolean for that: <Code Omitted>Then in your act method, you need to change the current image to the opposite one: <Code Omitted>This however will load an image from a file every frame, which, like you might imagine, is not very efficient. The better way to do this

Is there any other way/action to implement the feature?

It would take some doing to implement it with just the GifImage class. An option is to add my Animation class which allows for a single run through the images. You can find it here.

Sound not working

By AnJoMorto, with no replies.

I have an interactive title screen and was trying that when the player clicks on the character he says a random sentence, one of them being a rare EasterEgg. I got this code after initiating all the sounds with GreenfootSound a = new GreenfootSound("name.wav"); <Code Omitted> After doing this, only the "ee" sound comes out 1/31 times and the rest of the time only silence comes out. Does anyone know why?

explain the preferred access modifier used for both variables and methods

It varies on usage. For example, getter and setter methods are generally public and the fields they deal with are private.

why using setLocation is more practical than using the move() and turn() methods

The argument can go both ways. Depends on how the actor is to move.

Problems with GamePadTemplate in v.3.6.0

By AnJoMorto, with no replies.

I've tried to use the GamePadTemplate proposed in the documentation with Greenfoot 3.6.0, but it seems to be outdated. I always gives me this error message: java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$PlatformClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$PlatformClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap') at GamePad.<clinit>(GamePad.java:98) The line where at GamePad.java:98 is : final URLClassLoader cl = (URLClassLoader) parentCL; Has anyone else encounter this problem and find a solution or is there a new way to connect a game controller to a Greenfoot program? Or am I just loosing my time maybe... Any help will be appreciated

adding an object from the code

Replied to by RcCookie, about 5 years ago:

What you do add the object itself to the world it is already in, so you do nothing. You first need to create a new instance of Missile and then add that instance to the world: <Code Omitted>Or shorter: <Code Omitted>
