<< Quote Omitted >> It doesn’t work though
Change lines 32-33 to: <Code Omitted>The Preparation object removes itself when clicked on. The world only needs to see that is has been removed.
Thank you very much

I made a code that if i touch a certain block all lava in my level gets removed. that works and all but then if i stop touching that block i want my lava to come back in the level so you cant get passed << Code Omitted >>
Add a method in your world class that adds all Lava objects into your world. Move all code pertaining to Lava objects in your prepare method into this new method while maintaining their order. Call the method from the prepare method and from the above to add lava back into the world.

What should I do to make LittleRedCapGun notice when a bullet kills something?
Tell the LittleRedCapGun object directly instead of letting it try to figure it out by itself. Add a method to LittleRedCapGun that the bullet can call to "tell" it something was killed and have the bullet call that method when it kills something.

I tried accessing a class from the world class and create a condition where the game only starts working once I click on that specific class. When I do that though an error appears which doesnt let me start the game anymore! << Code Omitted >> << Error Trace Omitted
Apparently, there are times when there is no Preparation actor in the world. Therefore, you must check that there is one before trying to access one from the world: <Code Omitted>

Rotating gifs

I'm trying to rotate a character gif 180 and mirror it when moving to opposite side, but i dont know how to do it with gifs
Best would probably be to create 2 GifImage objects and immediately rotate and flip all the images of only one of them for left moving. You will probably then need a GifImage field for the current image set. That is, you will have 3 GifImage fields; one for left images, one for right and one to be set to one of those two for the current set to use for the actor.

I need help with Objects spawning on each other

Hey, I was trying to prevent Objects (no specific ones) from spawning on eachother. << Code Omitted >> The code itself seems to be okay but I dont know how to implement the addObject command, since I dont want to add a specific class.
Correct me if I am mistaken, but I would presume that the actor to be added would be r, from the parameter of the method. I am not sure how the method will eliminate overlapping. It will probably make it such that less than half any object already in the world will be overlapped by that which is added; but it will not completel

The game I created on greenfoot won't reset when I press the "reset" button but forces me to restart my page. Pls help.
I believe it has something to do with the usage of GreenfootSound objects.
