Start Screen

By Camyh15, with 5 replies.
Last reply by danpost, about 11 years ago:
I have multiple scenarios that uses buttons to actually display the codes of classes within that scenario. Most, if not all, show the code for the subclass of World that shows the buttons being created, referenced in fields, and checked for clicks in the act method. You do not even have to download the scenario to check it out (though for some you may need to be logged in and/or play the game out to get to the screen with the buttons). Just run the scenario here on the site. Most of them are tagged 'source-text'.

Staying Still

By Camyh15, with 1 reply.
Replied to by danpost, about 11 years ago:
The only place you can use 'Greenfoot.start();' with any effectiveness is in code that executes during the resetting of the project (in your initial world constructor or in any code that executes during the running of that constructor. No code outside of that can execute unless the project has been started. You can use the click on the 'Run' button as the signal to proceed to game mode. Make use of the 'started' method for that.

Messing around with multiple worlds....

By WG95, with 1 reply.
Replied to by Super_Hippo, about 11 years ago:
Your 'world' variable holds a 'World' object. The 'World' class does not have a 'getLevel' method. There are some ways to work with this. For example you could arrange your classes like this: -World ---Levels -----Level1 -----Level2 Then you can put the 'getLevel' method into the 'Levels' class and replace lines 6 and 7 with this line: <Code Omitted> Another way is to have all levels in one class. It depends on the differences between the levels if this could be a good idea. If (almost) only the creation of the world is different,

the transparency of another object

By Milla, with 3 replies.
Last reply by danpost, about 11 years ago:
First, you are using 'getWorld' like it is a variable, not a method (there are no round brackets after it). Second, 'getWorld' is an Actor class method (not a World class method), meaning you need an actor to execute the method on. If the given act method is in the Level class, which is a subclass of World, it is already executing on a world object and you do not need to 'get' the world: <Code Omitted>should work.

how to get an explosion to appear when an actor disappears

By willy123, with 4 replies.
Last reply by danpost, about 11 years ago:
I guess I was mistaken. I know that the book scenarios use an Explosion class in at least on of its versions of Asteroids. Have the world act method show the game over screen when no Explosion object and no main actor object is in the world.

I want my wombat to surround rocks when he calculates the distance in this method. How can I do that?

By Blackskater, with 1 reply.
Replied to by danpost, about 11 years ago:
Are you using a gridded world? (what is the cellsize of your world) My intuition says it might be '1'; but, I would like verification on that to be sure. How can one object (a wombat) surround multiple objects (rocks)? I would presume that your wombat is using the given method to find the closest Rock object to itself. Please explain how the information (what rock is closest) will be used in how the wombat should behave.

Hello, can you get bigger actors (enlarge them). If you can how?
Just give the actors bigger images (or scale them up in size).
I gave you the method name explicitly.

What's the 'scale' method?
and we discussed it specifically.

Make a New Level

By Camyh15, with 3 replies.
Last reply by danpost, about 11 years ago:
No one can tell how you tried it. You need to show what code did not work. You also need to be more detailed in your explanations -- how are you making another world? If you remove all actors or set a new different world active, then the old actors cannot still be in the world unless you keep references to them and add them in specifically.

Promote Code Snippet to Method

By JaSSoftware, with no replies.
Is there a command that can automatically PROMOTE a section of code into a Method (within the same class). You would select a section of code - Activate the Promote Method which will ask you for a method name. Then the code would be replaced with the method_name() ...and insert a section of code (at the end) with... public void Method_Name() { // Highlighted code inserted here! } -- Alternate. The code could (instead) by re-inserted into the clipboard and let the Coder insert it where they want. BTW does the editor have an UNDO feature?

hi there danpost are you able to see the code of every game made if you are could you send me the code on my scenario for i cant openeditor and i need the code of my copied one so i can see the errors
It is only possible to see the code of those scenarios that have their source published (there is an option checkbox for this when sharing a scenario on the site -- its caption reads 'Publish source code'). Any scenario can be re-shared changing whether this is done or not (of course, any changes to its code will be updated also).

Can't open editor of actor or documentation

By g-bostaurus, with no replies.
Hello. I'm working with arch linux and installed greenfoot. Not everything is fine: -right-klick on actor gives "open documentation", but nothing happens. -double-klick on actor: nothing happens -double-klick on a subclass like leaf opens the editor, but if I change to documentation, there is a error-hint saying I should have a look at the logfile.txt. This is it: <Code Omitted>As far as I see, all mentioned paths are correct and filled. Does anyone have an idea what I could do to make greenfoot run correctly?
