GreenfootSound not acknowledging getVolume/setVolume?

By Bennylit, with no replies.

I have a music track I want to fade out, and I thought I could accomplish this by using this code: <Code Omitted>As you can see, it should slowly decrease the volume in intervals of 10. Well guess what? It doesn't. When I check the volume before and after it runs this code, it's the same. What's the problem here?

How do i export my scenario as a jar file

I can't open the jar file because of this error: Error: Could not find or load main class greenfoot.export.GreenfootScenarioApplication Caused by: java.lang.ClassNotFoundException: greenfoot.export.GreenfootScenarioApplication

Maybe that was the problem that caused them to remove it as a possible output option. Try going back a bit more.

Can someone please give me an idea for my final project? I need to make a new scenario, use 5 languages we haven't discussed in class, and have 2 different worlds W some actors. I need a user interface as it's supposed to be a game. Please give me an idea, I'm stuck.

If you were more clear as to what is needed, maybe someone might be able to help. As is, "5 languages we haven't discussed in class" is not only vague (not giving what languages you have discussed) but also ambiguous as to the type of language being referred to (spoken or programming). Of course, one c

I need to access a variable from another class. this works for one of them, but for some reason the second variable is not changing. << Code Omitted >> That is the second variable with does not work, << Code Omitted >> in this example the method does work. did I make a syntax mistake or something ?

Very confusing as far as which one worked and which one didn't. I hope you are not expecting the collision variable to update when all you did was move this actor. You performed no collision checking between the setting of the actors location and the testing of the co

I have found the problem, and for documentation purposes, I will share what I did to fix it. The problem was that when creating the rooms, even though they were final, some rooms were created before others. For example, this was the code for creating the final static rooms: <Code Omitted>You might notic

Checking the Solution for a Picross Game

I'm struggling to visualise how two 2D arrays in a 3D array would work for it?

Each 2D array in the 3D array is a solution with increasing difficulties. I only combined what you already had to simplify things.

just to double check, the indexes on the solutions array are row, column, solution right? I didn't think it would make that much of a difference since the clues essentially mean the same thing as the solution but I suppose the way it's stored and used does make the difference. How would an array representing my clues look so it doesn't turn out look

Greenfoot.ask() window doesn't close on web

Changing the act() code to call getKey() once and then use that key to decide what to do fixed the issue, though (I think using isKeyPressed() in act() was resulting in multiple text boxes opening on top of each other in web, whereas in Greenfoot the textbox opening pauses the program.

Still each string comparison should be accompanied with a check to ensure that the string returned is for the question asked. That is

Im trying to get the nextWave function to run in the Myworld class. However it doesn't seem to like it :( << Codes Omitted >>

In your Wave_management class, remove line 28. Maybe you can see why.

What does your code do? I have multiple different actors in my world. Sorry, I don't really know what I'm doing but getting started with stuff like this is super difficult because every slow tutorial is a mess to understand

Maybe you could show your "array as subclass of World" stuff so we could better understand where you are coming from.

my program stops after an actor reaches the edge

hi! im coding a game where the player has to dodge falling asteroids. i changed my code to have a 1/100 chance to spawn a new asteroid, but now my program stops after the asteroid reaches the edge of the world. << Code Omitted >>

If an error message shows, copy and paste here. If not, try commenting out lines 15 thru 19 in Asteroid class code above. Or try commenting out lines 11 thru 14 in the GameWorld code above. Hopefully that will give indication as to which code triggered the game over. Then, go from there.

i dont know how many pixels the png sould be so that it fits perfectily withouts dubbeling..im on my firsth project i have 3 weeks left of a 3 month program...

Your would dimensions are defined in the "super" statement. After which, you can, after maybe first filling the background with an opaque color, draw the image on the background. Scaling the image is also a possibility. But, unless you resize the actual ping, you won't be able to use the default class image feature.
