Leaderboard

i meant when people play the game, they can enter their name, and when they finish playing, their score will be saved in leaderbourd (which is on menu screen) so that when they click on it, they can see other peoples' scores who played the game

If this is for on the site, then select 'Edit>Import class...' from the menu bar and select the 'ScoreBoard' class and click on the 'Import' button. Then for the action when the leaderboard button on your menu is pressed, create a new ScoreBoard object; but, only if storage is available (refer to the UserInfo class API documentation on this).

danpost can you write the code?? i don't understant what do you want to mean by "Then for the action when the leaderboard button on your menu is pressed, create a new ScoreBoard object; but, only if storage is available (refer to the UserInfo class API documentation on this)."

I have done the first thing (If this is for on the site, then select 'Edit>Import class...' from the menu bar and select the 'ScoreBoard' class and click on the 'Import' button.) but i don't understand what to do next This is my function for increasing the score and i already have a the counter for keeping the score when my snake eat something public void Eat() { Actor fln; Actor hambur; Actor chip; Actor pzz; Actor apl; fln = getOneIntersectingObject(flan.class); hambur = getOneIntersectingObject(hamburger.class); chip = getOneIntersectingObject(chips.class); pzz = getOneIntersectingObject(pizza.class); apl = getOneIntersectingObject(apple.class); if(fln != null) { World world = getWorld(); Greenfoot.playSound("slurp.wav"); world.removeObject(fln); SpawnNewFlan(); Eaten(1); Score++; if(Score % 3 == 0) {SpawnNewHamburger();} if(Score % 10 == 0) {SpawnNewPizza();} if(Score % 6 == 0) {SpawnNewChips();} } else { if(hambur != null) { World world = getWorld(); Greenfoot.playSound("slurp.wav"); world.removeObject(hambur); Eaten(3); Score += 3; Countt++; if(Countt % 4 == 0) {SpawnNewApple();} if(Score % 10 == 0) {SpawnNewPizza();} if(Score % 6 == 0) {SpawnNewChips();} } else { if(chip != null) { World world = getWorld(); Greenfoot.playSound("slurp.wav"); world.removeObject(chip); timerStarted = true; moveAmount += 2; } else { if(pzz != null) { World world = getWorld(); Greenfoot.playSound("slurp.wav"); world.removeObject(pzz); Eaten(2); Score += 2; timerrStarted = true; moveAmount = 0; if(Score % 10 == 0) {SpawnNewPizza();} if(Score % 6 == 0) {SpawnNewChips();} } else { if(apl != null) { World world = getWorld(); Greenfoot.playSound("slurp.wav"); world.removeObject(apl); Eaten(5); Score += 5; if(Score % 10 == 0) {SpawnNewPizza();} if(Score % 6 == 0) {SpawnNewChips();} } } } } } public void Eaten(int amount) { sandstone sand = (sandstone) getWorld(); Counter theCounter = sand.getCounter(); theCounter.bumpScore(amount); }

First you need to use code tags around your code to display them properly in your discussion (see the 'Posting code?' link below the 'Post a reply' box). Next, how the score works is irrelevant to how the score is used at the end of a game. In other words, the methods given above are not what is needed in helping to get a high scores board working. Only how the 'Score' field is declared, where it is located and where you need it when the game ends.

here is my game ( http://www.greenfoot.org/scenarios/11556 ), if you can take a look and see it and tell me what to add to save the scores in my Leaderboard screen

First things first -- your subclasses of Menus are not menus and should not subclass Menus. They should each extend World. Your Menus class should look like this: and your other worlds that were subclasses of Menus should be similar to this: Then you can create a LeaderBoard class to create the image showing the top five players with their scores and have the LeaderBoardScreen constructor create and add a LeaderBoard object into the world.

if i change the Menus class and the subclasses of Menus nothing appear just my MenuScreen and the BackButton (no PlayButton, HelpButton, ScoreButton) please, if you can do what you said for me it will be great; i don't understand what to do...:(((

If you had change it to the way I said to change it, you certainly would be getting those buttons (lines 8 through 11 in my last post above adds those buttons to the world).

i will try again and i will edit this post with my response : ok i've done it; now how do I save the scores at the end of a game (when i die) in the LeaderboardScreen (my top 5 scores and the names if i can)??

Actually, the scores will not be saved IN the LeaderboardScreen class. They are saved in a file located either on your system (when running greenfoot there) or on the server (when running the scenario on the site). There are two places in your project where the game can end (1) in the Lemur class and (2) in the Bomb class. In both these classes, just before setting a new MenuScreen world active, you will need to call a (new) method in your Sandstone class to deal with saving the score for that user if it is a new high score for that user if that user is logged on. The method would look like this (for the Sandstone class): The line to use to call this method would look like this:
