You can use the methods getIntersectingObjects or getOneIntersectingObject from the greenfoot API to detect whether your actor touches another actor. The method getIntersectingObjects will return a list of objects and getOneIntersectingObject will only return one object. You can use this methods e.g. like this:

To add the variable you can use this code: <Code Omitted> To make your actor loose a live when it hits another actor is easy. Try it like this: <Code Omitted> The only problem is that after you lost a live the actor will still be there and your actor will get hurt again. Do you want to remove the other actor after it has hit you

The easyest way to add a spawn point would be to add new objects to the world when a condition is fullfiled: <Code Omitted> This will make new objects spawn when there are less than it should be.

We really do not have enough information to help at this point. Best might be to post the code for the whole class.

If any basic key can unlock any basic door, then all you need to do is: <Code Omitted>With this, you do not need to keep track of ANY amounts. If there is a special key and door, you can use separate classes for those classes and work them separately.

It appears you imported the Scoreboard class and then edited it, ruining the basic structure of the class. (1) the field 'scoreCounter' field is not declared or initialized anywhere (not sure if that method belong in this class) (2) only the first statement (the 'return...') is reachable in the 'getScoreCounter' method (see note parenthesized in (1)) (3) the last block (starting '{ if(UserInfo.isStorageAvailable())...' is not within a method (4) the 'SCORE' field is being set to 'newScore', yet 'newScore' seems to come from nowhere (I think you delected a constructor declaration for the bl

NumberFormatException is an unchecked exception, so you don't *need* to surround it with the try catch block (though you may wish to if you're parsing something that may not be a valid integer, user input for e

:O thank you i try use in my game thanks again

Again, in order to assist in removing the text, you need to show how it is displayed. "Show your code!".

ok ill try these solutions, thanks!

With the code given, once line 25 executes you will lose the reference to the GreenfootSound object (in fact, you will lose any connection to the 'musica' world that will no longer be active). You could avoid the lose by passing this world on to the next, but I really do not see any real benefit by having a separate class for music control. Better might be to put the GreenfootSound field declaration statement and the two methods in one of your other world classes. It would help to know your world class structure before offering any advice as to where it might be best to move them.

Awesome. Although I prefer making pokemon fight until they faint, much more humane. Also, this topic should be under other, not programming.
