OHHHH thank you, for the fast reply and the help!

Will reply on your discussion thread, here.

Ah, I see my error. I corrected it, and it works perfectly. Thanks!

Do you mean this? <Code Omitted>

With the code suggested by valdes, your hero must remain in the world. If at some later time (or even now), you decide that the hero should be removed from the world for some reason, the code here will fail. A simple adjustment will assure that no changes elsewhere in your code will cause any problems. Change the act method given to: <Code Omitted>The 'move' method should probably be made a 'private' method so that it cannot be called from outside the class.

The only thing that immediately catches my attention is that you are having the health lost when NOT touching a Samus object (line 28 of the Lavnar class). I do not currently see any reason for having the 'touchingSamus' field in the Lavnar class. Its value is being altered within the class; but, other than that, it does not appear to be used anywhere which warrents its existence in your code. Lines 36 and 37 of the Lavnar class can be simplified. Line 36 is not needed as a reference to the LavaLand world is already available in the 'lavaLand' variable (line 26). Just change 'w' in li

This is a Java crash. As it says in the portion of the log you posted: You have the option of reporting a Java bug. You could also try a different version of Java (including OpenJDK) to see if that helps.

<Code Omitted>

In a literal sense, a object can be a class -- that is a Class object is truly an object -- an object of type Class. But an object of type Class is never an object of type World. So, it is like comparing apples to bananas.

The 'getHitAEnemy' method can be reduced to this: <Code Omitted>To explain the reduction, the last two lines ends up calling the current method with a false value, which only sets the value of A1 to false. So the only other change within the method is incrementing B1 if the boolean parameter was true. It is difficult to understand what you are wanting the method to do (or even what conditions are required before calling the method from outside the method). This is due to the non-descriptive names of you

You could also create a separate class (one that isn't a subclass of Actor or World), and store the numbers there. This class could, for example, be called PlayerData, and each time a new world is created, it asks that class for numbers you want to pass through.

You should refrain from reviving old discussion thread and create a new one for your issue. Include the code around which the error occurred and copy/paste the complete error message to allow us to determine where the problem resides.

The World class API does not contain a 'getWorld' method as does the Actor class API. However, if you are trying to code this in the Space class, you only need to use the 'this' keyword. That is: <Code Omitted>The thing about it is that you do not need this line at all in this class:

Sure: <Code Omitted>
