Yes, that's true: I was mainly using the Fib series as an example, and I wasn't sure if making a note about there being better ways to calculate the Fibonacci series--especially if you're generating the whole series up to a certain number or are using it sparingly--would confuse the issue. In fact, if you recall, I had made a post earlier in the thread self-warning that trying to use dynamic programming for simple issues can lead to inefficient solutions.

How do I add new libraries to java so my program will compile?  I cannot find anything to help me with this.

I'll assume you're using Eclipse. In that case, right-click on your project folder in the package explorer, look under Build Path, and click either Add External Archive or Add Library (depending on what you're using).

As an aside, did anybody else notice this announcement a couple of months ago? JetBrains. Doing C++ IDE.

Awww yeah. Now, JetBrains for those who don't know did IntelliJ and Resharper. IntelliJ is by far the best Java IDE simply due to it's incredible refactoring support, able to automate a lot of nifty things like bringing functions out into other classes, and Resharper brings that refactoring support to C# as a Visual Studio plugin (but ain't free sadly). And they're bringing their refactoring voodoo to C++? The lack of such tools is the biggest problem with C++ development atm for me, so...awww yeeeaaah

I'm not using Eclipse.  I'm using a compiler by the name of Jgrasp, because I have dial-up, and it takes me nearly an hour to download a 10mb file like Dwarf Fortress.

I took a quick look at jgrasp.  Looks like to add external libraries, you need to follow Settings->PATH/CLASSPATH and select the Classpaths tab.  From there, press the New button and browse to the library.

In Java, to add things like libraries, you need to place them into the classpath.  IDEs, thankfully, pretty much always have some means to do this partially for you once you tell it what libraries you want.  If you're ever using an unfamiliar IDE, just look for something labelled classpath.

And to think my connection was slow... Do you have that connection speed because you don't need any faster, or because you don't have anything better available where you live?

Nothing better, apparently.  What is worse is my neighbor has wi-fi...

Managed to get Eclipse via download from the library, though.

This error is confusing me terribly, in C++.

Code: [Select]

//// Header
#include <map>
typedef std::pair<int,int> coord;

class node
{/* stuff */
};

/* ... */

//////// Cpp file.
vector<coord> Pather::path(const coord& starting, const coord& destination, const double waveResistance)
  {
  map<coord, node> closedset;
  map<coord, node> openset;

  coord start = starting;
  coord dest = destination;
  openset[start] = node(start, 0, heuristic(start, dest), true);

  /* LOGIC */
  }

What in the world would prevent map<coord, node> from being legal? ._. Been on this for like 20 minutes. Making it more perplexing is the fact that it worked just fine in a different file with near identical everything, including context and class construction.


Edit: NVM, apparently it's a naming conflict >_>

I've been trying to use this tutorial in order to get the basics of how to program a rougelike game, but for some reason, despite it apparently working for the person who wrote the tutorial, the following segment of code, specifically the bolded portion, isn't working.

Spoiler: Entire Code provided by the tutorial (click to show/hide)

import net.slashie.libjcsi.wswing.WSwingConsoleInterface;
import net.slashie.libjcsi.ConsoleSystemInterface;
import net.slashie.libjcsi.CSIColor;
import java.util.Properties;
 
public class HelloDungeon{
 
   public static void main(String[] args){
      Properties text = new Properties();
      text.setProperty("fontSize","20");
      text.setProperty("font", "Courier");
      ConsoleSystemInterface csi = null;
      try{
         csi = new WSwingConsoleInterface("Insert Game Name", text);
      }
      catch (ExceptionInInitializerError eiie) {
         System.out.println("*** Error: Swing Console Box cannot be initialized. Exiting...");
         eiie.printStackTrace();
         System.exit(-1);
      }
      csi.print(0,0, "Welcome to the Dungeons of Doom!", CSIColor.WHITE);
   }
}

Spoiler: Error (click to show/hide)

The constructor WSwingConsoleInterface(String, Property) is undefined.

What is going on?

You'll need to copy and paste the actual errors, or at least the details of the problem, to get any meaningful answers to that.

Edited to include the error.

Looked at the code found here.

Code: [Select]

public WSwingConsoleInterface(String windowName, Properties configuration)

This is the class you want.

Wait, where do I put that class?  In the WSwingConsoleInterface.java or somewhere else?

[Mego]

No, use it instead of the Property class. The tutorial is outdated.
