starting some java programming can anyone help me

[danielrhodea]

Hi all

I'm starting programming with java and have been converting wowmapviewer code to java (really havent converted any yet lol @ me but trying, can smeone help me out please)

lol @ me, java is soooo easy to use once I get over my dependency on pointers and addresses lol

import java.io.*;
import java.lang.String;
import java.lang.Integer;

public class DBCFile
{
	public DBCFile(String _filename)
	{
		File f = new File(_filename);
		if(f.canRead())
			filename = _filename;
		else
			error = true;
	}

	// Open database. It must be openened before it can be used.
	public void open()
	{
		try
		{
			FileReader f = new FileReader(filename);
			char[] hdr = new char[4];
			
			char[] na = new char[4];
			char[] nb = new char[4];
			char[] es = new char[4];
			char[] ss = new char[4];

			f.read(hdr); // Number of records
			
			assert(String.copyValueOf(hdr) == "WDBC");
			header = String.copyValueOf(hdr);
			f.read(na); // Number of record
			recordCount = (na[0]) | (na[1]) | (na[2]) | (na[3]);
			f.read(nb); // Number of fields
			fieldCount = (nb[0]) | (nb[1]) | (nb[2]) | (nb[3]);
			f.read(es); // Size of a record
			recordSize = (es[0]) | (es[1]) | (es[2]) | (es[3]);
			f.read(ss); // String size
			stringSize = (ss[0]) | (ss[1]) | (ss[2]) | (ss[3]);
			       
			assert(fieldCount *4 == recordSize);
			
			
			data = new char[recordSize * recordCount + stringSize];
			
			stringTable = new char[(data.length) + recordSize * recordCount];
       		
			f.read(data);
       		/*
			String tmp = "";
			for(int i=1*recordSize+stringSize;i<stringSize;i++)
				tmp += String.valueOf(data[i]);
			System.out.println(tmp);
			*/
			f.close();
		}
		catch(IOException exc)
		{
			System.out.println("IOException"+exc.getMessage());
		}
		trace();// uncomment to hide debug info
	}
	private Boolean error = false;
	public Boolean hasError(){
		return error;
	}
	public void trace()
	{
		System.out.println("Traced output... header:"+header+" record count:"+recordCount+" field count:"+fieldCount+" record size:"+recordSize+" string size:"+stringSize+" error:"+hasError());
	}
	private String header;
	private String filename;
	private int recordSize;
	private int recordCount;
	private int fieldCount;
	private int stringSize;
    private char[] data;
    private char stringTable[];
}

anyone with noggit, wowmapview, dbc loading etc should understand this code it's my attempt at re-writing from c++ to java the loading of a dbc file,
I do not wish to simply be spoon-fed so if anyone can help me work through the code, I understand the C++ but cannot convert it to java as I'm a java n00b and know nothing about it's namespaces etc, I am quite well versed in C# and flex though which im aware are java-esque syntax

thanks so much, hopefully soon I'll have something to share back with

btw I think the data segment is wrong as well as the string table but other info correllates to wowdev records

Wow.. Lol @ getting more posts..

[danielrhodea]

thank you, if you can delete please do, I concatenated the posts into one, do you know java at all???

[Krillere]

Sorry no, I know C#. I just felt like telling you that triple-posting is not OK at all. :-)
( If I'm not completely wrong, it's actually against the rules! Correct me if I'm wrong. )

wdt class, traces output of .wdt ATM (it will allow toggling of them by using
(eightbytes | 1) & automatically generating a blank .adt file if one does not exist in the future)

A problem exists for me creating a wdt file atm, i'm sure ill crack it soon!!!

import java.io.*;
import java.lang.String;
public class WDT
{
	private boolean[] fileperms = {false,false};
	private String filename = "";
	private boolean debug = true;
	
	private boolean[] data = new boolean[4096];//because there are 64*64 possibilities 
	
	public WDT(String _filename, boolean autoOpen)
	{
		filename = _filename;
		File fil = new File(_filename);
		if(fil.canRead())//check read capability
			fileperms[0] = true;
		
		if(fil.canWrite())//check write capability
			fileperms[1] = true;

		if(autoOpen)
			read();
	}
	private char[] flip(char[] target)
	{
		char[] tmp = new char[target.length];
		for(int i=0;i<target.length;i++)
		{
			tmp[(tmp.length-i)-1] = target[i];	
		}
		return tmp;
	}
	
	private void trace()
	{
		for(int row = 1; row<=64 ;row++)
		{
			for(int col = 1;col<=64;col++)
			{
				System.out.print( ((data[((row-1)*64)+(col-1)]) ? ("x") : ("0")) + ((col == 64)?("\n"):("")) );// = ( ( (fourcc[0]|fourcc[1]|fourcc[2]|fourcc[3]) & 1 ) == 1) ? (true) : (false);
			}
		}
	}
	
	public boolean read()
	{
		if(!fileperms[0])
			return false;
		
		try
		{
			FileReader f = new FileReader(filename);
			char[] fourcc = new char[4];

			boolean eof = false;			
			while (!eof)
			{
				int tmp = f.read(fourcc);
				if(tmp == -1)
					eof = true;
				fourcc = flip(fourcc);

				if((fourcc[0] == 'M') && (fourcc[1] == 'A') && (fourcc[2] == 'I') && (fourcc[3] == 'N'))
				{
					f.read(fourcc);
					f.read(fourcc);
					for(int row = 1; row<=64 ;row++)
					{
						for(int col = 1;col<=64;col++)
						{
							f.read(fourcc);
							f.read(fourcc);

							data[((row-1)*64)+(col-1)] = ( ( (fourcc[0]|fourcc[1]|fourcc[2]|fourcc[3]) & 1 ) == 1) ? (true) : (false);
						}
					}
				}
			}
			if(debug)
				trace();
		}
		catch(IOException ioexc)
		{

		}
		return true;
	}
	
	public void debugMode()
	{
		debug = !debug;
	}
	
	public void setActive(int row, int col)
	{
		(data[((row-1)*64)+(col-1)]) = true;
	}
	
	public void setInactive(int row, int col)
	{
		(data[((row-1)*64)+(col-1)]) = false;
	}
}

lol for anyone reading this don't bother going down the java route, I never did get .wmo files working at all lol
