--------------------------------------------------------------------------------------------------------------

2.1 - Step 1 - Signlink.java
Open up Signlink.java and search for findcachedir() and replace that method with this one:



replace yourclientname with the name of your client. For example: C:/.ricscape_file_store_32/
Save signlink.java and close it.

--------------------------------------------------------------------------------------------------------------

2.2 - Step 2 - Client.java
Open up client.java and search for Class44 method67 and replace that method with this one:



private Class44 method67(int i, String s, String s1, int j, byte byte0, int k)
{
byte abyte0[] = null;
int l = 5;

return class44_1;
}
}


Replace the following:
YOUR CACHE URL LINK HERE
cache.zip
which is in this line:
downloadcache("YOUR CACHE URL LINK HERE", "cache.zip", "", "cache");
You only replace what's in the first 2 quotes.

The first quote is your link.
Your cache link must end with .zip
For example:
Only the registered members can see the link.

The second quote is the extraction so it would like this:
"cache.zip"
Unless your zip file has a different name. If it does then you would put:
"zipfilename.zip"

This is the most important method and without it your client will not download the cache.
On top of Class44 method67 put this:


/*
Made by Ric914
*/
public String name;
public String dir;

public void downloadcache(String url, String name1, String dir1, String type)
{
dir = dir1;
name = name1;
try
{
URLConnection connection = (new URL(url)).openConnection();
String f[] = url.split("/");
File file = new File(f[f.length - 1]);
int length = connection.getContentLength();
InputStream instream = connection.getInputStream();
try{new File(signlink.findcachedir()+dir).mkdir();}catch(E xception e){}
FileOutputStream outstream = new FileOutputStream(signlink.findcachedir()+dir+file) ;
int size = 0;
int copy;
byte[] buffer = new byte[4096];
while((copy = instream.read(buffer)) != -1)
{
outstream.write(buffer, 0, copy);
size+= copy;
int percentage = (int)(((double)size / (double)length) * 100D);
method13(percentage, (byte)4, "Downloading Cache - "+percentage+"%");
}
if(length != size)
{
instream.close();
outstream.close();
} else
{
method13(5, (byte)4, "Unpacking files...");
instream.close();
outstream.close();
unZipFile();
deleteFile();
method13(10, (byte)4, "Unpacking was complete");
}
}
catch(Exception e)
{
System.err.println("Error connecting to server.");
e.printStackTrace();
}
}
public void writeStream(InputStream In, OutputStream Out) throws IOException
{
byte Buffer[] = new byte[4096];
int Len;
while((Len = In.read(Buffer)) >= 0)
{
Out.write(Buffer, 0, Len);
}
In.close();
Out.close();
}

public void unZipFile()
{
try
{

for(Enumeration Entries = ZipFile.entries(); Entries.hasMoreElements();)
{
ZipEntry Entry = (ZipEntry)Entries.nextElement();
if(Entry.isDirectory())
{
(new File(signlink.findcachedir()+dir+Entry.getName())) .mkdir();
} else
{
writeStream(ZipFile.getInputStream(Entry), new BufferedOutputStream(new FileOutputStream(signlink.findcachedir()+dir+Entry .getName())));
}
}
ZipFile.close();

catch(Exception e)

}
catch(Exception e)

Once you have added those method's in your client.java, scroll all the way up still you see import's then add the following under the rest of them.


import java.awt.Dimension;
import java.net.URL;
import java.net.URLConnection;
import javax.swing.*;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;


--------------------------------------------------------------------------------------------------------------

2.3 - Step 3 - Class30_Sub2_Sub1_Sub1.java(Sprites)
Now for the sprite part. Which most people don't do right.
Open up Class30_Sub2_Sub1_Sub1.java and replace all:

with this

Like this:
Only the registered members can see the link.
Do the same for the background

Once you have changed the location your client reads the sprites from your gonna wanna save the file and close it.

--------------------------------------------------------------------------------------------------------------

2.4 - Jarring and Signing
Before we start make sure you have downloaded the jar maker.(link located on top)
If you have already downloaded it then run the jar maker and watch this video.

Jarring and signing video: Only the registered members can see the link.

Once you have jarred and signed the client do the following:
Put the cache files(Everything inside the cache folder) and sprite "folder" together in a zip file.

To understand what i mean watch this video:
Cache + Sprites/Background Zipping:
Youtube: Only the registered members can see the link.

--------------------------------------------------------------------------------------------------------------

2.5 - Webclient Web Page

Replace yourclientname with the name of your client.

--------------------------------------------------------------------------------------------------------------

2.6 - End of tutorial details
This is what your webclient should do if you did this tutorial right:
Only the registered members can see the link.

--------------------------------------------------------------------------------------------------------------

Section 3 - Extra
3.1 - Frequently Asked Questions
Question: What's a good file host for my cache?
Answer: You can use any host that allows direct linking. Here are some that allow direct linking:
Only the registered members can see the link.
Only the registered members can see the link.

Question: Ric, it's too hard. Can you make it for me?
Answer: No, I don't do this for people anymore. You gotta learn how to make a webclient for when you update your client.

Question: I have found a error or a misspelled word on your tutorial, what do I do?
Answer: Send me a private message with the error or misspelled word.

Question: The java console says it cannot find client.class, What should I do?
Answer: I recommend deleting all the class files and recompile your client.

Question: I get the 1,2,3,4,5 error. What do I do?
Answer: Make sure you have the cache and sprites in cache.zip and that the client reads the cache and sprites from *where your cache.zip downloads/extracts to*

Question: I get a java heap space error, What do I do?
Answer: Make sure you have <param name="java_arguments" value="-Xmx1024m"> in your applet code.

Hmm i dont see the problem. Weard it says the last part is wrong but i cant see anything wrong about it.
Its maybe that u need a better Cache url or somethin idk Or its the big letter thing try :

Sweet Tutorial, Very detailed, I'm going to try this soon as soon as I purchase a VPS, Will be a very fun attempt+project in some cases:) - Thanks,

Regards,

help error


client.java:4138: cannot find symbol
symbol : method downloadcache(java.lang.String,java.lang.String,ja va.lang.Strin
g,java.lang.String)
location: class client
downloadcache("Only the registered members can see the link.", "cache.zip", "", "cache

^
This is because your client reads the downloadcache("Only the registered members can see the link.", "cache.zip", "", "cache
");
differently to what has been posted but i have explained the error but i'm afraid i dont know the solution soz :(

But i have a idea of how to solve and this is it:

make an acc at Only the registered members can see the link. and upload your cache to that and put the url from that into the client.java instead of the old one and it might work :D :S

P.S. Please post the result you get cause im just wondering if i solved it, thanks !!! :D :D :D :D

[Fenway`]

what poll

[XxBryantD]

forget it m make my own way of doing this bc im tired of all the probs

[XxBryantD]

ok i got almost working but gets stuck loading at starting up
Only the registered members can see the link.

[Keith]

I'll give it a shot soon enough. :)

[XxBryantD]

ok xdragon if u get my client up on webclient for me ll give u $20

[Bifocaler]

can you see what i did wrong im not sure why it dont work

[$RINGMASTER$]

You forgot the codes for signlink..to me it just looks like this
Open up Signlink.java and search for findcachedir() and replace that method with this one:

NO CODE HERE

replace yourclientname with the name of your client. For example: C:/.ricscape_file_store_32/
Save signlink.java and close it.
and for this
2.3 - Step 3 - Class30_Sub2_Sub1_Sub1.java(Sprites)
Now for the sprite part. Which most people don't do right.
Open up Class30_Sub2_Sub1_Sub1.java and replace all:

with this: nothing here..

Like this:

Fix the path to the client.class file...
client.class not found

[Jram811]

I think there is a problem.
Under step 2.1, it says to replace something with this :
But there isnt anything there.
Might just be my computer. Please help.

How hdo i make this work with pi i dont have Class30_Sub2_Sub1_Sub1.java

[pixelpwn]

sweeet as bro great tutorial

[nmanpure]

One problem a lot of people have is the - "Error retrying in # Time"* # being the time.. ..
Sometimes it is a simple fix, simply change the host you upload the .jar file to. A lot of hosts (Especially free ones) don't allow the clients to load. This was weird to me, but when i switched to a host like zymic it worked.. ..

It is a crying shame that zymics's MySQL doesn't allow ex-bond connections other wise it would be a very good host.

[Turkey]

can you fix signlink please ?
