Runescape Applet

I managed to run the Runescape applet in a JFrame so far.
Now I would like to get the player's coordinates from the applet as I don't want to analyse the pixels of the game yet.
Is that possible? I've seen a bot from rsbots.net that actually could display the character's absoulte coordinates.

Here is my code:

Code:

Class loader = Class.forName("loader");

Client client = new Client(); // Client extends JFrame
RSStub stub = new RSStub(44, true, 15); /* world numer, is members world, country
  RSStub implements AppletStub */
			
Applet app = (Applet)loader.newInstance();
			
app.setStub(stub);
app.init();
app.start();

client.AddApplet(app);
client.setSize(600, 400);
client.setVisible(true);

Thanks
Great site btw

===========================================

I have been searching for tutorials and analysed some java bot codes now and I want to share my results:
You can do that by either reflection or BCEL (which basically also is reflection, but you can also inject code).

I tried to analyse the loader.class file (the file that is executed first). When I view it in a bytecode-viewer (or using java reflection) I get the following fields and methods:

Code:

h : String
i : String
j : int
<clinit>()
a : Applet
b : int
c : boolean
d : int
e : boolean
f : boolean
g : boolean
k : int
loader()
a(boolean, ml, c, byte)
a(byte, c, boolean)
a(byte[], File, byte)
a(c, byte[], int, boolean)
a(int, File)
a(int, String)
destroy()
init()
paint(Graphics)
run()
start()
stop()
update(Graphics)

And I found out that loader extends Applet.

Has anyone an idea how to proceed?

 

You need to find a certain variable or 2 and maybe do a calculation and then you will have the coordinates. I'd decompile Rsbot and look in there for which variable it is.

 

Thanks for your reply.
I found out that to get the coordinates and other game-related stuff I need to get an instance of "client" (from runescape.jar). But I don't want to use an unsigned applet because it is incredibly slow.
How can I get the instance of client when using the class loader (from loaderXXX.jar)? I tried to analyse the bytecode but I didn't have any success.

 

Get the classloader from the loader that is responsible for loading the client classes.

 

Explain. I think I know what you are talking about, but still explain Sir Jimmy.

 

Ollie already did (the op posted this question @MITB, too).

 

the loader uses a custom classloader to load the client classes; hijack it
