What are you working on? May 2012

[Geel]

I've been working on a Runescape private server in C# recently. Most others are in Java (I know of only one other that's in C#), and they are all horrible abominations under the hood. I decided to write a better one in C#, so now I am.

Runescape's packet protocol is very (and intentionally) convoluted. They use either little, "middle," or big endian, in addition to "Special A, B, C" datatypes (they're just simple arithmetic operations). The use of these is seemingly random--packet 105 may have three shorts, but each short could be a different endian order, etc. However, packets will always be consistent--packet 105 will always have three shorts with that exact order.

After finishing the login process, I wrote the player movement/chat code. Then I wrote the Item code--in such a way that it makes it easy to write a subclass of Item and, using reflection magic, automatically populate a list of "special" Item classes. In addition to that, I had to load Item information from the Runescape cache, which was annoying as hell. I eventually just modified the source of the client to, when it loads the items, write their information to a file, since I didn't want to have to work out reading from the cache myself.

My latest accomplishment is getting NPCs working. They can't move or attack yet, but they can spawn and whatnot. It's easy to write custom code per-NPC; just write a subclass of NPC and override the GetIDS() method, which returns an integer array of the IDs this NPC is written for.

Picture of NPCs:

The server and client are version 317, which is a very, very old version, but from my experience, its packet protocol is the most documented.

Neat function so I gave it a try:

I'm currently working on a graphics abstraction layer (GAL) for the Parrot Virtual Machine. The cool thing about this is that it allows other languages running on Parrot VM to use it.
This means I write my code once, and Java programmers, Javascript programmers, Python, Perl, or Haskell programmers, can start using my library.
I write it once, and people can use it in any language using the Parrot VM. This shit is amazing!

Ugh, I'm at the point in my language where I've got to make a line-by-line debugger of some sort or SOMETHING :( it's hard to figure out where my code fucks up.

What language are you writing it in?

[Jawalt]

[QUOTE=Perl;35926748]What language are you writing it in?[/QUOTE]

C# as sort of a proof-of-concept deal, but I want to rewrite it in C eventually. For portability/speed, and the language doesn't really gain much being written in C# over C.

if it's C# can't you go through the code evaluation step by step using breakpoints?

Yes, but all the code is in different places the way I've set things up, it's hard to follow.

[QUOTE=Jawalt;35927583]Yes, but all the code is in different places the way I've set things up, it's hard to follow.[/QUOTE]

Then add some sort of global function for a 'tick' system so you could break it, maybe :v:

You could probably get pretty far with just a "debugger;" statement which pauses execution and outputs a stack trace + some kind of variable dump perhaps with some form of assert so you can conditionally output it.

touched up the pissing mini-game, this is on hard mode, which is probably induced by drinking a lot, sleep deprivation, or a combination of both.

Fraps fucked up the mouse cursor or something. Also NPC->Player dialogue does work, I just didn't show it.

I've been using GWEN for a little while now, and it's pretty great. There's just a few small bugs here and there that i've found with docking.

(it has annotations describing what's happening if you don't understand)

So i'm working on figuring out why this happens. I added an issue to the bugtracker in the meantime.

The collision checks run on line 61 & 64, and 67 & 70 respectively, are completely identical. Sure you didn't forget to change the +/- operators somewhere in there?

I didn't look long enough to figure out the problem but for starters your 4 if statements are sets of identicals. Line 61 is identical to line 64. Same with Lines 67 and 70. So each one is overriding the last's value set to PlayerX and PlayerY

Heh, someone beat me to it.

Reverse engineering is really interesting for some reason.

On a side note, how would I force a program that is hardcoded to connect to a remote ip, instead connect to some other ip I've specified?
