[C# - Development] Jolt Environment

Hey

Over the last 2 weeks or so, I've been working on a project called "Jolt Environment", basically a framework for RuneScape, but "Jolt" is an environment, which is powered by MySQL and ION storage, and TCP asynchronous connections. Everything runescape is within the namespace "RuneScape", and everything in Jolt, is not requiring anything from that, so logically, you can basically delete the runescape namespace, and create a emulator of your own usage Jolt

Requirements to Edit / Run:
VS10 with .NET 4.0
MySQL database

Source is well commented for people willing to learn
Connection/NET for MySQL connection is in /Resources/ and also in /Bin/Drivers/ - You don't need to do anything, the emulator automatically loads the drivers for you

You can check out the source & the project @ http://ajravindiran.com/projects/jolt/

Feedback so i can improve :)

Now will this be using the same items and information as the original Runescape or will it be very custimized using the same playingfield?

I will be making it as original as runescape, the server will be really customizable, so it'll be up to the server owner for customization of NPCs, items, objects, and so forth

If you ever think about making it closed source I might be interested in helping out. :)

I've been monitoring this since before he made it public. This is gonna be the most lean framework ever created for RuneScape. Load speeds are incredulously fast, and the asynchronous socket protocol creates more efficiency with less need for looping code. Unlike anything ever released, I highly recommend people start learning this base for future development. If I ever manage, I'll even program for this as well

Asynchronous .NET sockets inherently use IOCP. This is the .NET framework we're talking about.

Havn't been doing much this week(end), But I've redone the byte vectors (streams).

Isn't really an "improvement", it is basically just more readable, and easier to work with.

From the older codec factory you would use the follow code to read / write streams to the runescape client:

Code:

---

character.GetCodecFactory().GetDecoder().ReadSignedByte();
character.GetCodecFactory().GetDecoder().ReadUnsignedDWord();

character.GetCodecFactory().GetEncoder().WriteByte(0);
character.GetCodecFactory().GetEncoder().WriteDWord(1);
character.GetCodecFactory().GetEncoder().WriteQWord(2);
character.GetCodecFactory().GetEncoder().WriteWord128(3);
character.GetCodecFactory().GetEncoder().WriteUnsignedByte(4);
character.GetCodecFactory().GetEncoder().WriteString("something");

---

Now:

Code:

---

character.GetCodecFactory().ReadByte();
character.GetCodecFactory().ReadInt32();

character.GetCodecFactory()
    .AppendByte(0)
    .AppendInt32(1)
    .AppendInt64(2)
    .AppendInt16A(3)
    .AppendSByte(4)
    .AppendString("something");

I suggest you to use SocketAsyncEventArgs in your network code, It's just a more scalable solution created especially for network server applications that require high performance such as a mmorpg server.

This looks really nice if you have a beta testing for it i would love to try it.

So its like how mta uses lua, and samp uses pawno?

Added XML parsing yesterday... well, it was already there, but was a temporary placement so i can load some configurations, so basically an improvement. Also updated some old shit, and worked a bit more on character details

Details of the updates:
http://jolte.codeplex.com/SourceCont...leCommits.aspx
http://jolte.codeplex.com/SourceCont...set/view/38372

Example of how i would use the XML before:

Code:

---

XML config = new XML();
string name = config.ReadValue("config.xml", "server-name");

---

now:

Code:

---

string name = "";
JoltEnvironment.GetXML("config").AssignValue("server-name", ref name);

---

Also can do multiple assignments at once

Code:

---

string name = "";
string location = "";
string expRate = "";

JoltEnvironment.GetXML("config")
    .AssignValue("server-name", ref name)
    .AssignValue("default-location", ref location)
    .AssignValue("exp-rate", ref expRate);

string[] coords = new string[3];
coords = name.Split(';');

RuneScape.GetConfig().ServerName = name;
RuneScape.GetConfig().ExperienceRate = double.Parse(expRate);
RuneScape.GetConfig().DefaultLocation = new Location(int.Parse(coords[0]), int.Parse(coords[1]), int.Parse(coords[2]));

PS. sorry for the slow progress, i really dislike having to work on such over the summer.

Haha, I understand :).

But AJ, I really have to admit, your really going at this. So far, the interface is amazing, the feel of the program feels, original and not overbearing. The source is so nice, I don't think I have seen a new C# Programmer make something this great. Nicely organized. Maybe someday people will respect me the same way they respect you, but I got awhile to go. If you ever need a little advice or help, you can always ask me.

Good luck AJ!

Thanks mate, always appriated these types of comments, makes me feel better what i'm working on, enforcing me to work more efficient etc :P

PS. here's a better explanation of the XML example i gave in my last post:

Awesome stuff AJ.
Its good to see your working on the internal stuff and tidying that up before working on the games features.
Good Luck with this! id love to follow it.
