  • Project Update #11 - Character Creation Screen - Jun. 11th 2016

    Hello everyone.

    As you can see, the forums are pretty quiet. This is because most of the chatter has moved to the Discord. I'm pretty active in the #psforever-code channel trying to dump my thoughts and current progress. Hop on if you want to chat regarding development.

    I don't have any real general announcements beyond the good news that the login server is completed enough for me to move on to the world server.

    Development Progress
    tl;dr - We can now login and create characters.

    We've hit some new milestones in the server development. We are now able to keep the PlanetSide client from disconnecting after a few minutes. This was fixed by figuring out the "Unknown{7,8}" packet pair. I don't know what this does, but I handle it enough to keep things from breaking.

    The next challenge was to handle logins to the PlanetSide world server. This required more reverse engineering and head scratching to get right. Using the GameCapture tool and previous captures, I was able to figure out the "magic" packets required for the client to enter in to the character creation screen. It's not 100%, but see below for a screenshot showing me at the character select.

    From here I began to handle some important character creation packets. This included character selection (hitting the "play" button), character deletion, and new character creation. I have now handled all of these packets just enough to allow the client to not fault.

    My immediate next goal is to figure out the scary "ObjectCreateMessage". This is a scary packet because of how complicated it is.
    I would consider this a "God" packet because it's responsible for so much. It is sent by the PlanetSide game server for EVERY game object that is created on the client. This includes your avatar, every inventory item, every terminal, every weapon, every vehicle, etc. It's "polymorphic" in that there are different ways of decoding it depending on what game object it represents! I have to make sense of this soup before I can start making my server create object on the server. The coolest part about this packet is once I understand it, I can spawn in any type of object on command. This means even strange objects or custom weapons!

    Once I figure out this packet, I want to get the client to enter a map. It's not currently working because I believe I'm missing some key packets (such as the avatar creation packet. you need to spawn in to something...).

    Initial efforts of getting past the server selection screen

    A hacked up character creation screen. It's faked because I was just replaying packets to get the client to create some characters.

    The furthest I've gotten so far. The client just hangs here.

    Development Log
    Here is the log of commits since my last status update. Lots of progress has been made! In total there were 45 commits with a total change of 58 files changed, 4074 insertions(+), 1586 deletions(-). Most of the development has been getting the critical world and login server packets reverse engineered and coded up. This takes a lot of time, but each packet adds new functionality.

    You can see the full commit log on the project Github.
