my last message was something like "hey, while we reach the point at we can do anything, i ave few ideas and also i can start ripping the sprties". I know all this information raptor but thanks.

btw, any idea about internet gameplay? maybe the paintown project wich is opensource can help you...

Whenever Kat has slaved for long enough in my dungeon, as to make everything possible, shoot!

However, that is quite some time into the future, which is also why the guys have avoided thinking to much about features that far forward, except in some general ideas.

I looked at their milestone plan, and it was some good 2+ years forward in time before version 1.0, so I wouldn't exactly be holding my breath and run of to extract sprites just yet! :p

You can bet your .... donkey... that whenever they roll out V1.0 I'm going to redesign tournament mode! Then I'll need to learn to program to remove all the cheat code Kat and Vag have added, so that I always lose against them in multiplayer, since they know it is their only chance!

>=OD

Edit: Oh, they have tested a very early network code once before, and even gotten it to work (you can find the video on youtube, of Vagabond vs me, where the game refuses to let Vag win! Hillarious). Do note, that was an early version of the game (no combos, no hit blocks etc, just get in and spam first). And the netcode was so incredibly basic, that the clients didn't sync or anything. Basically my client told me I was alive, Vag's client told him that I had lost. Lots of hilarity.

They are looking at reimplementing it again, but are debating how it should be done.

Just posting this for Kat since he fell asleep before posting, but he managed to hammer up a new github automated webpage, and so I'll paste the link here:

http://omf2097.github.io/openomf/

For the most part contains the same information etc that the old links had, but is now a mite more user friendly etc.

I've been working the last couple weeks on network play, and today we merged the new implementation to master.

It is significantly different from the old approach (which was only a test) and it uses many of the same techniques as games like CounterStrike. I've tested it with latencies of up to 300ms, and it is choppy but playable.

It works like this:

Every time the client does something that changes the state of the HAR (walks, jumps, crouches, does an attack, etc) the game sends the sequence of inputs that triggered that change to the server.

The server then rewinds its own game state by half the ping time of the client, applies the actions the client provided and then fast-forwards the game state again, re-applying any inputs the other player had entered in the meanwhile.

Then, every time either HAR on the server changes state, the server snapshots the game state (mainly the HARs) and sends that to the client. The client discards its own game state, installs the new one and fast forwards it to compensate for the lag.

Thus we have both client side prediction as well as lag compensation. It can still be a little choppy, because we don't interpolate positions when recreating the game state, so client side prediction errors can manifest as the HARs abruptly changing position.

The good news is, however, that the server and the client are rarely out of sync for long, so there's no more disagreements about if a move hit or not.

I'd post a video, but I can't find anyone to help me playtest it

i can help you! hehehehe

Kat just posted some experimental binaries:

http://users.jyu.fi/~tutavirt/projects/openomf/packages/

You just need to put the OMF game data in the 'resources' directory to make it work.

If you're serious about testing, hop on IRC: #omf on Freenode. Raptor has some web interface for it here:

http://www.omf2097.com/chat/

It'll be a lot easier to coordinate in real-time.

Just wanted to share my new record for high-score in OMF ;)



Was a tiny bug in the code, and Vag has already fixed it, so never mind! :)

So, we recently figured out how scoring, combos and move chaining work (where you can break out of the recovery of one attack into another). There's also a bunch of smaller stuff, like shadows that have been added. Thus, a new video:

Still lots of bugs, but it is actually starting to resemble the original.

Thank you so much for this release! I'll try to betatesting some characters in order to help you searching for errors. Maybe you know all, maybe you don't know it all but i only want to help a little.
