Help me test:

[Scott Richmond]

Started a 3D server.

[Josh]

Thanks, but your router isn't allowing connections. Download version 5 (above) if you see this, and join my server.

[Scott Richmond]

Give it a crack now.

[Josh]

Version 6 is available. This interpolates motion between three data points.

[Marleys Ghost]

Trying now.

[Josh]

Version 7 is available. I came up with a motion smoothing technique that is so simple and so effective. I am eager to see how it performs, so find me on one of the chat servers now!

seem link for chat12 is broken

 

thanks

[VicToMeyeZR]

yup. link broke

[Niosop]

It should be http://www.leadwerks.com/post/chat12.zip

[Marleys Ghost]

It should be http://www.leadwerks.com/post/chat12.zip

 

 

Yep, that works

[Rick]

Who has the Duke Nukem Forever server? It doesn't seem to connect me.

 

 

I created my own server and I have to assume the controller is server side. I'd like to try it on a different server.

This is really exciting! What method do you use to sync all of the objects within the world?

 

(started a server)

[Josh]

Version 16 is up. If anyone is on the west coast (US) I could use your help testing.

[Rekindled Phoenix]

getting new version now...

 

v16 can be found HERE:

[Paul Thomas]

Dead download link for me.

[Rick]

Copy this link and just change the number of what josh says at the top post

 

It should be http://www.leadwerks...post/chat12.zip

[Niosop]

He always forgets the /post/ So should be http://www.leadwerks.com/post/chat16.zip

I'm really enjoying this little app

[Josh]

Okay, version 17 fixes the synced entity deletion issues that were causing crashes when a client left. I also added a check so the client will be rejected from the game if the network protocol versions don't match.

[Rekindled Phoenix]

Get v17 here

[Rick]

I didn't try 17 but if all you said is what changed from 16 above, there was a noticeable delay from when I pressed my move keys to when I saw the movement happen. As we talked about before I assume you are just sending the move key to the server and having the server do the physics and sending back the position to the client. My ping was 110 which is what it is for nearly every online game I play. I'm sure you are well aware but client side prediction will be required. It sucks to have to jump through that hoop, but it's a reality in online games today.

 

Remember that post someone made about that box that was going to let you play any game online and it would stream the games to your tv/computer as you're playing them so you wouldn't need any local installs of the game? I can't remember the name, but this is the reason everyone said it was basically impossible to do it because there wouldn't be any client side prediction and there would be noticeable lag between when the player pressed an action button and saw the action being done.

 

It's basically impossible to not have client side prediction because even when I created my own server (which you can't get faster than that) I noticed a slight lag between my key presses and movements and players just wouldn't accept that these days.

 

 

I'm sure you are aware of this and I'm sure you'll figure it out. Baby steps first. Learning as you go I'm sure. I didn't enjoy trying client side prediction with the character controller. I ran into all sorts of syncing issues when trying to implement the player physics on the server and on the client. That's why I think it's just easier to have the physics run on the client for just their character controller. Then that sends the data to the server and on the server all characters are just doing SetPosition() to the position the clients said they were. Obviously there would need to be server checks to make sure the last position and current position of the players is reasonable and they aren't hacking. NPC's would have physics run on the server and position/rotation send to clients where the clients would just do SetPosition/SetRotation.

 

The other issue with doing it this way is that I'm not sure how to cause physics interactions between objects and players. If I threw a barrel at a player but on my side the player is just getting SetPosition/SetRotation called, when it hits the player on my side there would be that noticeable lag between when I see the physics happen.

 

Again though, this is most likely why nobody has good networked physics. There are just so many issues around it.

At least version 15 worked very smooth with 300ms ping and 8 packets per sec. I have to check if version 17 is different.

[Rick]

What was smooth? The dropping of barrels was great, but the moving of the character controller wasn't "smooth", in that there was a delay when when you pressed the move key vs when you actually moved.
