Join back the game after crash

[alexmic]

Hi guys

The feature I miss the most is the possibility to come back to the game after it has crashed.
I've seen it in many games and I think it would be a great improvement in spring.

I know it might be a hard stuff (sync again and bandwidth)...

Thanx for your attention and you efforts in spring

Cheers

This would be really hard to do.

would it not be possible to DL the replay file from the host, fast forward it to current gamestate, and then .give the dropped team back to the player ?

or you could make it possible to save the game or have it autosave.

means 20-30 secs of inactivity every nth minutes of game, players would get quite frustrated

lol, i fail to understand that,

the server would just have to send a copy of all its current information to the client joining...

literally a snapshot, then just run the connection as normal...

[imbaczek]

the problem is that this snapshot can weigh in at several hundred megs.

[SinbadEV]

a snapshot is basically the current Memory usage of spring.exe (RAM and swap)

[aegis]

why are save games so small?

isn't a lot of the stored data unsynced?

[SinbadEV]

the replays are basically the netcode (a list of commands) and then the game is extrapolated... not sure why games saves would be small... I would guess if you paused the game to let people rejoin another players saved game would probably suffice.

[imbaczek]

good catch, I dunno ^^ maybe it's not *that* much stuff.

No, it wouldn't have to include any loaded textures or models or sounds, just everything in the sim.

A saved replay for even a large game is 2-3MB or so. So theoretically , the server could pause, send the replay to the client, which runs it at full speed with graphics off to get to the same state as everyone else. Then unpause and continue.

The problem is implementing this in spring is not as easy as that. However, it would probably be easier than writing a full save/load system. It's been on the wish list for a long time, but it's a big task...

[alexmic]

I was just wondering if reconnect could actually be handled like a huge ping...

Sometimes we see players with outrageous pings (i.e. > 5 secs) and the player can resync in secs when the game is paused...

So when the player joins back, pause the game and resync ?

I know it is quite the same idea as stated earlier but, I think the pausing stuff could remove a point?

Continuing the sim in one thread while saving it in the other?
