A new command that allows skipping through time
in replays, and in-game (if cheating is enabled).

.skip <[+|f]seconds>
+: make the skip relative
f: skip to a specific frame

Examples:
.skip +60 -- skip 1 minute from the current time
.skip 600 -- skip to 10 minutes into the game
.skip f789 -- skip to frame 789

You can only go forward in time

all we now need is lua widget that shows the whole timeline and by clicking it makes it to jump there :)

So gamestates are saved per-frame now? Or does it just rush through the calculations for each frame without rendering?

Post by **hollowsoul** » 07 Mar 2007, 21:02

Guess its justs calculates to skipped time without rendering otherwise it be possible to go backwards

Post by **trepan** » 07 Mar 2007, 21:16

When resync is done, it may be possible to go backwards.
I did something similar for another game, and had the game
state saved every X number of seconds (configurable period).
You could jump to any time in a replay with a resolution of X.

If all that state is kept in the replay file, it gets much bigger. The
best idea is probably to leave the replay format as it is, and
create snapshots as you are viewing. The current skip forward
technique will still work (not as quickly as using stored state),
and you will be able to go backwards.

And something to keep noob hosts from using it to get their krogs ready faster...

i dont think you can have a timeline when you have no time limit

but i agree, we need some electrical shocks device attached to people who enjoy toying with speed ingame

could min/max speed be set to 1.0 by default?

Post by **trepan** » 07 Mar 2007, 23:32

quantum has released a widget that sets the min and
max speeds to 1.0 if the widget is run by the host player.

Isnt there a TASClient option that does the same via script.txt.
When hosting, although other clients unable to see if its set or not, since not in Lobby Protocol

In video, creating keyframe indexes - starting points for each jump regardless the direction - is key to keeping interlaced video properly aligned with the screen when making short jumps through it. Trepan has a good idea on how to solve the rewind issue. Create snapshots - keyframes - every 30-60 seconds. Enough to give some granularity in the replay, but not enough to kill playability.

In video, snapshots arent 20 mb

MadRat · Post by **MadRat** » 11 Mar 2007, 02:38

No shit, snapshots for video are a hell of alot bigger. Then again if they aren't bigger than 20MB then you probably aren't doing serious index support.

Post by **ILMTitan** » 11 Mar 2007, 08:04

I think he meant 20mb each.

MadRat · Post by **MadRat** » 13 Mar 2007, 04:27

As did I, 20MB of DVD quality video isn't really saying much of anything. I did plenty of 2 gig files in my early days of video editing back on a 486 with a miro card. A 20MB clip even in those cases of uncompressed jmpeg 320x240 interlaced video with embedded synchronized sound was a mere several seconds worth.

(Why did I stop at 2 gig? Because windows didn't support bigger ones at that time.)

If I'm not mistaken, uncompressed video is like having a snapshot every frame. Assuming several seconds means two, and twenty five frames per second, and negligible size for sound, that gives us about 410KB per snapshot, quite a bit less than 20MB.

Hmm, is there any real reason this couldn't be used as a backbone for saved games as well?

Is PAL only 25/sec? NTSC is 29.73/sec or something close to it. Don't forget interlaced is a pair of screens per frame, each pass slightly shifted off the other. The uncompressed video is not really a comparable format, I just captured in uncompressed because the cpu/miro technology of that day couldn't handle compression on the fly with any decent quality. Editing was done in format friendly compression depending on the media for the project.
