Action recorder

Reported by: SF/h00ligan Owned by: sev-
Priority: normal Component: --Other--

This patch implements record and playback of scummvm game progress.

- every backend must delete eventManager instance (as I already implemented for SDL)
- all random sources must be registered with eventManager by unique name

Recorder patch

comment:1 by sev-, 12 years ago



in scummvm.ini

Play game


and run scummvm with same target again. It will playback recorded sequence.

It will create 3 files in savepath:


and record.tmp, which is a temporary file, but can not be removed due to lack of functionality in our File class

This works just fine on wince (scumm games tested) with a small patch (follows - I didn't attach it because it's trivial) and the savepath variable defined. Possible enhancements include: per-game/user naming for saved files, start-pause-stop playback, gui for it. good work!

Max, any opinion about the code?

Just tried this patch and it seems to work nicely for the most part.

Here's my feedback:

- Something went wrong the first time I recorded me playing BASS: during playback it seemed to skip one (or more) mouse-clicks I made about 1 minute into playing, causing the playback to behave strangely as Foster didn't enter the door like I did when it was recording, and now it was subsequently performing clicks and mouse-movements that should be performed in the next room.
I was able to consistently reproduce this using the same replay file.
Afterwards I tried a few times to reproduce this with a new recording, but wasn't able to (and unfortunately the original replay file that exhibited the problem was since overwritten).

- During playback I tried to move the ScummVM window by clicking its decoration/title and dragging it, but found that while attempting this that it seemed to receive all kinds of mouse-move events (presumably from the playback), thus causing the window to warp around my desktop(s) like crazy.
I'm using the XFCE4 window manager on if that matters.

Eugene: Sorry, I didn't have a chance to look at this yet.

Note that readRecord / writeRecord write structs in one go. This is not portable, and also not future safe.

I modified patch as following:

- Made it compile with current SVN
- Extended it to new engines
- Added command line options
- Fixed crash when record files do not exist

Still some work is needed in this direction:
- Try to avoid warpMouse() calls at playback, so the system will be useable
- Perhaps we need to indicate recording mode. May be draw triangle/circle in some corner. Use OSD overlay for that
- Still it is possible that time will drift away even with current implementation. Do something about it
