[17:40] <rdg> is the debug console available over a tty/port rather than in the game display?
[17:42] <rdg> stdin from the scummvm process is not connected to the debugger console
[17:43] <grogbot> [discord] <ccawley2011> You can compile ScummVM with `--enable-text-console` and it'll use the terminal for input instead.
[17:45] <rdg> ccawley2011: thanks!
[17:59] <Scummette> [scummvm] sev- closed pull request #4667: SCUMM HE: Disable save compression for Moonbase. (master...fix-map-saving) https://is.gd/AwBdWY

[17:59] <Scummette> scummvm/master d30af5e LittleToonCat: SCUMM HE: Disable save compression for Moonbase.
[18:13] <rdg> in the director debug console, I can see a local variable: WhichCursor - [STRING] "Pointer"
[18:13] <rdg> but using "print WhichCursor" crashes the session, is this the correct way of printing its value?
[18:33] <Scummette> [scummvm] mgerhardy pushed 15 new commits to master: https://is.gd/Fxn595
[18:33] <Scummette> scummvm/master 4f67eda mgerhardy: TWINE: replaced setAngleCamera

[18:33] <Scummette> scummvm/master 611722d mgerhardy: TWINE: continue renaming
[18:59] <grogbot> [discord] <sev> "put WhichCursor"
[18:59] <grogbot> [discord] <sev> but that is interesting that there is a crash
[18:59] <grogbot> [discord] <sev> I'll check
[19:06] <rdg> not sure if its a crash, it only exits with 1
[19:06] <rdg> only happens after: WARNING: BUILDBOT: b_getProp: list arg should be of type ARRAY or PARRAY, not VOID!
[19:06] <rdg> if I put a bp before it prints it fine
[19:07] <rdg> I just found two blopper videos hidden in the game xd

[19:25] <grogbot> [discord] <danielalbu> 🎙 Join us in 30 minutes for my conversation with ScummVM project leader Eugene Sandulenko!
[19:25] <grogbot> [discord] <danielalbu>
[19:25] <grogbot> [discord] <danielalbu> We'll be discussing reverse engineering, speedrunning, Blade Runner (1997), ScummVM 2.7.0, Macromedia Director, DREAMM and more!
[19:25] <grogbot> [discord] <danielalbu>
[19:25] <grogbot> [discord] <danielalbu> @sev will join us in the live chat during the premiere!

[19:37] <rdg> so... the Discovery Channel crew added a hidden video from the 70' of dead whale exploding on the beach in the game Operation Eco-Nightmare
[19:38] <rdg> with the hint "sometimes reality exceeds fiction"
[19:40] <sev> oh, that is interesting
[19:40] <sev> is the b_getProp error happening after your debug command or during the normal playback?
[19:41] <rdg> it happens during normal playback, but there are a bunch of other problems before that point
[19:43] <sev> aha. So it, is "Operation Eco-Nightmare" game, right?
[19:43] <rdg> here is the log: http://ix.io/4mxw
[19:43] <rdg> yep
[19:44] <rdg> I will probably need to implement findSys blitPict and batQT xlibs
[19:44] <sev> oh yes, globalvars warnings could be important, but also there are 3 Xlibs
[19:45] <rdg> yeah, not sure why those global warnings
[19:45] <sev> judging by their names, they could be relatively simple to implement, but in any case, they have to be implemented too
[19:46] <rdg> I think those warnings may come from the FlushGlobals function
[19:46] <rdg> which saves those variables as locals, calls clearGlobals() and resets them
[19:46] <rdg> but at the beginning they don't exist
[19:47] <rdg> here http://ix.io/4mxx
[19:47] <sev> that sound like it could be safely ignored then
[19:47] <-- ny00123 left irc: Ping timeout: 252 seconds
[19:47] <sev> ah, yes. Then it is understandable and could be ignored
[19:48] <rdg> yeah, I think so
[19:48] <sev> and my understanding is that b_getProp error is related to the batQT Xlib
[19:48] <sev> since it is not implemented, we return VOID
[19:50] <rdg> here is the bt: http://ix.io/4mxy
[19:51] <rdg> in the line: set CursorStartCast to integer(getProp(InvCursorCastNums, WhichCursor))
[19:51] <Scummette> [scummvm] neuromancer pushed 1 new commits to master: https://is.gd/nc8An1
[19:51] <Scummette> scummvm/master e320b7d neuromancer: FREESCAPE: UI fixes for zx and cpc releases of driller
[19:51] <rdg> InvCursorCastNums is void
[19:51] <sev> do this
[19:52] <sev> 1. Create directory named 'dumps'
[19:52] <sev> 2. Run ScummVM with --dump-scripts command
[19:52] <-- risca left irc: Ping timeout: 256 seconds
[19:52] <sev> it will dump all scripts to that directory
[19:52] <sev> and you may search and find where that InvCursorCastNums is set, etc
[19:53] <rdg> well I used the ProjectorRays tool to get the source
[19:53] <sev> same stuff, could be even easier
[19:54] <sev> ...or better, if there are only bytecode scripts, not the originals
[19:54] <sev> I wish that some day we build ProjectorRays in
[19:54] <Scummette> [scummvm] neuromancer pushed 7 new commits to branch-2-7: https://is.gd/rP7BrV
[19:54] <Scummette> scummvm/branch-2-7 6a7683f neuromancer: FREESCAPE: implemented skanner in driller
[19:54] <Scummette> scummvm/branch-2-7 3f7dd38 neuromancer: FREESCAPE: implemented SETVAR instruction
[19:54] <Scummette> scummvm/branch-2-7 0a837ed neuromancer: FREESCAPE: stop execution if some instruction is not implemented (except in castle)
[19:54] <rdg> yeah, but the bytecode is harder to read
[19:55] <rdg> I'm checking the dumps
[19:55] <rdg> and is only set in one place
[19:55] <rdg> in the InitInventory
[19:55] <rdg> which is never called
[19:56] <rdg> placed in exitFrame()
[19:56] <sev> yes, I am telling exactly this. E.g. if the scripts were stripped off and only bytecode is left, then ProjectorRays is the way to go today
[19:57] <sev> ScummVM cannot decompile scripts at this moment and only shows bytecode
[19:58] <rdg> I see
[19:58] <rdg> one thing
[19:58] <rdg> they use this technique:
[19:58] <rdg> set ToDo to "set InvCursorCastNums = " & the text of cast "InvCursorCastNums"
[19:59] <rdg> do(ToDo)
[19:59] <rdg> to set the InvCursorCastNums
[19:59] <sev> yes, it is a frequent approach in Lingo
[19:59] <sev> as long as InvCursorCastNums is declared global, it should work
[19:59] <sev> and if it does not, then it is our bug
[20:00] <rdg> but I only see it being modified by one function, InitInventory
[20:00] <rdg> and is never called, before the setCursor() attempt to call getprop(InvCursorCastNums, ...)
[20:01] <rdg> can this be ok in Director?
[20:02] --> ny00123 joined #scummvm.
[20:05] --> risca joined #scummvm.
[20:31] <rdg> so, getProp exiting via this TYPECHECK2: https://github.com/scummvm/scummvm/blob/master/engines/director/lingo/lingo-builtins.cpp#L880
[20:31] <rdg> in this return: https://github.com/scummvm/scummvm/blob/master/engines/director/lingo/lingo-utils.h#L41
[20:31] <rdg> leaving the stack empty
[20:32] <rdg> and next the integer() function is called
[20:32] <rdg> but there is nothing in the stack
[20:35] <rdg> as the getProp doesn't return anything, the debugger is triggered
[20:36] <rdg> can I push a dummy integer value to pass it to the integer() function from the debugger?
[20:37] <rdg> my theory is that the code that initializes the InvCursorCastNums variable will be called later (and that this is a bug in the original game)

[21:52] <grogbot> [discord] <madmoose> @sev, @danielalbu Great interview, both of you 🙂
[21:52] <grogbot> [discord] <eientei> Do we have anything to extract the .red files for like RTZ?
[21:53] <grogbot> [discord] <sev> Any feedback is welcome
[21:54] <grogbot> [discord] <sev> Probably not stand alone, but you can relatively easily take those from the engine code

[23:59] <grogbot> [discord] <Bosca> I'd like to give a shout-out to the devs of our Blade Runner engine, I began playing the game two days ago for the first time ever and I'm having already having a blast! 😄 Also, this reminds me that I have to catch up on sev's interview! @danielalbu's interviews are always great, so I can't wait to sit down and watch this one in particular 🙂
