#819 closed defect (fixed)

DIG: Tomb repair-bot crash

Reported by: SF/magna Owned by: fingolfin
Priority: normal Component: Engine: SCUMM
Version: Keywords:
Cc: Game: The Dig

Description

Version : Win32 0.4.2cvs 2003-05-25

It's impossible to complete the generator repair puzzle in the tomb where you have to guide the repair-bot to pickup the lens form the bottom of the shaft and re- attach it to the generator.

After the bot performs the last action you have programmed ScummVM brings up the debug dialog with this message: Error: (26:2006:0x28F09): Invalid actor 180 in o6_wait:232.

Trying to continue from this by writing 'exit' just closes ScummVM. I haven't tried the newest official 0.4.1 build.

Here's also an gamesave.

Please provide a save game from before the problem. BTW it should work with ScummVM 0.4.1, we just made some check much stricter in CVS - this causes problems like this in a few places, which we are fixing step by step. While this is definitely a bit inconveniant for you (and us, too :-) right now, on the long term this should help improve the accuracy and stability of ScummVM. Thanks!

Oh that explains why the ScummVM homepage reports the game as completable and 85% done. Making the checks more stricter indeed helps out to refine ScummVM and in time improves the accuracy of the emulation. And this is one of the primary goals of ScummVM- to provide gameplay as close to the original as possible. That's indeed an good cause.

Here's the gamesave- it didn't attach to the thread last time I tried. I'll just continue playing after this has been fixed- who knows what I might bump into next.. I'm not in an hurry. =)

This one is really a big one. Something is fundaementally wrong regarding the o6_wait opcode (or rather its waitUntilActorTurned). I added a clean workaround for now, until we can investigate this in detail,

comment:8 by cyxx, 15 years ago

I was browsing the SCUMM engine code and saw that workaround. The disassembly doesn't show anything special for that opcode.

fingolfin, do you remember if that problem happens in other scripts ? Looking at script 27-2006, this clearly looks like a copy/paste error to me. What about making this workaround specific to the script and the game id (as it's usually done for other script bugs) ?

Ok, it has been confirmed this occurs in many other scripts. Thanks Kirben and Fingolfin.
