SCUMM: MI1 (VGA) - Guybrush doesn't appear immediately at the 1st beach

Reported by: SF/sgt-nukem Owned by: AndywinXp
Priority: normal Component: Engine: SCUMM
Version: Keywords:
Cc: Game: Monkey Island 1

Description

(Latest CVS snapshot) ScummVM 0.9.0CVS (Nov 23 2005 11:41:50) Features compiled in: Vorbis FLAC MP3 zLib MPEG2

Windows XP SP2

Monkey Island 1 VGA - German / DOS

Details: When on the overlook Monkey Island map at the western coast south of the mountains, and from there clicking to the beach (where you first grounded when entering Monkey Island), it may be, that after changing to the beach screen, Guybrush needs minutes to actually enter the scene (or not enter it at all?!).

Reproducible: I think it's dependant on WHERE you click, because this strange bug doesn't occur always.

Just load my savegame. -> You will see the beach scene. But no Guybrush.

It may be that you could wait for hell freezing over without Guybrush appearing (didn't wait that long ;).

But if you do an action, like "watch the boat", Guybrush appears after approx. 20 seconds.

Savegame with strange "not-appearing"-bug

comment:1 by SF/sgt-nukem, 19 years ago

Actually it's more south-western than western coast.

It seems that this occurs if Guybrush is really near the coast. Maybe the screen changes immediately, but Guybrush still does pathfinding on the overlook map?!

In your savegame, Guybrush *is* visible, he's just outside the screen. His x coordinate has a negative value, i.e. he starts out at x = -640. He'll stay there forever, unless you make him walk, e.g. to watch the boat, which takes about 14 seconds over here.

Guybrush's position on the beach is determined by the point at which you enter the beach. Some calculations in the scripts will convert his position on the "map" to a position on the beach. It's possible that those scripts have a small subtle bug which causes this odd behavior when you are at precisely the correct spot before entering the beach...

But the savegame itself, I am afraid, is rather usless for debugging the issue. The interesting question is: Is there a way to reproduce this reliably? If you could provide a savegame on the map view where a single click on the beach reproduces the issue, that would help...

However, I think this is most likely a bug in the game itself, not in ScummVM

Mhhh... Since Nov. I played no further.

I just tried to reproduce it, but at first that didn't work.

But now I got it (I think).

Savegame attached. I posted a screenshot of where to click here -> http://img453.imageshack.us/img453/7233/monkey1wheretoclickforbug4db.png

It may be, that you first need to go northwest (to the round mountain basin), then change the map back, and from there just click to a point near the shown.

-> The screen changes IMMEADIATELY. But no guybrush.

Then click in the middle of the jungle, and after 20 sec (here) he shows up.

Then another strange thing happens: Before Guybrush actually enters the jungle, he makes some steps (animation) on the same spot (without moving) in front of the "jungle entry point"... :/ Weird.

fingolfin:

In your savegame, Guybrush *is* visible, he's just outside the screen.

>> Hey, for a user, this actually MEANS invisible. For a programmer, okay, if Guybrush.isVisible == true, this is visible, okay... ;)

I can reproduce this in the english MI1.

This happens if you click on the very bottom of the 'beach' object (number 26). That area is outside of walkboxes, and the closest walkbox is determined to be box 16, which is in the middle of the sea and unreachable. This makes you fail to walk there, and then immediately be moved to the beach room.

Testing tracker monitoring feature -- please ignore & sorry for the annoyance.

This still occurs and is quite easy to reproduce.
It happens every time if guybrush is heading top-left on the map and you click on the beach , around the area of the boat/tree, before he finishes walking.
Guybrush would increase his walking speed and then teleport to the beach at a negative out-of-screen coordinate.
The broken pathfinding also happens on DREAMM, he teleports to the beach (at a seemingly random location) but is never "invisible".

Should be trivial to add a workaround but maybe a cleaner solution could be implemented
