ULTIMA8: Bentic talks to himself during conversation

[vvs-]

During conversation with Avatar Bentic keeps talking to himself while reading a book. This corrupts parts of the conversation text.

SCUMMVM commit 55a7e05439b6204bd7f9e62e568cc32dda772359 on Linux.

Thanks for the report - I will take a look at this. I think this it's the same problem as Darion walking around the training area while you try to talk to him - the scheduled actions should be paused while talking so I have to work out how that happens in the original.

AFAIK this should be the same in all Ultima games, so you can make NPCs to skip their schedules entirely by talking to them at the right moment. This can be used to cheat or workaround bugs, e.g. before Dermot stuck in the inn in Ultima IX's Britannia.

I had a deeper look at the usecode(script) and disassembly last night but nothing jumped out as the reason these events should be blocked. Obviously they are in the original game though, I just have to work out how. Some notes for my memory:

• Use and Schedule event code are the same as the disassembly of the original game
• Usecode class ids are all correct (adjusted from shape nos as the original game does)
• Implementation of 0x78 (exclude) opcode is correct
• BENTIC::use() is exclusive proctype 0x207 but has no other code to stop other things happening
• BENTIC::enterFastArea() spawns BENTIC::3A25, which randomly spawns BENTIC::3AA1 (proctype 0x205) where he barks the book reading notes ("I never knew that..", "Fascinating!" etc)

I played with this some more and I'm having trouble reproducing the problem. Do you know if it's possible to do anything particular before talking to him that causes it to happen?

Now that you've said it I found it difficult to reproduce, indeed.

From my many attempts only few succeeded. It seems that it depends on Bentic's animation frame, though. If he is motionless then I can't reproduce it, and when I click on him while he turns pages he seems to continue talking. But I'm not absolutely sure, of course.

Dropping priority as it's a fairly minor bug and seems hard to reproduce.
