PETKA: Broken pathfinding
Reported by: | Tkachov | Owned by: | whiterandrek |

Priority: | normal | Component: | Engine: Petka |
Version: | Keywords: | pathfinding, walk | |
Cc: | Game: | Petka 1 |
Description
In ScummVM heroes sometimes choose a weird route when you ask them to walk somewhere.
Video demonstration: https://youtu.be/6fwc0zaqSTE (first 54 seconds are in the original game, the rest is in ScummVM).
There are no "Walk bug: Point doesn’t belong to any convex"
messages during that. They just happen to select a strange path instead of a more "natural" one, while in the original game they select the "natural" one.

ScummVM 2.3.0git11899-g3fb4d67b4e (Jan 16 2021 05:21:57)
Windows 10 version 20H2 64-bit
Petka 1.0.0.1 aka Red Comrades 1
To reproduce:
- load the save file;
- select 'Walk' cursor (right click, then left click on the purple silhouette icon);
- click somewhere (it seems if you alternate between above and below the fountain you could achieve this weird behaviour);
- <you would see the character go somewhat indirectly in ScummVM, but won't see that in the original game>.

Thanks
The problem is in that somewhere in the code it doesn’t match to dissasemly and it is very hard to find this glitchy part

Added the region render to this ticket:
Red line shows the outline and green ones show the inner polygons. I've heard characters can only walk from one polygon to the other through the their common edge, but I have no proof of that. Anyway, it's clear that character shouldn't go behind the fountain, but on the video you can see her doing it.
