Summary0001818: Extreme slowdown on hero movement after revealing entire map (pathfinder?)
DescriptionTo reproduce:
- Load map "Thousand Islands"
- Move your hero around island (everything OK)
- reveal entire map via vcmieagles
- Try moving hero again. At this moment movement becomes extremely slow consuming all CPU power.
- Board ship at south-east corner of island, using vcminahar if needed
- Hero movement seem so be back to normal

Probably pathfinder does not reacts well to huge water spaces when there is available ship in vicinity.

It may be similiar to already fixed bottleneck in adventure AI, will check.

Is this still an issue?

I've compared both versions(0.95c and 0.97b) and it seems that issue has gone. In VCMI 0.95c moving hero was doing small delays between tiles, and in current version he doesn't. But there still is something like small freeze every time hero is ending his move. That slowdowns are quite well visible on the map which I'm including, just repeat the same steps in description. I'm not sure if it can be considered as a new issue, if yes, I'll create one.

Updated pathfinder I just merged should already be much faster as we fixed multiple bottlenecks, but there also work on separate thread:
https://github.com/vcmi/vcmi/pull/138 [^]

If threading implemented pathfinder won't affect client responsiveness even on super-slow devices.
