WINDTHRUST + wind + underwater = crash

Postby Player701 » Tue Mar 09, 2021 10:20 am

If a WINDTHRUST-enabled object is thrown into a Transfer_Heights-based deep water and the main sector has wind enabled (e.g. via Sector_SetWind), the game will crash. The crash happens here because player is null. It appears that the crash does not happen with 3D floor-based water.

Attached is a simple WAD to reproduce the issue. Just press the switch, and the game will crash as soon as the WINDTHRUST-enabled barrel reaches the water surface.

Tested in GZDoom 4.5.0 and g4.6pre-150-gb7bbfd4ef

I've made a PR: https://github.com/coelckers/gzdoom/pull/1335
I don't think it's worth doing more sophisticated calculations to check if the thing is actually wading.

That wind code is stupid as shit anyway, yeah no need to be more thorough for non-players.
