Fastprojectile 3d Floor misprediction

Post by IvanDobrovski »

Hello, I've recently stumbled upon this problem: https://zandronum.com/tracker/view.php?id=3337 which apparently happens in latest GZDoom as well, and was asked to report it. I hope this is the right place as I couldn't really find a bugtracker for GZDoom.

GZDoom stopped using its bugtracker due to lack of user engagement post-reporting, such as when more info was needed.

We use the forums now, so yes this is the right place.

With such a high speed? No wonder that it glitches at steep angles, because the stepping adjustment was only done on horizontal movement, but in this case it's the vertical movement causing the problem.

I assume calling GetZAt() to set the new z would address this?

No. What addresses this is taking smaller movement steps so that one move cannot skip a 3D floor completely.
