Sounds to me like f60 is used to return the result of a ray vs. plane intersection point in 3D coords.




Yes, and when -2,2,1 is output instead of 2,2,1 then the ship collides with the right wall from inside the trench and with the left wall from the outside. But before the game gets there it obviously already knows where the wall and the ship is. This function just tells it which way to bounce the ship off, and it's kind of side effect it actually triggers collision reaction, that is loss of shield/energy beside the bounce, as this reaction, it seems, could be activated from the main function which calculated the ship intersects a wall in the first place.

In any case, the problem is there are no any input arguments to this function. I could get the ray from the ship's rotation matrix, but what plane, where does the function get this info from? Just like f15_swa that sets up camera rotation matrix and has no any input arguments, where does it get rotation angles from? I don't know where to even begin looking, don't know what is there to look at. Without Olivier there is only so much I can do by stabbing around in the dark. I only hope I dug up enough info so he can make sense of it and finally complete what he started a decade ago.
