Static analyzer found a small issue in ZDoom code inside EE

Recommended Posts

As you know EE uses ZDoom's 3D object clipping code, because it's pretty much the only 3D object clipping code ever written for DOOM that *just works*. But MP2E's static analyzer did turn up this, in EE's P_CheckPosition3D, which is curious:

612   // Nothing is blocking us, but this actor potentially could
613   // if there is something else to step on.
614   fakedblocker = clip.BlockingMobj;
      Value stored to 'fakedblocker' is never read
I wonder what this is supposed to do, and if it is indicative of a problem that may have already been fixed in ZDoom.

That code is as dead in ZDoom as it is in Eternity. It seems to be a leftover of something that either never got finished or was removed before any source containing it was released. Even the oldest source version I have containing this line doesn't do anything with it.
