trace->fraction

[r00k]

I was messing around with this in SV_RecursiveHullCheck

Code: Select all

   if (trace->fraction <= p1f)
   {
      Con_DPrintf("SV_RecursiveHullCheck: trace->fraction <= p1f\n");
      return false;      
   }


and noticed that after a memset (&trace, 0, sizeof(trace));
like in void TraceLine (vec3_t start, vec3_t end, vec3_t impact)

the above condition fubar'd the chase_active code.
Which led me to initialize trace.fraction = 1; whenever i started a trace. Now is this good practice or just paranoia?

(BTW, it's 4:50am and i've been up all night so my brain is melting)

recursivehullcheck does not initialise the trace, you need to do that in the caller. Initialising fraction to 1 will cause it to go the full distance when it starts solid. It won't affect anything if it actually hits a wall.
