I'm having a bit of trouble getting missiles to hit the owner, in g_runmissile() in g_missile.c

Code:
   BG_EvaluateTrajectory( &ent->s.pos, level.time, origin );

   
   if ( ent->target_ent ) {
      passent = ent->target_ent->s.number;
   }

   else if (ent->count)
   {
      passent = ENTITYNUM_NONE;
   }

   else {
      passent = ent->r.ownerNum;
   }
   
   trap_Trace( &tr, ent->r.currentOrigin, ent->r.mins, ent->r.maxs, origin, passent, ent->clipmask | CONTENTS_TRIGGER);

   if ( tr.entityNum != ENTITYNUM_NONE )
   {
      
      traceEnt = &g_entities[ tr.entityNum ];

      if((strcmp(ent->classname, "hook")) && (strcmp(ent->classname, "althook")))
      if(g_telemissiles.integer)
      if ( traceEnt && traceEnt->s.eType == ET_TELEPORT_TRIGGER ) {
         trigger_teleporter_touch ( traceEnt, ent, &tr );
         return;
      }

      if((strcmp(ent->classname, "hook")) && (strcmp(ent->classname, "althook")))
      if(g_bouncepadmissiles.integer)
      if ( traceEnt && traceEnt->s.eType == ET_PUSH_TRIGGER ) {
         trigger_push_touch ( traceEnt, ent, &tr );
         return;
      }
   }

   
   if ( tr.startsolid || tr.allsolid ) {
   
      trap_Trace( &tr, ent->r.currentOrigin, ent->r.mins, ent->r.maxs, ent->r.currentOrigin, passent, ent->clipmask );
      tr.fraction = 0;
   }
   else {
      VectorCopy( tr.endpos, ent->r.currentOrigin );
   }

   trap_LinkEntity( ent );

   if ( tr.fraction != 1 ) {
      
      if ( tr.surfaceFlags & SURF_NOIMPACT ) {
         if (ent->parent && ent->parent->client && ent->parent->client->hook == ent) {
            ent->parent->client->hook = NULL;
         }
         G_FreeEntity( ent );
         return;
      }

      G_MissileImpact( ent, &tr );
      
      if ( ent->s.eType != ET_MISSILE ) {
         return;      
      }
   }

   if (!ent->count) {
      trap_Trace( &tr, ent->r.currentOrigin, ent->r.mins, ent->r.maxs, ent->r.currentOrigin, ENTITYNUM_NONE, ent->clipmask );
      if (!tr.startsolid || tr.entityNum != ent->r.ownerNum) {
         ent->count = 1;
      }
   }

   if(trap_PointContents (origin , -1) & MASK_WATER)
   {
      if(ent->s.weapon == WP_PLASMAGUN)
      {
         G_ExplodeMissile(ent);
         return;
      }
   }

   G_RunThink( ent );


The code above works provided I don't make the missiles shootable in the actual fire function, I think it might have something to do with the r.maxs and r.mins. If I do make the missiles shootable, the missile explodes immediately after being fired.


Code:
bolt->health = rocket.health;
      bolt->takedamage = qtrue;
      bolt->die = G_MissileDie;    
      bolt->r.contents = CONTENTS_SHOOTABLE;
      VectorSet(bolt->r.mins, -10, -3, 0);
      VectorCopy(bolt->r.mins, bolt->r.absmin);
      VectorSet(bolt->r.maxs, 10, 3, 6);
      VectorCopy(bolt->r.maxs, bolt->r.absmax);

not a coder so i'm probably talking bollocks, but wouldn't you need to let the missle fly for a second or two before it thinks about a target?

Probably. I tried incorporating a wait into the missile without much success, they just explode after the wait has expired.
