[Pierre-Marie Baty]

Grenade entities are class-named "grenade", simply that

There are several ways to detect them, but this one will work:

   edict_t *pGrenade = NULL;

   // is there an armed grenade near here?
   while (!FNullEnt (pGrenade = UTIL_FindEntityInSphere (pGrenade, pPlayer->v_origin, 300)))
   {
	  if (strcmp ("grenade", STRING (pGrenade->v.classname)) == 0)
		 continue; // discard entity if it is NOT an armed grenade
 
	  // do stuff with grenade (check if bot can see it and check the grenade's velocity...
