Combining Followers with PathLib OR A Feeble Attempt by Richard Headkid

Hello, all!

UPDATE: This didn't work out very well. See Pixie's guide here:

http://docs.textadventures.co.uk/quest/follower.html


EDIT:

Sorry, HK! I'll post the fix once I get it going. (Whatever I had going on interfered with the map, and I thought it best to take it down than risk causing anyone problems.)


awesome, thank you for posting this, will be of great help to a lot of people, we need a lot more public guides/libraries/codes for people to be able to use! As quest is such a good engine/software/program... but we've not made as many publically available guides/libraries/codes as we should have over the years.


Okay, I've got it working now.


Command: Asking it to follow

Command Pattern:

ask #object1# to follow #object2#;tell #object1# to follow #object2#;#object1#, follow #object2#

script

if (not object2.gender = "it") {
  if (HasAttribute(object1, "shadowing")) {
    if (object1.shadowing = object2) {
      if (object2 = player) {
        msg (object1.alias + " doubles the effort to follow you.")
      }
      else {
        msg (object1.alias + " doubles the effort to follow " + object2.alias + ".")
      }
    }
    else {
      object1b = object1
      unfollow (object1, 0)
      object1 = object1b
      object1.shadowing = object2
      if (object2 = player) {
        msg (object1.alias + " begins to follow you.")
      }
      else {
        msg (object1.alias + " begins to follow " + object2.alias + ".")
      }
      if (not (HasAttribute(object2, "followers"))) {
        object2.followers = NewObjectList()
      }
      list add (object2.followers, object1)
    }
  }
  else {
    object1.shadowing = object2
    if (object2 = player) {
      msg (object1.alias + " begins to follow you.")
    }
    else {
      msg (object1.alias + " begins to follow " + object2.alias + ".")
    }
    if (not HasAttribute(object2, "followers")) {
      object2.followers = NewObjectList()
    }
    list add (object2.followers, object1)
  }
}
else {
  msg (object1.alias + " can't follow an inanimate object.")
}

Command: Ask it to stop following

Command Pattern:

ask #object1# to stop;ask #object1# to stay;ask #object1# to wait;#object1#, stay;#object1#, wait;#object1#, stop

script

if ((HasAttribute(object1, "shadowing"))) {
  foreach (o, AllObjects()) {
    if (HasAttribute(o, "followers")) {
      msg (o)
      msg (o.followers)
      list remove (o.followers, object1)
    }
  }
  if (object1.shadowing = player) {
    msg ((GetDisplayName(object1)) + " stops following you.")
  }
  else {
    // msg ("IS shadowing:")
    // msg (object1.shadowing)
    msg ((GetDisplayName(object1)) + " stops following " + GetDisplayName(object1.shadowing) + ".")
  }
  object1.shadowing = null
}
else {
  msg ((CapFirst(object1.alias)) + " freezes in place.")
}

Script when entering a room

rh_last_room_shadowers

Turn script: followers THIS REQUIRES PATHLIB!!!

foreach (o, AllObjects()) {
  if (HasAttribute(o, "shadowing")) {
    npc = o
    // msg (o)
    targetroom = player.parent
    if (npc.parent <> targetroom) {
      list = PathLib_GetPath(npc.parent, targetroom)
      if (list <> null) {
        exit = list[0]
        npc.parent = exit.to
        if (npc.parent <> targetroom) {
          msg ((CapFirst(GetDisplayName(npc))) +" is in "+(GetDisplayName(npc.parent))+", and headed your way.")
        }
        else {
          diralias = ReverseDirection(exit.alias)
          if (diralias = "out") {
            msg (GetDisplayName(npc) + " arrives from the outside.")
          }
          else if (diralias = "in") {
            msg (GetDisplayName(npc) + " arrives from the inside.")
          }
          else if (diralias = "up") {
            msg (GetDisplayName(npc) + " arrives from above.")
          }
          else if (diralias = "down") {
            msg (GetDisplayName(npc) + " arrives from below.")
          }
          else {
            msg (GetDisplayName(npc) + " arrives from the " + diralias + ".")
          }
        }
      }
    }
  }
}

turn script: followers_entering

foreach (o, AllObjects()) {
  if (HasAttribute(o, "shadowing")) {
    if (not o.lastroom = player.lastroom) {
      msg ("Different last room. " + o)
    }
  }
}

Here's a link to PathLib. (This is the file I'm using with these scripts.)

I can't remember if I altered Jay's library or not.

Here's the link to the original PathLib source: http://textadventures.co.uk/forum/samples/topic/3214/path-library


Here's a link to my port in progress. I haven't copied over all the details of the game yet, but the followers do follow you correctly.

NOTE: You'll probably see testing messages print occasionally.
