Hello, I'm trying to create a switch statement to simulate a conversation. Normally it works just fine because the previous possibilities are removed after choosing one. However, they are not removed on the mobile version. I can fix this by setting a case for when the result of the choice is not in the dictionary. Then it would just say you've already talked about that. But I can't figure out how to set that up. Here's the code:

ShowMenu ("Talk Options", IntroDanyel.talkTopics, false) {
  switch (result) {
    case (1) {
      msg ("Topic 1, OK!<br/>")
      dictionary remove (IntroDanyel.talkTopics, "1")
      IntroDanyel.talkRemaining = IntroDanyel.talkRemaining - 1
    }
    case (2) {
      msg ("Topic 2, OK!<br/>")
      dictionary remove (IntroDanyel.talkTopics, "2")
      IntroDanyel.talkRemaining = IntroDanyel.talkRemaining - 1
      dictionary add (IntroDanyel.talkTopics, "4", "Topic 4")
      IntroDanyel.talkRemaining = IntroDanyel.talkRemaining + 1
    }
    case (4) {
      msg ("Topic 4, OK!<br/>")
      dictionary remove (IntroDanyel.talkTopics, "4")
      IntroDanyel.talkRemaining = IntroDanyel.talkRemaining - 1
      dictionary add (IntroDanyel.talkTopics, "5", "Topic 5")
      IntroDanyel.talkRemaining = IntroDanyel.talkRemaining + 1
    }
    case (5) {
      msg ("Topic 5, OK!<br/>")
      dictionary remove (IntroDanyel.talkTopics, "5")
      IntroDanyel.talkRemaining = IntroDanyel.talkRemaining - 1
    }
    case (6) {
      msg ("Topic 6, OK!<br/>")
      dictionary remove (IntroDanyel.talkTopics, "6")
      IntroDanyel.talkRemaining = IntroDanyel.talkRemaining - 1
    }
    case (999) {
      msg ("Exit Convo, OK!<br/>")
      MoveObject (player, LivingRoom)
      IntroDanyel.leaving = true
    }
   case (null) {
      msg ("You've already talked about that")
    }
  }
  if (IntroDanyel.talkRemaining  >  0) {
    DanyelTalk1
  }
  else if (IntroDanyel.leaving = true) {
    IntroDanyel.leaving = false
  }
  else {
    if (DictionaryContains(IntroDanyel.talkTopics, "999") <> true) {
      dictionary add (IntroDanyel.talkTopics, "999", "Exit Convo")
    }
    DanyelTalk1
  }
}

EDIT: I thought I could add an if statement at the beginning to first see if the result was in the dictionary. That works, but then still causes an error. I'll poke at it some more.

EDIT AGAIN: I needed to call the show menu function again. It's not a totally ideal situation, but it works.

I don't use thus don't know about the mobile version, so I don't know what needs to be done (aka what type of workaround you need) for it to work for you.

------

though if you want to look at some code design methods of doing topics~events and removing~adding them as you select them, you can take a look at some of my works:

(see the ~ last posts of this thread: viewtopic.php?f=10&t=4224 )

my method is to use a List (String~Object) with a Dictionary (String~Object~Script), using "string comparison" (List's item String = Dictionary's item key String), to whether it activates the corresponding Dictionary's Value

thus, I can keep my Dictionary as a "database" for being "called upon" by the List.

alternating the List, for what can be activated in the dictionary, for (conceptual) example:

String List:
(1) dragon
(2) sword
(3) princess

Script dictionary:
dragon = msg ("d for dragon")
sword = msg ("s for sword")
princess = msg ("p for princess")

if (String List's String of "dragon" = Script Dictionary's String of "dragon"), then run the corresponding script: msg ("d for dragon")

well, what if I removed, "dragon", from the string list?

my "database" Script Dictionary is still intact, and also, I've eliminated the ' msg ("d for dragon") ' from running again. I've only altered my string list, which can be easily and quickly altered back to having "dragon" again.

anyways, here's two game codings of mine (though the "topic" game code doesn't have the list item removal code lines in it) that you can play around with (my "explore and travel" game code has all the elements that you want):
