[Scripting Question] Adding and removing choices?

[Arachnee]

Hello all. I have been having trouble with this problem for some time now. I wish to make a list containing a collection of choices that can be added or removed from the list at will. I was hoping I could activate the options with a Switch, but that doesn't seem to work. The option i want to remove still seems to take up a sort of "space". And I can't seem to add anything to the list of choices. I'm not sure if I'm actually doing it right, and I don't know what else to try. How would one " push" and "pull" a choice into an array of choices? Thank you very much for any help in advance.

What does your code look like? I'd recommend copying how PScreen_PokemonStorage#pbStartScene works, i.e. (simplified):

            commands = []
            cmdSummary  = -1
            cmdDebug = -1
            commands[cmdSummary=commands.length]  = _INTL("Summary")
            commands[cmdDebug=commands.length]    = _INTL("Debug") if $DEBUG
            command=pbShowCommands(helptext,commands)
            if cmdSummary>=0 && command==cmdSummary   # Summary
              pbSummary(selected,@heldpkmn)
            elsif cmdDebug>=0 && command==cmdDebug   # Debug
              pbPokemonDebug((@heldpkmn) ? @heldpkmn : pokemon,selected,heldpoke)
            end

You can see here that the debug option is only added if $DEBUG is set. Is that what you're trying to do?

Oh yes, thank you. I think that's what I'm looking for. I will try it now.

I tried the code, but I keep getting an "undefined local variable or method 'command' " error. How do I fix it?

Again, you'd have to show your code to get any help. Although it won't be from me, you'll just have to go look at the code I was paraphrasing and work it out yourself. Or at the very least come back with some sensible questions, talking about undefined local variables suggests you don't know Ruby, but I don't have the time or inclination to teach you—try Googling.

EDIT: That was a bit harsh, but I really do recommend that you try to learn enough Ruby to understand what an undefined variable is; and also get into the habit of posting your code (short snippets rather than hundreds of lines).

Oh, sorry mgriffin.

Maybe using switches, yearh.

Check what FL did about his HUD script, to get "push and pull" effect, where the player press P buttom into overworld (if player haves at least one pokemon):

class Scene_Map
  alias hud_update update
  
  def update
    hud_update
    if Input.trigger?(Input::P) && $Trainer.party.length>0
      $game_switches[HUD]=!$game_switches[HUD]
    end
  end
end

Also, what he did about the code for switch:

    # When above 0, only displays HUD when this switch is on.
    SWITCHNUMBER = 0

    def showHUD?
      return (
        $Trainer &&
        (SWITCHNUMBER<=0 || $game_switches[SWITCHNUMBER]) &&
        (!DRAWONLYINMENU || $game_temp.in_menu)
      )
    end
