How do you disable something in command window?

[Gando]

Hi, i was just wondering, how could you disable something in command window in the menu, like disable the skill option or save option, and then when a certain switch is on, the option is added back to the menu.
I don't mean disable so that the "save" text turns gray and when you try to select it you can't but disable it so that you can't se it at all. I've tried to play around a little bit with the menu but i can't figure it out, when i try it my way the menu ends up being buggy :shock:
Thanks :smile:

    @a_disabled = []
    gand_disableitem_window_command_initialize(width, commands)
  end
  #--------------------------------------------------------------------------
  # * Disable Item

  #--------------------------------------------------------------------------
  def disable_item(index)
    gand_disableitem_window_command_disable_item(index)
    @a_disabled << index unless @a_disabled.include?(index)
  end
  #--------------------------------------------------------------------------
  # * Disabled?
  #     index : item number
  #--------------------------------------------------------------------------
  def disabled?(index)
    return @a_disabled.include?(index)
  end
  #--------------------------------------------------------------------------
  # * Enable Item
  #     index : item number
  #--------------------------------------------------------------------------
  def enable_item(index)
    return unless @a_disabled.include?(index)
    @a_disabled.delete(index)
    # Clear out he part we are drawing too.
    self.bitmap.fill_rect(0, index * 32, width, 32, Color.new(0, 0, 0, 0))
    draw_item(index, normal_color)
  end
end

Ok when you disable an item its index is stored inside the class. So before you figure out whether a command is disabled call disabled?. That will return a true if its disabled or false if it isn't. Let me know if there's any trouble. I also added a method to enable an item if that ever comes up.

[edit]I should probably wait until I write out everything I want to say  :smile:

To install this script just insert an empty section above Main in the script editor and paste in this code. It doesn't override any methods so there shouldn't be any trouble with other scripts unless they do something drastic to drawing behavior. In which case enable item would need to omitted. Anyway and as always.

Good luck with it Gando! :thumb:

Thanks for all the help Khmp, i really appreciate it!  :thumb:
Iv'e inserted the script above main, but i don't really understand how i disable something from the menu..  :down:
let's say that i would like to disable the "skill" command, how would i do that?  :neutral:

ugh.. i wish i would have started learning to script waaaaay long before i did, then i would probably have known this by now ^^

 

[khmp]

Alright is that Scene_Menu?

 

[Gando]

yeah, it's Scene_Menu.

 

[khmp]

This code will be intrusive. It overrides main and update_command. Just create another empty section above main below that command code I gave you  up top. There is a constant integer which determines the switch that decides whether the "skills" are disabled. Right now its set to 1. You can change it to whatever. But I'll be honest that kind of eliminates the need for the additional Window_Command code I made. :lol:

Thanks, but it wasn't exactly the thing i was looking for, i want it to disapear  so you can't see it at all, not just make it unavailable and make the text turn gray :wink:

But i played around a bit and i got it to work, kinda..
The whole, "remove skill option if switch isn't on" thing works great, but when the skill option is available, when you choose something in the menu and then go back, the cursor goes to the option above, so if you choose equip and then go back the cursor will end up at skills instead of equip.

Here is the menu script i made:

end

and then in Scene_Equip, Scene_Status, Scene_Save  and  Scene_End i edited the "# Switch to menu screen" thing, so now it says for exampel:

Scene_Equip

    if @skill_enabled
      $scene = Scene_Menu.new(2)     
    else
      $scene = Scene_Menu.new(1)
    end

you know what, i'll just post a demo, i think that is easier:

Demo : http://www.box.net/shared/2agu60fcos

So what i would like to know now is,  how can you fix the cursor position thing when you go back? :shock: :tongue2:

 

[khmp]

This line inside the else of testing @skill_enabled is the trouble:

@command_window.index = @menu_index

Because the skill command has been removed the indexing beyond 0 are now -1.

@menu_index -= 1 if @menu_index > 0
@command_window.index = @menu_index

That should fix that.
