show variables on screen rpg maker xp
#1
hello there I was wondering if there was a script which could show a variable on screen in both combat and exploration this could be useful as both a score counter and if I wanted to create a ammo counter anyway any help would be greatly appreciated thanks

Why are people so adamant about scripts? This can easily be evented and won't bog down your game in the slightest.

Simply set up a global even to display pictures in the form of numbers. If a variable equals 1 then show the picture that looks like a 1.

If you really want however to stick to scripting, just quickly modify the gold box and replace gold with the variable(s) of your choice.

Yes let's write an 80 line long event and use up a bunch of our 50 picture slots just so we can show the player they have 30,000 GP.

...That was just me being grumpy! The real reason you shouldn't do these sorts of things in events is because of the overhead of the Interpreter. Doing one or three things with parallel process events won't matter, you'll start lagging if you do very many more than that. Best leave the event system for actual game control stuff. Also you can reuse scripts easily! For example, here I turned the first script I ever wrote (a script that shows HP and MP in a cute little window) into one that can show variables. It took me longer to write this post than it did to edit this script.

Code:
#==============================================================================
# **
#------------------------------------------------------------------------------
#
#==============================================================================

class Window_Variable < Window_Base
  WHICH_VARIABLE = 1 #change this to your variable number.
  #--------------------------------------------------------------------------
  # * Object Initialization
  #--------------------------------------------------------------------------
  def initialize
    super(0, 420, 640, 60) #the sets the X, Y, Width, and Height.
    self.contents = Bitmap.new(width - 32, height - 32)
    self.opacity = 200 #text (kinda transparent)
    self.back_opacity = 175 #backgrond (pretty transparent)
    #old value for checking if refresh needed
      @old_value = 0
    refresh
  end
  #--------------------------------------------------------------------------
  # * Refresh
  #--------------------------------------------------------------------------
  def refresh
    self.contents.clear
    draw_variable(0, 0)
  end
  #--------------------------------------------------------------------------
  # * Update
  #--------------------------------------------------------------------------
  def update
    #do we need to update?
    if $game_variables[WHICH_VARIABLE] != @old_value
      refresh
    end
  end
  #--------------------------------------------------------------------------
  # *  Draw Variable
  #--------------------------------------------------------------------------
  def draw_variable(x, y)
    self.contents.draw_text(x, y-16, self.width, self.height,
                            $game_variables[WHICH_VARIABLE].to_s)
  end
    
end

and now all you have to do is get Scene_Map to draw your window! Just do it like how the @message_window is done. in Scene_Map:

Find:
Code:
    # Make message window
    @message_window = Window_Message.new

Change to:
Code:
    # Make message window
    @message_window = Window_Message.new
    #Our new Variable Window!
    @variable_window = Window_Variable.new


Find:
Code:
    # Dispose of message window
    @message_window.dispose

Change to:
Code:
    # Dispose of message window
    @message_window.dispose
    #We need to free our window from memory.
    @variable_window.dispose


Find:
Code:
    # Update message window
    @message_window.update
Change to:
Code:
    # Update message window
    @message_window.update
    #This is called every frame so don't do anything crazy in updates
    @variable_window.update

You should study this script (and others, and the default ones) and learn how it works. And eventually you'll be able to code as well as me! Or at least make your own windows.

any help would be greatly appreciated in fact if you could just post your scenemap script thank would be great

I dunno! It works for me. Try it in a new project. If that works then you've got script conflicts (aka, more than one Scene_Map) try adding the window to a different Scene_Map

your right it seems it be some sort of conflict with the FPLE engine I am using but I found a script that does work with it thats your hud by emeraldcyndaquil see
[Image: yourhudshowoff.png]
I know I am asking alot but could you take a look at the script and see if you can't add a line to show a variable as well as the hp mp exp
Code:
class Window_YourHUD < Window_Base
  def initialize
    super(0, 0, 640, 64)
    self.opacity = 0
    self.contents = Bitmap.new(640 - 32, 64 - 32)
    refresh
  end
  def refresh
    self.contents.clear
    reset_variables
    return if !@actor
    draw_actor_hp(@actor, 0, 0)
    draw_actor_sp(@actor, 200, 0)
    draw_actor_exp(@actor, 400, 0)
  end
  def reset_variables
    @actor = $game_party.actors[0]
    @old_hp = @actor ? @actor.hp : 0
    @old_maxhp = @actor ? @actor.maxhp : 0
    @old_sp = @actor ? @actor.sp : 0
    @old_maxsp = @actor ? @actor.maxsp : 0
  end
  def update
    super
    refresh if (@actor = $game_party.actors[0] or
                @old_hp = @actor ? @actor.hp : 0 or
                @old_maxhp = @actor ? @actor.maxhp : 0 or
                @old_sp = @actor ? @actor.sp : 0 or
                @old_maxsp = @actor ? @actor.maxsp : 0)
  end
end
class Scene_Map
  alias yourhud_main main
  alias yourhud_update update
  def main
    @yourhud = Window_YourHUD.new
    yourhud_main
    @yourhud.dispose
  end
  def update
    @yourhud.update
    yourhud_update
  end
end
thanks again for trying to help

No, but I'll sure try to teach you how to do it! Teach a man to fish, etc. First off, I have edited that script to be more readable. I also fixed the "Stack level too deep" error you'd get if you pushed F12. Keep in mind this won't fix it if you have other scripts that alias things dumbly.

Code:
#==============================================================================

  end

  def refresh
    self.contents.clear

    @old_sp = @actor ? @actor.sp : 0
    @old_maxsp = @actor ? @actor.maxsp : 0
  end

  def update
    super
    refresh if (@actor = $game_party.actors[0] or
                @old_hp = @actor ? @actor.hp : 0 or
                @old_maxhp = @actor ? @actor.maxhp : 0 or
                @old_sp = @actor ? @actor.sp : 0 or
                @old_maxsp = @actor ? @actor.maxsp : 0)
  end
end
#==============================================================================
# ** Scene_Map
#------------------------------------------------------------------------------
#  We've edited this to add a HUD
#==============================================================================
class Scene_Map
  #---------------------------------------------------------------------------
  # * Alias Listings (fixes F12 bug)
  #---------------------------------------------------------------------------
  unless method_defined?(:yourhud_main)
    alias_method(:yourhud_main, :main)
    alias_method(:yourhud_update, :update)
  end
  #--------------------------------------------------------------------------
  # * Main Processing
  #--------------------------------------------------------------------------
  def main
    @yourhud = Window_YourHUD.new
    yourhud_main
    @yourhud.dispose
  end
  #--------------------------------------------------------------------------
  # * Frame Update
  #--------------------------------------------------------------------------
  def update
    @yourhud.update
    yourhud_update
  end
end

Step one, we need a way to draw the variable, so grab the draw_variable(x, y) method from my script and put in into Window_YourHUD. For it to work it has to go after the end of a method but before the def of another. So put it between
Code:
end
  #--------------------------------------------------------------------------

Now there are only three more steps! Next we want to tell the script to draw our Event Variable. So we add a call to our method, draw_variable(x, y). But where? See if you can't figure it out (HINT: look for other draw_stuff)


The next thing to do is to add our own variable to track the game's Event Variables. We do this because drawing something on-screen takes a long time and so we only want to do it if we need to (when the number changes).

Variables in ruby are made by typing a word. old_ammo would be a variable! We also have a thing called Scope, which means "who can look at my variable?" Putting an @ in front of a word means the entire class can access its value, and putting $ means the entire game can access it. So look at the reset_variables method, and add:
Code:
@old_ammo = $game_variables[WHICH_VARIABLE]
Now the whole Window_YourHUD can see the value of @old_ammo. Don't forget to change WHICH_VARIABLE to your Event Variable number.

Now we just have to modify the update method, so it can check our ammo and call refresh if it is different. The update method currently looks like
Code:
#---------------------------------------------------------------------------
  # * Update (called once a frame)
  #---------------------------------------------------------------------------
  def update
    super
    refresh if (@actor = $game_party.actors[0] or
                @old_hp = @actor ? @actor.hp : 0 or
                @old_maxhp = @actor ? @actor.maxhp : 0 or
                @old_sp = @actor ? @actor.sp : 0 or
                @old_maxsp = @actor ? @actor.maxsp : 0)
  end

Wait... what? I think we found a bug! This code says "Refresh if, oh but also set these old variables to the current value." I am assume the author mean to use == which compares two values, but even that is wrong. What we want is "Refresh if our old variables do NOT equal the current value" The current way is going to draw on every frame, which is going to cause lag. It SHOULD be
Code:
#---------------------------------------------------------------------------
  # * Update (called once a frame)
  #---------------------------------------------------------------------------
  def update
    super
    refresh if (@actor != $game_party.actors[0] or
                @old_hp != @actor ? @actor.hp : 0 or
                @old_maxhp != @actor ? @actor.maxhp : 0 or
                @old_sp != @actor ? @actor.sp : 0 or
                @old_maxsp != @actor ? @actor.maxsp : 0)
  end

Sorry, got off track... We need to add a Conditional! So it knows to refresh if our ammo changed. Can you figure out what we need to add?
Content Hidden

So now it should work!

Bonus: Maybe you want to make it say "Ammo: 12" instead of just "12"? Push CTRL+SHIFT+F in the script editor and search for "def draw_actor_hp". And then study how it is different from my draw_variable method.

Good luck!

THANK YOU THANK YOU SO MUCH!!!!!!!!!!!! it works perfectly I shall be sure to include your name in the games credits if this project ever gets finished I just spent the last hour going over your post and slowly figure out where to put things I really think I learned something Grinning
I don't suppose there is away it show that variable on screen during combat is there?

You could actually show the whole HUD if you wanted. Find your Scene_Battle and look for the main method. Then we just have to add a
Code:
@yourhud = Window_YourHUD.new
to it. Just look how that @status_window is controlled, and under any @status_window you find, do the same thing with @yourhud

so if the code says
Code:
@status_window.dispose
you add a
Code:
@yourhud.dispose
under it. And where it says
Code:
@status_window.refresh
add a
Code:
@yourhud.refresh

it should be that easy!
