[RGSS2/VX] Need help with this HUD.

[Jason]

Hey, so here's my code, pretty simple since I've just started it;

 

#==============================================================================

# ** Window_HUD

#------------------------------------------------------------------------------

#  This window displays the HUD

#==============================================================================

class Window_HUD < Window_Base

  #--------------------------------------------------------------------------

  # * Object Initialization

  #     x : window X coordinate

  #     y : window Y coordinate

  #--------------------------------------------------------------------------

  def initialize

    super(32, 64, 480, 96)

    refresh

  end

  #--------------------------------------------------------------------------

  # * Refresh

  #--------------------------------------------------------------------------

  def refresh

    self.contents.clear

    

    for actor in $game_party.members

      draw_actor_name(actor, 0, 4)

    end

    

    self.contents.draw_text(120, 0, 120, 32, "Hello")

  end

  

end

 

Obviously it's going to change and show more info when I've done, but I've got a few... problems/requests.

Right now, I've got it set to a common event, when a switch is turned on, the HUD shows up, and when I display text (Someone talking) I turn the switch off to remove the HUD so it doesn't get in the way, it's working fine with a common event, but having to place the event in every map seems like a pain in the arse, and I'd like to know how to do this through the script, since I can't remember how to do it, lol. Basically, simpler explanation, the HUD only shows while a switch is turned on.

Also, I don't like the windowskin around the hud, now I've tried changing this with back_opacity = 0, but that's just not giving me any results whatsoever, any help here?

Last question, how would I display an image in the window based on a variable? I'm trying to display hearts in it (Lives obviously), I'm wanting to include 3 hearts in a row, and like, if the variable (lives) is equal to 3, all 3 show up, if it's 2, get rid of one of 'em, if 1, get rid of 2 of 'em, and so on like that. I could do this with events and pictures, but I'd rather do it inside a script since it'd make my life easier... I assume.

So yeah, I've not got much done (It's basically just a copy/paste job from another window and change stuff, lol...), but hopefully with help, I'll have something presentable.

Edited...

[rgss]if $game_switches[11]
  @hud_sprite.visible = true
else
  @hud_sprite.visible = false
end if $game_switches[11] != @hud_sprite.visible
 
#or... simplified version
 
if $game_switches[11] != @hud_sprite.visible
  @hud_sprite.visible = $game_switches[11]
end

back_opacity only changes the opacity of the background of the central part of the window. opacity should make the whole window disappear if set to 0.

 

[Jason]

Okay, so first, for some reason opacity just isn't changing no matter what I try, seriously, I think I'm either missing a brain cell, or well, that's all...

Secondly, for some reason the if statement likes to scream at me and say that "[]" is an undefined method, which I've set to switch 3, when clearly it isn't...

 

[kyonides]

If you started using the if statement AFTER $game_switches is initialized (in Scene_Title, command_new_game method - when you're going to appear on a map and begin your journey), there's no reason it should be telling you it can't perform such a simple task.

Actually the if statement should be as simple as...

if $game_switches[11] != @hud_sprite.visible
@hud_sprite.visible = $game_switches[11]
end

 

[Brewmeister]

Actually, the if statement isn't even necessary. Just set...

@hud_sprite.visible = $game_switches[11]

 

[kyonides]

No, Brew, it's better only to use it with an if statement so it won't be updated every single time $scene.update is running... You should know about that.

 

[Brewmeister]

I assumed that the Sprite class tested the property to see if it changed before redrawing the sprite. (a fair assumption, I think)
