HUD help

[Luthur]

OK, I need some help with adding a weapon cycle to a HUD I've edited, and a bit of help on displaying the actual HUD. I've got the HUD mainly sorted, but here's what I've got for the weapon cycle:

    # If Q button was pressed

    if Input.trigger?(Input::L)

      # If event is running, or menu is not forbidden

      unless $game_system.map_interpreter.running? or

             $game_system.menu_disabled

 

Then after that I need some help with the code. What's the code for changing the main player' equiped weapon?

Then the actual HUD. At the moment, I have the code for the hud_sprite at all the right points in Spriteset Map (i.e. @hud_sprite.dispose, @hud_sprite.update) but the HUD (which is for my evented ABS) doesn't update the health bar unless you go in and out of the menu. In other words, until Scene_Map updates. How can I make the HUD update constantly?

Well, theres my two questions, hope someone can help. Thanks in advance.

Every window must be updated inside a scene, and rmxp changes the scene: scene menu, scene battle, etc. You can add @hud_sprite.update in every scene that affects the HUD, but you'll have to make it a global variable, ie: $game_map.yourHUD.

Anyway, why is your HUD visible during scene_menu?
You can create hide_HUD/show_HUD methods. It'll be handy for battles/ cut scenes where the HUD may be in the way, and it's another way to solve this.
Hide the HUD in scene_menu, and show it when exiting the menu, after the dispose lines. Only call show_HUD if the HUD wasn't hidden when the menu started:
show/hide HUD should look like this:
[rgss]class MY_HUD
attr_reader :hidden
def initialize
@hidden = false
#...
end
 
def update
 self.contents.clear
 return if @hidden
# draw the HUD here
end
 
def hide
@hidden = true
end
 
def show
@hidden = false
end
 
end
[/rgss]
Inside scene_Menu's main, do:
[rgss]hud_was_hidden = $game_map.yourHUD.hidden
$game_map.yourHUD.hide
#...(scene menu's loop)
$game_map.yourHUD.show unless hud_was_hidden
 
[/rgss]

Thanks, but... sorry? Maybe I wasn't clear enough. I have the HUD updating in Spriteset_Map, and that's all you need isn't it? I don't want the HUD visible in the menu, and it's not, what I want is the health bar updating. Heres the script I've edited:

class Sprite_HUD < Sprite

  def initialize

    super

    self.bitmap = RPG::Cache.picture("LMS HUD")

    self.z = 1000

    self.x = 640-self.bitmap.width

    self.y = 480-self.bitmap.height

    @current_hp = $game_party.actors[0].hp

    @current_mp = $game_party.actors[0].sp

    @current_ammo = $game_variables[1]

    @current_weapon = $game_party.actors[0].weapon_id

    refresh

  end

  def refresh

    self.bitmap.clear

    self.bitmap.dispose

    self.bitmap = RPG::Cache.picture("LMS HUD")

    self.bitmap.font.name = 'Lucida Console'

    self.bitmap.font.size = 18

    x = 19; y = 21; width = 103; height = 10;

    percentage = @current_hp / $game_party.actors[0].maxhp.to_f

    barwidth = width * percentage

    self.bitmap.fill_rect(x, y, width-barwidth, height, Color.new(0, 0, 0))

    x = 19; y = 41; width = 103; height = 10;

    percentage = @current_mp / $game_party.actors[0].maxsp.to_f

    barwidth = width * percentage

    self.bitmap.fill_rect(x, y, width-barwidth, height, Color.new(0, 0, 0))

    image = RPG::Cache.icon($data_weapons[@current_weapon].icon_name)

    self.bitmap.blt(120, -15, image, Rect.new(0, 0, 96, 96))

    self.bitmap.draw_text(125, 38, 58, 32, @current_ammo.to_s, 1)

    self.bitmap.draw_text(145, 38, 58, 32, "/", 1)

    self.bitmap.draw_text(165, 38, 58, 32, "12", 1)

  end

  def update

    if @current_hp != $game_party.actors[0].hp or @current_mp != $game_party.actors[0].sp or

          @current_ammo != $game_variables[1] or @current_weapon != $game_party.actors[0].weapon_id

      @current_hp = $game_party.actors[0].hp

      @current_mp = $game_party.actors[0].sp

      @current_ammo = $game_variables[1]

      @current_weapon = $game_party.actors[0].weapon_id

      refresh

    end

  end

end

 

 

And here's what I have Spriteset_Map like:

Now, this works, but it doesn't update when you loose health until Spriteset_Map refreshes. As for what you've said about turning the script on and off, where would that go?

 

[silver wind]

Sorry, I thought you said it doesn't update until you close the menu, which isn't a problem unless your HUD is visible on the menu. :p

I tested your script, and.. it works perfectly??
When you lose HP/SP on the map, refresh is called and the 2 black bars get bigger.(The hp/sp bars are part of the hud pic, I guess?) Anyway, I tested it in a new project, so the problem may be an other script/ the evented ABS.

 

[Luthur]

Ah, really? Oh yeah, never thought it could be something conflicting... Well, it was one of my antilag scripts, which I've now deleted, and it works fine now. Thanks anyway. Can anyone answer my second question please?

 

[silver wind]

If it's weapon(not armor, etc):
[rgss]# id : id of the weapon
$game_party.actors[0].equip(0, id)
[/rgss]
