WIP Custom Graphical Command Window!

[dagarath]

Alright I am working on a custom graphical command window, I am new to RGSS so I was hoping people could check the syntax for me to see that everything is correct. I will update the code as I go.

 

class Window_Graphical < Window_Selectable

 

  def initialize(width, commands, bmpheight, bmpwidth, hspacing, vspacing)

    #If vertical spacing is not provided, derive from horizontal spacing

    if vspacing == nil 

      vspacing = hspacing

    end

    

    #Calculate total commands width.

    @commands_width = (commands.size * (bmpwidth + hspacing))

    

    # Check that the bitmaps provided are not wider than the window width

    if @commands_width + 32 > width #If bitmaps are wider

      @lines = @commands_width / width #create lines

      @commands_height = (commands.size / @lines) * (bmpheight + vspacing) # Find window height

      super(0, 0, @commands_width / @lines, @commands_height)

    else    

      super(0, 0, @commands_width, @commands_height)

    end

 

    @item_max = commands.size

    @commands = commands

  end

...

 

  def draw_item(index)

    rect = Rect.new( @commands_width / @lines , @commands_height * @lines, bmpwidth, bmpheight)

    bitmap = RPG::Cache.picture(commands[index])

    self.contents.blt(index * @commands_width , index * @commands_height, bitmap, rect) 

  end

end

 

It is missing quite a bit but it is a WIP. I really need help with blitting bitmaps, it may just be lack of sleep but atm I am drawing a total blank. I am gonna head to sleep and pick this up tomorrow night.

Quick glance.... looks ok so far. I assume "commands" in the initialize argument is an array of bitmaps??

Line 29: missing a @

You must be tired... what is "blitting"?

I think this line: self.contents.blt(index * @commands_width , index * @commands_height, bitmap, rect)
will give you something like:

 

Command 1

                Command 2

                                 Command 3...

 

[dagarath]

too true, I will have to put an if statement in, and some sort of math for that lol

Blit = BLock Image Transfer "To copy a large array of bits from one part of a computer's memory to another part, particularly when the memory is being used to determine what is shown on a display screen."

 

[Brewmeister]

Gotcha... it's like you read "blt", pronounced it in your head, then transliterated the colloquialism back into writing. I missed the verbal pronunciation...

Anyways, use the modulus operator to determine the x position

x = index % (# of items in a row) * item.width #item being a menu item
y = index / (# of items in a row) * row.height

EDIT: Updated again

 

class Window_Graphical < Window_Selectable

 

  def initialize(width, commands, bmpheight, bmpwidth, hspacing, vspacing)

    #If vertical spacing is not provided, derive from horizontal spacing

    if vspacing == nil

      @vspacing = hspacing

    else

      @vspacing = vspacing

    end

    

    #Calculate total commands width.

    @commands_width = (commands.size * (bmpwidth + hspacing))

    @bmpheight = bmpheight

    @bmpwidth = bmpwidth

    @hspacing = hspacing

    # Check that the bitmaps provided are not wider than the window width

    if @commands_width + 32 > width #If bitmaps are wider

      @lines = @commands_width / width #create lines

      @commands_height = (commands.size / @lines) * (bmpheight + vspacing) # Find window height

      super(0, 0, @commands_width / @lines, @commands_height)

    else    

      super(0, 0, @commands_width, bmpheight+vspacing)

    end

 

    @item_max = commands.size

    @commands = commands

    refresh

    self.index = 0

  end

  

  def refresh

    for i in 0...@item_max

      draw_item(i)

  end

  end

 

  def draw_item(index)

    x = index % 3 * (@bmpwidth + @hspacing) #item being a menu item

    y = index / 3 * (@bmpheight + @vspacing)

    rect = Rect.new( x, y, @bmpwidth, @bmpheight )

    bitmap = RPG::Cache.picture(@commands[index])

    self.contents.blt( x, y, bitmap, rect )

  end

end

 

calling it using
$window=Window_Graphical.new(300, ["male01","male01"], 65, 45, 6, 6)

Missing a " in the call

I am totally retarded with this stuff, I wish there was a good tutorial on resizing selectable menus and removing text lol.

 

[Brewmeister]

you never created a 'contents' object. in initialize...

self.contents = Bitmap.new(width - 32, height - 32)

 

[dagarath]

thanks Brewmeister, math I am good at... graphical stuff I have never even really understood in any language lol.

Now it manages to show me an image, but the window is not active, nor is it the right size. I think I should give up on this for a while, I could already have one of my other more important systems complete by now =/

Last version of the code....for now

 

class Window_Graphical < Window_Selectable

 

  def initialize(width, commands, bmpheight, bmpwidth, hspacing, vspacing, columns)

    #If vertical spacing is not provided, derive from horizontal spacing

    if vspacing == nil

      @vspacing = hspacing

    else

      @vspacing = vspacing

    end

    

    #Calculate total commands width.

    @commands = commands

    @commands_width = (commands.size * (bmpwidth + hspacing))

    @bmpheight = bmpheight

    @bmpwidth = bmpwidth

    @hspacing = hspacing

    @lines=1

    # Check that the bitmaps provided are not wider than the window width

    if @commands_width + 32 > width #If bitmaps are wider

      @lines = @commands_width / width #create lines

      @commands_height = (commands.size / @lines) * (bmpheight + vspacing) # Find window height

      super(0, 0, @commands_width / @lines, @commands_height)

      @column_max = @commands.size / @lines

    else    

      super(0, 0, @commands_width, bmpheight+vspacing)

    end

    self.contents = Bitmap.new( width - 32, height - 32)

    @column_max = columns

    @item_max = commands.size

    @commands = commands

    refresh

    self.index = 0

  end

  

  def refresh

    for i in 0...@item_max

      draw_item(i)

  end

  end

 

  def draw_item(index)

    x = index % (@commands.size / @lines) * (@bmpwidth + @hspacing) #item being a menu item

    y = index / @lines * (@bmpheight + @vspacing)

    rect = Rect.new( x, y, @bmpwidth, @bmpheight )

    bitmap = RPG::Cache.picture(@commands[index])

    self.contents.blt( x, y, bitmap, rect )

  end

end
