Window Problem

[ArcanaMagek]

Hello,

I'm trying to add a window to a minigame in my project, but it always says:

Failed to create bitmap

It's with this lines:

  #--------------------------------------------------------------------------
  # * Create Window Contents
  #--------------------------------------------------------------------------
  def create_contents
    self.contents.dispose
    self.contents = Bitmap.new(width - 32, height - 32)
  end

Thanks in advance

whats the width and the height of the window?

 

[ArcanaMagek]

class Window_Points1 < Window_Base
  
  attr_reader :points
  
  def initialize
    super(0, 0, 0, 0)
    if $game_switches[1]
      self.x = 0#640 - self.width
      self.y = 0
      self.width = 96
      self.height = 64
      self.contents = Bitmap.new(width -32,height -32)
      @points = 0
    end
    refresh
  end
  
  def refresh
    self.contents.clear
    self.contents.draw_text(0, 0, 64, 32, $game_variables[1].to_s + " Hits", 2)
    @points = $game_variables[100]
    return
  end
  
end

width isn't the same thing as self.width, which is what it looks like you're intending. Same thing with height.

Sorry, I don't understand this

BwdYeti said that

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

means something else than

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

You use:

super(0, 0, 0, 0)

Which mans that you want to create a window at position 0,0 and sizes 0,0. Looking in window_base(where 'super' leads) those are variables called x, y, width, height
and when you use code:

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

you tell:
Create bitmap using sizes 0-32,0-32 and this bitmap cannot be created.

There are two ways to solve your problem
1st: Just change the line to

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

2nd: Change line to

super(0, 0, 96, 64)

And delete lines:

self.x = 0#640 - self.width
self.y = 0
self.width = 96
self.height = 64

 

[SephirothSpawn]

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

Is the same this as

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

As long as width is not a defined local variable before the line is called. Ruby first checks for a local_variable, then a method if a local isn't defined. The object being a window, there is a method width/height. self is really never needed to be defined within a class, unless accessing a class method (which are rare).

With what you posted above, that error shouldn't be happening (unless its VX, and VX's window class has trouble with super(0, 0, 0, 0), not creating a bitmap correctly).
