Hashes?

Hey guys, first off, the script:

#==============================================================================#
#  Script: Keyboard Input                                                      #
#------------------------------------------------------------------------------#
#                                                             Author: Zanifer  #
#                                                                Version: 1.0  #
#==============================================================================#
module Input
  Keyboard = {}
  Keyboard["Pause"] = 0x13
  module_function
 	def Triggered?(Keyboard.keys)
		Win32API.new("user32","GetAsyncKeyState",['I'],'I').call(Keyboard.keys)
	end
end
if Input.Triggered?('Pause')
	p 'Hello World!'
end

Ok, when I run it, for the life of me, I either screw up the hash itself, or can't recall the key cause it cant convert the string to an integer, in this case, 0x13. Furthermore, is it possibly an error with the I's in the Win32API?

Thanks

Okay.
First, you should create an instance or a variable for that API. So that you don't initialize it each frame. And why put Keyboard.keys in the method's argument, just a little word will do right. I put 'key' for my example. Also the API was correct but you can also do it as below, it's up to you.

module Input
  GAKS = Win32API.new('user32', 'GetAsyncKeyState', 'I', 'I')
  Keyboard = {}
  Keyboard['Pause'] = 0x13
  module_function
  def triggered?(key)
    GAKS.call(key)
  end
end

if Input.triggered?('Pause')
  p 'Hello World!'
end

Ok, see, Ive tried it as such, and tried it again now. I rewrote some of it so now it looks like this:

#==============================================================================#
#  Script: Keyboard Input                                                      #
#------------------------------------------------------------------------------#
#                                                             Author: Zanifer  #
#                                                                Version: 1.0  #
#==============================================================================#
module Input
  GetAsyncKeyState = Win32API.new('user32', 'GetAsyncKeyState', 'i', 'i')
  Keyboard = {
  'Backspace' => 0x08,
  'Tab' => 0x09,
  'Enter' => 0x0D,
  'Shift' => 0x10,
  'Leftshift' => 0xA0,
  'Rightshift' => 0xA1,
  'Ctrl' => 0x11,
  'Leftctrl' => 0xA2,
  'Rightctrl' => 0xA3,
  'Alt' => 0x12,
  'Leftalt' => 0xA4,
  'Rightalt' => 0xA5,
  'Pause' => 0x13,
  'Capslock' => 0x14,
  'Esc' => 0x1B,
  'Spacebar' => 0x20,
  'Pageup' => 0x21,
  'Pagedown' => 0x22,
  'End' => 0x23,
  'Home' => 0x24,
  'Left' => 0x25,
  'Up' => 0x26,
  'Right' => 0x27,
  'Down' => 0x28,
  'PrtScr' => 0x2C,
  'Ins' => 0x2D,
  'Del' => 0x2E
  }
  module_function
  def Triggered?(key)
		GetAsyncKeyState.call(key)
	end
end
if Input.Triggered?('Pause')
  p 'Hello World!'
end

Yet, I still receive the syntax error "cannot convert String into Integer".

EDIT: BTW, I placed keyboard.keys into the argument thinking it would access the hash.keys and use the assigned value rather then treat it as a string. Would it just be easier to not use hashes and replace em with variables?

There are two ways to solve this problem.
1. Input.Triggered?('Pause') => Input.Triggered?(Input::Keyboard['Pause'])
2. GetAsyncKeyState.call(key) => GetAsyncKeyState.call(Keyboard[key])
