# This snippet will allow you to show 1 variable in a window at the top-right

module VarWindow
  
  VAR_NAME_1 = "Score:" # The name for the 1st variable shown. You can change it
  #to anything you want, but keep the name inside the quotation marks or it won't
  #work.
  

  VARIABLE_1 = 1 # Variable shown for VAR_NAME_1
  

  ALLOW_TRIGGER = false # Let the player hide the window by pressing a button? if
  #you do want for the player to be able to toggle the score on/off then set this
  #to true instead.
  
  HIDE_WINDOW_BUTTON = Input::CTRL # If true, what button? You can change what 
  #button you want to use to toggle the score to be hidden. 
  
  
  SWITCH_TO_SHOW = 5 # This is the switch that needs to be on to show the window.
  #Just change the number to match the corresponding switch.
  
  OPACITY = 0 # This is how transperant the window is. 0 is fully transperant. 
  #If you want it partly transparent try about 160 or so. 250 is fully opaque.
