Thanks, Korakurider, Karl and Yoshiki for the answers to my previous questions. Here is the next set:

  1. What is the purpose of the variable Type: ButtonPhase (ie: how and where can I use it)? 
    A Type with the following possible values: button down, while pressed, button up
  2. In the documentation I wrote: " In Etoys the terms Player and Object basically mean the same thing."  Is this accurate or does Player have a special meaning?
  3. For Type "Point" you can enter a single number (ex: 100) which if you try and use it to set an object's location will throw an exception:
    An error has occurred in
    script5 of Rectangle.
    Fix your script(s), hit 'Abandon' and try again.
    If you enter an "incomplete point" ex: @100 or 100@ you get a "Syntax Error" "Nothing more expected ->@00"

     

    Thanks, Stephen
