in reply to Pentris - a Tetris clone

I have patched the code to toggle the grid and added it to the menu. Most of the text is now in English as well. A couple of notes:

  1. Most of your functions take args $mw,$fld,$width,$height,$C{rows},$C{cols},$C{rowpix},$C{colpix} - passing these as an object or just in the %C hash would make sense - they are all effectively constants AFAIK.
  2. You have lots of code that essentially does just this: die "function X did not get Y arguments!\n" unless @_ == Y except you are using unless .... and .... and .... and ....

Here is the code (sorry to get it to fit within the space that PM allows I had to strip the comments out)

Control: Left Arrow: Stone to the left move Right Arrow: Stone to the right Up Arrow: Stone rotates Down Arrow: Stone a row downward move Space bar: Stone freefalls F2: New Game Pause or p: Pause/Resume You can select from either the classic Tetris where 4 blocks form +a stone or Pentris where up to 5 blocks may form a stone.
