Uploaded 5/18/2018 3:54 AM by Dacicus (see all 26)
This script draws the position of the elementals during the final fight with Malkil in Ironsword: Wizards & Warriors II on a canvas. Kuros's position also is drawn. To keep it compact, coordinates on the canvas are scaled to half the value in the game. By default, the area drawn is 1.5 by 1.25 screens large and focused around the middle peak of Icefire Mountain.
Keys are defined that allow you to toggle each elemental on/off, restore Kuros to full health or full magic (so you do not need separate cheats), and clear the canvas. There are toggles for the health restoration, magic restoration, and canvas clearing to be done automatically.

   This script draws the position of the elementals during the final fight with
   Malkil in Ironsword: Wizards & Warriors II on a canvas.  Kuros's position
   also is drawn.  To keep it compact, coordinates on the canvas are scaled to
   half the value in the game.  By default, the area drawn is 1.5 by 1.25
   screens large and focused around the middle peak of Icefire Mountain.

   Keys are defined that allow you to toggle each elemental on/off, restore
   Kuros to full health or full magic (so you do not need separate cheats), and
   clear the canvas.  There are toggles for the health restoration, magic
   restoration, and canvas clearing to be done automatically.

   Mostly by Dacicus in May 2018 but with input processing code copied from
   another script, original author unknown.
